Teachers should be familiar with the switch of air conditioner, hold the controller and adjust the temperature and air volume. If you see a student holding his arm to make it cold, or fan a book to make it hot, you should adjust the classroom temperature in time. Generally speaking, before the course begins, the temperature in the classroom should be consciously lowered to freeze the students' spirit.
Teaching assistants should also be familiar with audio equipment and use a mixer. Skillfully use chest Mike and hand-held Mike, keep two 9-volt batteries at hand at any time, and be ready to replace the batteries of Mike at any time. At the beginning of the course, the teaching assistant should stand next to the audio equipment and adjust the volume to an appropriate level according to the on-site situation.
Basic meaning:
A teaching assistant refers to a position that assists teachers in teaching in colleges and universities, primary and secondary schools. Usually, teaching assistants come from graduates in the same field (not necessarily from the same school), while some are part-time graduate students in master's or doctoral programs, and some are also employed. In some schools, you must have worked as a teaching assistant before you can be promoted to lecturer, professor and associate professor.
