"Would a real person need to solve this problem?...the solution realistic?...using a system of 2 equations?...in what ways does this problem help our students become better problem solvers?"...problem you will only find in a textbook...bizarre...how many different ways just 50 words can fail to square with reality. Why does each chaperone have to drive? Why can't we take 5 vans? Why do our vehicles have to seat the exact number of people in our group & no more?...Algebra teachers sell students a cheap distortion of the real world while insisting at the same time that it really is the real world. The cognitive dissonance is obvious & terrible. Students know the difference. It cheapens my relationship to them & their relationship to mathematics when you ask me to lie to them...Not only are the short-term consequences devastating but it makes that person distrustful or wary of the real thing. Make no mistake. We are making an alien of algebra. We are doing real damage here."
