高中化学中迷思概念的研究——以物质结构和性质部分为例.docx

摘 要
我们在多年的教学中形成化学概念教学模式固然使教学遵循了认识的一般规律,但不少地方忽视了化学概念及其教学的独特性和内在规律。近年有人对高三学生作过的调查显示:%的学生认为化学概念在中学化学中所占的地位重
要,%的学生觉得学****化学基本概念、基本理论最困难, ,%的学生认为影响化学科学概念掌握的主要因素来自头脑中已经存在的一些相异构想的干扰。在苏教版《物质结构与性质》教材投入使用后,教材的内容和难度与以前相比都有较大的改变,学生学****下来概念的掌握情况如何,存在怎样的迷思概念?
本论文是在广泛分析、借鉴国内外在哲学、心理学以及教育科学方面的研究成果基础上,结合化学学科教学实际进行的一个尝试:探查学生有关物质结构和性质概念的现状,探索促进学生概念转变的教学策略。作者试图通过问卷测试和个别访谈相结合的方法诊断高中学生在某些概念理解上存在的困难,归纳各学生理解的情况,分析产生困难的原因,并对概念教学提出建议,为化学教学改革做一些基础性的工作。

Abstract
眙have formed the teaching mode of conceptions in chemis血T in the last few year,but we often overlook the conception itself and廿le distinctiveness and inner roles in survey in recent years about serfior three students showed % of the students believed that conceptions in chemistry learning in senior higll school was important,and %regard the learning of basic conceptions and theories as the most %of the students tllink that the main element influencing the
master of conceptions is the thoughts that have already existed in our the

Based on the analysis of the achievements Oli philosophy,psychology and educational science at home and research work bining the teaching practice of chemistry:to check how well the students have mastered the conceptions of the s仃ucture and nature of objects and tO search for the teaching strategy of students’conceptual author tries to see the di伍curies in understanding those conceptions,generalize how well they understand them,analyze the reason for these di伍curies and give some suggestiOIlS on this topic。so as to do some basic work for the teaching revolution.
