Research On The Application Of Micro-Video Case Teaching In Biology Experiment In Junior Middle School

With the continuous progress of information technology in our country,more and more modern equipment has been applied ? integrate into daily teaching.Diversified teaching resources have been integrated into teaching,enriching teaching content,broadening students ' horizons,and enabling students to better grasp biological knowledge and experimental skills.However,how to make better use of modern information teaching resources,stimulate students' learning motivation,let students master more knowledge and improve efficiency in the biology experiment classroom is the problem faced by biology teachers.The introduction of micro-video into biology experiment teaching is a way to solve the problem.The research on the recording and application of micro-video in biology experiment teaching is carried out according to the corresponding teaching contents,in order to provide reference for the application of micro-video in biology experiment teaching.In this paper,the background,methods,theoretical basis,design,application,results and conclusions of the research are discussed in detail in seven parts.The emphasis is on the recording of micro-video based on the principles of enlightenment,timeliness and guidance,which meet the students' cognitive level and meet the requirements of teaching content,and with the experimental equipment available in our school.The application of micro-video in experimental teaching enables students to actively participate in the construction of knowledge in the context of video,enhance their interest in learning,experience and master biological experimental knowledge and operational skills,so as to improve students' biological literacy and academic performance.Five videos recorded by ourselves are applied to the corresponding biology experiment course in the experimental class.The results show that this teaching method is feasible and has been approved by students and teachers.At the same time,the students' test scores on these five experiments have been significantly improved compared with those of the control class.It improves teachers' teaching efficiency and students' learning efficiency and thinking efficiency.It shows that the application of micro-video in junior high school biology experiment is of positive reference significance.The application of micro-video in experimental teaching can provide reference forcolleagues of our school and other schools.
