数学是一门研究客观世界数量关系和空间关系的逻辑性、相关性及系统性比较强的学科。所以,学习数学时,一线教师需要认真探究课本单元之间的纵横联系和知识结构,同时要注意培养学生的发散思维能力。只有在重视基础知识结构又鼓励发散思维情景下,学生才能发现数学知识的内在联系,抓住数学学习的本质,培养数学思维的敏捷性、独创性和灵活性,从而提升探究问题和
Mathematics is a logical, relevant and systematical subject that studies the quantitative relations and spatial relations in the objective world. Therefore, when learning mathematics, front-line teachers need to carefully explore the textbook unit of vertical and horizontal links and knowledge structure, while paying attention to develop students' divergent thinking ability. Only by focusing on the structure of basic knowledge and encouraging divergent thinking can students discover the intrinsic connection of mathematical knowledge, seize the essence of mathematical learning, develop the agility, originality and flexibility of mathematical thinking so as to promote the exploration of problems and
