笔者以新课程基本理念为依据,确立以生为本的教学原则,结合初中化学实验的特点,对构建三种新的课堂教学模式进行了探究。这主要体现在:一、先完成自主编制的学生实验活动手册,后指导学生动手做实验,充分发挥实验的作用;二、让学生体验知识的产生、发展、变化过程,培养学生实验探究意识,初步形成科学探究的能力;三、发掘日常生活和生产中的有用素材,让化学实验教学与实际相结合,增加学生实验探索的机会。
Based on the basic concepts of the new curriculum, the author establishes the teaching principle of taking students as the foundation, and explores the construction of three new classroom teaching modes based on the characteristics of junior high school chemistry experiments. This is mainly reflected in: First, to complete the self-compiled student experimental activity manual, after guiding the students to experiment, give full play to the role of the experiment; Second, let the students experience the emergence, development and change of knowledge, training students to explore the awareness, The initial formation of the ability of scientific inquiry; Third, to explore the daily life and production of useful materials, so that chemical experiment teaching and practice, increase the chances of experimental exploration.
