以往小学数学教学中普遍运用封闭式教学法,这使得数学教学过于集中地管理学生,让学生处于被动状况,难以发展个性,这在一定程度上限制了学生的创造性思维,不利于学生有效学习。随着教育领域改革的不断深化,小学数学教学应当摒弃封闭式教学法,合理实施开放式教学法,在数学课堂上创造相对开放、自由、轻松、愉悦的环境,鼓励学生积极主动地参与学习活动,发挥学生的主观能动性,同时培养学生的创造性思维及能力,促进学生个性化、全面化发展。所以,小学数学开放 In the past, closed-end teaching method was generally used in elementary mathematics teaching, which made mathematics teaching manage students too much, let students in a passive condition, and difficult to develop personality. This restricted the creative thinking of students to a certain extent, which was not good for students to learn effectively. With the continuous deepening of reform in the field of education, elementary mathematics teaching should abandon the closed teaching method, implement the open teaching method reasonably, create a relatively open, free, relaxed and pleasant environment in mathematics classroom and encourage students to actively participate in learning activities , Give full play to students’ subjective initiative, cultivate students’ creative thinking and ability, and promote students’ individual and comprehensive development. So, elementary mathematics is open
