“提问”在数学课堂中占有非常重要的位置,是组织教学的重要手段,是师生互动交流、沟通对话的主要渠道。好的课堂提问具有增进师生交流、激发学习兴趣、启迪学生思维、锻炼学生表达能力等功能。所以,提出有效的问题是增强数学课堂有效性的重要保证。一、课堂提问的设计l.围绕“关键点”设问。所谓关键点,是指教材的重点和难点,在教材的重点处提问,重点就会突出,在教材的难点处提问,难点就容易突破。如在“圆面积计算”教学中,圆面积计算公式的推导 “Questioning ” occupies a very important position in the math classroom, is an important means of organizing teaching, is the main channel for teachers and students to interact and communicate and communicate. Good classroom questions to enhance teachers and students to communicate, stimulate interest in learning, enlighten students thinking, exercise students’ ability to express and so on. Therefore, putting forward effective problems is an important guarantee to enhance the effectiveness of mathematics classroom. First, the design of classroom questions l. Around the “key points” set asked. The so-called key points, is the focus of teaching materials and difficulties in the teaching materials at the key questions, the key will be highlighted in the difficult teaching materials at the question, the difficulty is easy to break. As in the “circle area calculation ” teaching, the derivation of circular area calculation formula
