To test the hypotheses on the effectiveness of mastery learning method on students' attitude and performance, as well as their motivation, a randomly selected sample of female high school students was divided into two groups. One group used the mastery learning method, while the other utilized the ordinary method of learning in a chemistry course. Both attitude towards chemistry, levels of motivation, and knowledge in chemistry were measured before and after the treatment. Comparison of the pre- and post-test data revealed a positive change in students' attitude toward Chemistry and improvement in both motivation and achievement for the mastery learning group.
