创设真实情境培养科学精神——一节“双新”示范课的尝试与反思

Creating Real Situations and Cultivating Scientific Spirit:An Attempt and Reflectior on a"Double New"Demonstration Class

新课程和新教材对情境教学提出较高要求,学生在情境中发现数学问题,通过数学建模解决实际问题是新课程、新教材倡导的主流教学逻辑。合理创设情境、正确解读情境是培养数学核心素养的关键途径,也是学业质量水平的重要衡量标准,更是锤炼科学精神的重要基石。本文通过一个实际情境,提取其中的数学模型,并构建分析模型、修正模型、推广模型的思维链,培养学生的科学精神,提升核心素养。

The new curriculum and new teaching materials(hereinafter referred to as"Double New")have higher requirements for situational teaching.Making students discover mathematical problems in situations and solve practical problems through mathematical modeling is the mainstream teaching logic advocated by"Double New".Reasonably creating and correctly interpreting situations is the key to cultivate core mathematical literacy,an important measure of academic quality,and an important cornerstone for tempering scientific spirit.This article extracts the mathematical model from a practical situation,and constructs a thinking chain of model analysis,model correction,and model promotion to cultivate students'scientific spirit and enhance their core literacy.
