Explore Physics Experiment In Junior Middle School Using Mobile Intelligent Devices

This thesis is based on mobile intelligent equipment to explore physics experiment in junior middle school,mobile intelligence devices refer to mobile phone,tablet PC,and small-scale integrated sensor Pocketlab.Physical experimental cases using mobile intelligence equipments are studied for example:explore the principle of the reflector plate;explore the transmittance of different colors of water to light;explore the endothermic ability to different color objects;explore temperature changes in water and sand;explore the changes in atmospheric pressure;explore the relationship between pressure and temperature;explore the voice features based on smart phone.Then part of the above-mentioned exploration experiments are used in the specific teaching design.By using mobile intelligence’s digital experiments and creating a living physical context,breaking through the teaching priorities,and providing a new teaching strategy for physics experiment teaching in middle school.Compare physical experiment based on mobile intelligent equipment with traditional physics experiment and DIS experiment,the obvious advantages is that it is easy to explore the physical problems in real life situation,the presentation of knowledge is more intuitive,and learning knowledge is more efficient.Of course in the teaching practice also can not blindly use the mobile intelligent equipment completely,we need to combine the characteristics of the teaching content,the advantages of mobile intelligent equipment should be fully utilized,to explore the physics of life,to promote the development of scientific literacy among students.
