进入小学中高年级后,学生开始系统地学习立体几何知识,由于学生年龄较小,空间观念较差,因此对这部分内容往往感到难度较大而缺乏学习兴趣。为了摆脱这种困境,创造良好的学习氛围,教师就要利用和创造各种条件引导学生通过对物体、模型等的观察;通过动手测量、拼摆、画图、制作、实验等活动,引发学生的学习兴趣,从而使学生对教学内容的无意注意转化为有意注意,始终在一种轻松愉快的气氛中学习,以利于学生掌握基础知识,形成初
After entering the upper middle school of primary school, students begin to systematically learn the knowledge of solid geometry. Due to their younger age and poor spatial perception, students often find it difficult to learn this part of their content. In order to get out of this predicament and create a good atmosphere for learning, teachers should make use of and create various conditions to guide students to observe objects and models through activities such as hands-on measurement, quasi-pendulum, drawing, making and experiment, Interest in learning, so that students unintentional attention to teaching content into intentional attention, always in a relaxed and happy atmosphere to learn, in order to facilitate students to master the basics, the formation of early
