目前,在教学中存在一种现象:教师为完成所谓的“知识”教学任务,按预定的教案、教学思路教学,绝不允许学生出“格”。这样的课与新课程理念背道而驰,是没有生命活力的。因此在科学课堂运用动态生成式的教学,能使课堂充满生机。一、科学课堂教学中,巧妙利用生成性资源动态生成式的课堂,不能只强调学生主体性,而忽视教师的主导性。教师一方面要为学生自主学习创造条件;另一方面要把握好课堂组织权,进行有效的生成。具体地说就是要在教学活动进行的过程中,了解学生自主学习的情况,并 At present, there is a phenomenon in teaching: the teacher does not allow the student to get out of school in order to complete the so-called “knowledge” teaching task and teach in accordance with the predetermined lesson plans and teaching ideas.
