近年来,情境创设、合作探究等研究的人很多,但对于练习却研究者甚少。是不是练习不重要呢?其实不然。就数学而言,每一堂课都离不开练习,只不过练习的目的不一样。新授课的练习是为了巩固新知,练习课的练习是为了拓展提高,复习课的练习是为了建构体系。新授课可以是一次自主建构的练习之旅,练习的过程中也可以拓展新知。所以,练习很重要。一、现状反思1.注重新授,草率练习。办公室里经常看到新授课前,教师精心
In recent years, there have been a lot of researches on situation creation and cooperation exploration, but there are few researchers for practice. Is it not important to practice? In mathematics, every lesson is inseparable from practice, but the purpose of practice is not the same. The practice of new lectures is to consolidate the new knowledge, the practice of practice is to expand the improvement, the practice of review is to build the system. New lectures can be a self-constructed exercise tour, which can also be expanded during practice. So, practice is very important. First, the status quo reflection 1. Focus on new grant, sloppy practice. Often seen in the office before the new lectures, teachers carefully
