From: E A H To: Teacher2Teacher Public Discussion Date: 2006101117:49:42 Subject: Re: Re: Re: Re: : Purpose of studying algebra It seems to me that Mathematics, including, but not limited to Algebra is a form of communication. I think many people would be surprised to hear a student ask why do we need to read and write? The answer would be obvious, it allows us to communicate over space and time with one another. We don't justify the ability to read and write by listing all the things we can do with reading and writing. If I were an Algebra teacher, and I needed to tell a child why they will need to know this, I would make sure that understoodnd that this is a form of communication. Once they accepted that notion, I would say that "It my hope as someone who cares about you, that you would not choose to be ignorant of a form of communication simply because you do not have an immediate need for it. If you would, I urge you to seriously re-think that choice. If you have done all you wish in life at 13 or 14 years old you should probably not bother, otherwise please don't limit your choices beause you were too lazy or too scared to try something." As far as why to learn a specific topic, such as Why do I need to know how to graph a line? It would seem to me to be analagous to finding fault with knowing a certain vocabulary word. When will I need to use the word vicious, or bedraggled? I suppose you could make a case for why we don't need to know most idividual words or phrases, we could probably get by with a very small core of words. Increasing our vocabulary, increases our potential level of communicating, whether we choose to take advantage of it is up to us. I would then show them a situation which required Algebra to communicate an idea, perhaps one slightly too difficult for them to solve.
