Cases Study Of Physical Experiment Of Digital Sensor In Middle School

Physics is an experimental discipline,and the physical experiment is a practical course that sets up the training of students’ innovative ability and the training of scientific experiment method.The new curriculum standard calls for the strengthening of information technology education,and one of the best practices combined with physical experiments is the application of digital sensors.However,in traditional physics experiments,most of the exploratory experiments do not have an intuitive quantitative presentation,which limits students’ learning.Sensor physics experiments are very important in teaching and how to effectively use the sensor to carry out physical exploration experiments to make up for the drawbacks of traditional experiments is a new research topic.This paper makes a study on the design of physics experiment of digital sensor in middle school by means of literature analysis,questionnaire survey and case analysis.First of all,the paper investigates the research status of sensor physics experiment at home and abroad,which include defines the related concepts,discusses the theoretical basis of this thesis,the interpretation of the new physical standards,perception of sensor physics experiment requirements.A questionnaire on the status quo of teachers and students on the physical experiment of digital sensor was compiled.The investigation and statistical analysis of some physics teachers,the students of Ningxia University affiliated middle school and the physics normal students in Ningxia University were done.Followed by combing the middle school physics experiment,three teaching cases of sensor physics experiment were determined,such as Micro-current sensor experiment,Light intensity sensor experiment and Temperature sensor experiment.The factors influencing the physical experiment of the sensor were discussed,and the basic flow chart of the case design of the sensor physics experiment was developed.Finally,based on the previous research,the experimental instructions for the above three teaching cases were compiled.And the corresponding teaching design was written and got some useful conclusions.It is hoped that the first-line middle school teachers will strengthen the research of sensor experiment in physics experiment teaching and expect the research work of this thesis will provide the first-line physics teachers with reference function in the sensor physics experiment method and strategy teaching.
