初中科目较多,学生的学业较重,学习兴趣容易淡化。重塑学生的学习兴趣,建立高效课堂,应该成为教师的首要任务。对于逻辑性较强的数学学科,抓住学生注意力引领学生思考是教学的重中之重。通常,在我们讲到相对简单易懂的内容时,学生会出现注意力不集中或者窃窃私语等情况,而在讲到理论性较强的内容时,学生则常常处于迷离状态。很多教师在课上发现此种状况时,都会声色俱厉地用恐吓或者训斥的方法强迫学生集中注意力认真听课,也许这种方法会奏效,但是久而久之会加重学生的厌烦感以及 There are more junior high school subjects, heavier students' study and easy to learn interest. Remodeling students' interest in learning and establishing an effective classroom should be the primary task of teachers. For the more logical maths, it is the most important teaching to grasp students 'attention to lead students' thinking. Often, when we talk about relatively straightforward content, students tend to be distracted or whispered, and students are often confused about the more theoretical content. Many teachers, when they find such a situation in their class, will use a threatening or reproachful method to compel students to concentrate their attention on listening carefully. However, this method may work, but as time passes, it will aggravate students'
