核心素养视角下小学数学课堂情境创设问题与改进研究
|
摘要
发展学生的核心素养,必须创设真实的数学问题情境,让学生在情境中体验、思考,这已成为当前小学数学课堂教学的基本环节。然而,由于一线教师对课堂情境创设的含义、价值和目的性认识不足,以至于在实际课堂中普遍出现创设的情境缺乏目的性、数学学科性、学生探究的趣味性和脱离儿童年龄特征等问题。因此,需要教师在创设课堂情境时从立足教学目标、激发学生探究数学问题的兴趣、培养数学问题意识和进行充分的数学表达方面加以改进,以使每一节小学数学课堂教学都能达成培养学生核心素养的目标。
In order to develop students'core accomplishment,we must create a real mathematical problem situation,let students experience and think in the situation,which has become the basic link of current primary school mathematics teaching.However,due to the lack of understanding of the meaning,value and purpose of classroom situation creation by front-line teachers,there are many problems in the actual classroom,such as lack of purpose,lack of mathematical discipline,lack of interest in students'inquiry and separation from the characteristics of children's age.Therefore,it is necessary for teachers to set up classroom situations based on teaching objectives,stimulate students'interest in exploring mathematical problems,cultivate students'awareness of mathematical problems and carry out adequate mathematical expression so that every primary school mathematics classroom teaching can achieve the goal of cultivating students'core literacy.
