Abstract:

In this study, we investigated the effect of classical and experimental teaching methods on successful learning of acid-base concept in chemistry. Two (grade 10) classes from a high school were selected. Students in one class were instructed by classical method and their success in learning was compared with that of the other class in which experimental method was applied. During the course of the study, part of instruction was made in the laboratory to enable the students to perform experiments within a group. In addition, Chemistry Attitute Test were applied to the students to evaluate if the experimental method had influenced their attitudes towards chemistry. Logical Thinking Ability Test, Scientific Achievement Test were applied to collect the data. It was found that the instruction by the experimental method improved the students success in learning the acids and bases subject significantly compared to the overall success of the students taught by the classical method . It did not, however, change the attitudes of the students to chemistry as indicated by the scores of the Chemistry Attitude Test (CAT) applied at the beginning and end of the study. There is no significant difference between groups . Key words : Chemistry, chemistry education, acids and bases
