Educational equipment work refers to the work around educational equipment, which is a collection of related behaviors. So what are the contents of educational equipment work? How does educational equipment work? In the past, the work of educational equipment was often summarized in the following words: construction, management, distribution, use and maintenance. "Construction" means construction, "management" means management, "allocation" means equipment, "use" means use, and "maintenance" means maintenance. These words are easy to understand, so I won't explain them too much here At present, there are many words about the work of educational equipment: demonstration, development, production, procurement, installation, use, management, maintenance, handling fee (retirement) and so on. The meaning of the above words is also very clear, which briefly summarizes the daily work of educational equipment at all stages. But the above words or phrases all describe the transactional work of educational equipment, so what is the essence and core of educational equipment work? Is the educational equipment work just a transactional work? Educational equipment work is aimed at educational equipment, so it must involve all aspects of the whole system and life cycle of educational equipment. Educational equipment work can be described as "involving a wide range and lasting for a long time". In the face of such complicated work, where is the key to educational equipment work? What is its core? To answer these two questions clearly, we should start with what is educational equipment and its functions. "Purpose and effective composition" are two important contents of educational equipment. The purpose of educational equipment is to serve education, and the purpose of educational equipment work is to meet teaching needs and improve education level. Only when educational equipment plays a role in education can it truly reflect its significance.
