核心素养视角下的美国数学课堂情境教学方式研究

Research on Situational Teaching in American Mathematics Class from the Perspective of Key Competency

美国的核心素养教育强调为学生未来的生活和工作做好准备,因此,在进行数学教学时,就着重强调教授学生运用、操控与真实世界和现实问题相关的科学和数学思想来学习,具体到课堂实践中就是情境教学。情境教学成功实施的关键是良好的课堂互动,教师可以通过定位、明晰化、详细阐述、参照、评价等方式围绕书面情境任务进行互动。我国数学教育可借鉴美国经验,创建各种有利于情境教学的环境,并通过有效的课堂互动,提高学生学习效果,让学生更加了解学习数学在课堂之外的目的和意义。

The key competency education in America emphasizes the preparations of students'future life and work.Therefore,an emphasis is placed on teaching students how to use mathematics in practice and get scientific and mathematical ideas for study related to the real problemsin the real world,to be more exact,practical teaching in class is situational teaching.The key to successful implementation of situational teaching is good classroom inter action.Teachers and students can interact each other through positioning,clarifying,elaborating,referencing and making comments on contexts.The mathematics education in China can draw some lessons from American experi ence to create a variety of environments conducive to situational teachingand to improve the students'performance through effective classroom interaction,thu
