| Summary: | 碩士 === 國立臺灣師範大學 === 工業教育研究所 === 88 === The purpose of this study was to investigate the instruction achievement of computer assisted instruction(CAI) on digital circuit skill instruction, with TINA, EWB and a self-developed multimedia system as skill instruction courseware.
The nonequivalent pretest-posttest design is used to test the effectiveness of two new CAI methods. Electronic Workbench (EWB) is a simulation training system, and Toolkit for Interactive Network Analysis (TINA) is a training system with additional test cards. Both of EWB and TINA systems were developed for digital circuit training. Thirty six students were selected from Taipei Municipal Sung-Shan Vocational Industrial-Agricultural School as experimental objects. They were divided into two groups. The experimental group used TINA system and the comparison group used EWB system for studying digital circuit skill. The achievement of knowledge and skill in both two groups were evaluated through the posttest. The retention test was given to the students three times week after week to check their learning condition.
The results of this research was summaried as the followings;
1.In knowledge studying, there is no significant difference between experimental group and comparison group；but in skill learning，there is significance between these two groups. The achievement of experimental group is higher than the comparison group. Therefore the effectiveness of EWB is no less than that of TINA in knowledge instruction, and the effectiveness of TINA is higher than that of EWB in skill learning.
2. The satisfaction of experimental group is higher than comparison group in courseware and environment design. The students preferred to study skill with both hands and brain.
3. In the retention of knowledge and skill abilities, there is no significant difference between experimental group and comparison group. But the average score of experimental group is higher than that of comparison group. Therefore the retention of learning system with both hands and brain is better than that of a pure simulation learning system on digital circuit skill instruction.
