在小学数学课堂教学中,课堂教学时间是有限的,而数学知识却是无限的,要想使学生在有限的时间内学到无限的知识,除了选择好教学内容以外,教师还要把握好精讲的原则,以精讲促高效,从而为全面提升学生数学学习效果服务。那么,在小数课堂教学中,关于精讲方面需要注意哪些原则要求呢?一、精讲要具有针对性数学是一门逻辑性比较强的学科,并且还具有一定的系统性。这是因为旧知是学生学习新知的基础,新知又是旧知的延续与发展。因此,在数学课堂教学中,教
In primary school mathematics classroom teaching, classroom teaching time is limited, and mathematical knowledge is unlimited, in order to enable students to learn unlimited knowledge within a limited period of time, in addition to choose a good teaching content, teachers also need to grasp the fine The principle of speaking, to promote the efficient use of efficiency, so as to enhance the effectiveness of student learning mathematics services. So, in the decimal classroom teaching, what principles should be paid attention to in terms of exquisite speeches? First, exquisitely speaking, to have targeted mathematics is a relatively logical discipline, and also has a certain degree of systematicness. This is because the old knowledge is the basis for students to learn new knowledge, new knowledge is the continuation and development of the old knowledge. Therefore, in mathematics classroom teaching, teaching
