中文摘要 | 本研究旨在探討教師使用電腦自製的視聽媒體進行教學對學生學習成 就之影響。以國小自然科第十一冊 「族群與群落」單元為實驗教材製作教學投 影片,進行實驗研究。教學媒體由六位隨機從彰化市區公立小學選取之高年級自 然科任教師,根據單元目標共同運用電腦發展。單元評量工具的發展,也是由六 位老師共同發展,經兩度預試,分析試題之難度、鑑別度,並修改後完成內部均 質性信度為 0.83的試卷一份,供實驗研究前、後及長程測驗用。為評估學生對 透明投影片教學接受程度,易使用情意調查問卷收集實驗組學生對教學法的意 見。實驗教學學生樣本由六位教師所任教之小學六年級中隨機抽取兩班,隨意指 派一篇實驗組,一篇控制組,實驗組接受媒體教學,控制組則由同一位教師使用 傳統口授法教學,同時進行兩週教學,並收集前、後及長程測驗成績,進行統計 分析。結果顯示,視聽媒體教學法確實在組間造成後測及長程測驗成績的顯著差 異,學生性別因素則未在學習成就上表現差異。實驗組學生後測及長程測驗成績 與學生學業總成績及自然科成績都有顯著相關(P<0.01)。學生對媒體教學法的接 受程度經電腦量化後指出,學生願意繼續使用本教學法學習,認為本教學方法可 以增進學習效果。 |
英文摘要 | The purpose of this study was to examine the effectivenessof computerized audio-visual media adopted in science teaching inelementary schools. For this purpose, six science teachers wererandomly selected from six elementary schools in Changhua City,Taiwan, R. 0. C. The teachers were responsible for transparencydevelopments, evaluation instruments, aptitude questionnaires,and media instructions. From their schools each teacher randomlyselected two classes as samples. Their were, 584 students, twelveclasses, in two group. Each group was pretested first. Then thetwo groups were taught an identical unit of study. In theexperimental group, the transparencies were adopted, while in thecontrol group, only conventional instructions were given. At theend of a two-week study, both groups were post- tested, .six weeksafter the post-test, a long-term memory test was held. Based uponthe following data: sex, academic achievements, scienceachievements, pretest scores, post-test scores) long-term memorytest scores, and questionnaire responses, the statistics obtainedfrom ANOVA and pearson correlation demonstrated seven out of eightsets of variables as significantly .showed students' exact positiveattitude toward the media. Accordingly, the media had positiveeffectiveness upon science teaching; therefore, the media isrecommended in science teaching in e-lementary schools. |
