Construction And Practice Of Hybrid-flipped Classroom Experimental Model In Biolog

The 21 st century is an era of information.Educational information requires diversified teaching methods and modern teaching methods.At present,there are still various deficiencies in biology experiment teaching in senior high school,and students’ experimental development potential is greatly limited.Flipped classroom teaching can organically combine online teaching and offline learning,and hybrid teaching can comprehensively apply a variety of teaching technologies.In order to solve the existing problems of biology experiment teaching,the mixed flipped classroom experiment model is constructed by combining flipped classroom with mixed teaching,and its effectiveness is explored through teaching practice.The research adopts the methods of literature research,questionnaire survey,experiment,statistical analysis and so on.Including the following aspects: part one is the introduction,Including research background,research situation,research objective and sense,research methods and research ideas.The second part is a theoretical review.This paper introduces the concepts of flipped classroom and mixed teaching,basic steps and main links of biological experiment teaching,and expounds the theoretical basis of the research.The third part is the construction of hybrid flipped classroom experimental model and case design.Firstly,this paper expounds the existing classical flipped classroom model and points out its shortcomings,modifies the flipped classroom model in order to improve the existing problems,and combines the advantages of Hybrid Teaching and flipped classroom to construct the hybrid flipped classroom experimental model and its teaching process;The confirmatory experiment of "comparing the decomposition of hydrogen peroxide under different conditions" and the exploratory experiment of "conditions affecting enzyme activity" are selected for teaching case design.The fourth part is the research of teaching practice.To investigate the effectiveness of the constructed Mixed Flipping Classroom experimental model,196 senior one class students parallel with each other who are from Shengze senior high school in Wenshang,Jining,Shandong Province were taken as the research target;for teaching practice research.Before the teaching experiment,the pre-test questions are prepared to test the consistency of the existing knowledge base level between the experimental group and the control group,and the survey scale is used to estimate the level of students’ learning attitude at this stage.The experimental class employs the experimental teaching design of mixed shift for teaching exercises,and the control class adopts traditional experimental teaching.After practice,the post test questions and scales are used to detect,and the statistical data are sorted out.The fifth part analyzes the teaching effect.Using SPSS software to analyze the data before and after practice,the results show that the hybrid flipped classroom experimental teaching can not only improve students’ performance,but also improve students’ learning interest,autonomous learning ability,sense of cooperation,communication level between teachers and students and learning reflection.Therefore,the hybrid flipped classroom experimental teaching is indeed better than the conventional experimental teaching,It has good teaching effect.The sixth section is the conclusion and self-examination,which concludes the research conclusions of this article,illustrates the innovation of the author in constructing the experimental model and paying attention to diversified evaluation,and reflects on his own shortcomings.
