Advanced Study Of Learning Important Concepts In High School Biology

"Big concept" is the backbone of subject knowledge and structure,which plays the role of subject skeleton."Learning progression" is a description of a student's thinking path as they learn and explore a topic.It has always been the focus of the education circle to take the big concept as the pillar to avoid too much and miscellaneous mechanical learning.In the concrete teaching practice,the big concept is superior,and the abstractness and generality are too strong.Therefore,the important concepts in the lower position should be taken as the starting point in the implementation of "teaching around the big concept".In recent years,the theory of "learning progression",introduced by the international science and education circles,has become a hot topic in many subjects.The theory of "concept teaching" and "learning progression" is the focus and hot spot of Chinese educational circle.This study focuses on the module of "steady state and regulation".Through literature review,it is found that there are few researches on this module,and the research guided by the theory of "learning progression" is even more rare."Therefore,this study is expected to help teachers and students deepen their understanding of the important concepts of this module and provide some help for teaching practice.The specific research and conclusions of this paper are as follows:To screen and identify the important concepts of "steady state and regulation"module.In this study,20 important concepts of this module were summarized based on various materials such as the 2017 edition of the biology curriculum standards of ordinary high schools,the 2019 examination syllabus,and the compulsory textbook of the third edition of the people's education edition.The 20 important concepts were revised and corrected on the basis of investigation and research,and finally classified into five content dimensions.Develop a test tool for the important concepts of this module.The test paper of the research module was compiled for the students,and the results were analyzed by Rasch model.The paper designs the questionnaire of difficulty assignment method and analytic hierarchy process for the teachers,and analyzes the results according to the corresponding method.On the basis of test results,based on the Rasch model method,the term difficult assignment method and analytic hierarchy process(ahp)construct the corresponding advanced path respectively and the advanced level,through the construction process and results of these three methods and the level of the path and content of comparative analysis of the two get three methods characteristics and use of each influence factor.The study results obtained based on the three methods are comprehensively compared to determine the learning path and level progression level of this module.Finally,the main conclusions of this study are as follows:There are 20 important concepts of "steady state and adjustment" module,which are reasonably expressed and highly recognized by front-line teachers;Important concepts are divided into four levels,which can provide reference for future research;The construction of learning advanced path can make comprehensive use of a variety of methods,in this study,the use of three methods to study the same module should be the first,it is necessary to prove that the methods complement and perfect each other.
