Strategy Research Of Micro Video Application In Junior High School Physics Family Experiment

Over the period of compulsory education,the trend of educational reform is to change the students from the passive recipients of knowledge into the active researchers of knowledge and pays attention to the exploration of learning content."The junior middle school physics new curriculum standard" stressed that we should make life more physical and make the physical return to society,advocating diversified teaching form of experimental teaching,paying more attention to inquiry oriented teaching mode and promoting the use of information technology in physics teaching and diversified and procedural evaluation and feedback.At the same time,it is necessary to actively carry out extracurricular experiments,and the family experiment as an important supplement to classroom experiments and physical knowledge should be paid more attention.But how to guide students to carry out family experiments,count the students' participation and the actual effect of the experiment for teachers are confused.With the rapid development of information technology and the continuous upgrading of mobile intelligent terminals,the application of micro video is popular in the teaching field.Thus,with the help of the network,the mobile intelligent terminals to learn the fragmentation of content at any time and anywhere becomes more and more popular.The author analyzes and summarizes the current situation of physical family experiments and the application of micro video in teaching through the method of literature research.At the same time,establishing the starting point and the perspective of the study through the analysis of related cases in which recording the micro vedio of learning process can improve the learning effect of the students.The author attempts to make the parents record the student's family experimental process into a micro video,which can not only effectively urge students to complete the experiment,the most important thing is to provide a true,complete and effective basis for teachers to examine and evaluate students' family experiments.It is convenient for the teachers to find out the different problems of different students,and to provide targeted guidance and correction,so as to promote the comprehensive ability of students.The main research questions are: teachers how to select the suitable family experimental material and develop experimental program;teachers how to design experimental tasks and guide the students' independent family experiments based on micro video recording from multiple aspects;how the teachers give evaluation and feedback to students' families experiments.The author processes three rounds of iteration incremental study,which based on research by design method as the main line and selected the Class 1,Grade eight from a school as experimental object.After each iteration,the focus user interviews are conducted in order to improve and perfect the preliminary design.Finally,based on the preliminary design,the author will increase the experimental micro video of the teacher,the example of the paper version of the experimental report guidance and student evaluation links.At the end of the study,all the students are investigated by questionnaire,and interviews with individual parents are conducted.Finally,the data collected are analysed by SPAA and other statistics software.The results show that this new type of physical family experiment has been recognized by teachers,parents and students.What's more,it improves the students' ability of comprehensive experiment,and have a positive impact on teachers and parents.Finally,the paper puts forward the application strategy of micro video in the junior high school physics family experiment from the experiment,before and after the experiment,in order to provide reference for the majority of educators.
