Research On The Scientific Information Literacy Of Science Teacher Students Based On The Rasch Model

The highly information-based age has brought unprecedented opportunities and challenges to people’s study and life.Information literacy has become an ability as important as traditional reading,writing and calculation.The improvement of information literacy can far effectively achieve educational goals.The cultivation of information literacy becomes great significance for individual development and lifelong learning.Information literacy is the core of lifelong learning,and lifelong learning is the idea that contemporary normal university students must establish and adhere to.Therefore,mastering the information literacy level of normal university students can promote the teaching.Based on the domestic and overseas research with information literacy,combined with the characteristics of science normal university students,and on the basis of the existing theoretical framework,this paper attempts to construct the model of science normal university students’ scientific information literacy.According to the model of science information literacy of normal university students,the measurement tool of science information literacy of normal university students is constructed.According to the different information literacy ability of students,the information literacy level of students is divided into four levels:aggregation type,transformation type,regrouping type and feedback type,and the specific behavior and performance of students at each level are described in detail.The Rasch model was used to test each level.The data obtained by the test met the expectation of Rasch model,and the measurement scale had good reliability and validity.The results show that there is a significant difference in the level of information literacy among freshmen,sophomores and juniors.Secondly,the research results also show that the better the entrance score of students,the higher the level of information literacy.In the first round of the test,the samples were normal university students in colleges and universities.In the second round of students’samples,undergraduates from a key university were selected as samples.The students’ ability horizontal distribution shows that in line with Rasch model,and the without centralization,and most of the students were in high-level areas.Information literacy is a comprehensive assessment of normal university students.Mastering students’information literacy level in real time can not only improve the teaching quality of school education,but also improve students’ personal ability and help students to realize their ideals.There are still many deficiencies in this paper,and the division and definition of the level still need to be further refined,so it is necessary to continue to explore,try and modify,and build a more reasonable capability model.The follow-up research should continuously explore the factors affecting the information literacy ability of normal university students,and propose strategies and courses that can improve students’information literacy.
