高中数学中所倡导的“学案教学”方式给学生更多的自主学习空间,有利于提升学生的创新能力和学习能力,使学生可以在教师提供的学案的指导下独立进行学习。然而,在现实中应用学案教学的模式出现了课堂低效的现象。本文在分析造成这种现象的原因的基础,提出了应对课堂低效的策略,以此来提升高中数学应用“学案教学”的有效性。 The “case study teaching” mode advocated in high school mathematics gives students more room for independent study, which helps to improve students’ ability of innovation and learning so that students can learn independently under the guidance of the case provided by the teacher. However, in reality, there is a phenomenon of classroom inefficiency due to the model of case study teaching. Based on the analysis of the causes of this phenomenon, this paper proposes strategies to deal with the ineffectiveness of the classroom in order to improve the effectiveness of high school mathematics teaching.
