The Application Of Micro-course In The Teaching Of Physics After Junior High School

Micro-course is put forward against the background of the increasingly mature educational information.A teaching mode based on network short video.Micro-lessons "fragmented" the content of the course into 3-5 minutes of video.Let students watch at any time and anywhere.Moreover,the animation demonstration method that students like can enhance their interest in watching.Neither will it take up too much spare time of students.It will not add to the burden of students.Under the background of the new curriculum reform in our country,the level of educational information is constantly improving.The wide application of micro-lessons in the field of teaching is the performance of improving the level of education information.Micro-class can extend the classroom.It can help students expand their knowledge.It can strengthen the demonstration effect of the experiment and help teachers to realize the stratified teaching of students.Especially physics,a subject with strong combination of numbers and figures,video demonstration with explanation.It can provide students with more intuitive visual experience.It is convenient for students to understand and remember.As a junior high school physics teacher,in the application of micro-lessons,the author is also constantly exploring.Hope to produce high quality micro lessons.In order to understand the use of micro-class teaching in Chang Le No.1 middle school of talented persons' experimental school,understand the understanding of teachers and students on the design and development of micro-courses.The students' acceptance and demand for micro-teaching.And teachers' suggestions on micro-teaching.The author carried out a survey in Chang Le No.1 middle school.The survey results show that the school has already met the basic conditions of micro-class teaching.Teachers and classmates have higher acceptance and recognition of micro-classes.For the application of micro-lessons,teachers are most concerned about the teaching effect and how to design and make micro-lessons.But due to lack of experience,problems such as insufficient technical and equipment support.Thereare still many difficulties in the use of micro-lessons.Secondly,the junior middle school students surveyed have a higher understanding of micro-lessons even higher than teachers.Students understand that part of micro lessons is displayed by classroom teachers.The other part is to learn about micro-lessons through the network.Judging from the current situation.The students in this school prefer micro-class as a teaching form.Especially like video demonstration and animation demonstration.Finally,the frequencies of micro-classes used in the second and third grade of junior middle school are higher.Through the use of micro-classes,students' self-study consciousness has been improved.On the basis of the investigation,the author makes an attempt to design a micro-course with the topic of "Review and Consolidation of Mechanical Motion Theme".To accumulate experience for the production of other micro-lessons in the future.After the micro lesson made by the author was put into use,in order to verify the effect of micro teaching.After a quarter,the author compares the two classes that have received micro teaching with those that have not.It is found that the grade of the class receiving micro-class teaching has been greatly improved.And the overall improvement of students at different levels.In order to further understand the students' feelings of accepting micro teaching,the author made a second survey of the students who had received micro teaching.It is found that micro-classes enhance students' interest in learning physics.It also improves students' physics learning ability and experimental operation ability.Through investigation and comparison,the feasibility and validity of micro-lesson in physics extracurricular teaching in junior high school are verified.In the future,the author should continue to learn,improve the ability of micro-lesson production,and produce more useful and interesting micro-lesson videos for students.
