Problems solved by technology

However, because the wooden desktop is relatively easy to damage, the teacher needs to take the students to a special chemistry or physics experiment table for experiments, and the special chemistry or physics experiment table is generally placed in the laboratory, so the teacher needs to bring the students to the Returning to the classroom to teach after finishing the experiment in the laboratory not only wastes the class time but also affects the teaching effect

Description

technical field [0001] The invention belongs to the field of teaching materials, and in particular relates to a ceramic board for the table top of a teaching platform. Background technique [0002] Existing dais is generally used for teachers to use when giving lectures in the classroom, and its desktop is generally a wooden desktop for teachers to place teaching aids. At present, in order to make the lecture content more vivid and easy for students to understand and absorb, many physics teachers and chemistry teachers usually combine physics experiments and chemical experiments to explain the lecture content in the classroom. However, because the wooden desktop is relatively easy to damage, the teacher needs to take the students to a special chemistry or physics experiment table for experiments, and the special chemistry or physics experiment table is usually placed in the laboratory, so the teacher needs to bring the students to the Returning to the classroom to teach aft...
