Advanced Study Of Electrostatic Field Learning In High School Based On Rule Space Model

In the face of the international competition in the information age and the challenge of talent training in the 21st century,many countries have carried out a new round of curriculum reform on the basis of summing up a large number of research results and curriculum implementation experience.Core literacy has become a hot spot in China's educational reform.While paying attention to the condensed core literacy,we should also pay attention to the scientific education reform caused by the advanced learning(learning progression)at the same time.In this study,under the theoretical background of cognitive measurement,using regular space model,the concept of "electrostatic field"space model.First of all,using text analysis method,combing the key concepts of "electrostatic field" in curriculum standards at home and abroad,and analyzing the connotation and extension of physical concepts from the perspective of knowledge content,the relationship between physical concepts,Then according to the trend of college entrance examination proposition to refine the specific concepts students need to master.According to the logical order of knowledge and referring to the law of students' cognitive development,an advanced model of electrostatic field learning is constructed,and the learning performance of students at six levels is defined.Secondly,according to the key concept of "electrostatic field ",the hierarchical model of the concept attribute of electrostatic field is constructed,and the identification degree of attribute model is investigated by interview method to ensure the reasonable and effective construction of attribute level.By using the concept attribute hierarchy and based on the regular space model,the adjacency matrix,reachable matrix and Q matrix were established to obtain 24 kinds of ideal attribute mastery patterns and ideal response patterns.The same line teachers worked out cognitive diagnostic measurement tools with good reliability and validity,and coded cognitive diagnostic measurement tools.The test of electrostatic field cognitive diagnosis was carried out on 368 senior middle school students in Ningxia Hui Autonomous region.The test paper is scientific and reasonable.Using parameter estimation,using Winsteps?SPSS?Matlab software to process data to establish rule space,obtained 24 pure regular points and 368 points to be classified,classified 368 sequence dual points,finally obtained 19 typical property master modes,showed Coulomb law in electrostatic field,the relationship between static power work and potential energy,and the comprehensive application flexibility of knowledge need to be strengthened.The results showed that most subjects were at a hierarchical level level 5.Analysis of the test individual diagnostic results showed differences in individual cognition.Finally,the learning advanced path diagram based on the regular space electrostatic field is drawn out and obtains 3 learning paths.The study of the following conclusions:(1)through matrix construction,a total of 24 master mode(2)preparation test tool reasonable and effective(3)according to the discrimination to different attributes master the student ability average,(4)regular space model(5)individual cognitive differences,learning has multiple paths.
