现代信息技术辅助教学能突破时间和空间的限制,生动形象地再现事物发生和发展的过程,在小学数学学科的抽象性和逻辑性与小学生思维的具体形象性之间架起桥梁,为提高课堂教学效率创设了条件。利用信息技术,创设教学情境、建立空间观念、化解重、难点,解决实际问题。 Modern information technology-assisted teaching can break through time and space constraints, vividly reproduce the occurrence and development of things in the elementary mathematics disciplines of abstract and logical and primary school students thinking of the concrete image of the bridge between the construction, in order to improve classroom teaching Efficiency creates conditions. The use of information technology, creating teaching situations, the establishment of space concept, resolve heavy and difficult to solve practical problems.
