顺学而教:加速小学生对数学知识本质感悟——以“角的初步认识”教学为例

Teaching According to Learning: Accelerating Primary School Students’ Understanding of the Essence of Mathematical Knowledge——A Case Analysis of“Preliminary Understanding of Angles”

顺学而教是落实以学生为主体基本教学理念的体现,是2022年版新课标精神贯彻的具体实践。文章在“角的初步认识”教学中,把脉小学生的生活积累和认知水平,精准地解读教学内容,研透知识联系,以此为基点开展较为科学的教学预设,以实现顺学而导,助推表象建构。在此过程中,教师要引导学生进行必要实践操作活动以及学习分享与争辩活动,最终实现学习理解的突破,促进学生对角的本质有着较好感悟,加速角的认识科学建构。

Teaching according to learning is the embodiment of the basic teaching concept of taking students as the focus and the specific practice of implementing the spirit of the new curriculum standard 2022. In the teaching of “preliminary understanding of angles, the article examines the life accumulation and cognitive level of primary school students, accurately interprets the teaching content, and thoroughly studies the knowledge connection to carry out more scientific teaching presupposition, based on this, to realize the guidance of learning and boost the construction of representation. In this process, teachers should guide students to carry out necessary practical operation activities and learning sharing and debate activities to finally achieve a breakthrough in learning and understanding, promote students to have a better understanding of the essence of the angle, and accelerate the scientific construction of the angle.
