The Study On Learning Progressions About The Core Concepts Of Electromagnetism In Senior Physics

In recent years,it is found that Learning-Progressions affect significant on the curriculum reform promotion,teaching and evaluation.The exploration of Learning Progressions helps to promote the the combination of curriculum,teaching materials and evaluation,and thus it is one of the hot research problems in educational circles.Learning Progressions is the typical thinking-development approach in learning a subject or a core concept over a period of time,this may be expressed as the way of understanding the knowledge in the students' mind from the shallower to the deeper,from simple to complex,and may also be represented a series of conceptual development sequences.Electromagnetism is an important and difficult part of in high-school physics.In order to understand the student thinking-development sequence,the research background is analyzed in this study.According to the existing research learning to build a concept or a subject for the Learning Progressions hypothesis,developing measurement tools and the implementation of measurement,testing and modifying the Learning Progressions hypothesis are currently the main process of Learning Progressions,so this study is divided into two parts.The first part is the construction of Learning Progressions about the electrostatic field and the dc circuit.First of all,sort out the main concepts and curriculum requirements of the two parts of the static electric field and the dc circuit and draw a concept map based on the carding of the general high school physics curriculum standards,the compulsory education physics curriculum standard,the teaching materials for senior high school and the college entrance examination syllabus.Then according to the domestic and international related research,construct the two part of the Learning Progressions hypothesis.The second part: verification hypothesis.According to the construction of the Learning Progressions hypothesis,develop measurement tools and get the "learning situation questionnaire of electromagnetism",A survey was conducted among two classes of students in a senior high school in Yibin,and then apply two-dimensional type analysis to the accuracy rate and concentration of the survey result,determine what may happen in the learning process of students.Verify the assumptions made in the first part.Finally come to the conclusion of this study,the Learning Progressions of the static electrostatic field and the dc circuit.
