| "Internet plus education" has brought about the impetus to reform and profound influence for both the teaching methods of physics teachers and learning methods of students in senior high school.In the context of core literacy,we should pay attention to the full use of modern educational ideas and teaching methods in education and teaching,and strengthen the cultivation and improvement of students’ core literacy within a certain discipline.Physics is a basic subject in the field of natural science,which studies the basic structure,interaction and motion law of natural matter.As one of the required subjects for senior high school student,many students have devoted a lot of energy to this subject,but they can not achieve desired results,resulting in the loss of confidence and interest in learning,and even weariness of learning.As the product of modern information technology advancing with the times in the field of education,micro lecture is an important auxiliary teaching mode of physics.High quality micro classroom can not only stimulate students’ interest in learning and attract their attention,but also create a good learning situation for students,give full play to students’ subjective initiative,make students become the main body of physics classroom and improve learning efficiency.In recent years,micro lecture has been paid more and more attention by teachers and students.Primary and secondary schools all over the country are actively carrying out the construction of micro class resources.The preliminary development of micro lecture in the whole country has received strong response from teachers,students and educators.However,there is still a lack of detailed and in-depth excavation in the subject education of micro course combined with basic education,and the relevant research needs to be improved.In this paper,the author will depend on his own teaching practice to explore the design,creation and practical application of micro lecture suitable for high school physics teaching,in order to obtain a set of microlecture auxiliary teaching method suitable for high school physics,aiming to make a beneficial attempt for the reform of high school physics curriculum in the new era.The main research content of this paper is: first of all,through the student questionnaire and teacher interviews to understand the application of micro lecture in high school physics teaching;Second,the application mode and sharing mode of micro lecture are explored through practical teaching of micro lecture in high school physics subject for two years;Finally,through studying three specific cases to explore the design and creation of micro lecture and prove the positive role of micro lecture in promoting high school physics teaching through analysing students’ performance in classroom and synchronous practice.This paper mainly adopts the comparative method.Two classes with similar level of students were selected as the research objects and divided into the control group and the experimental group.The control group was given traditional physics teaching.The students in the experimental group used the micro lecture.The micro lecture was widely used in autonomous preview,deepening of teaching key and difficult points,induction and summary of typical exercises,extracurricular extension,weekend and holiday review comparing the results of the two monthly examinations,and the performance of the students’ in these two classes,highlighting the advantages of micro class in physics teaching.The conclusion of this paper is summarized as follows: the use of micro lecture in high school physics teaching can stimulate students’ interest in learning,intuitively show the teaching objectives,improve the efficiency of classroom learning,help teachers explain knowledge,help students review,and improve teachers’ professional level.The innovation of this paper lies in the combination of micro lecture and the "three links and six steps" learning method,which is a teaching mode of the curriculum reform in author’s school,that is,guidance,self-study,communication,summary,consolidation and promotion.The micro lecture is fully applied in all aspects of classroom teaching,providing a practical platform for students’ self-learning after class,and taking advantage of students’ weekends and holidays to help students solve their learning problems.Finally,it can guide students to maketheir own micro lecture.Of course,there are still some problems that can not be solved properly.First,some students have poor learning habits or even weariness of learning due to their families or previous learning experiences.For these students,how to attract them in micro classroom is a problem.Second,individual students have poor self-discipline.How can they be effectively supervised using the use of mobile phones for micro class learning instead of,playing games and reading novels.Third,some students lack the ability of autonomous learning.In the face of abundant micro lecture resources,how they choose and use them should be taken into consideration.With micro lecture assisting physics teaching,the learning ability,learning interest and learning achievements of the experimental class have made obvious progress,basically reaching the expectations of the experiment.Therefore,it is feasible to introduce micro class into physics teaching in senior high school,and it is worth promoting.I hope this study can provide reference for senior high school physics teachers,produce demonstration and radiation effect,and provide practical materials for the theoretical construction and practical research of micro lecture. |
