Study On The Development Of Micro-lecture Of Physical Geography Experiments In Senior High School

With the development of education informatization and internet technology,the traditional teaching model cannot meet learning needs of students.Micro-curriculum has gradually become a new form of learning.However,at present,the number of geography micro-lecture in secondary schools is still limited.Micro-curriculum content is still dominated by lecture,which has not changed the impact of traditional teaching.This study starts with geographic experiments and attempts to incorporate geography experiments into micro-lecture.It explores the development strategies of the micro-lecture of natural geography experiments in high schools to enrich teaching resources,inspire students' interest in geography study,and enhance their practical and thinking skills.It also provides some inspiration and suggestions for the front-line geography educators to carry out relevant research and micro-curricular development.This research mainly uses the literature method and the educational experiment method,consults and studies a large number of predecessor research literature and examples of geography micro-lecture,and understands the relevant theories and practical experiences of the development of micro-lecture.At the beginning of the development,the author combed the relevant contents of the physical geography experiment in high schools according to the “Ordinary High School Geography Curriculum Standards(Experiment)” and the PEP geography textbooks,and then combined the author's actual situation with select topics,design and production of three steps,carrying out the development of micro-classes.Finally,the feasibility and effectiveness of the micro-curriculum case were verified through teaching implementation and evaluation reflection.The evaluation part adopts the method of students' feedback,teacher's reflection and peer teacher grading system according to the evaluation index system.Through the topic selection,design,development and implementation evaluation of the micro-curriculum,this study has come up with strategies for create micro-lecture for physical geography experiments in high schools:(1)Development process,which mainly includes topic choice,experimental design,instructional design,PPT production,experimental operation and recording,courseware recording and video synthesis.(2)Strategy for selecting topics: guided by the curriculum standards,refer to the relevant requirements and activity suggestions of the curriculum standards to find the development content and topics more scientifically and systematically;based on the contents of the teaching materials,decide the difficult and difficult points of the teaching materials,and knowledge points to develop micro-curriculum resources can more effectively highlight the key points and break through the difficulties;comprehensive consideration of "school conditions",academic conditions and teachers' ability and conditions and other factors,select the most proper theme for development.(3)Design strategy: precise target design,with the curriculum as a guide,targeted teaching objectives for individual knowledge;applicable content design,complete micro-content design combined with micro lessons',experiments' and students' characteristics.(4)Production strategy: the experimental operation,at first,must be regulated,and then make sure safety;produce courseware follows a concise and clear principle;the recording of the video should simple,beautiful,smooth and natural.
