Potential

There are a number of ways evaulating a textbook could be helpful in the classroom.  First, we want to use sources in the classroom that match up to the grade level.  Using techniques such as syllable counting could show whether or not the students' reading level matches up with the text would be beneficial.  Second, we have to make sure the content is grade-level appropriate.  For mathematics, it is a bit harder to evaluate objectively, and might require a "pick-and-choose" method anyway.  Finally, text evaulation reveals to the teacher what content should be taught in the classroom.  If the teacher does not understand aspects or the language used in the book, it is better to skip the text.
