中文摘要 | 本研究主要在探究學生在不同時間概念文字題的解題表現,以紙筆測驗並配合訪談為主要研究方法。自編測驗的設計是從「時間量、時刻」這個主題分兩部份進行研究,一部份是探究學生在不同時間概念下的解題表現,然後將時間用語分為數學用語及時間用語這兩種用語,分別探究學生在「過午」與「過日」這個「時刻跨越」的時間概念中「12時制」與「24時制」的概念;另一部份是透過另類試題分析學生在不同時間概念下的文字表現。 研究結果發現:在解題表現中,學生遇到跨越二日的題目會先找出一個共同的起始時刻,而涉及12時制且過午的時刻大都會先轉換成24時制,常利用起始量加上經過量等於結果量的向量想法去解不同結構變項的題目,也以預期的答案或關鍵字來決定時間文字題的運算符號,並傾向用大的時間量去減小的時間量這個常見的錯誤策略。 在文字表現中,學生認為×時×分就是指事件發生的時刻,會從題目中的運算符號來決定所寫問題的慣用字,並依據題目中數字出現的先後順序,來安排數學問題的文理脈絡。 |
英文摘要 | This study aims to analyze students' performances of solving different "Time Word Problems", This research through questionnaire, interview and investigation, to effectively define the types of time terms, and then a writing test of "Time Word Problem" is taken and an interview is used together to find how elementary students solve these problems, their types of strategies, and the common errors they make and the reason why they use certain kind of solution, The purpose of my research is to provide elementary teachers the reference of teaching the concept of time. The results of the research are as follows. In performance of solving problems when students solve the question of more than one day, they'll first find a common starting time and if the question related to 12-hour system and the time is exceed noon, they will transform it to 24-hour system. Students would often use the idea that initial amount plus processing amount equal to result amount to solve problems of different structure variables. Besides, the expected answer or keyword is also used to decide the type of mathematical calculation. Students often have a common error that is they tend to use a large amount of time to subtract a small amount of time. In the performance of writing, students consider that some hour some minute means the moment that an event happens, and they use the mathematical calculation to decide the consistently use they will write in a question. They according to the sequence of the number appearing in the problem to arrange the context of the mathematical problem. |
