- W2109703577 abstract "Summary: Science education can help people to understand the nature and utility of science, and contribute to developing informed and active citizen. Hence, the purpose of this study was to see if problem-based learning (PBL) in experimental vacation’ courses, with emphasis on the historical and epistemological foundations, could increase students’ understanding regarding nature of scientific knowledge. After initial strangeness, our study has shown that students usually rated high the opportunities that they had to plan and execute experiments of their own, instead of following cookbook recipes as usually happens in laboratory classes at school. Also, post-test scores were significantly higher than pretest scores on the total Nature of Scientific Knowledge Scale (NSKS), and on creative, testable, and unified NSKS subscales, indicating an improvement in the understanding of nature of scientific knowledge among school students. Of particular interest, the execution of practical activities in PBL form with ill-structured problems led a significant part of students to feel that they were creating and doing science. Therefore, the activities here proposed could be expanded as a form for improving the science education and to stimulate the formation of a new generation of creative scientists in Brazil." @default.
