However, chronic diseases such as chronic pharyngitis, varicose veins and dry eye diseases are constantly eating into their health, and the teaching environment of a large number of teachers needs to be improved.
Therefore, the editor has made an inventory of several convenient and practical teaching instruments or appliances to present to the teachers who are fighting for their posts!
Water soluble chalk
Projector
Smart conference tablet
Conference Board, also known as touch all-in-one machine, is a new era technology product integrating electronic whiteboard, projector, remote conference, camera, speaker and other functions. It was originally an instrument to improve the efficiency of the conference, but in recent years it has become more and more popular in small class teaching.
If the projector can provide services for dozens of students, the conference board is often for small classes with a small number of students.
It can show the teaching content more clearly, and can write, click, zoom and other operations directly on the screen, without the need to connect and operate the computer in a wired way like a projector.
At present, some schools have begun to purchase conference boards in bulk. I believe that many teachers can use it in the future.
Interactive teaching system
The courses of science and engineering often need a lot of interactive experiments. It takes a lot of time for teachers to prepare equipment and arrange experiments, and it is difficult to see clearly when demonstrating operations. The most headache is that some experimental instruments and materials are expensive, and the quantity that schools can purchase is extremely limited, which is difficult to meet the use needs of all students. Therefore, it is necessary to think about a way to let everyone clearly see the operation process and complete the experiment independently.
Interactive teaching system is a platform that integrates video, audio and data communication. It can display the actual operation process and provide experimental functions.
Taking the interactive teaching and training system of liquid chromatography as an example, it combines the real liquid chromatograph, virtual simulation software and interactive teaching monitoring system, and shows the whole process of using liquid chromatography.
It also provides students with virtual simulation experiment to help them complete the whole process of the experiment, so that students have a deeper understanding of the principle, structure, experimental method, operation and rules of liquid chromatography.
This has achieved the goal of interactive teaching system: more intuitive, more convenient, more efficient.
Epilogue concluding remarks
Since a long time ago, there have been a number of professional manufacturers of teaching instruments in China, which have produced a large number of high-quality teaching instruments loved by teachers and students, greatly promoting the development of science education in China.
With the continuous improvement of production technology, more and more instrument manufacturers began to flow into the teaching instrument market, and launched more and more rich products.
