提高课堂教学的有效性,已成为小学数学教师的任务。“有效性”是教师和学生共同努力的结果。文中主要针对教师,提出了提高教学有效性的有力措施。提高备课有效性:正确把握教学内容和教材内容;深入了解学生,找准教学的起点;客观分析教材,把握每节课教学的重点、难点和关键;努力挖掘教材中蕴涵的数学思想方法。增强情境创设的有效性:情境要有明确目的、情境要有“数学味”、情境要有现实意义。强化学习过程的有效性:激发兴趣,诱发参与动机;适时点拨,指导参与方法;创设时空,保证参与机会。重视学习方式的有效性:不排斥接受学习,重视探究学习,注重教学的互动性。
Improving the effectiveness of classroom teaching has become the task of primary school mathematics teachers. “Validity ” is the result of joint efforts of teachers and students. The article mainly aimed at teachers, put forward to improve the effectiveness of teaching effective measures. Improve the effectiveness of lesson preparation: correctly grasp the contents of teaching and teaching materials; depth understanding of students, identify the starting point of teaching; objective analysis of teaching materials, grasp the key points, difficulties and key points of each lesson; and strive to explore teaching methods contained in mathematical thinking. To enhance the effectiveness of creating a situation: the situation must have a clear purpose, the situation must have a “mathematical taste”, the situation should have practical significance. Strengthen the effectiveness of the learning process: to stimulate interest, motivate the motivation to participate; timely dial, guide participation methods; create space-time to ensure participation opportunities. Emphasis on the effectiveness of learning: Do not exclude learning, emphasis on inquiry learning, pay attention to the teaching of interaction.
