向幼儿渗透一些现代数学思想,是幼儿园教育内容现代化的必然趋势。现代数学思想是很丰富的,根据现行《幼儿园计算》教材和幼儿的年龄特点,我们选用了集合、对应、函数等一些简单的内容进行了实验教学。一、集合思想的渗透从集合的表示方法看,我们在实验教学中主要采用韦思图法(即用一条封闭的曲线把所给的元素圈起来,表示一个集合,通俗称它为集合圈)向幼儿渗透,主要渠道有: 1.用多种形式表示一类事物的集合。例如,画圆圈或方框表示:若表示2条金鱼的集合,即在一个圆圈中画上两条金鱼。又如,套底色表示:若表示5只蝌蚪的集合,可套上浅绿底色衬托5只蝌蚪(底色周围相当于集合圈)。此外还有其他形式的表示方法,如表示4只苹果的集合,可将4只苹果放在一只盆子里等。
Infiltrating some modern mathematical thoughts into young children is an inevitable trend of kindergarten education modernization. Modern mathematical thinking is very rich. According to the current “kindergarten computing” teaching materials and the age characteristics of young children, we use some simple contents such as collection, correspondence, function, etc. to conduct experimental teaching. First, the collection of ideas infiltration From the set of representation, we mainly used in the experimental teaching Weiss diagram method (that is, with a closed curve to give the elements of the circle, said a collection, popularly called it a collection circle) The infiltration of infants, the main channels are: 1. In a variety of forms that a collection of things. For example, a circle or a box means that if two goldfish are represented, two goldfish are drawn in one circle. In another example, the set of background colors means that if a collection of five tadpoles is set, five tadpoles can be put on a light green background (the circle around the background is equivalent to a collection circle). In addition, there are other forms of representation, such as a collection of four apples, four apples can be placed in a pot and so on.
