Investigation And Analysis Of The Status Quo Of The Construction Of The Concept Of Mechanics By Public-funded Normal Student

The construction of the teachers' team has become more and more important in the new era.As a free normal student of the reserve teachers,its cultivation plays an irreplaceable role in the construction of excellent teachers.Grasp of the subject teaching knowledge of free normal current understanding,found that the existing problems and puts forward corresponding Suggestions is the precondition for the revitalization of the normal education,is the key to ensure the smooth implementation of a new round of curriculum reform.In the physical sciences building,the mechanics is a foundation,in high school physics teaching,the teaching concept is the premise of law teaching,experiment teaching and exercise teaching,therefore mechanics concept teaching for physics teaching has the very prominent position.Accurate assessment of students' scientific knowledge learning ability requires a complete set of measuring tools.FCI is a scale for measuring the learning level of students' mechanical concepts,which has been widely used since the development.Based on H normal university as an example,this paper use mechanics concept test tool for investigation,the H normal university after reading and non free normal students' concept of physical and mechanical construction present situation has carried on the questionnaire survey,students from the mechanics concept of cognitive pattern and free normal and not normal mechanics concept construction level of the differences between the two aspects are analyzed and expounded.By using the method of the analysis of the concentration of free normal and not normal cognitive model to study the types of the mechanical concept,summed up the free normal mechanics concept and the students' cognitive model,and use the spss20.0 software,an independent samples t test of FCI measurement results,the mechanics concept construction level in gender,major and whether there is a difference in the core knowledge dimension.Finally compiled by the questionnaire,the author of 109 students(free normal physics,physics,physics teachers and the students)on mechanical concept of learning situation investigation,get the following conclusions:(1)the correct rate of each subject in the FCI test is generally higher than that of non-normal students;(2)the accuracy and concentration of the test results of the mechanical concepts of free normal students and non-normal students are generally higher,indicating that the cognitive model of mechanical concepts is good;(3)free normal in most knowledge is given priority to with correct concept model,but on the instantaneity and speed the understanding of the concept of force.does not form the core of the important concepts,has a certain degree of scattered;(4)there was no significant gender difference in FCI test between free normalstudents and non-normal students;(5)the construction level of the mechanics concept of free normal students is not balanced on the six different knowledge dimensions of the concept of mechanics;(6)there is an inconsistency between the actual construction level of the mechanical concept of free normal students and its subjective cognition.Finally,the author puts forward three Suggestions on how to improve the learning ability of the concept of mechanics.(1)fully understand the origin and establishment process of the concept of mechanics;(2)find and create a life situation closely related to the concept of mechanics;(3)prevent the forgetting of conceptual knowledge.
