初中学生在开始学习化学知识时,出于对新学科的兴趣和受到“新鲜热闹”的化学实验的吸引,往往学习热情高涨,但在新教材第四单元“物质的构成”、第九单元“溶液”以及第十、十一单元成为初中化学学习的三个重大分化点后,学生逐渐出现学习思维障碍。主要从化学思维障碍的主要表现形式及分析、克服思维障碍的对策两方面进行了分析和阐述。 When junior high school students begin to learn chemical knowledge, they tend to be enthusiastic about learning because of their interest in new subjects and the chemistry experiment of “freshness and excitement.” However, in the fourth unit of the new textbook, “Constitution of Matter” After the ninth unit “solution ” and the tenth and eleventh units became the three major points of differentiation in junior high school chemistry, students gradually developed learning disabilities. Mainly from the main manifestations of chemical thinking disorders and analysis, to overcome the obstacles to thinking two aspects of analysis and elaboration.
