轻负高效是数学课堂教学改革的必然追求,要实现“轻负高效”的目标,必须提升初中学生自主学习的能力、打造智慧课堂、实施主体性教学。主体性教学以创设平等、民主、和谐的教学环境为前提,以数学知识为载体,师生主动参与、共同发展的一种新型数学教学观。 Light Negative Efficiency is the inevitable pursuit of mathematics classroom teaching reform. In order to achieve the goal of “Light Negative Efficiency”, we must enhance the ability of junior high school students to learn independently, build a smart classroom and implement subjective teaching. The teaching of subjectivity is based on the premise of creating an equal, democratic and harmonious teaching environment, taking mathematics knowledge as carrier, teachers and students take the initiative to participate in and develop together.
