Özet:

The aim of this study is to investigate the views of preservice science teachers on nature of science (NOS). A total of 166 preservice science teachers participated in the study. A 21-item أViews on Science-Technology-Society (VOSTS)ؤ instrument, translated and adapted into Turkish, were utilized to assess participants̕ views on the nature of science. The VOSTS (Aikenhead, Ryan and Fleming, 1989) is a pool of 114 empirically developed multiple-choice items with nine categories. In this study, 21 item selected from the epistemology of science category corresponded to the purposes of the assessment. In order to understand participants̕ views on nature of science in depth, semi-structured interviews were also conducted by 9 volunteer preservice science teachers. The results gave a picture of the preservice science teachers̕ views on nature of science. Results of this study revealed preservice science teachers̕ misconceptions on nature of science. Their views are mostly traditional on the nature of science. Results of the study indicated that preservice science teachers held traditional views (naive) regarding the definition of science; the nature of scientific models; the relationships between hypotheses, theories, and laws; fundamental assumptions for all science; the scientific method; uncertainty in scientific knowledge; epistemological status of scientific knowledge; coherence of concepts across disciplines. On the other hand participants have contemporary views (realistic) on the nature of observation; the nature of classification schemes; the tentativeness of scientific knowledge; cause and effect relationship. Analysis of interviews also supported these findings and gave a deep insight on preservice science teachers̕
