连续下乡镇小学听课调研,体会颇深。农村小学数学课堂教学在提高效率上存在着障碍,除了物质设备等“硬件”欠缺外,在教学思想和教学方法等“软件”上主要有如下几点不足。1.灌输式的教学思想。比如“角的认识”一课中,教师采取一讲到底的方法,首先讲述“线段”与“直线”的区别和联系,接着讲述“射线”的产生和实例,然后出示三角板、五角星、纸折扇等角,并给“角”下定义,指出角的各部分名称和符号表示方法,以及角大小的度量和它的计量单位,
Continuous under the town primary school research, experience quite deep. There are some obstacles to improve the efficiency of mathematics classroom teaching in rural primary schools. In addition to the lack of “hardware” such as physical equipment, there are mainly the following deficiencies in the “software” of teaching thoughts and teaching methods. 1. Instill teaching ideas. For example, in the lesson of “Cognition of the Corner”, the teacher takes a one-to-one approach: Firstly, it tells the difference and connection between “line segment ” and “straight line And then show the triangle, pentagram, paper folding fan angle, and to ”angle" under the definition, pointed out that the name of each part of the angle and symbolic representation, as well as the size of the angle measurement and its unit of measurement,
