Research On Application Of Virtual Teaching Resources In Biology Experiment Teaching In Junior Middle School

Biology is a subject based on experiment,through which students can be trained to observe,practice,analyze and solve problems.However,in junior high school biology experimental teaching,there are some problems,such as some experimental materials are not easy to obtain,some experimental phenomena are not easy to observe,resulting in the experimental effect is not rational,and the learning effect is not satisfactory.The virtual experiment based on software provides a new way to solve this problem.In view of this,this paper carried out the research on the application method of virtual experiment in junior high school biology experiment teaching.On the basis of summarizing the related research status at home and abroad,this study,guided by constructivism learning theory,behaviorism learning theory and Humanism learning theory,combined with the characteristics of junior high school biological experiment,puts forward the application method of virtual experiment in junior high school biological experiment teaching.In the teaching preparation stage.Before class,the teacher analyzes the teaching content,students’ characteristics and teaching objectives,judges whether the experiment is suitable for the use of virtual experiment and how to carry out virtual experiment,and the students do a good job of preview before class according to teacher’s guidance and teaching materials.In the stage of creating situation.After teachers create a certain situation to stimulate students’ interest in learning,they introduce experimental subjects and propose specific tasks of this section of the experiment.In the virtual experiment stage.When students are doing virtual experiments,teachers should guide them around and answer the questions they encounter in the virtual experiments at any time.Students carefully observe and record the experimental phenomena during the virtual experiment.In the sharing and communication stage.After students sort out and summarize their observation phenomena and results,they will display them through the teacher’s organization.Teachers need to give evaluation,and at the same time,they will answer the questions raised by students.At the stage of summary and consolidation.After class,teachers need to reflect on this experimental lesson,and students need to consolidate their own weak points through classroom learning.In order to verify the effectiveness of virtual experiment in junior high school biology experimentteaching,this study analyzes the effect through the form of learning achievement and questionnaire.The results show that: students use virtual experiments to carry out experiments,the results are effectively improved,and students’ satisfaction with virtual experiments is high,which can effectively improve students’ observation ability,practical ability and other comprehensive abilities.Therefore,the virtual experiment proposed in this study has a certain value in the application of biological experiment teaching in junior high school.
