Abstract This article aims to introduce the study process and outcome of case
learning activity sustained by a web-based case assisted study environment (or WebCASE for short), including the choosing of learning object, the implement-ing of study proposal and the discussion of initial conclusion Our research mainly concerns problems from two levels: one is how to organize case study activities; the other is how to design effective on-line study environment to support case study activities We exactly follow the design-based research pat-tern to improving our research result and conclusion, so we develop two sec-tions of research work, as follows: prototype implementing section, practice research section In prototype implementing section, we study the current situa-tions of popular case databases all over the world and the requirement for online case study environment of users by literature review, questionnaire statistics, and personal interviews Based on the initial requirement, we design and im-plement a prototype system of Web-based Case Assisted Study Environment, WebCASE Research work and results of prototype system implementation can
be found in In practice research section, we study the case study activities sup-ported by WebCASE prototype system, with the course “Industry System Intro-duction” provided by Professor Darong Lu as our reference In this paper, we mainly concern problems in four aspects: first is the study environment, study-ing overall teachstudy-ing effectiveness and main functions of WebCASE; second is learning object, studying how original cases developing in WebCASE systems; third is study process, how to organize case studies under the support by Web-CASE; finally is study evaluation, how to generally and effectively evaluate students’ performance in case study activities

1 Introduction
With the fund of Ministry of Education 10th-five-year Programming Project - “About Network Education Mode and its cross-subject development” from 2003-2006[1], we study the Web-based Case Assisted Study Environment (or WebCASE for short）and its supporting case study activities for a period of two years Our research mainly con-cerns problems from two levels: one is how to organize case study activities; the other is how to design effective on-line study environment to support case study activities
In the purpose of continuously improving our research result and conclusion, we ex-actly follow the design-based research pattern which is an emerging technique all over the world Quantitative research and Qualitative research are two basic types which so-cial science researchers often use, and both of them have been used widely in educational science researches Although these two research patterns differ in philosophy basis, ap-plicable conditions, and operating methods, both of them aim at describing and illustrat-ing learnillustrat-ing and objective phenomena, basic relationship or rules in education area, not directly focus on how to improve human’s study and education [2] In 1990th, some researchers (Brown, 1992; Collins, 1992) reconsidered the problems of orientation, think-ing and methods, and then put forward the concept of “design-based research” [3] De-sign-based research aims at verifying and improving principle-and -pre-study-based education design through forming study process Design-based research use” improve by steps” to put initial design into reality to see its effectiveness, then improve application basing on the feedback of practice, till all the biases are fixed Hence, a more reliable and effective design is formed [4] Following this pattern of design-based research, we de-velop two sections of research work, as follows:
In prototype implementing section, we study requirement for online case study en-vironment of users by literature review, questionnaire statistics, and personal inter-views Based on the initial requirement, we design and implement a prototype system
of Web-based Case Assisted Study Environment, WebCASE Research work and results of prototype system implementation can be found in
In practice research section, we study the case study activities supported by Web-CASE prototype system, with the course “Industry System Introduction” provided by Professor Darong Lu as our reference In this paper, we mainly concern problems in four levels: first is the study environment, studying overall teaching effectiveness and main functions of WebCASE; second is learning object, studying how original cases developing in WebCASE systems; third is study process, how to organize case studies under the support by WebCASE; finally is study evaluation, how to generally and effectively evaluate students’ performance in case study activities
Research on WebCASE prototype system based case study activities in system ap-plying section is the emphasis of this paper, and we will introduce research and results
of system improvement section in another paper later
2 Learning Object Selection
“Industry System Introduction” is started as a basic course for the requirement of integration of High Education Courses, as a compulsory undergraduate course of College of Economy Management, and also an elective course for all engineering
Trang 4majors, this course aims at developing engineering diathesis and economy concept Teaching should be open, innovative, and encouraging students to study by them-selves and collaborate In 2005 summer, 2005 autumn, 2006 spring, 2006 summer and
2007 spring, teachers organize students with case study activities based on WebCASE and student-summer social practice activities in collaborate study mode Basic prac-tice mode is Web-Enhanced Instruction, i.e., teachers are still organizing normal classes, and case resources and online study environment are used to help students finish study load to enhance the study effectiveness of this course
In order to be in line with research progress, we select “Industry System Introduc-tion” in 2007 Spring Semester as research area, and take case study activities supported by WebCASE as learning Objects 22 undergraduates from different de-partments and grades are enrolled in this course, and 10 cases are given to students at the beginning of the semester, as shown in Table 1

Above ten cases are related with ten major industries in Civil Economy, students are required to select cases and group according to their interests, and they need to submit a case analysis report at the end of semester, one report each group At last, C1, C2, C3, C5 and C8 are chosen by students, 10 of them select C1, 3 of them select

C2, 4 of them select C3, 3 of them select C5, and 2 of them select C8 Considering the capacity of each group, students who select C1 are divided into two sub groups, five students each group So finally, 6 groups (G1-G6) are formed up This paper takes the case study activities of these 6 groups as learning Objects Their Group IDs, numbers
of students, selected cases, and case analysis reports are listed in Table 2
3 Research Plan and Implementation
To solve the problems of study environment, learning Object, study activity and study evaluation in case study activities, we have done researches in 4 following sections Scene Observing Section During the semester of 2007 Spring, we have been par-ticipated the course as teaching assistant of “Industry System Introduction”, and we also maintain the WebCASE system as a system administrator We can observe pro-gress and result of each group either online or offline
Evaluation Design Section At the end semester, we design the case study activity rubric for course “Industry System Introduction” so that teachers can evaluate stu-dents, group members can evaluate each other, and students can evaluate themselves After the first round of usage, we modified some of evaluation guide lines
Questionnaire Investigation Section Before the end of semester, we design the ques-tionnaire of “WebCASE usage”, and investigate 22 students from different majors who
