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
