The main aim of this study to investigate the effectiveness of conceptual change texts oriented instruction accompanied with analogies over traditionally designed chemistry instruction on overcoming 10th grade students& / #8217 / misconceptions, their understanding of rate of reaction concepts and attitude towards chemistry as a school subject.
56 tenth grade students from two classes of a chemistry course taught by the same teacher in the ATATÜ / RK Anatolian High school, participated in the study. This study was carried out in 2003-2004 spring semester.
There were two groups in the study. Experimental group was instructed with conceptual change texts oriented instruction accompanied with analogies and the control group was instructed by traditionally designed chemistry instruction over a period of four weeks.
To investigate the effect of treatment, Rate of Reaction Concepts Test and Attitude Scale Toward Chemistry as a school subject were administered to all students in both groups at the beginning and end of the treatment. To evaluate students& / #8217 / science process skills, Science Process Skills Test was administered before treatment.
To test the hypothesis of the study ANOVA and ANCOVA were used. The result of the study showed that students in conceptual change texts oriented instruction accompanied with analogies got higher average scores in Rate of Reaction Concepts Test than traditionally designed chemistry instruction. Also, students in experimental group indicated a higher positive attitude toward chemistry as a school subject. In addition, science process skill was a strong predictor for the achievement related to rate of reaction concepts.
Results and strategies that were developed for this study may be used by teachers to reduce and eliminate students& / #8217 / misconceptions about the rate of reaction concepts.
