| Popis: | EFFECTIVENESS OF CONCEPTUAL CHANGE INSTRUCTION ACCOMPANIED WITH DEMONSTRATIONS AND COMPUTER ASSISTED CONCEPT MAPPING ON STUDENTS&rsquo UNDERSTANDING OF MATTER CONCEPTS Yavuz, Ayse PhD., Department of Secondary Science and Mathematics Education Supervisor: Prof. Dr. Ö mer Geban January 2005, 133 pages The main purpose of this study was to investigate the effectiveness of conceptual change instruction accompanied with demonstration and computer assisted concept mapping on seventh grade students understanding matter concepts. In addition, the effect of instruction on students&rsquo attitudes toward science as a school subject and the effect of gender difference on understanding matter concepts were investigated. Seventy five, seventh grade students from four classes of a General Science Course taught by the same teacher at Ö zel ENKA Middle School during fall semester of 2003&ndash 2004 was enrolled in this study. The classes were randomly assigned as conrol group and experimental group. Students in the control group received traditional science instruction including traditional lecture method with discussions and traditionally designed labsheets. Students who were in the experimental group received conceptual change instruction accompanied with demonstration and computer assisted concept mapping. Both groups were administered Matter Concept Test as pre- and post-tests and Attitude Scale toward Science as a School Subject. In addition to these, Science Process Skill Test was used at the beginning of the study to determine students&rsquo science process skills. T-test, univariate analysis of variance (ANOVA) and analysis of covariance (ANCOVA) were used for testing the hypotheses of the study. The results indicated that conceptual change instruction accompanied with demonstration and computer assisted concept mapping caused a better acquisition of scientific conceptions related to matter concepts and produced more positive attitudes toward science as a school subject than traditionally designed sicence instruction. In addition, science process skill was a strong predictor in understanding matter concepts. On the other hand, no significant effect of gender difference on students&rsquo understanding of matter concepts and their attitudes toward science as a school subject was found. |
