学生学习,理解四则运算法则、规律,是一个具体——抽象——具体的过程。因此在计算教学中应充分运用直观教具,借助充分的感知材料,让学生在惑知的基础上建立起清晰的表象。同时又要注意不让学生思维停留在具体直观上,及时抽象、概括,以促进学生逻辑思维的发展。 我在教“两位数加两位数”时,根据教材编排特点,注意引导学生逐步离开具体事物进行抽象思维,逐步提高思维能力。
Students learn to understand the four algorithms, laws, is a specific - abstract - specific process. Therefore, teaching in teaching should make full use of visual aids, with the help of a full range of perceptual materials, so that students on the basis of knowledge to create a clear image. At the same time, we should pay attention not to let the students stay in the concrete and intuitive thinking, timely abstraction, generalization, in order to promote the development of students' logical thinking. When I was teaching “Double-digit plus Double-digit”, according to the characteristics of textbook layout, I paid attention to guiding students to gradually leave the concrete things for abstract thinking and gradually improve their thinking ability.
