观察,是人们认识世界的第一步,是思考、积累、表达的前提,是智慧的源泉。教师应帮助学生学会观察,能有效地解决数学知识抽象性与学生思维具体性之间的矛盾,能引导学生将看到的现象提炼成数学知识,实现有效建构,促使学生的知识与思维不断深化,能力与智慧不断提升。然而,在当前课堂教学中,学生观察往往随心所欲、浮于表面,没有真正发挥观察的作用、体现观察的价值。教师要根据教学实际,引导学生进行二次观察,让学生练就一双观察的慧眼,在观察中理解知识、发现规律、解决问题。一、二次观察,训练思维的有序性小学生特别是低年级学生的思维处于从无序向有序过渡的阶段。他们对事 Observation is the first step in people’s understanding of the world, the premise of thinking, accumulating and expressing, and the source of wisdom. Teachers should help students learn to observe, can effectively solve the contradiction between mathematical abstraction and students ’specific thinking, can guide students to see the phenomenon into mathematical knowledge, to achieve effective construction, to promote students’ knowledge and thinking of deepening , Ability and wisdom continue to improve. However, in the current classroom teaching, student observation is often arbitrary, floating on the surface, did not really play the role of observation, reflect the value of observation. Teachers should guide students to conduct secondary observation according to the actual teaching so that students can acquire a pair of eyesight to observe, understand knowledge, discover laws and solve problems in observation. First, the second observation, the order of training thinking The thinking of primary students, especially students in lower grades, is in the transition from disorder to order. They are right
