The Development And Application Of Experiential Micro-course In Middle School Biology Teaching

This article is based on the author's combination of experiential teaching theory,and guided by the teaching objectives of "Ordinary Senior High School Biology Curriculum Standards".It uses rich video technology to design and develop a more interactive and better-feeling micro lesson.Because of the easy operation,the more important part is to let more teachers master the technology and even let the students understand the production methods of micro-teaching.In this study,four classes in the second year of senior high school students from the Hong'an Yucai School in Huanggang City were selected as the research subjects.The following experiments were conducted: First,the use of well-produced micro-classes in the classroom was divided into abstract process content,inquiry content,and experimentation.On the sexual content,they respectively carried out teaching practice;Second,The introduction of technology to students,let students try to design and produce micro-curriculum autonomously and observe and investigate students' learning status.During the four-month teaching practice,learners were surveyed and interviewed and found:The statistical analysis of learner test scores found that the use of experiential micro-teaching classes in the pre-test and post-test results showed a certain degree of decline,which has a certain relationship with the test difficulty of the academic level test;The average level,high score rate,and pass rate of the teaching group in the experiential micro-teaching class and the teaching class without using the experiential micro class were much higher than those in the control group;the survey of the immersion experience in the student learning process was conducted through the scale and found that In the high degree of immersion,experiential micro lessons can have a positive effect on the learning effect.Questionnaires and interviews with teachers on the use of micro-courses in teaching revealed that the teacher's educational philosophy determines the effectiveness of experiential micro-teaching.This study is an attempt of experiential micro-teaching in the teaching of bioinformatics in middle schools.It has explored the introduction of micro-curriculum and other new techniques to the classroom,and also provided ideas for realizing other technology in the middle school biology teaching.
