Introduction Prediction methodology & Recommendation
Process Results & Evaluation Proposed Future Research
introduction
Focus on relation between course categories and student’s preferences Preference: Mandatory courses should not be taken into
consideration when analyzing students preference Category: Classify courses>>Each course covers more
than one category>>weigh coursesFuzzy: AI(90%),Research(85%),Math(70%)Neural Networks: AI(90%),Research(85%),Math(70%)Ken: Fuzzy and Neural Networks
Objective: construct a web-based course recommendation system that only depends on the courses chosen by students
Prediction methodology
Datamining technique:
Apriori algorism (Agrawal & Srikant, 1994)
Recommendation process
Classifying courses/designing weights
Collecting Students’ Course Selection Records
Make Suggestions to Student
Construct Important Orders of Categories
Merge Rules into A Preference Sequence
Results and Evaluation
4 consecutive terms, senior college students Class 2001: 127 students’ course selection
record, 34/83 questionnaires response Class 2002: 102, 100% response rate 6 categories: research, theory, math,
hardware, software, network (information science)
Accuracy rate for preference sequence
General assumption: 4th term should have the highest accuracy rate
Explanation: fewer prerequisites, more electives, tend to follow graduate school guidance
Class 2002: target 13 students who plan to go to graduate school straight after college
Proposed Future Research
Student’s needs change analysis How to find course categories classified by
students? What are the relations among courses in student’s mind?
Time series analysis Is it possible to develop or plan a series of
courses depends on the student’s major interests?
