(i) pre-test of
students’ mathematics achievement and attitudes towards mathematics was given to both experimental and control
groups, (ii) control and experimental groups were guided by the two teachers (one from each school) who had more
than twelve years of teaching experience in mathematics. Each teacher taught two classes in each school in one
academic session for the duration of 15 -weeks, (iii) post-test of students’ mathematics achievement and attitudes
towards mathematics was given to both experimental and control groups. Table 1 shows a graphic form of quasiexperimental
design of this study. A represents the experimental group while B represents the control group. O1
represents the pre-test while the post-test is represented as O2 for the experimental and control groups respectively.
The cooperative learning treatment is represented as X.
