在高中数学教学中,如何根据数学课程的理念和目标以及学生的认知特征,合理选择教学模式,让学生的思维活起来?合作探究是其根本所在。“学生的数学学习活动不应只限于接受、记忆、模仿和练习,高中数学课程还应倡导自主探索、动手实践、合作交流、阅读自学等学习数学的方式。”《普通高中数学课程标准》如是说。一、教学实录赏析笔者最近在“江苏省南通市数学学会第十届二次年会”上听了有关苏教版选修2-1《空间角的计算》的一节公开课。课堂亮点
In high school mathematics teaching, according to the idea and goal of mathematics curriculum and students’ cognition characteristics, how to choose teaching mode rationally and make students think of life? Cooperative exploration is its fundamental. “Students’ mathematics learning activities should not be limited to accepting, remembering, imitating and practicing. High school mathematics curriculum should also advocate self-exploration, hands-on practice, cooperation and exchange, and reading self-study to learn mathematics.” “ So said. First, the teaching record appreciation The author recently ”Nantong City, Jiangsu Province, the Tenth Second Annual Meeting “ on the Soviet version of the elective 2-1 ”space angle calculation" an open class.
