Abstract This study was designed to compare the effects of Team Assisted Individualization
(TAI) and Student Teams-Achievement Divisions (STAD) on fourth grade students’
academic achievement in and attitudes towards mathematics.
Seven classes of a school
were randomly selected for this experimental study.
Two of these were given instruction
through TAI; two through STAD, and the remaining three were treated as a control group.
For the purpose of the data analysis regarding academic achievement, the 3X1 covariance
analysis was used to compare the groups.
As a result of this comparison, both the TAI and
STAD methods were found to have positive effects (d=1.003 for TAI and d=0.40 for
STAD) on students’ academic achievement in mathematics.
The pairwise comparisons
showed that the TAI method had a more significant effect than the STAD method. The
scores for the attitude towards mathematics were analyzed by using non-parametric
statistics. As a result of this analysis, no significant difference was observed regarding
students’ attitudes towards mathematics.
