正确认识相对应的关系,科学合理处理好以下一些关系,对于实施数学课程改革有重要意义,也有利于引导学生进行有效数学活动的过程,促进学生主动的发展。一、课堂教学要处理好“手段与目的”的关系多媒体信息量大,有扩展性,能向学生提供多种感官刺激,是教学的得力助手。可是如果我们以一堂课有没有多媒体为优劣的标准,那就走向极端了!使用多媒体课件,首先应该考虑该不该用,用在哪个环节上?其次要看是否符合教学的规律。如情境创设、演示验证的过程等,这些在多媒体上演示,可能不如学生动手操作、让学生感受过程来得真切,反而牺牲了许多宝贵的时间,使简单的问题 Correctly understanding the corresponding relationship and dealing with some of the following relations scientifically and reasonably is of great significance to the implementation of the mathematics curriculum reform, and also conducive to guiding students in the process of effective mathematical activities and promoting their active development. First, classroom teaching to deal with the “means and purpose” relationship Multimedia information is large, scalable, able to provide students with a variety of sensory stimulation, is teaching a handy assistant. However, if we have a class, there is no multimedia as a pros and cons of the standard, it goes to extreme! Using multimedia courseware, we should first consider should not be used in what link? Second, to see whether the law of instruction. Such as the situation creation, demonstration and verification process, which in the multimedia presentation, may not be as good as the students hands-on operation, let the students feel the process came true, but sacrificed a lot of valuable time, so that simple questions
