The Research On Website For Comparison Of The Effectiveness Of Learning Resources On High School Biology Based On AB Testing

Education and scientific research are the foundation of education development.Biology teachers in senior high school are the direct participants of education work and the direct beneficiaries of educational research achievements.At present,most of the education and scientific research work of high school biology teachers adopts methods and methods such as experience summary,case analysis and questionnaire survey,which are highly subjective.Although part of teachers can design rigorous scientific control experiment,due to the complex process,design experiments,conducting experiment,statistic results more trouble,but high school biology teachers often lack the necessary experimental conditions and bear the heavy teaching task,in fact high school biology teachers rarely have the opportunity to rigorous scientific experiments,Even if we can read other people’s teaching research results from periodicals,the actual promotion and application of existing results often fail to reach the expected goal due to the great difference between the background and object of these results and the real teaching environment.AB test is a mature mode of online control experiment,which has the advantages of simple operation and reliable results.With the popularization of Internet information technology,middle school teachers have the conditions to use information technology to carry out teaching and scientific research,so can high school biology teachers use AB test to carry out scientific research and teaching of high school biology? In order to explore this problem,this paper designs and develops an AB test website from the scientific research teaching needs of high school biology teachers,and discusses this problem based on it.The specific methods are as follows:Methods:(1)Through literature search,it summarizes the research situation and evolution of home and abroad,analyzes the connotation and extension of teaching effectiveness;on the other hand,it summarizes the use technology,application scenarios and operation specifications of AB test at home and abroad.A research framework and experimental ideas for using the AB test to learn resource effectiveness are developed.(2)Learned about the teacher’s knowledge and possible acceptance of AB tests through questionnaires,and investigated the common methods and ideal methods of high school biology teachers’ lesson preparation and teaching and research.Survey results found that high school biology teachers almost do not understand the AB test,but understand and deeply agree with control experiment,at the same time the teacher in the teaching and lesson preparation choose material,mainly based on objective standards,and reference to colleagues,students,teaching provided the relevant information,in the face of complex lesson preparation task will play their subjective views.(3)Based on the results of the above literature study and questionnaire survey,designed and produced a website based on the AB test for study resource effectiveness comparison,and designed two sections of study resource samples and test samples added to the content of the site.Select six shifts at the same level in the same grade,and test on the website twice before and after.The test students are automatically randomly divided into two groups by the website.Each group will learn different learning resources,and then test the knowledge points with the same test questions.Comparison of whether the test results reflect the quality differences of the designed learning resource sample.Results:(1)Through the questionnaire survey,it was found that what the teachers most hope is that the lesson preparation and teaching and research results can be well recorded for subsequent use and modification,so as to achieve superimposed progress.At the same time,the teachers also hope that the teaching and research can be refined to smaller knowledge points.It can be considered that well-documented and detailed research knowledge points are the real needs of teachers.(2)The first experiment was carried out in two classes,on two knowledge points with little difficulty and small difference in learning data quality,the two groups scored 70% and 67%,respectively,and c 2=0.16 <3.84.In the knowledge points,the two teaching samples differ significantly,the two groups scored 86% and 65%,c 2=5.98> 3.84.In terms of the knowledge points where the teaching concepts of the two teaching resources were difficult for subjective judgment,the score rate of students in the two groups was 72%and 54%,and x~2=3.27 <3.84.(3)The second experiment increased the number of test questions and the number of students,and the experimental results were overall the same as expected.That is,when the quality of the two teaching materials is close to the test questions,there was no significant difference in the student score rate in the two groups.In the two test questions with large differences in the quality of teaching materials,the overall scores rate of the two groups varied greatly and significantly.In the second experiment,the author gained both the number of tests and students,the results are overall the same as we expect.The scoring percentage are almost the same between two groups when the quality of teaching resources is close to each other.When the quality of teaching resources is quite different,there is significant difference between scoring percentages of the two groups.These results show that the use of the teaching website can distinguish the advantages and disadvantages of the quality of learning resources and avoid false positives to a certain extent when the teaching quality difference is not small.At the same time,for the teaching resources that are difficult to judge from the teaching experience,the results of the website can provide a reference basis based on the teaching experience.In short,the use of AB test and Internet technology can provide convenient and effective assistance for high school biology teachers in teaching and research and lesson preparation and provide more scientific solutions for teaching and research.This paper will provide new ideas and reference for high school biology teachers and Internet practitioners to improve the quality of teaching and research and promote the teaching development.
