无效教学就是教师在做无用功,对学生知识储备和能力提高等都没有什么帮助。小学数学学习是基础阶段,后续的初中学习和高中学习乃至于大学学习,都受小学阶段学习习惯和思维习惯的影响。教师的教学理念决定教学的方法选择,而教学方法的选择直接影响教学效果的高低。老师首先要对其敢于质疑的行为作出表扬,要充分尊重学生的想法,尤其是对于学生提出的有价值的问题要放到全班范围内组织学生一起分析探讨。 Invalid teaching is that teachers are doing useful work, the students knowledge reserve and ability to improve and so will not help. Primary school mathematics learning is the basic stage, followed by junior high school and high school and even university studies, are subject to the impact of primary school learning habits and habits of thinking. The teaching philosophy of teachers determines the choice of teaching methods, and the choice of teaching methods directly affects the level of teaching effectiveness. Teachers must first praise their daring to question, to fully respect the students’ ideas, especially for the students put valuable issues to be placed within the scope of the whole class to organize students to analyze and discuss.
