I couldn't agree with you more!! I guess the point that I am trying to make is: if the TI-92 can factor any quadratic polynomial almost instantaneously, do we continue to spend 1-2 weeks having our students use paper and pencil to factor.....or do we cut it to 1-2 days with the remainder spent in applying new tech to solve more sophisticated problems? Recently, the San Jose Math Leadership group spent a day using the TI-92 and someone facetiously remarked: "Now we'll be able to finish Algebra 2 in a couple of weeks". In fact, a student who was facile with this impressive new calculator could solve almost any problem in our current (but outdated Calif. text) in a matter of seconds.
