摘要
以"电解质"概念为切入口,对河北省某普通中学的241名高一学生进行调查研究,并对部分化学教师进行访谈。结果表明:(1)不同类别学生在概念学习时的困难表征不同,体现在学困生知识储备匮乏、中等生知识应用能力较弱、优秀生概念理解深度不足;(2)相关概念之间具有很强的关联性,学生概念系统构建不够准确全面。基于3类学生的不同症结,给予相应教学策略,即重视学生的前概念与先前知识,提高知识储备;加强概念之间的深度关联,促进概念间转化;关注概念的发展历程,提升概念理解的深度。
This paper takes the concept of"electrolyte"as key point and conducts an empirical study on 241 students in an ordinary high school of Hebei province.The results show that:(1)The different types of students have different problems in the concept learning,(2)there is a strong correlation between the relevant concepts,and the construction of the student concept system is not accurate and comprehensive.Based on this,the corresponding strategies are put forward,such as the emphasis on the concept of students’ previous concepts and previous knowledge,the deep association between the different chemical concepts in order to improve conceptual transformation and pay attention to the development of concept to improve the depth of concept understanding.
