| With the rapid development of information technology,people’s lives are affected by the Internet all the time,and various mobile facilities have had an impact on the way of work,especially learning.The new curriculum standards for high school geography also put forward the requirements of deepening the application of information technology,creating a more vivid and intuitive geography teaching environment,and using information technology to enhance the personalization of geography learning.The outstanding "short and concise" characteristics of micro-courses are suitable for the needs of geography teaching in the context of information technology,especially in the physical geography that is more abstract and general,and is not easy for students to understand,and the majority of teachers are more inclined to choose the difficulties of physical geography teaching as the topic of micro-lessons.Therefore,based on the current situation of high school physical geography micro-course design,the optimization strategy of micro-course design is proposed to have certain practical research significance.This paper mainly conducts research through literature research method,case analysis method,observation method and questionnaire survey method.First of all,through the literature analysis method,collect relevant literature and read it to determine the research background and research significance of the paper;Secondly,the literature is analyzed,and the research status of micro-course,micro-course design,and physical geography micro-course design at home and abroad is summarized,and on this basis,the literature is collected to establish the observation dimension of micro-course;Then,the cases are selected for microlesson observation and analysis,and combined with the data of the teacher’s questionnaire survey,the advantages and disadvantages in the design of physical geography micro-courses are summarized;Finally,based on the above content,the optimization strategy of physical geography micro-lesson design is proposed,and the case design is carried out,in order to bring useful reference for front-line teachers to design physical geography micro-lessons.Through the observation of micro-lesson cases and questionnaire surveys,it is found that there are some good aspects in the design of physical geography micro-courses:(1)In terms of topic selection,it is mainly concentrated on the difficulties of physical geography teaching,and the title design of micro-courses is concise and prominent;(2)In terms of content organization,the vast majority of micro-courses have clear logic,advance with problem chains,and progress layer by layer;(3)In terms of media design,most of the micro-lesson teachers have clear and fluent voice input,clear text,and clear charts and animations.At the same time,there are some deficiencies:(1)Some teachers have biased cognition of micro-lessons,and the integrity of micro-lesson resources is lacking;(2)Teachers design fewer micro-lessons on their own;(3)Most teachers fail to demonstrate teaching objectives;(4)There is no teacher-student interaction setting in most micro-lessons;(5)Most of the micro-lessons are single in form and lack of interest.According to the theoretical basis of micro-course design and the current situation of physical geography micro-course design,the following optimization strategies are proposed:(1)The setting of teaching objectives should be targeted: the setting of teaching objectives should be based on curriculum standards;Refine the teaching objectives according to the selection of micro-course topics;Testable;(2)Increase the creation of situations,improve the fun of micro-lessons: increase the creation of life-oriented situations;Increase the creation of experimental exploration scenarios;(3)Improve the micro-lesson link and improve the effectiveness of the micro-lesson: increase the introduction and after-class summary;Set up interactive sessions;(4)Teachers themselves should strengthen the learning of theoretical knowledge of micro-lessons,and improve language design ability.The innovation of this paper lies in the innovation of the research perspective.Based on the relevant theories of micro-lesson design and the main views put forward by relevant scholars,observe and analyze the existing natural geography micro-lesson videos on the micro-lesson platform,summarize the advantages and disadvantages of these micro-lesson designs,and propose corresponding optimization strategies for existing problems,so as to provide front-line teachers with useful references and references for micro-lesson design,and promote the further implementation of micro-lessons in practice. |
