Practical Research On PAD Teaching Mode In Biology Teaching In Senior High School ——Take The Module Of Molecules And Cells As An Example

The 2017 edition of the 2020 revision of the biology curriculum standard for senior high schools points out that the classroom teaching content should be few and precise,should conform to the cognitive development of students,and the learning process is a process in which students actively participate."PAD " is a new teaching mode.In the form of teaching organization,the classroom time is divided into two parts,half of which are taught by teachers,and the other half organize students to conduct interactive learning and discussion.The teaching of biology course integrates the characteristics of "life" and the vitality education full of "life" into all links of course teaching and teaching reform,so as to achieve the purpose of Building Morality and cultivating people and improving the core quality of biology.The teaching idea of PAD teaching mode is a new teaching idea that emphasizes student-centered,theoretical knowledge and ability training.Therefore,the split classroom teaching model meets the requirements of high school biology teaching,and has important research value in high school biology teaching practice.By consulting the literature,this study combs the research progress and relevant teaching theories of the PAD teaching mode at home and abroad.On the basis of forming PAD teaching strategies,according to the curriculum standard,learning situation and teaching progress,this study designs PAD teaching case based on Chapter 2～6 of the module of molecules and cells,a compulsory course of senior high school biology of the people’s Education Edition.In the experimental class,PAD teaching mode was used to carry out a three-month teaching practice research to explore the impact of the PAD teaching mode on biology teaching in grade one of senior high school.In the process of research,we should improve and optimize according to the teaching effect,and gradually form a more perfect teaching strategy.Taking two parallel classes in the first grade of a middle school in Hohhot as the research object,the experimental class carries out pad mode teaching and the control class carries out conventional mode teaching.In the research of teaching practice,through teacher interview,questionnaire survey and academic performance analysis,this paper studies the importance of students’ pad teaching mode and the teaching effect before and after implementation.The results are as follows:（1）Through teacher interviews,it is found that teachers generally believe that PAD teaching mode can help improve learning efficiency and stimulate students’ interest in learning,but most teachers lack understanding of pad teaching mode and use it less.（2）After carrying out the research on teaching practice and analyzing the questionnaire post-test data of the experimental class and the control class,it is found that there are statistically significant differences in the survey data results of the three dimensions of students’ classroom participation,learning attitude and learning interest（P<0.05）,indicating that the use of PAD teaching mode has significantly improved the interaction between teachers and students in the classroom,improved students’ learning attitude and stimulated students’ learning interest.（3）The students’ final examination results show that the average score of the experimental class is 78.44 points and the average score of the control class is 71.42 points.The average score of the experimental class is 7.02 points higher than the average score of the control class,and the difference of the test results is statistically significant（P<0.05）,which proves that the application of PAD teaching mode had positive significance to improving the learning efficiency.To sum up,the application of PAD teaching mode in senior high school biology teaching can effectively help students improve classroom participation and learning interest,improve learning attitude,improve students’ recognition of the new teaching mode,and improve students’ learning efficiency to a certain extent.Combined with the teaching cases implemented in the teaching process,it provides a reference for front-line teachers to carry out the high school biology split classroom teaching mode.
