                高中数学教学中“问题解决”教学思路的实施

                时间:2018-10-29 来源:中国校外教育 作者:郑显辉 本文字数:1879字

                  摘    要:星云棋牌官网下载 “创新和实操”是素质教育的关键所在。数学思维是“创新和实操”在数学知识传播过程中的风向航标,是极其核心的数学素养。对如何提升学生的数学思维能力进行了一段时间地探索,现将成果呈现给大家,希望大家不吝赐正。

                  四、“问题解决”授课思路的实施步骤

                  1.塑造情境,提高学生数学的学习兴趣

                  由现实情况入手,把有待解决的问题和学生实际学习能力进行有机结合,这样一来,学生容易进入和问题相联系的情境当中,进而提高学习兴趣。
