| Abstract | The purposes of this study were to extend the investigation concerning the limitations of quantitative data, explore the need for and use of qualitative data, and to evaluate two chemistry courses (CHEM Study and Modern Chemistry, 2nd edition). In his research, the investigator conducted a partial evaluation of these two courses and assessed the knowledge about science and scientists possessed by grade eleven and grade twelve students in Saskatchewan. Thirty-eight teachers were randomly selected to participate in the study; 28 agreed to do so. Student data were collected via the Nature of Science Scale--form SASK (NOSS), an instrument originally designed to assess the effect of university science programs on university students' understanding of the nature of science; the Science Process Inventory form D-SASK (SPI); and the Test on the Social Aspects of Science (TSAS) which deals with the interaction among science, technology and society. The use of t tests for matched pairs indicated that both chemistry courses had a negligible effect on students' knowledge about the scientific enterprise. Qualitative data revealed a balance between a gain in understanding and an acquisition of misconceptions. Also identified were specific ideas which indicated strengths and weaknesses in students' understanding about science and scientists. (PEB) |
