Abstract

Reinforced Concrete (RC) design is a very important course on civil engineering in higher education. Students are taught in this course how to design a structure by using reinforced concrete. Students are also trained to follow the building code (Code by ACI, American Concrete Institute) into design 11. Because the building code is a very complicated collection of rules, students are easily misunderstanding in the learning procedures and instructors or tutors must pay more time to explain the RC theory and describe the procedures of design 8,9. Otherwise, teachers need spend a lot of time to correct students’ examinations5. It is also difficult to evaluate students’ misconceptions by traditional test. Therefore, it is necessary to develop computer-aided tools to help teachers’ teaching for the RC design course.

This paper describes AWRC, a web-based reinforced concrete design adaptive testing system developed by author’s research team. AWRC includes a test bank saves over 200 testing problems, a testing generator develops adaptive testing problems to each student’s achievement level, a diagnosis system may find students’ misconception through the testing progression. A level manager is used to calculate the difficulty level of a problem and the achievement level of a student. An algorithm by “skills” to assign the initial difficulty level of a problem is proposed in this paper. The functions of AWRC also include test delivery, scoring, and record keeping. AWRC can help teachers to generate, score and assess an examination. Students may login AWRC to practice examples and to check the design procedures of RC structures in 24 hours.

The testing system is made on the NT platform, written by ASP (IIS), Visual Basic and uses SQL Server as a database system. The major advantage of this testing system is fully automatic and adaptive.
