Problems solved by technology

[0002] At present, due to the demand for high-quality talents and the improvement of the quality of the people, the expansion of enrollment and overcrowding in various colleges and universities has become a problem faced by every college. With the increase in the number of colleges and universities, the problem of insufficient teaching space has become more and more serious. , but with the diversification and diversification of teaching, ordinary classrooms can no longer meet all teaching requirements. Therefore, we can only add classrooms to new teaching buildings or renovate existing classrooms to change ordinary classrooms into multimedia classrooms and seminars. Classrooms, design and drawing classrooms, self-study classrooms and examination classrooms and other multi-functional classrooms, but the new teaching building will inevitably increase the school's operating costs, and the reconstruction of classrooms will virtually reduce the number of classrooms, and the utilization rate of multi-functional classrooms It is not high, which will cause a great waste of classroom resources and make the problem of insufficient teaching space worse
