Advanced Research On The Core Concepts Of High School Biology

The teaching of core concepts has always been an important method in biology teaching.In recent years,the theory of "Learning Progressions" has risen quietly,and has gradually become a hot spot in the research of Western science education.This theory just tries to answer the question of how students can gradually understand the core concepts along a certain thinking path."Core Concept Teaching" and "Learning Progressions" theory both represent the mainstream trend of teaching research and reform and development in our country to a certain extent.If the two can be combined,it will certainly bring a lot of inspiration to the biology teaching of high school,explore many teaching designs that can improve the quality of teaching,and effectively promote students' mastery of biological knowledge.Through educational practice and literature review,it is known that the research on advanced concepts in China is still in its infancy and exploration stage.So far,China has not yet formed a mature curriculum structure guided by the theory of advanced learning,and there are many textbooks whose knowledge arrangement is isolated and scattered.If more practical cases of advanced learning can be developed in the light of the reality of biology teaching in China,these cases can play a direct guiding role in teaching practice.This paper adopts the methods of literature research,case study,action research and interview research to study the book "Atlas of Science Literacy" in the United States.It combs the structure level of the core concept of "steady state and regulation"in the biology module of senior high school,draws up the learning progress map of this module,and gives some suggestions based on the learning progress map and the teaching practice during the practice period.Suggestions on advanced teaching of biology core concept learning in Senior High School.Overall,this paper draws the following conclusions:In fact,the book "Atlas of Science Literacy" is guided by the learning progressions theory.Each learning advanced map contains the following parts:scientific benchmark,grade range,connection line,association with other atlases in this atlas,and association with other atlases.The book follows the following principles in constructing learning advancement:following students' cognitive rules;allowing students to have wrong concepts and gradually correct them;the path of learning advancement is non-linear and cross-cutting;the basic facts to be understood by students have multiple dimensions;and learning advancement has strong interdisciplinary nature."Steady state and regulation" has only one core concept,that is,"the structure and function of the individual life adapt to each other,each structure coordinates and completes complex life activities together,and maintains steady state through a certain regulatory mechanism".This core concept is supported by 30 basic biological facts.When drawing a complete learning map,we need to install the concept map software as a tool,and then divide the 30 basic biological facts into grade level and knowledge dimension,the former as the vertical axis of learning map,the latter as the horizontal axis.After locating the facts and analyzing their logical connections,arrows are used to represent the thinking path of learning progress,and then the drawing of learning progress map can be completed.The strategies put forward through teaching practice are:teachers and researchers can design courses,develop textbooks,formulate teaching plans,carry out teaching evaluation and analysis relying on the advanced learning constructed by them.Learning advanced theory is still in the stage of exploring how to apply it in our country.The state should set up a scientific curriculum system and compile textbooks under the guidance of this theory;first-line teachers should take the initiative to undertake teaching and research responsibilities and develop more advanced learning cases;and national test formulators should develop evaluation systems that match the advanced learning curriculum system.I hope this paper will be helpful for teachers and students to understand the core concepts.
