Children On Nutrition Related To The Concept Of Cognitive Research

By defining and explaining the reasons, the research, through interviewing, explores 300 children's cognition about some diet nutrition related concepts such as nutrition, vitamin, vegetable, fat, choosing food, sock, meat or fish, fruit, drink, boiled water. Those children are as diverse as 45 to 80 months old.By generalizing, coding and analysising the results of interview, the researcher finds 11 forms that children define diet nutrition related concepts. These forms are: unknown, incorrect cognition, using original words to make sentences, using concrete examples to illustrate, describing the reasons, describing the results, intuitive features, important properties, and pragmatic functions and families relationships. The children mainly use concrete examples to define concepts.The above mentioned 11 forms are classified to three levels. 28.20% children belong to level one, i.e., lacking understanding of concepts. 56.00% children belong to level two, i.e., define diet nutrition related concepts from concrete objective or intuitive outer features; 15.89% children belong to level three, i.e. define the concepts by non-intuitive inherent properties of objective as well as relationship between people and objects, objects and objects . In addition, through analyzing the quantitative statistics, the research discloses the age, sex, kindergarten features of children's cognitive concepts respectively. The result indicates that there is age difference factors children ability to define the nine concepts excluding boiled water. There are different striking kindergarten differs concerning define picking food and sock. To be specific, the cognitive ability of kindergarten A is higher than that of children in kindergarten B. There are no sex differences.Concerning children's explaining the reason of the concepts: no explanation, incorrect explanation, explaining by intuitive features, by nature, direct result, explaining by direct reasons. The children mainly give explanation by explaining the reasons directly.Based on this, the researcher carries a comprehensive discussion about the children's cognitive features of concepts, draws the conclusion that the cognition may be influenced by the children's thinking ability, life experience, the concept itself and the educational factors and gives some suggestions on children's diet nutritioneducation.Finally, the researcher reflects on the research and puts forward some points that need further improvement.
