smartboard 580.Feedback and evaluation are an important part of the teaching process. Timely and effective feedback is beneficial to teachers to adjust teaching strategies and improve teaching effects in the teaching process. The electronic whiteboard software system also has built-in multiple resource libraries to provide teachers and students with various types of teaching resources with a friendly and convenient interactive interface. For example, the Flipchart Repository can be further divided into a shared library and a dedicated library. Whether it is a shared library or a dedicated library, it can be divided into a page library, a file library, an image library, and a background library. At the same time, the resource library can also establish a tree-type directory structure, which is classified according to disciplines and classes, and is convenient for searching. Teachers and students can continually modify or reconstruct these resource pools according to their needs in teaching practice.
