Özet:The purpose of this study was to compare the effectiveness of the conceptual change oriented instruction using hands-on activities and traditionally designed chemistry instruction on 10th grade students’ understanding of gases concept. Also, the effect of instruction on students’ attitude toward chemistry as a school subject was investigated. The sample of the study consisted of 59 tenth grade students from two chemistry classes in a public high school. This study was conducted during the 2006-2007 fall semester. The classes were randomly assigned as control and experimental groups. Students in the control group were instructed by traditionally designed chemistry instruction whereas students in the experimental group were instructed by the conceptual change oriented instruction accompanied with hands-on activities. Gases concept test and Attitude Scale Toward Chemistry were administered to both groups as a pre-test and post-test to assess the students’ understanding of gases concepts and to determine their attitudes toward chemistry, respectively. Science Process Skills Test was given only at the beginning of the instruction to determine students’ science process skills. v The hypotheses were tested by using multivariate analysis of variance (MANOVA). The post-test results showed that conceptual change oriented instruction using hands-on activities caused a significantly better acquisition of scientific conceptions related to gases concept. But it was found that treatment has no significant effect on students’ attitudes toward chemistry as a school subject.
