Discussion On The Integration And Optimization Of High School Biological Demonstration Experiment Under The New Curriculum Standard

Since the new curriculum reform,experimental teaching has been a high school biology teaching practice in the process of key issues and difficult problems.High school biology course as a science course,the effective implementation of its teaching is inseparable from the experimental teaching.However,due to the pressure of college entrance examination,hours of schedule,poor experimental basic conditions and the popularity of multimedia technology applications,high school biology teaching teaching situation is not optimistic.As an important part of experimental teaching,compared with the experiment of laboratory students,the demonstration experiment has the characteristics of simple experimental conditions,easy operation and easy implementation,and can be used as an important teaching method to optimize the teaching system of biological experiment in high school and carry out the new curriculum idea.How to rationally allocate students 'experiment and teacher demonstration experiment,to demonstrate the experiment and the combination of student experiment,improve the problems of experimental teaching,implement the new curriculum concept,improve students' biological science literacy become an urgent problem to be solved.In this study,the high school biology "molecules and cells" as an example,the method of literature analysis,questionnaire survey,interview and so on is used to optimize the demonstration experiment of how to choose high school biological demonstration experiment.On the basis of analyzing the background and significance of the research,the author understands the relevant knowledge of the demonstration experiment and combs the theoretical basis of the research,and then carries on the investigation and research,including the investigation and analysis of the present situation of the high school biological experiment teaching,the high school biological demonstration experiment Application of the feasibility analysis,high school bio-demonstration experiment integration optimization.This paper explores the teaching status of high school biology experiment and the attitude of high school students to biological experiment in this paper,which is a high school biology teacher in Kaifeng city of Anhui province and Zongyang county of Anhui province and students who have practiced high school high school year To demonstrate the necessity of experimenting and optimizing the teaching systemof high school biological experiment.According to the specific content standard in the new curriculum standard,combining with the nature of the high school biology course and the psychological characteristics of the high school student,the feasibility of optimizing the experimental teaching system of high school biology experiment is discussed with the demonstration experiment.Then,according to the data of the questionnaire survey and the specific requirements of the new curriculum standards,combined with the characteristics of the demonstration experiment,the biological experiment is divided into microscope observation experiment,verification experiment,exploratory experiment,simulation Experiments,and then from the various types of experiments selected a relatively appropriate biological demonstration experiments,and high school biology demonstration experiment design principles,demonstration of experimental material selection,demonstration of experimental demonstration method selection,demonstration of teaching strategies and other aspects of the proposed Some suggestions.
