Application Study Of The Core Concept Teaching Strategy Of High School Biology "Homeostasis And Environment" Module

The high school biology curriculum standards of the 2003 edition advocate students a deep understanding of the core concept of biology into the real life,and the curriculum standard of the 2017 edition also mentioned to focus on the content of the course concept,do "fewer but better",leading the students to fully understand and apply key concepts,thus improving the students' biology core literacy.In recent years,the workers and college education researchers who are engaged in first line of educational high school biology teaching pay more and more attention to the high school biology teaching and research about the core concepts,And the author during the master plan to recognize through access to relevant data,found that foreign research about the core concept of teaching has been basically mature,the relevant domestic core concepts teaching theory research is also gradually perfect,but for the core concept of biology teaching in China is relatively lack of practical research,especially in the high school biology required three the steady state and the environment more modules of the core concepts and abstract,is the emphasis and difficulty in teaching,Therefore,the integrated use of literature,teaching material analysis,investigation method,action research method,empirical method and statistical analysis methods such as this module around the core concepts of the teaching practice for the systematic research.First of all,the author seriously study of literature,the system of finishing the research achievements of predecessors,carefully study the teaching material and curriculum,on the basis of the corresponding interviews and questionnaire survey combed the high school biology required three "steady state and the environment" of the core concepts of the module and the general concept.Then,the author will be the core concept of teaching theory into the actual biological teaching practice,according to their teaching huai marina high school grade two regular class as the research object,and set up the control experiment,the experimental classes for a term of the core concepts of teaching practice and study and practice,respectively tease out teaching materials in the history of science,model,resources,exploration activities,such as resources,to explore the cooperation,creating situation,the history of science,system analysis and model strategy analysis,the teaching effect shows the different teaching strategies of some teaching cases and part of the student work,To put forwardreasonable Suggestions and Suggestions on the core concept teaching strategies.Finally,the author through the questionnaire survey,comparison of the achievement,data analysis and other methods of this module is the core concept of teaching effect are analyzed,the results show that the experimental classes in the implementation of the core concepts teaching strategies after a period of time,students interest in learning and innovation ability of biological studies and academic performance and so on has the obvious promotion,teaching effect is remarkable.In conclusion,during the study the author proposes that some core concepts need to be modified in the process of teaching,such as the core concept of screening,selection of the core concept of teaching strategies,related strategy which problems need to be paid attention to.However,the study is only in view of the high school biology required three "steady state and the environment" module for more than a year of research and application of the core concepts teaching,research scope and time limitation of this study is limited.Therefore,the author will continue to work hard in the future to finish other module core concept of high school biology teaching practice and study,to optimize the core concept of high school biology teaching practice to provide more reference and suggestions.
