高中化学涉及的知识系统性较强,知识点繁多且枯燥。因此教师优化课堂组织设计,提高课堂教学效率,对于提高学生学习化学的积极性和化学素养有非同寻常的意义。笔者从课堂教学的两个方面,即导入新课和提问,对它们的功能和方法进行探讨。1.导入新课的功能及方法导入新课在中学化学课堂教学中是一个重要的环节。新颖别致的导课,必然会先声夺人,对学生产生强大的吸引力,使课堂教学氛围立即活跃起来。新课导入要与教材内容和学生特点相适应,对学生接受新内容有启发性,以便学生实现知识的迁移。1.1新课导入功能导入新课通过对旧知识的复习和重组,使之形成适合于
The chemistry involved in high school chemistry is systematic, knowledgeable and boring. Therefore, teachers to optimize classroom design, improve classroom teaching efficiency, to improve students’ enthusiasm and chemistry of learning chemistry have extraordinary significance. The author from two aspects of classroom teaching, that is, the introduction of new courses and questions, to explore their functions and methods. 1. Introduction of new lesson features and methods into the new lesson in the middle school chemistry classroom teaching is an important part. Novel and choreographed lesson, will inevitably take the lead, has a strong appeal to students, the classroom teaching atmosphere immediately active. The introduction of the new curriculum should be compatible with the content of the teaching materials and the characteristics of the students, and inspire the students to accept the new content so that the students can realize the transfer of knowledge. 1.1 New Course Import Function Import New Course Through the review and reorganization of old knowledge,
