中小学校每年进行的三小作品活动在当今素质教育中起着重要作用。通过一个个小小的设计方案,可以窥见中小学生的观察事物、分析事物和改造事物的能力。通过一些很简单的制作,可以发现他们心灵手巧的一面,也可以使他们从课本上所学的知识得到进一步的提高和巩固,使他们的思维更开阔、想象力更加丰富,避免出现高分低能的现象。如何引导学生进行三小作品的方案设计及成品制作,笔者经过几年的探索,总结出一些常用的思维方式。 一、顺向思维方式 这是从具体事物存在的本质出发,向纵深方向发展,以求得更完善的性能和更齐全的功能的思维方式。如当今的模拟电视信号接收系统,无论电路怎么改善,图象质量也很难再上一个台阶。只有通过把模拟信号改为数字信号,电视机由模拟接收改为数字接收,才能实现图象质量的提高。轿车
The three small work activities each year in primary and secondary schools play an important role in today’s quality education. Through a small design, you can see primary and secondary students observe things, analyze things and ability to transform things. Through some very simple productions, they can find out their dexterous side, and they can further enhance and consolidate what they have learned from the textbooks so as to broaden their thinking, enrich their imagination and avoid the scoring of low and high scores The phenomenon. How to guide students to design three-dimensional works and finished product design, the author after several years of exploration, summed up some common ways of thinking. First, the paradigmatic way of thinking This is from the specific nature of the existence of things, to develop in depth, in order to achieve better performance and more complete function of the way of thinking. Like today’s analog television signal reception system, image quality is hard to come to the next level, no matter how the circuit improves. Only by changing the analog signal to a digital signal and changing the television receiver from analog to digital receiver can image quality be improved. car
