agenda l l Introduction Prediction methodology & Recommendation Process Results & Evaluation Proposed Future Research

introduction l Focus on relation between course categories and student’s preferences l l l Preference: Mandatory courses should not be taken into consideration when analyzing students preference Category: Classify courses>>Each course covers more than one category>>weigh courses Fuzzy: 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 l Datamining technique: Apriori algorism (Agrawal & Srikant, 1994)

Recommendation process Classifying courses/designing weights Collecting Students’ Course Selection Records Construct Important Orders of Categories Merge Rules into A Preference Sequence Make Suggestions to Student

Results and Evaluation l l 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 l l l General assumption: 4 th 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 l l 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?
