A Study On The Concepts And Rules Of "Electromagnetic Induction" In Middle School Physics On The Basis Of Learning Progression

In order to adapt education to the development of the new era,many countries put forward education reforms in the last century.In order to reduce students' excessive content in the learning process,the education reform has proposed the 'core concept'.The core concept is to highly summarize the contents of various disciplines and allow students to learn "Fewer,clearer and higher" content.For students,the core concept is too refined and has no actual content.Learning only the core concept is very difficult and is not conducive to the use of the core concept.At this time,educational scholars proposed the learning theory of "learning progressions." The basis of learning progress is the student's own learning process.The process of learning the core concepts is considered to be a process of continuous improvement from low to high.This step-by-step teaching method is conducive to reducing the difficulty of students' knowledge construction and helps teachers to master student learning more accurately."Electromagnetic induction" is a very important part of the curriculum standard from elementary school to high school.Many students find it difficult to learn.Therefore,this study is based on learning progressions theory.The level of student knowledge,after the end of the previous teaching cycle,as a late concept.From elementary school to high school,we have established an advanced level of "electromagnetic induction" to help students overcome learning difficulties.Provide a reference for teachers' teaching.This study is divided into two aspectsStudy one: Establish learning progressions assumptions.Analyze the content of “electromagnetic induction” in the curriculum standards and textbooks from primary school to high school,identify students' learning objectives and previous concepts,and assume students' learning processes.Teachers guide students to learn according to the hypothesis of advanced process.After learning,by preparing the test questions,all grades of students have undergone "electromagnetic induction" tests.Study students' mastery of learning and knowledge,and establish a learning progress.Study two: Research on Teaching Design Based on learning progressions in "Electromagnetic Induction".Take "Faraday's Law of Electromagnetic Induction" as an example.According to previous studies,students have difficulty learning electromagnetic induction content.Based on a scientific learning process,scientific teaching design can be designed.The teaching plan enables students to correctly understand and apply the "Faraday's law of electromagnetic induction" to reach the learning end.The conclusions to be drawn from this study are:First: By studying the learning situation and curriculum standards of elementary,middle school and high school students,it can be found that the student learning process is indeed a continuous process.A knowledge point may begin to step in from the primary school stage.Second: Through a comparative study of curriculum standards and teaching materials in various countries and regions,students' learning processes have been constructed.By comparing the test results with the learning hypothesis level,we can confirm the scientific nature of the learning study process.According to the test results,students' difficulties and learning levels in the learning process can be clearly seen.According to the student's learning situation,reasonable teaching design can reduce students' learning difficulties and can reduce the span between levels.Make it easier for students to learn,and their knowledge is more reliable.
