Can university teachers publish picture books and textbooks as scientific research?

Count. Very few textbooks are scientific research achievements, and most textbooks are academic achievements. Our common scientific research results are obtained through subject research or scientific research projects. The results of a project or scientific research project are mainly papers, monographs and research reports. Although teaching materials can also show scientific research results, they are not common. It can be seen that it is possible to calculate scientific research results by publishing teaching materials, but the more common scientific research results are papers, monographs and research reports.
