The Construction And Practice Of Core Concepts In High School Biology Teaching

Biology is a natural science that studies the phenomena of life and its discipline of activity.It contains numerous biological concepts and the biological facts that underpin them.In biology teaching,teachers often pay attention to how to make students remember a large amount of biological knowledge,and this knowledge is generally scattered,and will be gradually forgotten with the learning of new knowledge,so teachers must change their teaching methods,Find ways to make these scattered knowledge in the student's brain as a whole.With the introduction of core concepts,this theory provides a theoretical basis for the change of teaching methods.More and more people are aware of the importance of core concept teaching.In recent years,educators have done a lot of research in this area,and the teaching of core concepts is still in an exploratory stage.n the 2017 edition of the new biology course standard emphasizing the significance of the core concepts in biology teaching again,but the present teaching on the core concept of attention is not enough.Based on the above situation,this paper proposes the topic of "construction and research of core concepts in biology teaching in senior high school".This article is mainly from the perspective of constructing core concepts,identifying core concepts in textbooks,investigating students' mastery of core concepts in biology,finding problems in core concept teaching at present,proposing systematic teaching strategies,and conducting corresponding instructional design.It also conducts practical research on core concept teaching through heterogeneous methods in the same class,and strives to summarize effective and feasible core concept construction methods to provide reference for the majority of front-line teachers and education researchers.Through research,the conclusions are:(1)teaching of basing on core concepts can better grasp the teaching difficulties;(2)teaching of basing on core concepts can help teachers make better use of teaching materials;(3)teaching of basing on core concepts can help reduce students' memory burden;(4)Teaching of basing on core concept construction can help students establish a disciplinary framework system.
