A Study On The Application Of First Learning To Guide The Problem Evaluation Model In Biology Teaching Of Senior High School

"First learning to guide the problem evaluation model" is an effective teaching mode based on problem discovery,generation and solution,problem evaluation as a means,and taskdriven as the way to solve problems.In many schools,teachers still adopt the traditional teaching model,this "knowledge transfer" teaching makes students become passive and passive,the vast majority of students think that learning biology is memory recitation,although this habitual thinking can cope with the examination,but not conducive to the long-term development of students."First learning to guide the problem evaluation model" belongs to the "knowledge construction" teaching,emphasizing that students are the main body of the classroom,paying attention to cultivating students' ability to learn independently and actively,cooperatively exploring learning,and teachers are the guides,service providers,promoters and researchers of students' learning.Combined with teaching practice,this paper discusses the background,significance,theoretical basis and domestic research status of the study of "First learning to guide the problem evaluation model" through the research methods of literature analysis,interview and questionnaire,and conducts the traditional teaching mode and the traditional teaching mode and the domestic research status through the experimental method in the middle school where the work was carried out.The comparative practice of the "First learning to guide the problem evaluation model" was designed for the content of teaching materials and the actual situation of students,and the teaching of "First learning to guide the problem evaluation model" was carried out in the experimental groups G2012 and G2013.Traditional teaching was conducted in control groups G2014 and G2015,and the teaching materials were required for the new version of general high school biology,Molecules and Cells,for a semester from September2020 to January 2021.All four classes are parallel classes,in the first monthly examination,the experimental group and the control group's results for independent sample T test,Its P-value is0.974,indicating that there was no significant difference between the experimental group and the control group,while the P-value of the mid-term test scores is 0.049(P<0.05),and the Pvalue of the third monthly test result is 0.028(P<0.05)Significant differences,the P-value of the final exam results of 0.009(P<0.01),the difference was very significant,indicating that the experimental group after a semester of the "First learning to guide the problem evaluation model" learning,students' learning methods have changed,biological results continue to improve,and the traditional teaching model of students opened the gap.The study found that "First learning to guide the problem evaluation model" is an effective teaching mode,which can help students improve their biological achievement,develop good study habits,fully cultivate their initiative and creativity,and stimulate their enthusiasm for learning.Provide reference material for front-line teachers to use this model in high school biology classes.
