摘要

本研究旨在探討使用電腦輔助教學(CAI)，於數位電路技術教學之應用成效，以TINA、EWB及自行開發的多媒體光碟系統作為技術實習之教材。
本研究主要為教學實驗，以臺北市立松山工農電子科學生為實習對象，採用準實驗設計(quasi-experimental design)之「不等的前測–後測設計」(nonequivalent pretest-posttest design)。實驗組採用「TINA互動式電路分析系統」，簡稱為「TINA」；對照組採用「Electronics Workbench電子工作檯系統」，簡稱為「EWB」。實驗教材並採用自行開發的一套多媒體光碟「電腦輔助數位電子技能學習系統」，分成TINA版及EWB版，即兩組均接受數週CAI之數位電子實習，並持續三週作學後保留度的評量。主要差異在於EWB為純模擬之CAI電子電路軟體；而TINA不僅有虛擬儀表可做模擬分析，更有硬體設備連線，讓學習者能接觸實物操作。本研究即針對兩組CAI教學實驗作驗證性比較。
經過半年開發教材，與半年實驗教學，本研究之主要結論如下：
一、學後成效方面：實驗組的成績在認知評量未顯著高於對照組，而技能評量有顯著高於對照組。證明在認知部份兩組成效相當，但在技能部份TINA對技術教學比EWB佳。
二、學習滿意度方面：實驗組的學習滿意度平均高於對照組，且有三項向度呈現顯著。可見手腦並用的學習系統較受學生青睞。
三、學後保留度方面：實驗組的成績在認知保留度及技能保留度未顯著高於對照組，不過實驗組的平均值在認知、技能保留度評量均高於對照組。可見手腦並用的學習系統的學後保留度較純軟體模擬的系統為高。
關鍵詞：電腦輔助教學、TINA、EWB、數位電路技術、學後保留度。

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.
Keywords: computer assisted instruction(CAI), TINA, EWB, digital circuit learning, retention.
