Research Methodology

Design

The study adopted a pretest, post-test control group quasi experimental design using 3 x 2 factorial matrix (campbell and Stanley, 1971). The design is shown structurally as follows.

O1            X1            O2            E1
O3            X2            O4            E2
O5            X3            O6             C

Where

O1, O3 and O5 represent pretest observations.

O2, O4 and O6 represent post-test observation

X1 is experimental treatment of STAD, (with inter-team competition)

X2 experimental treatment of STAD 2 (without inter-team competition)

X3 is the conventional lecture method (control)
