But textbooks are relied upon quite heavily by less-experienced and less-knowledgeable lecturers. More typically, analysis performed as a part of the Third International Mathematics and Science Study indicates that textbooks have a significant influence on teachers’ choices about tips on how to present their subject material.

Most of the responses could be grouped into a quantity of classes, which are presented and mentioned …
