A multifunctional teaching writing board and teaching system

Abstract

The invention discloses a multifunctional teaching writing board, which comprises a camera, two rotating lighting boards, a first connecting shaft, a writing board, a side frame, a lower frame, an upper frame, a second connecting shaft, and a base , integrated control terminal and receiving terminal. The invention also discloses a teaching system, which includes a multifunctional teaching writing board, a host PC, a projector and a projection screen. The multi-functional teaching writing board and teaching system play an important role in assisting the teaching of electronic technology, such as in experimental demonstration, training guidance, teacher's lesson preparation and evaluation, students' training works or various homework display and other teaching links. In-depth application helps to improve the quality of teaching and the level of teaching and research.

Description

technical field [0001] The invention relates to the technical field of multimedia assisted teaching, in particular to a multifunctional teaching writing board and a teaching system. Background technique [0002] In the teaching of experimental courses, teachers often need to provide various practical training and operation guidance, such as experimental demonstration of circuits, display of electronic components and circuit boards, demonstration of circuit experimental phenomena, operation demonstration of electronic measuring instruments and tools, and guidance on circuit production , Circuit failure analysis and so on. Teachers' on-site demonstration guidance is the key to students' understanding and understanding of electronic circuits, and the successful completion of related experiments or practical training, which has a direct impact on students' mastery of various operating skills. [0003] In the past, when teachers gave teaching demonstrations to students, they usu...

Problems solved by technology

[0003] In the past, when teachers gave teaching demonstrations to students, they usually presented the experimental phenomena or operation process directly to the students. Since the electronic components, circuits and instrument panels are small, the visibility of this intuitive demonstration method is poor. The purpose of allowing all students to participate in the observation cannot be achieved. Even the students sitting in the front row may not be able to see clearly. Sometimes the students have to go to the front of the podium to watch the demonstration in batches, which not only wastes a lot of time, but also affects the demonstration teaching. Effect

Some students can’t or don’t want to do it in the practical training because they can’t see the teacher’s operation demonstration clearly, and lose interest in the practical training operation. This kind of problem exists in the teaching of many experimental courses
