Practical Research On The Development Of Junior High School Students' Concept Of Life Based On Concept Teaching

The main research direction of this thesis is to develop the life concept of junior high school students based on concept teaching.This thesis defines the concept of life concept and concept teaching,constructs a conceptual knowledge framework for part of the extended dimension of life concept,and develops a teaching design framework based on the four steps of concept teaching.Afterwards,classroom teaching practice and comprehensive curriculum practice are carried out,and the effectiveness of conceptual teaching in developing junior high school students' concept of life is tested through summative performance analysis,process evaluation,interview analysis and classroom observation.The main contributions are as follows:The concept definition of life concept and concept teaching,combined with the conceptual knowledge framework of each extension dimension of the corresponding life concept,puts forward a teaching example for the development of junior high school students' concept of life promotion based on concept teaching strategies,which includes integrated practical teaching developed the "winter lettuce cultivation projects",and the classroom teaching focus on "Evolution and Adaptation view","heredity and variation view","view of matter and energy" in the new lesson.Further exploration of the new path to develop students' concept of life also provides an important new perspective for in-depth research and development of junior high school students' concept of life and concept teaching.The application of concept teaching is feasible in the teaching of the development of the life concept of junior high school students.In the teaching process,by providing real problem scenarios,based on the conceptual framework,the core problems pointing to the core concepts are proposed,the core problems are transformed into important problems step by step,and then the teaching content of this section is transformed into general problems to promote the generation of students' concepts in the class,and develop students' higher-order thinking.Taking the core concepts pointed to by this unit as the framework,presenting the real situation,starting from the bottom up from the factual knowledge,guiding students to build the relationship between the concepts in depth,which can effectively drive the students to develop the concept of life.After applying the concept of life concept and the strategy of concept teaching to guide the curriculum practice plan and the implementation of the teaching process,the relevant process assessment papers and summative assessment papers for detecting the improvement of the life concept of junior high school students were produced.In the examination of students' academic level,we pay attention to creating a real situational atmosphere,and implementing the requirements of the concept of life so that students can use the learned concepts to solve real problems.The data analysis of academic level shows that the strategy of developing students' concept of life based on concept teaching is able to effectively improve students' academic performance,and then has a certain positive impact on the development of students' concept of life.Through interview analysis and classroom observation,it is found that different forms of concept teaching can help students continue to exert their subjective initiative and enhance their interest in learning.Finally,we summarize and reflect on the research conclusions.In the practice of developing junior high school students' concept of life based on concept teaching,due to the limitations of personal ability and time and region,the sample size of teaching cases is small,and further research is needed.
