「機械製造」課程運用多媒體教學對學生學業成就之影響

Abstract

本研究旨在探討電腦多媒體教學法應用於技高機械群「機械製造」課程，對於學生學業成就之影響。研究對象為技高一年級學生進行5週分組教學實驗。本研究採用準實驗研究法之「不等組前後測設計」，採用便利取樣叢集抽樣，分成實驗組與控制組。所得資料經獨立樣本t檢定、相依樣本t檢定、單因子共變數分析。研究結果如下，歸納以下結論： 一、接受教學策略的實驗組學生在「機械製造」課程學業成就測驗表現，經由共變數分析結果，有顯著差異；兩組比較的結果可知實驗組學生後測成績明顯優於控制組後測成績。 二、t考驗發現實驗組學生經實驗後，在「機械製造」課程學業成就表現有顯著差異，可見實施電腦多媒體教學對學生在「機械製造」課程學業成就表現有顯著進步。 三、接受教學策略的實驗組學生在學業成就認知、情意、技能表現，經由共變數分析結果，皆有顯著差異；由此知實施電腦多媒體教學有助於提昇學習效果。 四、t考驗發現實驗組學生經實驗後，在學業成就認知、情意、技能表現有顯著差異，由此知實施電腦多媒體教學，有助於提昇學生學習；而控制組學生在學業成就認知、情意表現未達顯著差異。

最後，根據本研究發現與結果，對學校教師、家長、職科學生及後續研究者，提出具體建議。

This study aimed to explore the effects of integrating Multimedia Instruction into Mechanical Manufacturing Course on students' academic achievement. The study was a quasi-experimental study with convenience sampling. The participants were first-grade students of a vocational senior high school. In the five-week study, the study subjects were divided into two groups, the experimental and the control group. Both groups took pre-tests and post-tests. The Independent-Sample T Test, Paired-Sample T Test, and One-Way ANOVA were employed to analyze the data. The major findings were summarized as follows: 1.There was a significant difference between the students’ academic achievement after the teacher adopted this teaching approach. The post-test scores of the experimental group were much better than the control group. 2.The data analysis of the T Tests reveled that the experimental group displayed significant difference between pre-test and post-test scores. Due to Multimedia Instruction, the experimental group made great progress in their academic achievement. 3.The data analysis of the One-Way ANOVA showed that the experimental group displayed significant difference in the Cognitive, Affective, and Psychomotor Domain. 4.The data analysis of the T Tests reveled that the experimental group displayed significant difference in the Cognitive, Affective, and Psychomotor Domain, but the control group didn’t. The findings can provide teachers, parents, and learners with guidelines in the use of the multimedia-teaching media.
