化学前概念对初三学生化学学习影响的研究

摘要初三学生在学习化学课程之前就已通过小学阶段的科学课程获得一些化学前概念，因此本文研究的是学生在开始学习初三化学课程之前就已经拥有的那些化学前概念以及这些前概念对初中化学学习的影响程度。本文首先深入研究了本地教材苏教版小学科学和上教版初三化学，发现两者在溶解现象、白色污染、酒精灯的使用注意事项、天然材料、二氧化碳的灭火性这几部分具有很大的联系。然后，笔者详细研究了两者在这六部分概念的相似点和差异点，最后根据以上的成果设计了一份学生可能用自身的前概念完成的调查问卷，通过对调查问卷数据分析和对其中回答具有代表性的学生的访谈，得到学生多是通过使用小学阶段所获得的化学前概念来回答这些问题的结论。由此本研究认为，学生从小学人文科学中获得的前概念对于中学化学学习有很大的影响。50995

Effect of Chemistry Preconception of junior high school students to learn chemistry

Abstract

Before junior high school students to study chemistry courses had to get some chemistry preconception through primary school science curriculum, this paper aims to study the concept of chemical precursors to those students in ju-nior high school before studying chemistry courses already have and these co-ncepts before learning of junior middle school chemistry influence level. Firstl-y,in-depth study of the local primary school science textbooks for Jiangsu Edu-cation Press and the junior high school chemistry, found both in the dissoluti-on phenomenon, white pollution, use of alcohol lamp precautions, natural mate-rials, carbon dioxide extinguishing of these parts has great contact. Then, the author studied in detail both the similarities and differences in this six-part co-ncept, according to the final results of the above design a student may use th-eir own preconceptions completed questionnaire by questionnaire data analysis and which answer representative student interviews give students mostly throug-h the use of chemical pre-primary level concepts obtained conclusions to ans-wer these questions. Thus the present study suggests that preconceptions of stu-dents from elementary school in the humanities have a great impact on high school chemistry learning.
