问题是物理教学的核心,物理教学的过程应当是一个不断提出问题和解决问题的过程,教师无论是在教学的整体过程中,还是在教学的某些细微环节上,能否提出对学生具有挑战性和吸引力的问题并使学生产生问题意识,是进行自主学习的关键。本文结合“超重和失重”的教学案例,阐述了如何在物理教学过程中创设恰当的问题情景,引导学生自主的学习。 The problem is the core of physics teaching. The process of physics teaching should be a continuous process of raising questions and solving problems. Whether teachers can challenge students because of the whole process of teaching or some minor steps of teaching Sexual and attractive issues and make students produce a sense of problem is the key to self-learning. In this paper, combined with the teaching case of “overweight and weightlessness”, this article expounds how to create appropriate problem scenarios in the process of physics teaching and guide the students to study independently.
