Design,Development And Applied Research Of Natural Geography Unit Micro-Class In High School

With the continuous development of the implementation of the new curriculum reform and the deepening of information technology,the rise of the video in the form of a small micro class,it as a kind of new teaching method in improving the teaching efficiency and promote students' autonomous learning has a great help.Although there are many excellent geographical individual styles of the micro class,but the overall geographic micro micro class class quality uneven in quality,resulting in the utilization rate is not high,and the geographical knowledge is abstract and complex knowledge,more students are confused,the natural geographical single dispersed micro class is difficult to meet the students' learning system.Therefore,designing and developing the natural geography micro class accords with the student's cognitive level is an important way to solve the problem effectively,so that students can not only form the whole unit structure,but also learn independently according to their weaknesses.After reading a large number of micro course design development and Application on the basis of the relevant literature,combined with the high school geography textbooks,using the method of literature,questionnaire survey method,statistical analysis method to research the design and development of high school geography "unit micro course",and through the teaching practice and interview unit type micro geographic research application and the course evaluation.First,literature review is used to sort out the research background,research review and theoretical basis of unit micro class,and clarify relevant concepts of natural geography,micro and micro courses,series of micro lectures and unit micro courses.Secondly,through the questionnaire,investigation and analysis of teachers and students of geography class micro cognitive status,the widespread confusion of natural geography learning of senior high school students,there are micro class learning necessity;students love geography micro class features include 5-10 minutes long,micro class types,focus,speed faster,to explain the language is humorous and so on;the geography teachers generally understand the micro lesson,but the design and development of application of micro class less;teachers pay attention to micro class theme selection,the content of innovative design,exquisite courseware standardization degree;at the same time eager to develop geographical unit type micro class,but due to various factors,the development and application of design have difficulty.Then,according to the comparative analysis of some works of the three micro lesson websites,we found that geography micro class works are mainly based on natural geography,which are numerous,but not systematic,and the utilization rate is not high.Then,by using the method of literature and combining with the existing problems,it puts forward the principles and models of design and development,so as to prepare for the design and development of high-quality unitmicro courses.Next,according to the principle and mode of case studies on the chapter "the atmosphere on the earth",this chapter through the analysis of the textbook and curriculum standard,refinement of the 9 key knowledge of micro course design and development,including micro lesson plans,learning tasks,micro courseware and script design and editing,recording and post,and specific show the process of teaching practice.Finally,through the pre-test and post test experimental evaluation of teachers' and students' methods of practice,found that the application of micro teaching unit is superior to the traditional teaching,according to the feedback of reflection,should further improve the refinement of unit micro courses,enhance the ability to control the classroom teachers.
