《高中数学新课程标准》指出:学生的数学学习活动不应只限于接受、记忆、模仿和练习,在高中数学教学中还应倡导自主探索、动手实践、合作交流、阅读自学等学习数学的方式。这些方式有助于发挥学生学习的主动性,使学生的学习过程成为在教师引导下的“再创造”的过程。因此高中数学课堂教学应力求通过各种不同形式的自主学习、探究活动,让学生体验数学发现和创造的历程,增强他们的创新意识。所谓小组化教学是指在数学教学过程中,学生在小组或团队中经过自主 The New Curriculum Standard for High School Mathematics indicates that students’ math learning activities should not be limited to accepting, remembering, imitating and practicing. In high school mathematics teaching, they should also advocate ways of learning math such as self-exploration, hands-on practice, cooperation and exchange, and reading self-study . These methods can help to develop students’ initiative and make the process of learning become “re-creation” under the guidance of teachers. Therefore, high school mathematics classroom teaching should strive to explore activities through various forms of autonomous learning, so that students experience the process of mathematical discovery and creation, enhance their sense of innovation. The so-called group teaching refers to the process of teaching mathematics, students in the group or team autonomy
