Research On Online And Offline Hybrid Teaching Practice Of Biology In Senior High School

The advancement of education will promote the development of Internet technology,and the appropriate application of Internet technology in education and teaching will also promote the development of the education industry.The sudden outbreak of the epidemic in 2019 has boosted the pace of educational informatization.In response to the call of the country to suspend classes without suspending classes,online teaching methods have begun to be widely used,which has also triggered a series of reflections on online and offline teaching.Online teaching,which is not limited by time and space,gives students and teachers more choices and freedom.Face-to-face communication between teachers and students,and offline teaching,which is based on word of mouth,adds more opportunities for thinking collisions.Both online and offline teaching have their advantages,but there are also shortcomings.How to collect the great achievements of online and offline teaching,and improve their shortcomings as much as possible,in order to achieve further development of education and teaching,is an urgent issue to be solved in current secondary school education.At this point,the online and offline mixed teaching mode emerged as the times require.Based on literature review,it can be seen that hybrid teaching has been widely studied and popularized in vocational schools and universities,and lacks practice and research in high school.Therefore,it is necessary to establish a systematic mixed teaching model based on the content of textbooks and the analysis of learning situations in high school.This article uses the methods of literature research,questionnaire survey,comparative research,and classroom observation to analyze the online and offline hybrid teaching practice of high school biology.During the research process,the author first combed the era background of education informatization and the development of online education from both domestic and foreign perspectives,and analyzed the current research situation using relevant data queried by Cnki,leading to the purpose and significance of this study.The ultimate goal of teaching is for students to achieve significant development,which serves as the starting point to determine the theoretical basis of this article.Through a questionnaire survey,we learned about the current teaching situation of high school biology classrooms under different teaching modes from the perspectives of self-learning ability,classroom participation,and teaching effectiveness.We also analyzed the feasibility of blended online and offline teaching.On this basis,in line with the concept of mutual learning between teachers and students and the development of ability,a set of general processes of online and offline mixed teaching mode has been constructed.The theory needs to be tested in practice.The author uses a practical teaching section titled "The Role of Isolation in Species Formation" and One round of review course "Structure and Function of Cell Membranes" to elaborate on early analysis,pre class preparation,classroom deployment,and post class assessment.The author summarizes the effectiveness of teaching and reflects on the shortcomings of teaching.Based on the research on the current situation of hybrid teaching and combined with the author’s practical situation,this article proposes corresponding issues and countermeasures on the utilization of the new model by teachers,their own Internet technology level,and the promotion conditions of hybrid teaching mode in senior high school biology classrooms.Research findings:(1)At the level of teaching mode: Different teaching mode samples show significant differences in students’ autonomous learning ability,classroom participation,and teaching effectiveness.Among different teaching modes,blended teaching mode can enhance students’ willingness and ability to learn independently,enhance their classroom participation,and ultimately achieve maximum teaching effectiveness.The blended teaching mode multidimensional the teaching process,more in line with the needs of student groups,and achieves personalized teaching.(2)Teaching evaluation level: Teaching evaluation has a profound impact on teaching effectiveness.While reforming teaching models,it is also necessary to make changes to teaching evaluation.Enriched and diversified teaching evaluations are conducive to forming a virtuous circle of teaching processes and promoting meaningful and in-depth learning among students.The research in this article reveals the feasibility of mixed teaching,enriches the existing literature research on mixed teaching models in senior high school biology classrooms,and has certain theoretical and practical significance.
