| In January 2018,the Ministry of Education clearly put forward core literacy,and also proposed that the implementation of core literacy should take the concept of discipline as the core.The proposal of subject core literacy calls for unit teaching.The special feature of unit teaching is that it crosses the boundary of class hours and combines content related to teaching theme into a teaching unit from the perspective of discipline integration.Unit teaching is an important teaching mode under the new curriculum background.It helps students to understand geography knowledge comprehensively and systematically and cultivate geographical thinking by integrating teaching content and constructing knowledge framework.However,in the process of integration,there are various ways to integrate unit content according to different teaching purposes.In view of this,this paper tries to carry out the teaching case study from the unit teaching design and unit teaching classroom,in order to provide reference and reference for front-line geography teachers to carry out unit teaching.First,under the guidance of system theory and constructivism learning theory,this paper expounds the research background and significance,combs the domestic and foreign research status of unit teaching and lesson study,defines the research purpose and content,chooses the research method and determines the technical route.Secondly,literature analysis is used to analyze the current situation of 45 high school geography unit instructional designs from six dimensions: unit design ideas,unit teaching types,unit teaching contents,unit teaching main line,unit teaching objectives and unit teaching evaluation.Based on the research of unit teaching design,three front-line geography teachers were interviewed by the interview method to understand their understanding of the current unit teaching.Using the classroom observation method and relying on the LICC model of classroom observation,this paper selects the same class heterogeneous unit classroom teaching lesson "sea-air interaction" to analyze and study from two dimensions of teachers’ teaching behavior and students’ learning behavior.Thirdly,combined with the analysis results of the current situation of geography unit teaching design in high school,the analysis results of the interview survey of high school geography teachers,the analysis results of the observation and analysis results of high school geography unit teaching,the implementation strategy of high school geography unit teaching is proposed,including the basic principles of unit teaching implementation,the strategy of unit teaching design writing and the implementation strategy of unit teaching class.Finally,combined with the implementation strategy of unit teaching and taking "ocean water" as the core concept,I designed and wrote the teaching case of ability unit with the theme of "Entering the strange Peru,exploring the mysterious ocean".The research findings are as follows:(1)From the analysis of the current situation of teaching design of high school geography units.the unit design ideas are mainly conventional ones,The type of unit is mainly natural unit.Unit content is mainly compulsory modules,The main line of the unit is the main line of knowledge,Unit teaching objectives need to be perfected,The combination of multiple unit teaching evaluation methods.In general,there are few unit teaching researches on geography in senior high school.(2)From the interview survey analysis of high school geography teachers.front-line geography teachers believe that unit teaching mode has advantages,but there are still some difficulties to be overcome in a long period of time.Combined with the current situation of geography unit teaching design in high school and the suggestions of first-line geography teachers’ interviews,unit teaching can be studied from the following three directions: pay more attention to the thinking mode of reverse teaching design;Try more ability unit and concept unit teaching;Try to teach more by using the main lines of situation,problem and task.(3)From the observation and analysis of high school geography unit teaching classroom.it is found that the key point of unit classroom teaching is to teach geography knowledge under the guidance of unit consciousness;The main line of teaching clearly runs through the unit class;Unit goals help construct meaning.Through the observation and research of unit teaching design and unit teaching classroom,it can not only enrich the theoretical research of unit teaching,but also provide some reference and enlightenment for middle school geography teaching practice and unit teaching case study. |
