| According to the Training Targets of New Curriculum on The Basic Education Curriculum Reform Outline(trial)issued by Ministry of Education in 2001,the students should be cultivated to have basic knowledge,basic skills and methods that are suitable for life‐long learning.Moreover,the Specific Targets of Basic Education Curriculum Reform mentions that more attention should be paid to students ’learning interests and experiences,their abilities to search for and deal with information,gain new knowledge,analyze and solve problems,and communicate and cooperate.Facing the requirements of new curriculum standard and teaching practice,physics teachers should not only teach students the knowledge on textbooks,but also help students to feel the pleasure of study and cultivate their enthusiasm to study.During this process,the teaching methods,ways and means are for one final target‐‐to teach students how to study.On this occasion,how can we draw students ’ attention? How to make profound theories easier and easy questions more interesting? Is itpossible to employ some time pockets to study in a short period? Is it possible to make study more interesting? Against that backdrop,the micro‐lecture was born.Micro‐lecture is a kind of short‐time teaching video on the basis of certain small knowledge point.It is featured by being easily gained,short time,highlighted content and key points,clearly explaining and stressing interests.Micro‐lecture is short but terse.Every topic and every key point is precisely designed for students ’difficult questions,making micro‐Lecture suitable for students to learn on their own.The impacts posed by micro‐lecture on teaching at senior high schools cannot be ignored,either.This paper further demonstrates and researches the teaching methods of micro‐lecture on the aspects of task theory and practical teaching.The first chapter of this paper is the introduction,analyzes the requirements of New Curriculum Standard to physics teaching,expounds this task ’ s research background,research significance,and present situation of domestic research,and puts forward research questions.The second chapter is the theoretical basis of research.The necessities of micro‐lecture is discussed from constructivism learning theory,humanism educational values and self‐teaching theories.The third chapter surveys the status quo of physics micro‐lecture teaching at four provincial‐level demonstration senior high schools in Guiyang city.The investigation method,documentary method and analysis method are employed to investigate and survey the attitudes and opinions of senior high school teachers and students.The fourth chapter concludes the approaches to produce and edit mini‐lecture videos,sorts out the design key points of physics micro‐lecture at senior high schools and exhibits some cases according to micro‐lecture design of various class types.The fifth chapter researches the impact posed by micro‐lecture on physics learning practically at senior high schools.It chooses curvilinear motion of PEP edition of compulsory education 2,uses micro‐lecture design principles of the fourth chapter in this paper,adopts mini‐lecture in physics teaching at senior high schools.Moreover,it carries out practical research on the Sixth Middle School of Guiyang County and analyzes the results.At last,it concludes that properly use micro‐lecture in teaching is positively related to improve students ’ academic performance.The sixth chapter sorts out the outcomes and shortcomings of this paper.This paper surveys and researches the implementing situation of senior high school micro‐lecture at four provincial‐level demonstration senior high schools in Guiyang city and the opinions of senior high school teachers toward physics micro‐lectures.Moreover,it puts forward some suggestions toward how to efficiently use micro‐lectures to improve senior high school physics teaching.This paper provides reference to how to apply and promote micro‐lecture in senior high school physics teaching. |
