Research On Application Of Middle School Chemistry Experiment Teaching Assisted With Virtual Simulation Technology

As an important part of chemistry,chemical experiments can greatly help stimulate students' interest in learning and improve their scientific literacy.In the general trend of promoting the deep integration of information technology and experimental teaching in higher education,virtual simulation technology in modern information technology stands out.With the continuous downward extension of technology development,it affects the teaching activities of basic education.The general senior high school chemistry curriculum standard(2017 edition)also advocates that teachers should pay attention to the development of modern information technology and actively explore the deep integration of modern information technology and chemical experiments.Applying virtual simulation technology and inherent advantages to experimental teaching can make up for the limitations of chemical experiment teaching in middle schools to a certain extent.This hesis mainly summarizes and discusses the status quo of the virtual simulation technology in the middle school chemistry experiment teaching at home and abroad,the advantages and disadvantages of its supplementary role in experiment teaching,and the theoretical basis of learning.The experimental contents of compulsory high school chemistrymodule are divided into three categories: virtual penetration,virtual integration,virtual expansion.We can combine with the auxiliary experiment teaching strategy,innovate the content about evaluating experiment teaching,design the principle about designing experiment teaching,and build the "three three three three" virtual simulation technology platform to assist the pattern experimental teaching mode.Then,using the teaching mode to design three typical case contents of virtual simulation experiment teaching,and select some students as the research object to further investigate the effect of experiment teaching mode.The practice effect of experiment teaching assisted with virtual simulation technology was comprehensively investigated by means of self-assessment form of experiment records,questionnaire survey and interview.Finally,it comes to the conclusion that middle school chemistry experiment teaching assisted with virtual simulation technology can construct a good teaching environment and effectively strengthen the effect of experiment teaching.It has a significant impact on students' learning attitudes and habits.Through the research on this subject,the author believes that improving students' core literacy of chemistry discipline can't be achieved overnight.It needs scientific teaching ideas and learning methods,properly introducing the frontier technology of scientificresearch,actively exploring the integration of virtual simulation technology and chemical experiment,in order to achieve the best auxiliary effect.
