数学探究课堂教学个案研究——兼谈教师的适应与挑战

Case study on mathematical explorative teaching in the classroom

数学探究课如何组织 ,许多教师感到困难和困惑 ,以“四边形的内角和”的探究教学为案例进行评析。教师应有宽厚扎实的数学功底 ,具备能创设问题情景、能在教学中搭适当的“脚手架”的技术 ;树立“以学生发展为本”和“学生参与”的教学观念 ,具有能进行灵活的教学设计和加工、采用对话与交往的形式进行教学的技能 ,把握“讲授”与“探究”的适度平衡。

It is very difficult for many teachers how to organize the mathematical exploration in the classroom, and lots of teachers feel puzzled with it. Through the comment and analysis of mathematical exploration on sum of internal angle of the quadrilateral in the classroom, the teachers should improve the ability in mathematics and the technique of teaching.
