一、创设有效的问题情境教师要创设适当的问题情境,让学生主动地学习,自主发现数学的规律和问题解决的途径,使他们经历知识形成的过程,通过展开探究,讨论,理解等活动,促使学生在问题情境中进行科学严谨的探究,达到解决问题的目的。(一)创设问题情境,激发学生学习数学的兴趣。教师巧妙地创设问题情境,既能使学生情趣盎然,又可激发学生强烈的求知欲望,把“要我学”转变成“我要学”。例如,教学“概率”时,首先 First, to create an effective problem situation Teachers should create appropriate problem situations, so that students take the initiative to learn and discover the laws of mathematics and the way to solve problems, so that they experience the process of knowledge formation, through the exploration, discussion, understanding and other activities, Promote students in the context of the problem of scientific rigor, to solve the problem. (A) create a problem situation, stimulate students interest in learning mathematics. Teachers skillfully create problem situations, both to make students interesting, but also stimulate students’ strong desire for knowledge, the “want me to learn ” into “I want to learn ”. For example, teaching “probability” when first
