层次化教学是根据学生已有的知识水平和知识经验,以学生学习知识的需求为前提,详细分析学生的自身特点,根据学生自己的学习要求,制定适合他们的学习方法,进而采取相应的教育教学手段,这就是分层教学法的核心内容。教师在“自主探究”和“交流合作”的过程中应充分激发学生的学习积极性,给学生充分展现自我学习能力的机会,在每个活动环节中他们真正获得数学知识与技能、正确的数学思想和方法,成为学习的主人。在进行分 Hierarchical teaching is based on the students ’existing knowledge level and knowledge and experience, taking the students’ learning knowledge as the precondition, analyzing the students ’own characteristics in detail, formulating suitable learning methods according to the students’ own learning requirements, and then taking appropriate education Teaching methods, this is the core content of the layered teaching method. Teachers should fully stimulate their enthusiasm for learning and fully demonstrate their self-learning ability in the process of The correct mathematical ideas and methods become the masters of learning.
