  •  The key to the 'gyrating' graph (1+ / 0-)
    Recommended by:

    is to look where the function crosses 0. If it crosses at -2, then (x+2) is a factor. Then, to solve the solution, you have to make sure that everything multiplies up to -42 at x=0, which means that you needed to repeat one of the factors, (x-2) if I remember correctly.

    These were tough questions, but only insofar as they tested a deeper understanding of the math rather than just asking:

    x*3 + 6 = 9, solve for x

    •  My problem with the test is that it only rewards (0+ / 0-)

      the final result, without really rewarding understanding.

      What I mean is this:

      That "gyrating" function question is worth 1 point. Either you get ALL of the terms, and get the point, or you get nothing if you miss anything.

      What I would do is double or even triple the point value of each question, and allow students to EXPLAIN their work for partial credit (somewhere between 1/3 and 2/3).
