Research On Subject Key Competencies And Case Design Of Education And Teaching Based On Compulsory Biology Textbooks For Senior High School

Senior high school biology is a comprehensive subject with higher requirements for students and teachers,The traditional teaching model with knowledge goal as the main objective is too indoctrinated.In order to better promote students' all-round development,the new curriculum standard are based on key competency,enhance students' disciplinary ability from the four perspectives of life concept,scientific thinking,scientific inquiry and social responsibility.and concentrates on incarnating the educational value of biology department.How to correctly cultivate students' key competency has become a major task for middle school teachers.On the basis of the existing key competency research,in December 2016-2018,the literature research method,content analysis method,education investigation method and case enumeration method were used to conduct in-depth study on compulsory textbooks.Integrate the design ideas and content structure of the textbooks,and study the concrete manifestation of key competency from the main texts,columns,exercises,and experiments,explore the internal connections of different literacy in the textbooks and build models,and discover the value of teaching materials to cultivate students' key competency.Dynamic analysis of the key competency status of teachers and students in various middle schools,discovering existing problems,proposing feasible solutions,developing practice cases for cultivating students' key competency,and implementing application programs.The results of the study are as follows: 1)the embodiment of key competency in textbooks is extensive and comprehensive,creating a good cultivation atmosphere in the learning of body knowledge;2)the auxiliary function columns are rich and diverse,and the expression of scientific thinking is particularly prominent;3)the experiment is based on the concept of life,which plays an important role in improving scientific thinking and scientific inquiry ability;4)after-school exercise testing;At the same time,the key competency of the subject is permeated and students are guided to use biological knowledge skillfully to solve practical problems.The analysis shows that 1)key competency is a complementary and unified whole,and the same knowledge point can be presented from different perspectives,focusing on the cultivation of different literacy 2)Different knowledge points can be used as the cultivation material of the same literacy.In terms of the current situation of key competency training,the survey found that 1)students' understanding and assimilation level of key competency is low 2)teachers are limited by many factors both in and out of class,and the degree of training is not high.In view of the above analysis and investigation,this paper studies and compiles the key competency-based classroom teaching records in three compulsory textbooks,combines examination propositions and practicalactivities,and establishes reasonable and effective cases of cultivating students' key competency from multiple perspectives,so as to improve the feasibility reference value.Based on two years' teaching practice exploration,the research is carried out from the perspective of complete textbook structure and content,enriching the theoretical support of biology textbook for core literacy cultivation;forming a large number of visual and quantitative charts and knowledge points embodied in core literacy,providing convenient information selection for teachers;building a core literacy model of discipline to help teachers and students understand its connotation and Association Departments: The use of classroom infiltration teaching model,with textbooks as direct training materials,has better solved the contradiction between core literacy training and daily teaching tasks;and put forward reasonable suggestions for curriculum teaching,examination proposition and career development.Follow-up will continue to analyze the key competency of elective textbooks,explore the biology teaching strategies of liberal arts students,further study the application and evaluation of key competency,constantly expand and improve effective teaching cases,and develop key competency school-based curriculum with local characteristics.
