  • 2. Activity-based Learning Experiences in Quantitative Research Methodology for (Time-Constrained) Young Scholars - Course Design and EffectivenessThe paper investigates the reaction of PhD students and junior faculty to a six-month coursein Survey Research Methodology (in particular, supply chain management and entrepreneur-ship) that used active learning experiences. Noteworthy is that the course was tailored to anaudience with variable previous knowledge, interests, available time, cultural background,research and writing skills. Thus, a major challenge was presenting an intimidating quanti-tative course while bridging variation in learner backgrounds. Here we present the coursedesign and its effectiveness. Empirical evidence indicates that an active learning approach ismore successful than the traditional technique-based course and exam format. We analyzedlearning preferences, overall knowledge and skills acquired, and degree of satisfaction -before, during, and after the course. Although the efforts of tailoring the course to aheterogeneous group are substantial, the benefits outweighed this. Each participant was notonly engaged in complicated statistical methods, but also developed lifelong empiricalresearch skills. 1
  • 3. 1 IntroductionActivity-based learning (ABL) is a successful teaching model in the field of medicine,engineering and science, and it has recently found its way to business schools. At its core,this approach provides a way to integrate learning within students’ knowledge, and, byexposing them to a variety of activities, helps them learn how to learn. Due to the high degreeof interaction in ABL, essential instructor skills involve facilitating, motivating, enabling andcoaching rather than simply presenting facts and figures didactically.In this paper, we describe how we implemented ABL experiences in a newly-developedAdvanced Quantitative Research course targeting Chinese PhD students and junior faculty. Inorder to enable participants to see its relevance, we selected ABL for two principal reasons:first, doctoral students are naturally involved in investigating, discovering, and interpreting;secondly, we focused on operations management problems because China has becomevirtually the world’s factory. To our knowledge, this is the first course in this field at auniversity in China entirely taught by a scientist without Chinese heritage.Implementing an “innovative” teaching approach is only successful when the specific infra-structure and student situation are considered. Thus, a modified teaching ‘strategy’ must becarefully developed. Given this context, the article describes: 1. the key principles for the ABL teaching approach, 2. chief activities nurturing and fostering ABL experiences, and 3. how ABL impacts the effectiveness of the course. 2
  • 4. 2 Activity-based LearningIn a ‘traditional’ class there is a perception that the most industrious students are those whopassively soak up everything the teacher might serve up to them in a suitably ‘didactic sauce’only to ‘spout it’ back word-for-word. It was important, therefore, at the beginning of thecourse, in the introductory lecture, to stress that participants do not need to repeat thingslearned word-for-word. Rather we expressed our vision that students evolve into“investigators”, starting an independent inquiry into a topic of interest in a self-directedmanner. Consequently, facilitating, motivating, enabling and coaching are the key skill-set ofthe instructor (facilitator) rather than just didactic lectures. At the beginning of the class, weillustrated ABL with a famous saying of Confucius that stresses participation as the key tostudents’ learning success (see Figure 1): “Tell me, and I will forget, 听到,我会忘记, Show me, and I may remember, 看到,我会记住, Involve me, and I will understand.” 参与,我会明白。 Confucius 孔子 Figure 1: Teaching Style as outlined by ConfuciusThere are numerous individual learning theories attempting to find answers to the problemsof helping students learn and adapt to new situations; two stand out: behaviorist theory (B.F.Skinner) and cognitive theory (Jean Piaget). Behaviorist theory states that knowledge existsindependently and outside of people, i.e. only small bits of information are transferred tolearners, with learning success achieved only when a connection is established between astimulus and a response (credited to the work of B.F. Skinner). The second theory, 3
  • 5. cognitive theory, stresses the importance that learning is a result of the interaction of aparticular structure and a person’s own psychological environment. In this theory, learningmodifies the students “world of knowledge” by interaction processes, so that he or sheacquires new insights or changes old ones.Activity-based learning (ABL) theory is a cognitive-learning theory which is considered a“constructivist” learning theory (Hein, 1991). Essentially, a learner “constructs” his ownmicrocosms of knowledge from past knowledge and/or current experiences and interactingwith data. He or she actively seeks new information, and is actively engaged in the process inthe way s(he) gains, assimilates, and utilizes knowledge. The facilitator engages learners inoutlining real-world problems in the first place instead of starting with a classification ofproblem-solving methods. (Therefore, the theory is also referred to as problem-based learningtheory). Integrating ABL elements is thus a promising way to enhance students’ learningexperiences. Vital learning principles include (Figure 2, see in detail Hein, 1991):Learning is an active process: A student needs an input of “doing”, and is engaged with the world, from whichthe learner constructs a meaning, as well as systems of meaning.Learning is engaging: Teachers need to provide activities that engage the mind as well as the hands.Learning is a social activity: Learning experiences are connected with other human beings (e.g., teachers,peers).Learning occurs contextually: Learning experiences are interwoven with life experiences.Learning builds on previous knowledge: Teachers efforts must be connected to the state of the learner andprovide a path into the subject based on his/her previous knowledge or experience.Learning takes time: Students need to revisit ideas, ponder them, try them out, play with them, and use them. Figure 2: Intended Course Schedule and realized Course ScheduleABL is not a completely new teaching style because it can be traced back at least as far asSocrates and Humboldt. However, it has been rediscovered by progressive educators such asJohn Dewey (Dodge, 1998). For a long time, it seemed that universities neglected to think 4
  • 6. about the process of learning, since it is a highly active process in which it is imperative toconvince students to speak, read, write, and think deeply (Dodge, 1998). “The thinkingrequired while attending class [traditionally has been] low level comprehension that goesfrom the ear to the writing hand and leaves the mind untouched” (Dodge, 1998). In contrast,the success of ABL is to make students feel responsible for their learning and to support theirown individual development (Cohen, 1990).For several years ABL has been implemented in teaching-learning curricula in a variety ofsettings from private schools (e.g., Montessori schools) to universities. Applications can befound in medicine, science and engineering and more recently, also in operations manage-ment classes (e.g., Kanet and Barut, 2003). Recently, the Harvard Business School evencreated a committee on activity-based learning aimed at integrating students’ extracurricularactivities with their academic experiences in the classroom.There is little relevant scientific literature about statistics courses in operations management(OM) addressing specific needs of PhD students in transitional economies. However, we canbuild on the experiences made by Burton (2003) reporting on typical problems of statisticsclasses at the PhD-level in Australia. For example, instructors cannot take for granted thatstudents have advanced skills in data collection, particularly in developing surveys, or welldeveloped skills in formulating a specific hypothesis. “Empirical Research in OperationsManagement” - a course established by Charles J. Corbett (Decisions, Operations andTechnology Management), Anderson School of Management at the UCLA (University ofCalifornia, Los Angeles) - has similar objectives to our course. However, given that specificlearning environment, Corbett spent about half the course time critiquing empirical papers inOM, emphasizing the logical correctness of the study and the underlying empirical researchmethods, and the preparation of an empirical term paper. With efforts to reform university 5
  • 7. teaching in China, Chinese scholars support the notion that the traditional (passive) way oflearning is not sufficient since companies have changed in terms of what they require fromstudents. Instead, participation and giving students the time to explore issues is vital to long-term success in China. Therefore, Chinese universities want to promote dualism and offeractive learning experiences (Sun and Zhang, 2007; Che, 2008).3 Description of the Course and its Activities3.1 Course Duration and RequirementsThis course was part of the PhD program offered to doctoral students and junior faculty at theSchool of Management at Jilin University (JLU), a leading University in China (The hostuniversity is shortly described in Appendix 1). The course is part of the universityscontinuing effort to expose young scholars to the work of international scientists.The course was offered to a limited number of students (up to 50) ten double sessions; it tookplace at the end of the week from 1:30pm to 5pm. To allow time for content repetition andadditional group work, sessions were often extended from 210 to 270 minutes. Altogether,each student received around 42 hours of instruction. It is worth noting that the teaching timewas extended due to additional one-on-one training during office hours which gave partici-pants the opportunity to share their experiences, the problems encountered in research metho-dologies and to discuss possible ongoing strategies.In order to provide learning opportunities to all PhD students at every level and juniorfaculty, we did not require any pre-requisites or qualifications. Participants came from allbusiness departments. Recognizing individual time-constraints, it was not expected that 6
  • 8. participants attended all sessions, although they were required to attend at least eight of them.Upon successful completion of this seminar, every participant received a seminar certificate.The course design was presented to faculty for discussion and ratification, and this led to thesuggestion of a short introduction to the roots of European research history. The backgroundof the facilitator is outlines in Appendix 2.As all courses in a PhD program, the course has a tremendous impact on the research qualityand working attitude of the students in regard to their gained doctoral education before theyenter life in business or research.3.2 Learning OutcomesThrough the integration of ABL elements we aimed to enhance learners management know-ledge, skills, and problem-solving abilities. Specifically, upon completion of the coursestudents were expected to have the ability (see Figure 3):To demonstrate awareness of the range of statistical support that is available to scientific researchers, and to beable to apply the ‘right’ techniques at the ‘right’ moment.To exercise critical thinking skills while assessing the quality (e.g., rigor and relevance) of an original scholarlyarticle by identifying strengths and weaknesses.To explain a chosen quantitative methodology and thus strengthen confidence in the application of statisticaltechniques.To communicate professionally to different recipients both in oral and written form.To incorporate information into their own statistical research and show originality in the application of researchmethodologies. Figure 3: Selected Learning Outcomes of the Course 7
  • 9. The aim of this course was not to develop professional empirical researchers, as that wouldrequire a much longer and more intensive program. For example, a typical introductorycourse in Lisrel (a specialist statistical program) takes three full-days of extensive training(see http://www.ssicentral.com/workshops/lisrelbegin.html). Rather, the course objectiveswere to brush-up and broaden the horizons of participants, to introduce them to a range ofresearch methods and paradigms with which they were less familiar. In line with the intentionof ABL, we intended to help participants prepare for further study on the specific methodsthey are conducting, contemplating, or pursuing in their own research projects. As such, wetried to motivate student curiosity about new statistical methods and encouraged the studentsto delve into methods that, due to the scope of the course, could be dealt with only in alimited fashion. Thus, the course stressed life-long learning.We summarized the learning goal presented in the introductory training: “I want you to learnstatistics, but I don’t want you just to understand the concepts - I want you to understandwhere to get the concepts and where they come from.”3.3 Principles of the Course DesignWhile ABL reflects the “philosophy” of the course, we based the course design on thefollowing objectives (see Figure 4) so as to address the specific students’ situation (seesection 2): 8
  • 10. Simplicity: Statistics should be “explained as simply as possible, but no simples” (without “dumbing down”) -we followed Albert Einsteins aim in physics teaching.Modularity: Sessions were designed to be self-contained, enabling time-constrained students the freedom toattend. Repeating essential material at the beginning of the class helped avoid large knowledge gaps.Adaptation: The course was constantly adjusted and refined according to survey instruments, e.g., aboutstudents’ learning preferences.“Modern” teaching style: Learners were exposed to ABL as the state-of-the-art teaching style, stressingreflective inquiry through questioning and reflection.Advanced teaching material: The content of the course focused on techniques as predominantly applied in theNorth American and West European research community, in particular in the POMS and Informs community.The inclusion of material rarely found in normal textbooks, and mainly only from published articles, facilitatedexposure to and acquaintance with cutting-edge research.Breadth and comprehensiveness of the course: While introducing a range of empirical methods includingrequired methods (e.g., structural equation modeling), we ensured that all students received a well-roundededucation in fulfilling the requirements of a modern PhD program.Total human development: The course fostered not only intellectual development but also social skills (e.g.,networking among students and faculty), and the acquisition of soft skills such as giving presentations anddefending ideas. Figure 4: Selected Design Principles of the Course3.4 Selected Contextual Factors of the LearnerA doctoral-level statistics course presents a challenge for both students and instructors.Typically, there is a wide range of student skills, different levels of previous knowledge, andvarying interests. When a course is compulsory, a dislike of statistics or even a phobia ofmath may add to the complexity.Given the specific environment in which we were teaching, we had to anticipate cultural-induced challenges in our course design. Typically, students in China were accustomed tobeing taught in often-overcrowded classrooms in a more authoritarian teaching style, whichmeant student questioning and lively discussions were rare. As a consequence, our partici-pants typically learnt and acquired knowledge and skills as the result of observation, recall, 9
  • 11. memory, imitation and replication. This is in contrast - even diametrical - to education inNorth America and Western Europe, which is traditionally based on a teaching style whichfosters independent research, critical thinking, and participation and discussion in class. Thus,the biggest challenge for us was how to bridge the gap from previous cultural notions andexpectations of Chinese education with a new ABL approach in course participants learningexperiences. The facilitator’s previous experience with domestic and non-domestic Chinesestudents helped to cope with these special factors.To gain a composite picture of the student situation and to fine-tune our pedagogical strategy,we administered a survey in the first session before the training started to assess teachingpreference, knowledge of statistics and problem-solving skills. Students rated various state-ments on a 1 to 5-point Likert scale ranging from “strongly agree” to “strongly disagree.” Weevaluated the responses of 39 participants. The following provides a rough impression of thequestions covered.1. Overall knowledge in Questionnaire Development Process and Survey Research: By and large, the overall comprehension about surveys was good. 74% of course participants strongly agreed, stating that prior experiences prepared them to develop questions for a survey. Similarly, it helped them understand the variety of research methodologies. However, one out of four PhD students and junior faculty disagreed with the propositions that they gained experience in accurately performing business calculations (indeed this item received the lowest mean in this construct/area).2. Knowledge and Higher Empirical Skills: As expected, empirical skills were not developed to any great extent. A little more than half the participants felt prepared by former courses in applying statistical interference hypothesis tests and predictive analysis (e.g., 10
  • 12. regression). Nearly one in two respondents stated that they did not gain skills in applying differences tests (e.g., ANOVA) and advanced methods such as SEM (Structural Equation Modeling) or PLS (Partial Least Square) Modeling. It seemed that, similarly to the U.S., participants focused on analytical methods and case methods (“Operations Research approach”) and not on empirical research.3. Problem-solving Skills: A mixed picture was gained in this area. While the majority of the students had no problems in searching information in electronic databases, one person in three experienced difficulties when retrieving information from literature that is not available electronically. Participants felt very well prepared in working efficiently in teams and taking responsibilities for a process or specific result (teamwork). The lowest mean value was observed in the use of creativity techniques in team meetings (i.e., brainstor- ming); every third participant identified insufficient skills in that particular area. The highest standard deviation was observed for the item “evaluating a published paper”, and this reflected the different student levels in the course.4. Linguistic Skills: Proficient linguistic skills in English were expected although students had widely varying English oral and writing skills. 48% of the students agreed that prior courses fostered oral presentation skills while 45% disagreed - nearly none of the students remained ‘neutral’ on this issue. Three out of ten students identified a lack in their business-writing skills. There are many reasons for this. As in many Chinese universities, students have compulsory English classes and are exposed to English Powerpoint slides in “bilingual courses” (which, however, are usually taught in Mandarin) but this resulted in variable levels of English proficiency. Some students had returned from visiting positions in the U.S. or Germany. 11
  • 13. 5. Preferences in Teaching Style: In business education, five different generic teaching styles can be distinguished - see at length Stößlein and Kanet (2008) who applied problem-based learning in SCM with undergraduate students. The highest preference was given to a teaching style that outlined a problem, before applying possible methods and finally a solution approach (80% of the students agreed). By contrast, the pedagogical strategy - that starts by explaining methods and exemplifying them in the next steps - was given the lowest preference (although more than 60% agreed). A middle position (although 10% do not regard this teaching style as valuable for life in business/research) went to a teaching style that starts by outlining a research issue and giving students an opportunity to investigate it for several weeks under guidance.6. Degree of Satisfaction with Previous Instructors Way of Interaction: Students in the sample indicated that they are most satisfied with previous instructors who speak slowly and use simple language. More than 60% explicitly wished to be involved in class dis- cussions. As expected learners considered that textbook teaching was the least preferable option that was confirmed by three out of ten students. 55% of the participants in our sample were accustomed to using journal articles.We expected a high number of students to have limited time to prepare or revise coursecontent due to their thesis preparation and involvement in teaching. Despite this, our mid-term survey revealed the great extent to which participants were industrious and eager tolearn. The self-assessment showed that participants prepared or reviewed their work for anaverage of four and half hours per week. They also thought that their classmates spent threehours preparing for each double session (e.g., conduct analysis, review examples). However,this may be partly due to the fact that completing ABL-based projects is more time-con-suming than a traditional technique-based course since ABL forces participants to spend time 12
  • 14. on the ‘right’ questions, and not just to listen to ‘answers’.3.5 Session OverviewIn the course we dealt with a range of topics covering the fundamentals of statistics and“innovative” methods such as the Partial Least Squares approach. We emphasized, however,the methods that are commonly used in supply-chain management research.We constantly adjusted our teaching program since it was part of our goal-shifting from apredefined technique-based learning to an activity-based learning course grounded inlearners’ needs, expectations, actual research problems and situations. For example, it turnedout to be useful to repeat how to interpret statistics and to insist on further analysis of whygraphs found in newspapers are sometimes misleading. Furthermore, we found out that lesscontent can bring students a greater understanding of what empirical research really is allabout. Therefore, we did not cover structural equation modeling to any great extent but onlyintroduced the basics.The following Figure 5 illustrates two session overviews - the original one and an updatedone that we adjusted in order to allow for the specific students’ needs and situations (see sec-tion 2). 13

Each student was expected to take part in several activities, all contributingto understanding the nature of research methodologies in general and, specifically, to excel inthe particular techniques that were required for an individual participant’s research success.In the following, we describe and comment on the courses road map (see Figure 6) andselected class activities.

Final report Figure 6: Milestones of the ABL-based Course3.6.1 Methods and Skill TrainingsEach session reflected three different course levels. The first part of each session, around 15-20 minutes, recapped the essentials from the previous lecture. The second part of each sessionprovided explanation of the theory underlying each technique. This introduced students with-out previous relevant knowledge to the theoretical background, whilst enabling experiencedstudents to brush up their skills. Basically, this covered undergraduate and graduate coursework while avoiding teaching in the standard “cookbook” format. Instead we used thetechnique of “storytelling” that interweaved statistics with historical notes on famousstatisticians, everyday examples, individual experiences from the instructor, and so forth. Thethird part of each session was aimed at making participants intelligent users of thesetechniques so they could apply them in their own research, interpret the results and criticallyevaluate research done by others.Before each session, students received “lecture notes” (part of a script) by email. The scriptwas not intended to be a substitute for the training sessions. Rather its purpose was to 15
  • 17. save students time and effort in taking notes. Nevertheless, students were required to providetheir own remarks or to do calculation exercises. To ease the understanding of keyexpressions, we translated around 20-30 key words from English to Chinese at the end ofeach script chapter.The first lecture aimed to immerse students into the role of a statistical researcher, tointroduce types of research and the pedagogical strategy of the course (see outline of firstsession in Figure 7). For example, in a historical sketch we outlined what research meant toSocrates, Aristotle, Descartes, Planck and Heidegger, to name but a few. In terms of the focuson supply-chain management research, we highlighted an article by Gupta and others whoinvestigated which types of articles were published from 1992 to 2005 years in the POMSJournal; this revealed that articles based on empirical data have increased substantially, from30 to 50 percent. This also enabled us to introduce the most frequently used data-analysisapproaches. For survey process, we highlighted the fact that mistakes made in data collectionand analysis were nearly impossible to correct at a later stage; this gave students some intro-ductory tips for avoiding time-consuming mistakes in data analysis. In addition to thisacademic content, we also made time to introduce each other in English and Chinese. Finally,expectations about the course were recorded with a questionnaire.

  • 18. In the following lectures, all phases of the “life cycle” of a typical empirical research projectwere covered. The second session dealt with the collection of data, enabling the students todevelop a research design, formulate research questions and/or hypotheses in a clear andconcise fashion, to effectively and efficiently prepare survey questions, to collect and accessdata.From the third session on, we aimed at analyzing data with statistical techniques, to interpretresults, to formulate relevant conclusions. We covered topics such as the analysis of multi-variate data. For example, we sequentially introduced structural equation modeling (SEM),e.g., measured variable path analysis, confirmatory factor analysis (and related topics such asconstruct validity/reliability), and latent variable path analysis. We also included discussionson multi-group analyses and practical guidelines on how to present SEM results insubstantive manuscripts.3.6.2 Calculation Exercises in ClassTo assist participants in building a personal library on calculation expertise, instructor-prepared handouts with exercises were distributed during class sessions.Besides calculation exercises, we offered multiple-choice quizzes (with three to five possibleanswers) both at the end of the session and also spontaneously during the class. Quizzes weredeveloped in such a way that they played more of a learning role than just assessment.Students were allowed to answer in groups of three to five. From time to time, we alsoconducted group competitions. To assure that the average knowledge level in each group wassimilar, the instructor made sure that one or two “statistics whizz-kids” were placed in eachgroup.There are many advantages to this kind of class activity. First of all, quizzes assist active 17
  • 19. learning by supporting both the personal construction of understanding and mastering of theteaching material. Secondly, quizzes contain intrinsic feedback, i.e. participants get to knowhow close they are to performing well or underperforming. Third, the group formation makesstudents talk about things they have learned, share experiences, and explain or recap materialin their own words. Finally, group competitions gave additional motivation to participate inthe class activity and thus build self-confidence.The following Figure 8 illustrates selected activities.Activity 1: Comparing family incomes, employee income, Super Bowl winners, social class and first jobActivity 2: Describing annual research and development expendituresActivity 3: Describing sales figures, evaluating the performance of funds, department store survey,Activity 4: Predicting car sales, cold remedies, survey among dog owners about pet food, improving customerservice data from a auto online-websiteActivity 5: Comparing habits of online and offline newspaper readers Seat belts safety, analyzing differences inLifestyles between countries, Predicting car purchases, fast-food sales, car sales and average salary,Advertisement for restaurant, Cold remedies, comparing upscale sedans and reliability,Activity 6: Monitoring fill rates of boxes, failure times for hardware components, analyzing waiting time infast-food chain, decision on purchasing a maintenance contract, defective parts in inspection process,determinants of home values, process control with computer supplies, student performance indicators, analyzingtime needed to mix a batch of material,Activity 7: Job satisfaction rating for employees, company recruiters on campus, analyzing managerexpectations, past academic achievements and present achievements, family size and abilities Figure 8: Selected Activities3.6.3 Scholarly Readings and DiscussionOne of the core questions we examined in this class activity was what constituted good(quantitative) research by discussing the merits of excellent papers compared to less rigorouspapers. Papers were summarized with abstracts, hypotheses and methods (e.g., path model) -see the following Figure 9. 18

Figure 9: Summaries of a Scholarly Manuscript for Discussion3.6.4 One-Minute-, Two-Minute-, Five-Minute-PresentationsEach participant was expected to provide several presentations covering his or her researchfield(s) including their primary research questions, as well as a favorite (empirical or non-empirical) article and his or her ideal scientific researcher.Course participants evaluated their peers with the help of a short assessment sheet. As anincentive, presenters received “bonus points” in their course assessment.

  • 21. 3.6.5 Paper ReviewingStudents had the opportunity to switch into the role of reviewer in order to get to know the“other” side of research. We provided checklists about factors contributing to rigor andrelevance and also touched on the rigor-relevance debate. To fulfill the needs of this hetero-geneous group we covered different research methodologies, in particular, operationsresearch, IS research, and the emerging field of entrepreneurship.Around every second session, students prepared short one-page reviews evaluating recently-published articles. The review was meant to be an analytical critique, rather than merely asummary, and provided several benefits. First, it forced students to study the underlyingempirical research method in greater detail than can be introduced in the classroom. Second,it showed students how papers in different types of journals are prepared. Third, it reflectedthe students own work. Finally, students further enhanced their linguistic skills in writing andpresenting their work.

Many of theassigned exercises required the use of a computer.Noteworthy is that students were provided with an overview of several statistical softwarepackages only after the theory was explained with a calculation example. However, thisapproach frustrated some students who believed that a statistical software program can do theanalysis on its own and who were only interested in the meaning of tests they found in theprogram.We introduced Microsoft Excel add-ons (from text books), SPSS, SPSS Amos, SAS, andLisrel, primarily for new users. Since we used up-to-date software, there was no need tobecome familiar with the command-line syntax used in other software. Contact with severaldifferent statistical software packages made students learn about the strengths and weak-nesses of those packages.The following Figure 12 illustrates selected activities.Activity 1: Survey about preferences in restaurantActivity 2: Analysis of automobilesActivity 3: Evaluating the performance of fundsActivity 4: Predicting car purchases, fast-food sales Figure 12: Selected Activities3.6.7 Individual Research ProjectsSince it is virtually impossible to cover SAS or SPSS Amos with their correspondingstatistical tests in 60 minutes, students had the opportunity to explore techniques and 21

To addressstudents different needs, we also handed out a topic list offered at four levels: beginner,advanced, expert, and professional.For successful completion of the course it was necessary for students to write a short paper(four pages) over the winter break (around eight weeks); in order to do this, they wererequired to specify a research problem, explain possible methods, optionally use a softwarepackage and show the context of their topic in relation to the course content.Students had the opportunity to present a brief statistics problems and solutions session at amini-student conference and a poster presentation after the last session to which faculty,Masters students interested in survey research, and selected business partners were invited.The final papers were handed out as short proceedings and thus shared with other students toincrease their knowledge. Students were allowed to present their papers in English or Chineseor even mixed-language. Awards were given on the basis of the final reports and presenta-tions. (This class activity was not completely finished at the time of the paper submission.)The following Figure 13 outlines the time-line of this activity.

  • 24. We recognized the importance of giving students confidence and motivation by reinforcingtheir strengths and opening up new ways for them to succeed. Accordingly, we providedguidance that was as easy to understand and as pragmatic as possible without neglecting therigor of research requirements. We found that the simplest solution was the provision ofchecklists. Step by step, we started writing an abstract, then a table of contents, etc. Forexample, we delivered timely tips of how to succeed at every stage - such as outlines inFigure 14. In order not to overwhelm participants, we decided to send out these tips sequen-tially: basic, advanced, and professional tips.Business writing tips (e.g., how to write abstracts)Writing exercises (e.g., annotated text samples, developing an argument, summaries and creative statements)Tips of an art studio (e.g., visual design, poster presentations)Presentations tips Figure 14: Selected tipsTimely feedback and various checklists helped participants to succeed. Since the generalconsensus in general learning theory is that students value the opportunity to reinforce theirlearning through interactive resources, we decided to offer this course activity during thewinter break (around eight weeks) when many students are in their home towns and when thefacilitator is in the U.S. Thus, we forwarded the coaching material by email and offeredcommunication via MSN and QQ. By doing this, we also (unintentionally) integrated Online-Activity-based learning elements in a virtual global classroom experience.3.6.8 Team ProjectThe course concluded with team presentations of small quantitative research projects reflec-ting methodological knowledge obtained throughout the course. The focus of the presen-tations were on choosing an appropriate research design, developing hypotheses, preparing an 23
  • 25. extended research abstract using correct terminology, and professionally presenting theproject sketch to a scientific audience with MS Powerpoint. Due to time constraints we usedSPSS data found in a text book. Team awards were given on the basis of the final reports andpresentations. (This class activity was not completely finished at the time of the submissionof this paper.)4 Preliminary Assessment on the Effectiveness of ABL4.1 Student Feedback4.1.1 Study ObjectiveA study examined the impact of ABL upon the course. The major objective of the assessmentwas to determine the extent to which students are in favor of ABL experiences compared to atraditional technique-based course and exam format. Furthermore, results can also improvethe learning experience in subsequent classes.4.1.2 Selected HypothesesWe hypothesize that the adherence of ABL has a positive effect on three constructs (latentvariables) for students: their knowledge, their problem-solving skills, and their self-confidence/satisfaction. As foundation for measuring the effectiveness of ABL serves themodel of Kanet and Barut (2003). The authors have been successfully applied theseconstructs in previous educational research in a related teaching approach, namely problem-based learning among undergraduate students (see Figure 15, which illustrates the path modelfor our final assessment. 24
  • 26. Exogenous variables Endogenous variables Knowledge Adherence Problem solving to ABL skills Self-confidence/ satisfaction Figure 15: Path ModelThe aforementioned course objectives (see section 3.3) represents the ‘measured variables’.However, for our preliminary assessment in this paper, we used each question in our mid-term assessment as a hypothesis. Thus, some of the propositions to be examined were (seeFigure 16):Proposition 1: The ABL component will help to increase participants skills in analyzing survey data. (Construct 1: Knowledge and overall empirical skills acquired in the course).Proposition 2: The ABL component will develop participants oral presentation skills in English (2. Construct: Problem solving skills gained in the course).Proposition 3: The ABL component will develop each participant’s personality step by step, in order to help him or her become an independent learner (3. Construct: Degree of self- confidence/satisfaction). Figure 16: Selected Propositions4.1.3 InstrumentAssessments involved periodic measurements before, during and after the course. It allowedus to conduct a confirmatory factor analysis using Structural Equation Modeling.In this paper, we report on pre- and mid-term ABL surveys and compare those results pair-wise by applying the so-called paired t-test (with α=0.05). (We could only use the pre- andmid-term surveys, because the final sessions of the course have not yet been held due to the 25
  • 27. submission deadline at POMS).We designed a questionnaire with a 5-item Likert scale with response options ranging from“strongly agree” to “strongly disagree.” To ensure understanding, items with statistical keyterms were translated into Mandarin. Although all students were asked to complete the surveyinstrument, participation was voluntary. As all students participated in the survey, non-response bias was not an issue. Demographic data such as age or gender were not collected.4.1.4 ResultsWe present selected early results on the effectiveness of ABL.

I appreciate team work with my colleagues. I enjoy discussions with the instructor in class. I became more and more an independent learner. Legend: [underlined hypothesis] = significantly improved (alpha=0.05)Figure 17: Pair-wise Comparison of Pre-ABL and Mid-term ABL Feedback (Fall 2008 and Winter 2008-09)By and large, this part of the survey showed high achievement levels in the overall programand in specific learning outcomes. In particular, the greatest improvement for students was intheir ability to perform business calculations accurately. Although reading and presentation 26
  • 28. skills improved, business-writing skills have not yet shown any progress. The reason for thisis that although students receive writing tips in form of checklists, they do not experience theextensive one-on-one lessons as provided in business writing classes. The final assessment ofthe course provides further insights into possible improvements.4.2 Facilitator’s FeedbackIt seems that students high level of motivation and eagerness to gain knowledge and to parti-cipate enabled them quickly to adopt and enter into their modified student roles.Due to the limited instruction time and heterogeneous knowledge level, more advanced topicscould not be covered more deeply as had been planned. However, the focus on essentialsbrought students a greater understanding of what empirical research really is all about.Course participants are well-equipped for follow-up training to progress intellectually and togain more specific technical-oriented skills using software packages for Structural EquationModeling or Partial Least Square Modeling. Teaching modules in three two-day workshopsseems a practical way forward.5 Selected Good Practices in Implementing ABL5.1 Instruction-based PracticesBased on our early success with the course format, we provide some ideas as to what seemsto have fostered the participants immersion into their ‘new’ students’ role, as promoted byABL theory. In Figure 18 we outline some good practices for a typical course cycle: 27
  • 29. 1. Planning and adjusting the course prepare lecture notes with translated key words, distributing them some days before the session starts customize statistical problems to the region (e.g., use names of Chinese companies and regions) encourage negotiating aspects of the curriculum with students where it is feasible to do so build course on explicitly interdisciplinary material - in the selection of texts and readings – provide students with a platform to speak and present in English cover simple statistical tests (t-test, Anova) in detail, and move rapidly to a wide range of techniques to generate interest (e.g., structural equation modeling) use an approach that fosters students total development, i.e., cite histories of famous statisticians cater for individual needs in mixed-ability groups to ensure that every student is given the opportunity to participate in every aspect of the learning program build course on interactive collaborative projects both in and outside the classroom coach students with real-world, international examples and SCM scenarios capitalize on students’ publications plans and give them an opportunity to customize their learning to their own development plans.2. Coaching in class practice reading and interpreting misleading statistics (despite the above-average mathematical skills of Chinese students) create a scholarly community among participants, to empathize and to connect (students need to feel part of a supportive group with shared interests) facilitate students development of a sense of commitment to “their” learning programs convince participants of the advantages of doing calculations, writing notes during sessions, formulating questions, and exploring problems on their own reinforce learning experiences by using state-of-the-art statistical programs let student groups explain content to each other in their mother tongue foster competitive situations with group exercises (e.g., quizzes) promote networking among students of different PhD levels “do as the Romans do” - acknowledge habits and speak Mandarin speak slowly, limit colloquial speech, and repeat essential content (the facilitators German heritage helped him to appreciate the difficulties of second-language learners) practice critical-reading exercises, let relevant information identify and key arguments synthesize by being passionate about work, serve as a role model invite students to submit their own “live” problems for course discussion and personal action.3. Evaluating and assessing collect feedback on an ongoing basis (e.g., survey, focus groups, teaching assistants) illustrate the benefits of ABL theory with empirical studies communicate course achievements to faculty and deans Figure 18: Selected Instruction-based Practices5.2 Faculty-based PracticesAnother key factor for success of the course was that the facilitator was allowed indepen-dence, intrinsic incentives and trust to design the course and coach the students. Commitmentfrom faculty and deans was essential. Generous assistance on everyday issues allowed the 28

At its core,the active individual learning experience, enhanced interaction between an instructor andcourse participants, and constant exposure to cutting-edge research taught in a foreignlanguage is unique to PhD students in the given context. The course plays a pioneering roleas it is the first course taught by a foreign instructor at Jilin University, and - to our know-ledge - in survey research methodology at PhD level in China.Given the positive feedback received, it is reasonable to conclude that the modified teachingstrategy seems to be effective. Our teaching approach shows significant improvements forstudents statistical knowledge and problem-solving skills, and also their degree of satis-faction. Equally importantly, participants appreciated the teaching style incorporating ABLexperiences. However, since the assessment of ABL experience is at an early stage, a longi-tudinal study would be appropriate.Although it is a small step in fostering ABL experiences in Advanced Quantitative Research,this course concept could also conceivably be applied to other areas in a PhD program.However, since the detailed course design needs to be constantly adjusted to allow for studentneeds, such a course can take longer preparation time, and requires more effort than teaching 29

Changchun is the 7-million-inhabitant capital city(without urban districts) of Jilin Province. Due to its automotive-industry focus (e.g., FAWcooperates with VW, Toyota, and others), the city is also called the (former) “Detroit” ofChina. In 2007, Changchun hosted the Winter Asian Games.As with all leading universities in China, JLU is under the direct jurisdiction of ChinasMinistry of Education. The university has more than 60,000 students, employs more than3,000 professors and associate professors, and offers 120+ undergraduate programs, 200+graduate programs, and 100+ doctoral degree programs. Recently, the School of Managementorganized the “2008 International Conference on Innovation and Entrepreneurship” incooperation with the Global Entrepreneurial Center of Thunderbird University.Appendix 2: Background of the InstructorThe facilitator has a background in industrial engineering and management, business infor-mation science, and operations management, and has been teaching at the university levelsince 2001. He had published papers on innovative techniques facilitating improvement instudent learning, particularly in research-based operations management education. Moreover,the instructor has an extensive research and teaching experience in China due to his associa- 31
