课堂生成与预设是课堂教学永恒的话题,他们是一对矛盾而和谐的统一体。小学数学课堂中学生的学习情况随时都会发生变化,随时都会出现一些意想不到的状况,生成一些新的教学资源,教师适时把握合理运用这些资源,可以使学生顿然领悟,提升教学效果,让课堂更为灵动。一、捕捉生成资源,激活课堂学习氛围每位有责任心的数学教师都会在课前精心设计教案,包括如何有效营造课堂学习氛围,激发学生的学习热情,让全体学生积 Classroom generation and presupposition are the eternal topics in classroom teaching. They are a contradictory and harmonious unity. Primary school mathematics classroom students learning changes at any time, at any time there will be some unexpected situation, to generate some new teaching resources, teachers timely grasp the rational use of these resources, students can suddenly comprehend, improve teaching effectiveness, make the classroom more Smart. First, to capture the generation of resources to activate classroom learning atmosphere Each responsible mathematical teacher will be carefully designed lesson plans before the lesson, including how to effectively create a classroom learning atmosphere, to stimulate student enthusiasm for learning so that all students
