Why not?  A WebQuest is a perfectly good way to learn something new and different.  The fact that a different approach is used might help you learn something that seem difficult when presented in a different fashion.

Of course you can!  However there many different types of materials that can be understood by reading printed material.  There is fiction, non-fiction, prose, poetry, plays and technical stuff.  Each different type of material may be best understood by a different reading technique.  This technique was developed to maximize the understanding of the type of materials commonly found in mathematics and scientific textbooks.

It is very simple -- there are only a certain number of hours in the school day and the poor English teacher does not have enough time to teach a student how to understand a mathematics or scientific textbook.  Yes, we DO assume that the English teacher does understand how to read such a textbook.  Besides, as a resident of the Commonwealth of Virginia what a student learns is very much influenced by the types of things that will be evaluated on Standards Of Learning (SOL) examinations.  Even though a high school student would usually take four years of math and four years of science classes, there is no SOL requirement in English that a student has to have the skills to be able to read and understand a math/science textbook.

If you pay attention and strive to succeed at the conclusion of this WebQuest you will read a section in your previously incomprehensible math or science textbook and actually understand most of the subject matter.  You will be able to astound your classmates and your teacher with truly intelligent questions about what somebody thinks you should be learning.  More importantly, when you do happen across something that is not really clear from your textbook, your will be able to listen in the classroom to see if your teacher happens to address the subject.  If not, you will be able to ask for specific help from your teacher.  Asking good questions about something not clearly addressed in either the textbook or during class lectures is an excellent method to impress your teacher, who sooner or later will be making decisions about the grade that you deserve.
