中文摘要 | 本研究的主要目的,是要從解題約角度,設計一套結構嚴謹、包含操作 性問題與開放式說明理由問題之二段式紙筆測驗,以探查學生對簡單直流電路的 完整概念結構,再進一步分析學生直流電路概念結構的類型,並且探究學生運用 那些核心概念或邊際概念於簡單直流電路的解題。研究樣本為自中部地區一所高 中之三個班級所隨機抽樣而得的24名學生。學生在做完紙筆測驗後,再接受個別 晤談。 研究結果發現:學生對直流電路的概念結構可以分成三大類型:電池提供固定電壓 型、電池提供固定電流型、電池提供固定電壓電流混合型。電池提供固定電壓型 又可分成五個類別:1)電壓功率型; 2)誤用公式型;3)電壓耗損型:4)分配電壓型:5) 電阻阻擋電流型。電池提供固定電流型又可分成兩個類別:1)電流平分型;2)電流分 支型。電池提供固定電壓電流混合型又可分成三個類別;1)簡單電路型;2)電流耗損 型;3)固定電壓型。除了電壓電流混合型中少數的學生之外,大部份學生對直流電 路之概念結構都具有非常高的完整性(integrity)。換句話說,這些學生們固定用某 些概念來解決所有直流電路的問題,其中有些是正確的概念,有些則是錯誤的迷 思概念。 |
英文摘要 | In order to investigate students' conceptual structures concerning simpleDC circuits, a paper-pencil, two-tier test which consists of operational questionsand open questions for students to explain their reasoning, was developed.Twenty-four high school students from central Taiwan area participated in thisstudy. After taking the written test, each student was interviewed individually.Students' responses were analyzed to determine their major conceptions andconceptual structures regarding DC circuits. Results of this study include: 1) Most students answer all the DC circuit questions in the test with a number of concepts which form conceptual structure with very good integrity; 2) Three types of conceptual structure regardingDC circuits have been identified, each can be divided into several sub-types. 3)Only 2 of the 24 students use the model of current comsumption to solve DCcircuit problems, while other students who also answer that bulbs in serial shinewith deffernt brightness use voltage comsumption model or bulb-slow-down-current modelto solve D.C. Circuit problems. |
