COALITION MATH 151, FALL 1997

        Group II (S. A. Fulling, assisted by Cary Lasher)

                              Day 8.1


    1.  Finish the jigsaw.
   
        A.  Sit in old teams (with modifications to avoid 
        duplications).  Discuss 3 problems (6 minutes each).
THIS DID NOT SEEM TOTALLY SUCCESSFUL.  MANY STUDENTS WERE NOT 
FOCUSED ON THE TASK.  

        B. Identify especially troublesome problems that deserve 
        the attention of the whole class. 
ONE PROBLEM (ROPE ATTACHED TO CARTS OVER PULLEY) WAS JUSTLY 
CRITICIZED AS NOT WELL-POSED.  THE TEAM THAT REPORTED THIS ALSO 
HAD TROUBLE SETTING THE PROBLEM UP, SO I PROMISED TO PROVIDE A 
SOLUTION LATER.  INDIVIDUAL STUDENTS ASKED ABOUT A PROBLEM 
INVOLVING VEHICLES MOVING IN OPPOSITE DIRECTIONS ON PARALLEL 
TRACKS, BUT TOO LATE TO BE DISCUSSED IN PLENARY SESSION.  I ALSO 
SHOWED HOW TO DO THE CHAIN RULE PROBLEM INVOLVING FUNCTIONS 
DEFINED GRAPHICALLY BY BROKEN LINES. 

    2.  Individual RAT on summation notation.

    3.  Start the lecture on area and Riemann sums (see next 
    day).
