课堂生成是新课程改革下所倡导的一个重要理念,预设是教学的基本要求,是教学生成的基础,对教学有促进作用。新课程改革下的数学教学更需要教师在精心预设的基础上,结合教学实际进行灵活调整,及时捕捉动态生成,把握课堂教学中闪动的亮点,从而使数学课堂在预设与生成的融合中焕发出其特有的活力。那么,要焕发出数学课堂的活力,就要在充分、精心预设的前提下,随时准备应对课堂中的各种生成。
Classroom generation is an important idea advocated under the new curriculum reform. The presupposition is the basic requirement of teaching, which is the foundation of teaching and plays a catalytic role in teaching. Under the new curriculum reform, mathematics teaching also requires teachers to make flexible adjustments based on meticulous preconditions and actual teaching, to capture the dynamic generation in time and grasp the flashing highlights in classroom teaching so as to make the maths classroom converge in the preconceived and the generated Glow in its unique vitality. So, to rejuvenate the vitality of the mathematics classroom, we must be fully and carefully preconditions, ready to deal with a variety of generation in the classroom.
