以问题为中心的教学过程大致可以分为:提出问题、探究问题、深化问题三个环节。这三个环节中,提出问题实际是引入物理概念,学生从教师创设的情节中提出问题;探究问题实际是让学生在合作探究问题的过程中建立物理概念,使概念的生成更加顺利;深化问题的过程是让学生在学习中灵活理解、运用概念。以“向心力”教学为例,分析以问题为中心的教学模式具体的环节。一、提出问题,引入概念 The problem-centered teaching process can be roughly divided into three stages: asking questions, exploring questions and deepening questions. In these three aspects, putting forward the question is actually introducing the concept of physics, and asking questions from the plot created by the teacher. To explore the question is actually to let the students establish the concept of physics in the process of cooperation and exploration and make the concept generation more smoothly. The process is to enable students to understand and apply the concept of learning flexibly. Taking the teaching of “centripetal force” as an example, this paper analyzes the specific links of the problem - centered teaching mode. First, ask questions and introduce concepts
