Case Study 9.1: Improving Teaching
------------------------------------------------------------------
Variables:

     ID           Student identifier
     SEX          Gender of Student
     CLASS        Class:  1,2,3 (see Design notes below)

     P1, P2, P3   Prestest score (out of 100) for UNIT = 1,2,3
     F1, F2, F3   Posttest score (out of 100) for UNIT = 1,2,3
     S1, S2, S3   Attitude score  (out of 60) for UNIT = 1,2,3
     H1, H2, H3   Higher learning test score for UNIT = 1,2,3

                    (1,2,3 = partially correct, 4 = correct)


     T,K,A,V      Learning Style Preference:
                    T = Tactile,  K = Kinesthetic
                    A = Auditory, V = Visual
                    (60+ ==> student has strong preference for
                             that learning style)
------------------------------------------------------------------
Design:

    3 science units (UNIT = 1,2,3) were taught to each class.
    For each UNIT, one class (C = Control) was taught using
    traditional methods; the other two classes incorporated
    learning style preference activities (E = Experiment).
    The Control group assignments for each UNIT were:

    UNIT = 1 : C = CLASS 3
    UNIT = 2 : C = CLASS 1
    UNIT = 3 : C = CLASS 2
