Research On Situation Optimization Strategy Of High School Geography Multimedia Classroom Teaching

The 2017 new curriculum standard emphasizes the application of information technology.It believes that the development and application of information technology is a booster of geography teaching reform.It plays an important role in changing students' learning styles and teachers' teaching methods.Therefore,teaching informationization is the requirement of the times..Nowadays,the main form of teaching informationization classroom is multimedia teaching.Multimedia functions are complete,integrating sound,image,animation,etc.,using multimedia to create a high school geography classroom teaching situation,can vividly display geographic knowledge,make the boring classroom become lively,make students happy to learn,meet high school students The need for geography learning.However,there are still some outstanding problems and shortcomings in the creation of high school geography multimedia classroom teaching situation,such as single presentation form,shortage of situational material and low level of teachers' multimedia technology.Therefore,the research on this issue has strong practical significance.The thesis was studied by literature research method,case analysis method,statistical analysis method and interview method.Firstly,on the basis of reviewing the literature,the research topics,research background,research significance,research methods and ideas are determined.Secondly,the basic concepts and theoretical foundations are introduced,and the domestic and international research status of teaching situations,multimedia teaching and multimedia teaching situations are carried out.Summary;Thirdly,it summarizes the basic research viewpoints of high school geography multimedia classroom teaching situation,which is used as a guide to formulate the high school geography quality course viewing analysis dimension;fourth,conduct case analysis and create high school geography quality course multimedia teaching situation The reasons for the problems existed for interview analysis;fifth,the optimization strategy was proposed;finally,the main research conclusions,innovations,deficiencies and prospects of this paper were summarized.By summarizing the previous research viewpoints,the use of multimedia to create high school geography classroom teaching situation has the following characteristics:(1)intuitive,vivid and vivid,which is conducive to students' understanding;(2)strong dynamic,can reflect the process,effectively break through the teaching difficulties;(3)Various forms can stimulate students' interest in studying geography.The principles that need to be embodied in the use of multimedia to create high school geography classroom teaching situations are mainly scientific,authentic and exploratory.The strategy of using multimedia to create a high school geography classroom teaching situation is mainly to focus on the design of teaching problems and the use of life materials.On the basis of previous studies,combined with my experience in creating high school geography multimedia classroom teaching situations in educational internships,I have drawn up five dimensions of case analysis: classroom situation creation type,situation presentation form,multimedia context and teaching content relevance,The combination of multimedia context and blackboard,multimedia context and student response.Through the observation and analysis of the high school geography teaching video,it is found that:(1)the type of classroom situation creation is mainly multimedia context;(2)the presentation form of multimedia context is mostly picture,not enough;(3)the multimedia situation created by most teachers(3)The multimedia context created by most teachers is better combined with the blackboard;(5)Most students in the multimedia situation class are active.The 16 high school geography teachers were interviewed for the single-form situation of multimedia situations.The main reasons were the shortage of related resources,the heavy teaching tasks and the low level of teachers' multimedia technology.According to the results of case analysis,in order to further improve the creation of high school geography multimedia classroom teaching situation,the following optimization strategies are proposed:(1)focusing on the creation of multimedia contexts in the import process;(2)the presentation of multimedia contexts in the new course teaching sessions should be diversified;Multimedia context creation should be scientific and reasonable;(4)multimedia context should be combined with other forms of teaching.The main conclusions of the thesis are as follows:(1)In the high school geography quality class,the multimedia situation is the main type of situation creation;the characteristics of the created multimedia situation are mainly as follows: the presentation form is mainly picture,more monotonous;the multimedia situation created by most teachers The teaching content is more relevant;the blackboard book has an irreplaceable role;the students have a better overall response in the multimedia situation class.(2)Proposed an optimization strategy for the creation of high school geography multimedia classroom teachingThe paper mainly innovates in research perspectives and research methods.The innovation in the research perspective is as follows: by summarizing the previous research,the basic viewpoints of the high school geography multimedia classroom teaching situation creation are drawn,and the five dimensions of the viewing and analysis geography quality course are drawn up.The innovation of research methods is as follows: This paper mainly uses the case study method,taking the high school geography quality teaching video as the research object,and analyzing the characteristics and deficiencies of the high school geography multimedia classroom teaching situation creation.
