在农村小学,恰当地使用自制教具,不仅能节约开支,还能解决教学仪器不足的问题。合理的开发、制作与使用自制教具对教师以及学生都产生着深刻的影响。《小学数学新课程标准》指出:“数学教学活动必须激发学生兴趣,调动学生积极性,引发学生思考;要注重培养学生良好的学习习惯、掌握有效的学习方法。学生学习应当是一个生动活泼的、主动地和富有个性的过程,除接受学习外,动手实践、自主探索与合作交流也是数学学习的重要方式,学生应当有足够的时间和空间经历观察、实验、猜测、验证、推理、计算、证明等活动过程。
In rural primary schools, the proper use of self-made teaching aids not only saves money, but also solves the problem of insufficient teaching apparatus. Rational development, production and use of self-made aids have a profound impact on teachers and students. The New Curriculum Standard for Primary Mathematics states: ”Mathematics teaching activities must stimulate students' interest, mobilize students' enthusiasm, trigger students' thinking, pay attention to cultivating students' good study habits and master effective learning methods." Students' learning should be a lively In addition to accepting learning, hands-on practice, self-exploration and cooperation and exchange are also important ways of learning mathematics. Students should have enough time and space to observe, experiment, guess, verify, reason, calculate, Prove activities such as process.
