Research On The Application Of Micro-classes In High School Biology Teaching

The introduction of information technology into the education circle has produced a variety of teaching methods,among which micro-course teaching is one of them.As a new type of teaching resource,micro-class is being used by more and more teachers and students.The research purpose of this paper is to explore the problems in the application of micro class in high school biology teaching and put forward Suggestions.Through the design of high school biology micro class case,and practice evaluation,make micro class better service for high school biology teaching,so as to improve the efficiency of high school students learning biology.This study mainly includes the following contents:Firstly,literature research is adopted to sort out the literature on micro-lessons,including the following aspects: defining the concept of micro-lessons;Distinguish the concepts of micro course,micro course and micro video;The characteristics and design principles of micro-class are sorted out.Secondly,classroom observation method,student questionnaire survey method and teacher interview method were used respectively to understand the current application status of microlecture in biology teaching in senior high school: 1.The application of microlecture is limited to classroom teaching;2.Micro class turns biology class into a "demonstration field";3.Some biology teachers are not good at micro-lesson making;4.Some biology teachers abuse micro-course resources.In view of the above problems,the author puts forward the following Suggestions for the application of micro-course in biology teaching in senior high school: 1.Micro-course teaching should promote students' personalized learning;2.Apply micro-lessons appropriately in group cooperation;3.Improve experimental teaching by applying micro-course in experimental class;4.The school provides training for teachers to make micro-lessons;5.The high school biology group established the resource bank of microlecture;6.Micro-course resources are published on the school website.Finally,according to the above Suggestions,two high school biology micro course cases are designed,and the cases are tested in practice,and the application effect is evaluated.The research shows that the application of micro class in group cooperative learning can effectively improve the learning efficiency of students,and the application of micro class after class can realize the personalized learning of students and meet the different needs of different students.
