关注学情,优化“三步五环”之有效课堂教学模式的实施,可以有效激发学生自主学习的内动力,促进学生数学素养的有效发展。本教学模式是在关注学情的基础上,提出了课堂教学讲、练、导这三步,并提出了在数学课堂教学中,要有精确目标、精炼讲授、精准练习、精心指导、精简反馈这五大环节。 Concerned about the learning situation and optimizing the implementation of the effective classroom teaching mode of “three steps and five rings” can effectively stimulate the internal motivation of students ’autonomous learning and promote the effective development of students’ mathematical literacy. This teaching mode is on the basis of paying attention to the situation and puts forward three steps of teaching, training and guidance in classroom teaching. It puts forward that in mathematics classroom teaching, we should have precise target, refined teaching, accurate practice, careful guidance and streamlining feedback These five areas.
