Research On Core Ideas Of Force And Their Learning Progressions In High-school Physics

With science and technology developed,it’s a grand challenge that teachers integrate knowledge into limited teaching and make students to solve problems with core knowledge and skills for teachers to solve urgently.And it’s necessary to study the core concepts and advanced learning in order to better design and evaluate teachers’ education and students’ learning.This research chooses Kunming Yiliang No.2 middle school that has online teaching lessons and completed the following work.First analyzing the teaching contents around the core concepts at home and abroad by sorting out the core concepts and learning advanced research to define the core concepts and find the search criteria.Second,we have retrieved the core concepts of physics and force in high schools through using textbook,analyzing gaokao examination,organizing concept maps,interviewing with teachers.Third,classifying the questions of force concept inventory into the mentioned core concepts and questionnaires were used to survey the students of two classes in the Kunming Yiliang No.2 middle school.Fourth,by using the two-dimensional type analysis of the correct rate and concentration ratio,the advanced learning level was obtained.And based on the result teachers should evaluate and reflect on teaching.We have found these following conclusions of this research.First,the search established six core concepts of high school physics force part.Second,the teaching results obtained by adopting the class that has online lessons are satisfactory.And the students in this class are better in all aspects than other class student.
