單車休閒參與度對國小學童簡單機械學習動機與概念成就之相關性
The Impact of Cycling Participation on Fifth Graders' Learning Motivation and Conceptual Achievement of the Simple Machines
摘要
本研究旨在探討單車休閒參與度對五年級學童簡單機械學習動機與概念成就之影響，並瞭解學童對簡單機械的迷思概念與來源。以問卷及訪談方式調查台北市某國小五年級207名學童。研究工具有單車休閒參與度問卷、簡單機械學習動機量表、簡單機械概念兩階層測驗及簡單機械半結構式問卷等。採因果比較研究法分析各問卷變項之相關性，並輔以質性晤談資料；學童單車休閒參與度問卷得分，分性別進行排序，以避免極端分數造成高低參與組之分組結果，並以排序之中位數作為高、低參與度組之分界，簡單機械學習動機量表與簡單機械二階層測驗問卷收回後，逐題分析，再以描述性統計、獨立樣本t檢定及單因子變異數分析法來分析各組學童對簡單機械的概念成就狀況。晤談全程使用錄音機錄下與學童的對話，晤談資料先進行編碼，以逐字稿方式呈現學童的晤談結果。研究發現單車休閒參與度高的學童對簡單機械具有較佳的學習動機及概念成就；學童常見之簡單機械迷思概念主要為單車握把與行進時之平衡、前齒盤與後齒盤的旋轉方向及頻率、施力與速度之轉換效能及單車移動的機械原理等十大項，而迷思概念來源主要為感官印象、日常用語、不當的推論及家人的影響四個因素。

The purposes of this study were to investigate the different cycling participation of the fifth graders on (1)the differences between the learning motivation of simple machines; (2) the differences between the conceptual achievement of simple machines; (3) to investigate the types and sources of misconceptions of simple machines. The researchers used causal comparative research method, and selected the quantity-based paper-pencil test and semi-structured interviews to supplement qualitative data. The participants were 207 fifth graders from eight classes in Taipei City. There were three instruments including ”Cycling Participation Questionnaire(CPQ)”, ”Simple Mechanical Learning Motivation Scale (SMLMS)”, and ”Two-tier Diagnostic Instrument of Misconceptions about Simple Machines (TDIMSM)”.In the first phase of this study, participants were divided into three groups according to the results of CPQ. In the second stage, three groups were to investigate the relation of motivation and conceptual achievement with SMLMS and TDIMSM. In the final stage, eight students who had the different levels of CPQ were selected to explore the participants' ideas and misconceptions sources of simple machines. The collected data were analyzed by following statistical procedures: descriptive statistics, independent sample t-test and one-way ANOVA. The findings were as follows: (1) the participants who often engaged in cycling had higher learning motivation of simple machines; (2) the participants who had different cycling participation had different conceptual achievement of simple machines; (3) the participants' general misconceptions were the balance of handlebar and moving bicycles, the rotational direction and frequency reciprocated by crankset and freewheel, the efficiency of conversion of physical strength into velocity, and mechanics of cycling motion; furthermore, the main sources were the sensory impressions, everyday language and improper inference. The conceptions of simple machines are high-related with students' daily cycling experiences.
