The Development And Utilization Of Biological Life-based Case Teaching Resources In Junior High School

Under the guidance of the curriculum standard "paying attention to the connection with real life",the implementation of life-based case teaching is one of the effective ways to change the traditional biological teaching mode and realize this concept.Educators use life-based case teaching methods in the teaching process,rationally introduce living materials to create a life-oriented teaching situation,and start from the student experience,transform the students' pre-scientific concepts,that is,the non-essential knowledge formed by experience accumulation into related the concept of biological sciences,which helps students to deepen their understanding of the nature of biological knowledge and stimulate the enthusiasm and initiative of learning.At the same time,the use of life-based case teaching is of great significance to improve students' ability to analyze and solve problems and promote the development of all aspects of quality.This requires teachers to dig deeper into the life-oriented content of the textbooks,learn to rationally integrate and utilize teaching resources,create effective teaching situations,and improve the efficiency of biology teaching.This paper takes the teaching content of the seventh grade of the human education edition biology as the carrier,and combines the specific content requirements of the compulsory education biology curriculum standard(2011 edition)to develop and utilize the life-time case teaching resources.Firstly,the literature research method is used to sort out the research status at home and abroad,to clarify the connotation of related concepts,and to discuss the theoretical basis of life-based case teaching;Secondly,it analyzes the results of teacher interviews,to propose development principles,to analyze the teaching materials in combination with curriculum standards,and to use data collection.The law combines its own practice case to develop and integrate case resources,and attempts to divide the case into imported cases,generative cases and summary cases according to its functions,and summarizes the resources contained in the developed life cases;Develop methods and principles for the use of case resources,and use case analysis to analyze and reflect on specific implementation cases.Finally,use questionnaires and interviews to understand the use of case resources for development,and use data statistics to analyze the implementation effect of case teaching resources in daily life.The research results show that the use of life-based case teaching resources for teaching can create a good learning atmosphere,stimulate student's interest and initiative in learning,expand students' horizons,help students understand and explain some phenomena in life,and improve students' ability to solve practical problems in life.At the same time,it can help students gradually develop good living habits and healthy living attitudes.However,the development of case teaching resources is a long-term,systematic project.This study is only for the preliminary study of the life-time case teaching of junior high school biology teachers.It provides some references to the case resources and principles and methods for developing and utilizing case resources.In the future,more researchers will be able to participate in the development of case resources and promote the development and utilization of case teaching resources.
