The Study On The Application Of Micro Lesson And Guide Case In Senior High School Electromagnetism Teaching

The 21 st century is the era of information technology.The integration of education and information technology is the inevitable trend of future development with the development and popularization of information technology.Micro course that has the characteristics of “short and pithy” is gradually applied in the field of education as the product of information technology and emerging educational resources.Guide case has been widely used in secondary schools as a teaching resource and has a certain supporting role in secondary school teaching.Micro course and guide case try to realize the transformation of education from "teaching center" to "learning center",reflecting the new curriculum concept of "student as the main body";Therefore,the micro course has same value with guide case.At the same time,micro course can not completely replace the existing teaching model as a new resource because of its imperfect relevant theoretical and practical research.Therefore,the integration of micro-course and guide case can complement each other.It can assist the physics teaching better and be a new foothold for the micro course in secondary school teaching.Thesis researches the application of micro lesson and guide case in electromagnetism teaching.The author finds the research background,meaning and theoretical basis through reading literature.The author knows the learning status quo of electromagnetism and students' demand for information technology through questionnaire survey.The author obtains some conclusions: micro course can be used to make up for the lack of students' feeling of electromagnetic knowledge;micro course can be used to answer students' questions when teachers can not solve students' problems one by one;The advantage of micro course and guide case can complement each other,which can be integrally used.The author analyses the feasibility and necessity of the integrating of micro course and guide case,and clears the integration model of "micro course for the point,guide case for the face".And The author puts forward four strategies of the integration of micro course and guide case,which is applied to electromagnetism teaching: firstly,Creating situation and enhancing perceptual knowledge;secondly,combing static and dynamic,breaking through the difficulties;thirdly,constructing the knowledge system of electromagnetism;fourthly,filling in the insufficient of studying,correcting and reflecting.Around these four strategies,the author designs examples for electromagnetism concept classes,regular classes,and experimental classes.Finally,the author reflects on special teaching of "the live particles in the magnetic field movement" and improves the teaching design.The improvement under the idea of integration of micro course and guide case is applied to one-on-one counseling,which has a good result.
