当前,小学生课业负担过重,教师钻在作业堆里的现象还颇为严重。笔者认为大量的数学课外作业是导致这种现象的主要因素。要减轻师生的负担,关键在于减少课外作业量,而减少课外作业量的根本又在于优化数学练习,提高课堂教学效率。多年来,我着重从“四化”上作了一些尝试。 一、分析科学化。练习是以《大纲》为根据,针对教材内容,按照“循序渐进,螺旋上升”的原则编排的。每道题都渗透着编者的目的和意图,有基本功训练题、基本题、巩固题、复习检查题、综合发展题等。因此,要实现练习优化,教者在设计教学过程时,就得吃透编者意图,全面地、科学地分析每题在教材中的地位和作用。
At present, the primary school students are overburdened with their homework and the teachers are drilled in the homework. The situation is still quite serious. I think a lot of math homework is the main factor leading to this phenomenon. To reduce the burden on teachers and students, the key is to reduce the amount of extracurricular homework, and reduce the amount of extracurricular homework lies in optimizing math exercises to improve classroom teaching efficiency. Over the years, I have focused on some attempts from the “four modernizations.” First, the analysis of scientific. Practice is based on the “outline”, according to the textbook content, in accordance with the “gradual, spiral” principle. Each question is permeated with the purpose and intent of the editor, basic training questions, basic questions, consolidation questions, review questions, comprehensive development questions. Therefore, in order to optimize the practice, when designing the teaching process, the educators have to thoroughly understand the editors' intent and comprehensively and scientifically analyze the status and role of each question in the teaching materials.
