Physicochemical experiment lesson preparation system applied to online classroom

Abstract

The physical and chemical experiment lesson preparation system applied to the online class. The system comprises a lesson preparation platform and a processor, wherein the lesson preparation platformcomprises a recording unit and a table body, the recording unit comprises a positioning audio-video acquisition module and a dynamic audio-video acquisition module, the audio-video information acquired by the recording unit is transmitted to the processor to be sorted and stored, the table top of the table body is rectangular, sliding rails are arranged on the short edges of the table top, slidinggrooves are formed in the long edges of the table top, the two positioning audio and video obtaining modules are arranged on the sliding rails on the two short edges of the table top respectively, and the two dynamic audio and video obtaining modules are arranged in the sliding grooves in the two long edges of the table top respectively. The system is advantaged in that a movable exhibition standis arranged in the middle of the table top and used for assisting an experiment, a professional lesson preparation platform is provided for a teacher to do the experiment, omnibearing video and audioacquisition is conducted through the recording unit, students can know the experiment process more clearly and visually, and the students can understand teaching content easily.

Description

technical field [0001] The invention relates to the field of modern teaching technology based on information technology, in particular to a physical and chemical experiment lesson preparation system applied to network classrooms. Background technique [0002] Network teaching is widely used. Teachers conduct cross-regional teaching to students through network classrooms. Physical and chemical experiments, as an important part of teaching, also need to adapt to network teaching. The existing physical and chemical experiment network courses are only recorded through simple experimental processes. Teachers It is not enough to explain the experimental process to the students. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes a physical and chemical experiment lesson preparation system applied to network classrooms, including a lesson preparation platform and a processor, the lesson preparation platform includes a rec...
