信息化是当今社会发展的一大趋势。信息技术的发展已经渗透到政治、经济、文化以及我们生活的方方面面。信息技术的发展给教育本身带来了巨大的冲击,新的教学媒体的出现,引起了教育模式的飞跃。在数学教学中,我们普通中学学生的数学素养与重点中学学生相比差距较大,特别是在空间思维能力方面。他们不能在头脑中很好地展现几何模型,再现事物的发生、发展过程。 Informationization is a major trend in today’s society. The development of information technology has penetrated politics, economy, culture and all aspects of our life. The development of information technology has brought a huge impact on education itself. The emergence of new teaching media has caused a leap in educational model. In mathematics teaching, the mathematics literacy of our ordinary middle school students is far behind that of the key middle school students, especially in terms of spatial thinking ability. They can not show the geometric model well in their minds to reproduce the occurrence and development of things.
