教育部颁发的《幼儿园教育纲要》(试行草案)计算部分中规定:“要求大班儿童学习将一个实物或形体等分成二份、四份,知道原实物或形体比每一份大,每一份都比原实物或形体小。”为了掌握大班儿童在学习等分过程中的特点,确定等分教学的具体要求、方法,以及探讨通过等分教学发展幼儿的观察力、判断推理能力和培养幼儿思维的灵活性等问题,我们进行了个案调查和教学实验,现小结如下: 幼儿理解等分的特点1.幼儿对等分的理解和他们的生活经验有密切联系。例如,当老师问:“一个苹果要给两个小朋友吃,每个人要吃一样大,应怎么分?”几乎百分之百的幼儿能凭生活经验感知一个物体的二等分,就是分成两份一样大的物体,因为幼儿在日常生活中经常接触到一个物体分成两份一样大的事例。当
The calculation section of the “Kindergarten Education Outline” (tentative draft) issued by the Ministry of Education stipulates: “Students in large classes are required to divide a physical or physical body into two or four equal parts, knowing that the physical object or body is larger than each one, Are smaller than the original physical form. ”In order to grasp the characteristics of children in large classes in the process of equate learning, to determine the specific requirements of teaching equal, methods, and explore the development of children through equal teaching observation, to judge reasoning ability and to nurture children Thinking flexibility and other issues, we conducted a case study and teaching experiments, are summarized as follows: Children understand the characteristics of equal points 1. Children’s understanding of the sub-division and their life experience are closely linked. For example, when the teacher asks, “An apple needs to be eaten by two children and each one wants to eat as much as one should eat?” Almost 100% of toddlers perceive a bisexuality of an object based on their life experience, Because children often touch an object in their daily life and divide it into two equally large cases. when
