چکیده
This study reported the research ®ndings on improving programming skills of novice programmers by way of debugging practices. There were two objectives of the debugging training: (1) to uncover and to correct any misconceptions of the programmers; and (2) to improve the debugging abilities of the programmers. To meet these objectives, a model of debugging practices, DebugIt, was presented. The proposed model called for supervised debugging practices on short programs involving frequently committed programming errors. A system, DebugIt:Loop, was developed speci®cally for debugging practices on programs with loop related errors. Two sets of experiments were conducted with 26 college students and 46 senior high school students enrolled in introductory Pascal courses. For each experiment, students were randomly assigned into the experimental group (using DebugIt:loop for debugging practice) and the control group (using traditional programming practices). A posttest was administered to compare the debugging and errorless programming abilities among the students in the two groups. The statistical procedure of an ANCOVA was used to analyze the gathered data. The results showed that this model of supervised debugging practices was eective in improving novice programmers' programming skills. # 1999 Elsevier Science Ltd. All rights reserved.

A testing-based diagnosing system is implemented. The system has a problem library that collects some suitable problems and associated answers. The answers of each problem are related to misconceptions. Problem selector in the system provides some problems to test student. Based on the student's answers, the diagnoser in the system will discriminate the student's misconceptions. The problem sel...

This paper presents Bigger Bits, an interactive multimedia learning environment that teaches students about VLSI within the context of computer electronics. The system was built with COSMOS (Content Oriented Semantic Modelling Overlay Scheme), which is a modelling scheme that we developed for enabling the semantic content of multimedia to be used within interactive systems.
