我教学北师大版小学数学第七册第二单元《线的认识》一课时,学生在课堂上的表现让我兴奋不已。“线的认识”是一节抽象的概念课,数学中的“起始概念”一般比较难教,弄不好变成师说生听,没有生机、令人乏味的课堂,因此也无法达到预设的教学目标。于是我改变以往的教学思路,换一种教学设计,结果收到了异想不到的效果。现把我课后的欣喜与大家共同分 I teach Beijing Normal University version of elementary school mathematics seventh unit second unit “line of knowledge” a class, the students in the classroom performance made me excited. “Line of knowledge ” is an abstract concept class, mathematical “starting concept ” is generally more difficult to teach, get into a teacher and students say, there is no life, boring classroom, so Also can not achieve the preset teaching goal. So I changed the previous teaching ideas, for a teaching design, the result has received unexpected results. The joy of my class is now shared with everyone
