| In the background of the new curriculum reform,"students as the centered and teachers as the leader" is advocated.In order to change the phenomenon of neglecting student’s subjectivity and practical ability in teaching,practical teaching has gradually come to the podium.The role-playing method is just one of many practical teaching methods,focusing on the cultivation of student’s subjectivity and creativity and allowing students to learn in a relaxed and free classroom atmosphere,so as to achieve true learning and application.Taking the Biology teachers and senior one students of Shenzhen Buji Senior Middle School as the research and experimental objects and the "Genetics and Evolution"of the PEP compulsory two as the practical textbook,This practical research on role-playing methods in high school biology teaching is Carried out.Firstly,through the questionnaire survey and interview,we deeply learn the application status of role-playing method in the experimental school,and put forward the existing problems and analysis their cause.Then,we sort out the implementation steps of the role-playing method and select the teaching content which is suitable for the role-playing method in the textbook,and we design the teaching case of role-playing method on this basis,Finally,we apply the teaching case to practice,and use the biological learning interest scale,classroom participation observation scale and biological test questions as evaluation tools to evaluate the effect of the role-playing method in teaching.The experimental results are as follows:the first,after the experiment,we collect the data of the biological learning interest scale of the experimental and control students,and acquire their t-test result that P=0.019<0.05,which indicate that compared with the control class,the biological learning interest of experimental class students has been significantly improved;the second,in the observation of the classroom,we found that in the experimental class most students who actively participate in the inquiry activities are able to discuss with the teachers and classmates around the inquiry problems and clearly explain their ideas;the third,after the experiment,we collect the Biological academic record of the experimental class and the control class,and acquire their average score are 49.22 and 43.70 separately,and their t-test result that P=0.031<0.05,which indicates that compared with the control class,the Biological academic record of experimental class’s has been significantly improved.Therefore,it is concluded that the use of role-playing in high school biology classrooms,first of all,helps to increase students’ interest in biology.In a relaxed and free classroom atmosphere,students show a strong desire for learning and can learn independently.Secondly,it helps to increase students’ classroom participation.Students can participate in all aspects of inquiry activities,including acting,observing,questioning,discussing,etc.Finally,it can promote students’understanding and internalization of knowledge.In the process of exploring the mysteries of biology,students constantly build and improve their own knowledge system in combination with practical experience,and truly realize the internalization of knowledge.In addition,in practical research,it was found that the role-playing method will have the problems of limited number of participants and easy occurrence of unexpected situations.In summary,role-playing is an effective way of biology teaching in high school. |
