新课程改革以来,如何有效地开展数学教学活动,一直是我们广大数学教师探索的重点。有效的课堂教学不仅要使学生获得数学的知识技能,更重要的是让学生在数学思考、问题解决、情感态度等方面获得全面发展。下面,就如何提高数学课堂教学的有效性谈一点我的做法。一、注重情境创设的有效性目前,问题情境创设的重要性已被广大数学教师所接受,但是这样不能刻意地追求形式,既要注重趣味性,更要注重有效性。如教学“用‘替换’的策略解决问题”时,我创设了如下的情境:欣赏《曹冲称
Since the new curriculum reform, how to carry out mathematics teaching activities effectively has always been the focus of our vast majority of mathematics teachers. Effective classroom teaching should not only enable students to acquire math knowledge and skills, but more importantly, enable students to develop in an all-round way in terms of mathematical thinking, problem solving and emotional attitude.
