In a desperate attempt to improve high school classroom performances, recently,

schools have begun to move towards incorporating cooperative learning strategies into

their classrooms. Generally, cooperative learning strategies can be described as the

use of small groups to encourage learners work together and accomplish shared goals

and subsequently maximize theirs and othersí potential. In an attempt to evaluate the

effectiveness of this strategy on classroom learning, this study compares the gains in

means of scores between a group taught using cooperative learning strategies and

another group taught using non-cooperative learning strategies.

Fifty-three students taking Algebra I were given a pretest before administering

this strategy then a posttests afterwards to determine the normalized gain based on the

Hake equation. Thirty-one students participated in cooperative learning out of which

77% showed a net mean positive gain whereas, the 22 students in the non-cooperative

group had a positive gain of 54%. Comparison of these results did not indicate any

statistical significance between the two groups. However, it was observed that students

who worked in cooperative groups were more engaged, more responsible in completing

group assignments and more organized while working in their respective groups. These

results may encourage the practice of cooperative learning strategies in a high schoollevel
