以CAL探究大一學生學習三用電表統整過程技能之研究

A Research on Learning Integrated Science Process Skills of Multitester with CAL

摘要


本研究主要在嘗試以電腦輔助學習(CAL)來探究大一學生進行三用電表統整過程技能的學習及解題歷程,其中透過電腦程式的設計及教材腳本的編製,以超媒體及情境學習理論為基礎來呈現電腦課程的內容。而後分析研究過程中所收集之學生學習及解題資料,以探討不同三用電表先前知識的學生,於學習本教材軟體的過程中,是否產生不同的學習型態,並歸納其錯誤型態:最後以實作測試的方式來了解學生學習本CAL軟體之學習成效。 基於行政與課程的考量,本研究選取高雄師大物理系一年級的學生為研究對象;然後依據本研究之「選取樣本調查問卷」,以選取適當的研究樣本。由問卷中選出符合本研究需求的樣本學生共10名,包括預試樣本2名、正式樣本8名。預式完成後,進行正式施測。每次分別由一名學生進行施測。 正式施測包括三個階段:先進行標準化開放式晤談,以了解學生對於三用電表的先前知識。而後開始教材軟體學習,學生於學習過程中,除了可由電腦自行記錄學習路徑及操作時間外,並採全程錄影、錄音的方式配合蒐集資料。最後一階段為實作測式,測試過程中,受試者並需實際操作三用電表來完成解題,由此了解受試者之學習成效。由8位學習者之學習及解題過程的資料本研究有以下的發現: (1)8位學習者學習本CAL教材軟體的過程中,可分成三種不同的學習型態:整體理解型、瀏覽理解型和依序操作型。(2)8位學習者於解題過程中,所出現的錯誤型態可分成兩大類:三用電表測量技能之錯誤型態與三用電表相關電學概念之錯誤型態。 (一).學習者在電學領域的知識基模,會影響其學習三用電表統整過程技能的學習型態。 (二).學習者利用本教材軟體進行三用電表統整過程技能的學習時,常出現的錯誤型態多導因於無法將抽象的電學知識與實際電路情境相結合,故教師於教導三用電表知識時,應特別注意此一方面。 (三).本教材腳本設計的特點,加上Hypertext的電腦軟體特色,將之融入三用電表統整過程技能的教學中,確實能使學生達成三用電表統整過程技能學習的目標。

The main objective of this research is to put CAL into a simulated usage of Multitester for studying the learning process of science integrated skills. A courseware, based upon the situated learning theory, for instruction hypermedia is designed to carry out this program. 10 subjects are randomly adopted from freshman physics students of National Kaohsiung Normal University. Two of them are for pretest, the others for formal testing individually. The learning process were recorded down with computer and videotape through the whole period of testing. Three patterns of learning style and two kinds of misconception are derived under data processing and analyzing. Three patterns of learning style are: (1) whole comprehensive learning, (2) glanced comprehensive learning, (3) serial operational learning. Two kinds of misconception are: (1) Multitester operational skills, (2) Multitester electric cognitive concept. Three conclusions are found as follows: 1. The electric knowledge schema of learner will effect his learning style of integrated science process skills in Multitester. 2. The electric misconception are due to the reason that students couldn’t bring electric theory into practice for an electric circuit. 3. The courseware, developed in this study, surely assists students to achieve the objective of learning integrated science process skills of Mutitester.
