小学生的思维特点是以形象思维为主,而数学的重要特点之一就是其抽象性。因此,在数学教学中,如何培养学生思维能力,将抽象的数学知识寓于生动的形象之中,实现从形象思维到抽象思维的合理过渡,是我们所要研究的重要教学课题之一。随着电教多媒体走进课堂,使课堂教学无论从色彩、形象、声音等方面都向前迈进了一步。多媒体是能融形、声、光、色为一体的理想的教学手段。它能 The thinking characteristic of pupils is mainly based on image thinking. One of the important characteristics of mathematics is its abstractness. Therefore, in mathematics teaching, it is one of the important teaching topics that we should study how to cultivate students’ thinking ability, to abstract the mathematical knowledge in the vivid image and realize the reasonable transition from the image thinking to the abstract thinking. With audio-visual multimedia into the classroom, so that classroom teaching from the color, image, sound and so on are a step forward. Multimedia is the ideal teaching method that integrates music, sound, light and color. It can
