Investigation On Application Of Digital Sensing Technology In Chemistry Teaching In Junior High School

Conventional chemistry experiments are subject to numerous restrictions in middle school teaching.Digital sensing technology can cover the shortage of conventional experiments.Considering making the most of the advantages of digital sensing technology and promote chemistry teaching.Understanding the status quo of the application of digital sensing experiments in chemistry teaching is the basis and prerequisite for improving the effectiveness of digital sensing experiments.Based on domestic and foreign related research,this article first takes a junior high school chemistry teacher in Suzhou as the research object.And issues a self-edited questionnaire survey on chemistry digital experiment teaching.In order to understand the current status of digital sensing experiments in junior high school.And explore the cognition,mastery,and application of digital sensor experiments by different types of teachers.After analyzing the survery results,two teaching cases of digital sensory technology are selected for analysis and research.This is for the sake of providing a reference for teachers' digital sensory experiment teaching.Finally,the conclusions are as follows:(1)The level of digital sensing experiment equipment in Su Zhou is good,but the distribution is uneven.(2)The application of sensors in junior high school is narrow,and it is more limited to public class display and teaching competition.(3)On the cognition of digital experiments,Teachers from schools in zones of different exist significant discrepancies.Teachers in metropolitan areas have a higher awareness than teachers in county(district)urban and township schools.(4)Most teachers recognize digital sensing experiments,but the older the teacher,the less willing and confident they are to learn digital sensing technology.(5)There is a contradiction between teachers' understanding and behavior of digital sensing experiment teaching.Three suggestions are raised in this paper:(1)All departments play a synergistic role and make a suitable distribution of material resources;(2)Implement layered training and establish a multi-level communication platform;(3)Stimulate digital experiment renovation and actively carry out extracurricular teaching activities.
