| Popis: | The goal of this study was to investigate the nature of questions that elicit responses in particulate terms. Four additional questions were developed with a gradation of scientific content between the everyday and scientific questions used by Haidar and Abraham in their Physical Changes Concepts Test (PCCT). The concepts tested were dissolution, insolubility, saturation, diffusion, states of matter, and effusion. Each of the approximately 1066 freshman chemistry students was administered a test form via the Internet, which progressed from everyday to scientific content and randomly covered all six concepts. No strong correlations were found between the students' logical reasoning ability and their use of particulate terminology. None of the concepts in this study showed a high percentage of completely correct responses using the particulate theory. However, the study did find that students are immediately cued by the words in the questions, whether in everyday or scientific terms. The findings indicate t... |
