摘要

本研究之目的係以學習者的認知腳本（簡稱腳本），透過認知取向的分析方式來探究學生對於從事科學學習活動的知覺。研究對象爲參與模組試教的彰化縣某國中九十二學年度35位國一班級學生。根據認知理論，學生對於學習活動事件的先前經驗，可以透過腳本予以呈現。研究者以自編且經專家審查之開放性問卷爲工具，教學前先調查個別的科學學習經驗，從篩選出的27份有效問卷蒐集到52項序列學習行動，按實徵研究的方法與建議，提取並排序當中行動項目頻率超過40%者，做成含有14項序列行動的班級學生群體腳本。教學實施後，透過「關鍵事例分析法」(CIT)的調查，同時參酌試教實況錄影與後續的深度晤談，進行此等相關的質性資料分析，以詮釋學生從事教學模組學習活動之經驗知覺。研究結果發現，學生的模組學習經驗共有六類知覺，當中有兩類對應於群體腳本，其餘四類違背群體腳本。研究顯示，透過腳本取向的方法能夠幫助研究者理解分析學生對於學習活動的觀點。本研究建議，教師在進行教學改變或模組研發過程時，對於學生原有的學習腳本應先進行調查與理解，這個道理與科學教學中的概念改變觀念非常相似。

The purpose of this study was to interpret student perceptions of learning through a cognitive approach, which was based on their cognitive scripts (i.e., script). Thirty-five 7(superscript th) grade students were selected to participate in this investigation. During this study, students engaged in a science module learning activity. According to cognitive theory, their scripts can represent prior experiences of science learning. Based on this theory, a sequence of 52 science learning actions were collected from these students by way of self-evaluation reports. Through script-elicit, the standard for selection was based on a level of action frequency that was higher than 40 percent. With regards to the comparison pair procedure, the researcher obtained the student-group script that contained 14 sequential actions. A qualitative analysis was conducted after the science module was completed, which included the student-group script, a critical incident technique (CIT), videotaped instruction, and personal interviews with students. From these sources, six categories of perceptions were found. Two categories corresponded to the student-group script. On the other hand, four other categories violated the student-group script. The result shows the significance of interrelating student views of learning activities with outside observers' through the script approach methodology. This research strongly suggests that teachers should more carefully investigate and understand the learners' script before changing their teaching practice or designing future teaching modules. The reason is quite similar to the notion of conceptual change in science teaching.
