优化课堂教学,提高教学效果,发挥教师的主导作用,体现学生的主体地位,将实践与理论有机结合,让学生在一种融洽的氛围中通过自主探索和合作交流的方式来学习数学,是优化教学的出发点和归宿点。实现这样一种教学模式,必须通过科学的课堂活动设计才能够实现。一、优化课堂教学的基本原则1、增加感性认识在教学中的份量,努力让学生融入教学过程这一教学理论层次以体验、观察、操作和感知为特点。以《梯形》教学为例,为了让学生切实把握住梯形的概念和 Optimize classroom teaching, improve teaching effectiveness, give play to the leading role of teachers, embody the dominant position of students, combine practice with theory, and enable students to learn math through self-exploration and cooperation and exchange in a harmonious atmosphere. Teaching the starting point and the final point. To achieve such a teaching model must be achieved through the design of scientific classroom activities. First, to optimize the basic principles of classroom teaching 1, increasing the amount of perceptual knowledge in teaching, and strive to enable students to integrate into the teaching process of teaching theory level to experience, observation, operation and perception as the feature. To “trapezoid” teaching, for example, in order to allow students to effectively grasp the concept and trapezoidal
