分组实验是数学教学中的有机组成部分.它能有效地培养学生的动手能力和观察能力,能充分发挥学生的主观能动性,调动学生的学习兴趣,增强集体观念与协作精神.笔者在数学课堂教学设计中,一直寻求教学模式的改变,意在体现学生的主体地位,重视学生各种能力的培养.新课程标准指出:“数学教学应当努力提高学生的学习能力,即使学生成为‘自主的学习者’.”“数学教学的设计应当促进所有学生的数学学习.”建构主义观
Group experiment is an integral part of mathematics teaching.It can effectively develop students’ abilities of practice and observation, give full play to the students’ subjective initiative, arouse students’ interest in learning, and enhance the concept of collective and collaborative.The author in mathematics classroom teaching Design, has been seeking changes in teaching mode, intended to reflect the dominant position of students, focusing on the cultivation of students’ abilities.New curriculum standard states: “Mathematics teaching should strive to improve students’ learning ability, even if students become ’autonomous learning ’’ The design of math teaching should facilitate all students’ math learning. ”" Constructivism
