中学生化学学习困难的成因及其对策

On the cause of the difficulty learning chemistry of high-school students and its solving strategies

化学认知结构的缺陷是中学生化学学习困难的主要原因．通过指导学生内化化学知识、优化化学认知结构，帮助学生掌握思维方法、优化思维品质，以及通过换位教学、优化教学过程，可以帮助学生克服化学学习困难．

the deficiency in the chemical cognitive structure of the high-school students is the main cause leading to the difficulty learning chemistry. In order to overcome the difficulty, it is important to instruct the students to internalize chemical knowledge and optimize their chemical cognitive structure, also important to help them grasp the thinking method and improve their thinking quali- ty, and to optimize teaching process.
