Primary School Students To View Preliminary Understanding Of Testing And Analysis

"The Standards of Mathematics Curriculum for Compulsory Education (Trial Draft)" issued by Ministry of Education of People's Republic of China in 2001 clearly stated that space and shape should be an integral part of school mathematics to develop students' spatial conception (ability) in China. Introduction to orthogonal views (IOV) as one of new topics appeared in the new Standards at primary school level. Therefore, it is urgent and necessary to investigate primary school students' cognition of IOV. According to some researches and curriculum sets, the author designs an IOV test. 405 pupils with different acquaintance from Grade 2 to Grade 6 were surveyed and 41 of them were interviewed.It was found that : First, pupils' from grades 2-4 who have learned or contacted IOV don't have significant cognition differences between grades. Second, pupils who have learned or contacted IOV performed as good as or even better than those who haven't learned or contacted. Third, pupils' cognition development of IOV's three dimensions (identify pictures, read pictures and draw pictures) are keep in pace. From analysis of pupils' cognition of three set aspects (from reality to reality-Ⅰ, from reality to mathematics- Ⅱ, from mathematics to mathematics-Ⅲ), it was found that pupils are inclined to aspect Ⅰ and Ⅱ. Fourth; there are some mistakes aroused by intuition thinking of pupils in this domain. Fifth, pupils don't have significant sex differences in cognition of IOV. Sixth, the International Mathematics Olympic (IMO) training has influence on pupils' cognition in grades 2-4, but disappears at grade 6.Basing on the findings of this study, some suggestions for primary school teachers and curriculum developers were given at the end of this thesis.
