Research On Junior Biology Teaching Practice Based On Flip We Chat Micro Lesson

This study uses WeChat public account as a medium,send micro-learning videos and learning tasks to each student before the new class,teachers design classroom teaching and group collaborative learning tasks based on the diagnostic evaluation to carry out flipped classroom teaching.Mainly use the literature method,questionnaire,interview method,time-lapse shooting observation method,evaluation gauge measurement method,experimental research method to start this research.This practical study consists of four phases,the first is the preparatory stage,by consulting extensive literature,understand the current status of biology teaching in middle schools,determine research direction,select research methods,design an evaluation gauge for the flip WeChat class.The second is the early stage of practical research,determine practical teaching chapters and make corresponding micro-lecture videos,pre-class task list,write the WeChat public account,two experimental classes and two control classes were identified through a pre-test questionnaire.The third is the practical research phase,divided into two periods,the teaching of four sections was carried out in the early stage of practice.Four classes were then tested,and conduct teaching reflection;in the later stage of practice,the entire chapter and four sections are taught on the basis of reflection.Tests and post-test questionnaires are issued.The fourth is the thesis writing stage,statistical data,analysis and conclusions are as follows.From the perspective of teachers,the development of flip WeChat classes has higher requirements for teachers' skills and qualities;from the perspective of students,flipping WeChat classes can indeed enhance students' interest in biology.Develop students' habit of autonomous learning,in the process of group inquiry,students can be continuously trained to discover problems,ability to solve problems;from the parent's perspective,parents express their support and understanding of the work of the teacher or school.Able to actively cooperate with teachers to supervise the student preparation and the use of mobile phones by students;from the perspective of teaching effect,the flip-type WeChat teaching mode has certain teaching effects.There was a significant difference between the experimental class and the control class;from the perspective of the long-term development of the biology department,the 5G era has arrived.Educational technology is constantly innovating,if we can take the essence and remove the dross according to the actual situation,we can continue to promote the innovative development of the biology department.
