中文摘要 | 國小數學課程沒有抽樣概念,但學生在生活中卻常有簡單隨機抽樣的經驗,因此本研究採問卷調查法,利用所設計的評量詴題,探究國小高年級學生從周遭訊息和生活經驗所建構的自發性抽樣概念雛形。評量詴題有四個面向:樣本、朮體、隨機、樣本代表性。研究對象為臺北地區國小高年級523位學生。結果發現,多數學生的表現受到生活經驗和語言的影響,學生傾向使用具體形物來描述樣本和朮體。多數學生無法解釋多項分配之隨機樣本和樣本代表性的意義,因而呈現迷思概念。 |
英文摘要 | Although the sampling concept is not introduced in elementary school mathematics curriculum, students often experience simple random sampling in their daily life. Therefore, we conducted a survey method and designed a questionnaire to explore the spontaneous sampling concepts of 5th and 6th graders from their daily life experiences and information. The questionnaire consist of four components , including sample, population, random, and sample representation. A total of 523 elementary school 5th and 6th graders from Taipei area participated in this research. The results showed that the performances of most students were influenced by their daily life experiences and language. Students tended to use concrete objects to describe sample and population. A relatively large number of students were unable to explain random samples from the multinomial distribution and significance of the sample representation, and therefore presented misconceptions. |
