学生是学习的主体,提高学生自主学习的能力是教育的目标。化学学科的独特之处在于从微观中看世界、从变化中看世界、在符号中理解世界、从实验中重现世界。化学课堂教学是一次丰富而生动的“理解”与“对话”的师生交往过程。将学生认知阶段与学科特征相结合,从生活中提取概念,从讨论中理解内容,在实验中加深理解,调动学生观察现象的兴趣,培养学生自主学习的能力,从而完成教学任务,进而提高教学效果。这是高中化学课堂教学方式的新探索。
Students are the main body of study. It is the goal of education to improve students’ ability to learn independently. The uniqueness of chemistry is that it looks at the world from the micro perspective, the world from the perspective of change, the understanding of the world through symbols, and the reproduction of the world from experiments. Chemistry classroom teaching is a rich and vivid process of interaction between teachers and students “understanding ” and “dialogue ”. The cognitive stage and the characteristics of the subject combine to extract concepts from life, from the discussion to understand the content, deepen understanding in the experiment, to mobilize students ’interest in observing the phenomenon, to develop students’ ability to learn independently, so as to complete the teaching task, and then improve Teaching effect. This is a new exploration of high school chemistry classroom teaching.
