数学知识固有的、内在的严密性和结构性,决定了它在传承中必然旧知识孕育着新知识,而新知识是旧知识的拓展和延续。数学学科的特性,有利于开展数学预习,让学生以有准备的状态参与学习,进而实施高起点的教学、提高课堂教学效率。更重要的是学生最终将要独自面对问题,而数学预习是培养学生自主探究能力、学会独立学习的有效方法。为此,我校开展了“课前预习、先学后教的数学课堂教学”的课题研究。
The intrinsic, rigorous and structural nature of mathematical knowledge determines that it must inherit necessarily new knowledge, which is the extension and continuation of old knowledge. The characteristics of maths are conducive to the preparation of maths, allowing students to participate in learning in a prepared state so as to implement high starting point teaching and improve the efficiency of classroom teaching. More importantly, students will eventually have to face the problem on their own, and mathematical preparation is an effective way to cultivate students’ ability of independent inquiry and learn to learn independently. To this end, our school conducted a “pre-class preview, teaching mathematics classroom teaching” research.
