From: Jim Wysocki To: Teacher2Teacher Public Discussion Date: 2000020101:17:12 Subject: Re: Purpose of studying algebra Hear me out. I find it interesting that we need to provide justification to the students about why a particular subject is valuable. Apparently the idea that we study different subjects 1) for the sake of knowledge and 2) for the mental discipline we gain are two justifications that nobody accepts, thus we need to come up with artificial applications and "realworld" connections about where we use math. Realistically, if you are in an innercity school there is no justification for studying it that you can give students because they see to many examples around them that prove you can survive in this world without knowing the solution to "If x squared minus three times x minus four equals zero, what is x?" At the same time, in a welltodo neighborhood, any "realworld" application will be shallow at best as these students will see algebra as their stepping stone to college... and that is all they need to know about it. Be honest with your students. Why do we study algebra? Because it is a foundational subject in mathematics that trains you to think and reason in a logical and orderly manner. Will we be able to use this stuff later? Sure, but that is not really the point here.
