教师在数学概念教学中要开拓教学视野,从不同的视角审视数学概念,探寻概念教学的设计途径,引领学生从不同的角度认识、理解数学概念。1问题提出两位笔者在先后担任省市级教学能手评委之后,都会有几分欣喜几分忧虑。优秀选手合理的教学设计,自然的课堂生成,充满思辨的数学味,让人眼前一亮,心生敬佩。而一些选手却照本宣科,对教学内容缺乏深入的思考,对课堂教学缺乏科学的设计,思路单一,课堂干涩无味。特别是“一个定义,三项注意,几道例题,大量练习”的教学现象仍然比较严重。教
Teachers should broaden their horizons of teaching in the teaching of mathematical concepts, examine mathematical concepts from different perspectives, explore the design approaches of conceptual teaching, and lead students to understand and understand mathematical concepts from different perspectives. 1 question put forward two I have successively served as provincial and municipal teaching experts judge, there will be somewhat happy joy somewhat worried. Good players reasonable teaching design, natural classroom generation, full of speculative mathematical taste, people shines, hearts and minds admired. However, some of the contestants did not think deeply about the content of the education. They lacked a scientific design of classroom instruction, and they had a single idea and the classroom was dry and tasteless. In particular, the teaching phenomenon of “one definition, three notes, a few examples and lots of exercises” is still quite serious. teach
