How taxonomies help teachers??

Using taxonomies help teachers mainly in two things planing and assessing. I f the teacher is using the taxonomies to plan on different levels of thinking, she will make sure that her students are practicing all these levels, from knowledge to creation according to Anderson. Most of the teachers are forgetting about these levels, and they build their work only on low levels, but this shouldn't be the case. Then, a teacher should build her assessment tools on different levels, and  she should make sure that she worked before on those levels in class, since she can't stay asking knowledge questions in class, and to ask creation ones in the exam.
As a sum, a teacher should vary her activities, assessment tools, and questions according to the different levels of thinking.
