把生活情境融入数学课堂,使生活问题数学化,是建构主义教学观下的一种新教学理念。本文以《一次函数的图象在物体运动中的应用》这一教学设计为载体,结合笔者在新课程实施两年多来的一些教学尝试和实践初探,提出了创设生活问题情境,激发学生的求知欲;把生活问题数学化,体现数学的应用价值;让数学课堂向生活空间有效延伸等看法,试图通过这些方面的努力,呈现具有生活魅力的数学课堂。
Integrating life situations into mathematics classrooms and mathematicalizing life problems is a new teaching concept under the constructivist teaching concept. This paper takes the teaching design of the application of the image of a primary function in the movement of objects as the carrier, and combines the teaching experiment and practice of the author in the implementation of the new curriculum for more than two years, and proposes to create a situational context of life and inspire students. Knowledge-seeking desire; Mathematicalization of life issues, embodying the value of mathematics; Extending mathematics classrooms to the living space, and attempting to present mathematics classrooms with life fascination through these efforts.
