一、认知激发教师要让学生认识到学习化学的重要性。近些年来,学生学习化学的兴趣已经下降到最低点。化学需要背的知识太多,有些地方实验跟不上,不了解学习化学的用途和意义。针对这种情况,教师应在化学教学中提倡化学知识的实际应用,让学生知道化学的作用。如以“原子——分子论”为主线,讲合成化学的发展,新材料的开发与化学的关系,以及化学材料对人类进步、社会发展的影响等内容,把化学科学的进步与人类物质文明、精神文明的关系讲明,
I. Cognitive Arousal The teacher needs to make students recognize the importance of learning chemistry. In recent years, students’ interest in learning chemistry has dropped to the lowest point. There is too much knowledge about chemistry, and experiments cannot keep up in some places, and they do not understand the purpose and significance of learning chemistry. In view of this situation, teachers should promote the practical application of chemical knowledge in chemistry teaching and let students know the role of chemistry. For example, taking “atom-molecular theory” as the main line, we talk about the development of synthetic chemistry, the relationship between the development of new materials and chemistry, and the influence of chemical materials on human progress and social development, and the progress of chemical science and humanity. The relationship between material civilization and spiritual civilization is clearly stated.
