投影以其形象直观,表现形式多种多样的特点,对学生具有很大的吸引力,容易激发学生学习的兴趣,帮助学生理解教材。在一年级的数学教学中,投影媒体更显示出其独特的作用。一年级学生好动,注意力不能持久保持,又是以具体思维为主,因此凡是生动的、具体形象的、形式新颖的、色彩鲜艳的投影图像,就容易引起学生的兴趣,吸引他们的注意;在学习过程中有具体的形象来支持,他们就容易懂。下面说说运用投影媒体在一年级数学应用题教学中的一些做法。一、运用投影进行应用题启蒙教学。六七岁的儿童,主要依靠事物的具体形象的联想来进行思维。运用投影提供特定图像,让学 Projection with its intuitive image, the performance of a variety of features, is very attractive to students, easy to stimulate interest in student learning to help students understand the textbook. In the first year of mathematics teaching, the projection media has even shown its unique role. First-year students are active, attention can not be sustained, but also based on specific thinking, so any vivid, specific image, the form of novel, colorful projection images, it is easy to arouse the interest of students to attract their attention ; In the learning process to have a specific image to support, they are easy to understand. Here to talk about the use of projection media in the first grade maths teaching some of the practices. First, the use of projection application questions Enlightenment teaching. Six or seven-year-old children, mainly rely on the specific image of things to think thinking. Use projection to provide specific images for learning
