Formative assessment has been recognised as a critical element in teaching for conceptual development. A case study research design was employed to: (1) characterise the assessment thinking of three science instructors at a research‐based university; and (2) examine the complex relationship between instructor thinking and practice by encouraging experimentation with alternative assessment strategies. Interviews, reflective journals, field notes and course documents were the data sources used to create a single case study that documented the development of these university instructors’ assessment thinking during their experimentation with formative assessment strategies. Throughout two semesters of experimentation, the instructors’ assessment thinking became more sophisticated; they grew to view the purpose of assessment less as a summative activity used for the assignment of marks and more as a tool for diagnosing student learning. However, more sophisticated thinking was not associated with revisions in teaching practice based on formative assessment data. Further investigations are needed to more completely understand the nature of assessment thinking and how assessment thinking influences assessment practices. Implications for professional development of university‐level science instructors include personalised experiences through which instructors can become active participants in gathering evidence of student learning that promotes growth in assessment thinking. 相似文献

Science educators have the common goal of helping students develop scientific literacy, including understanding of the nature of science (NOS). University faculties are challenged with the need to develop informed NOS views in several major student subpopulations, including science majors and nonscience majors. Research into NOS views of undergraduates, particularly science majors, has been limited. In this study, NOS views of undergraduates in introductory environmental science and upper-level animal behavior courses were measured using Likert items and open-ended prompts. Analysis revealed similarities in students'' views between the two courses; both populations held a mix of naïve, transitional, and moderately informed views. Comparison of pre- and postcourse mean scores revealed significant changes in NOS views only in select aspects of NOS. Student scores on sections addressing six aspects of NOS were significantly different in most cases, showing notably uninformed views of the distinctions between scientific theories and laws. Evidence-based insight into student NOS views can aid in reforming undergraduate science courses and will add to faculty and researcher understanding of the impressions of science held by undergraduates, helping educators improve scientific literacy in future scientists and diverse college graduates. 相似文献

Research in science education has documented achievement gaps between men and women in math and physics that may reflect, in part, a response to perceived stereotype threat. Research efforts to reduce achievement gaps by mediating the impact of stereotype threat have found success with a short values-affirmation writing exercise. In biology and biochemistry, however, little attention has been paid to the performance of women in comparison with men or perceptions of stereotype threat, despite documentation of leaky pipelines into professional and academic careers. We used methodologies developed in physics education research and cognitive psychology to 1) investigate and compare the performance of women and men across three introductory science sequences (biology, biochemistry, physics), 2) document endorsement of stereotype threat in these science courses, and 3) investigate the utility of a values-affirmation writing task in reducing achievement gaps. In our study, analysis of final grades and normalized learning gains on content-specific concept inventories reveals no achievement gap in the courses sampled, little stereotype threat endorsement, and no impact of the values-affirmation writing task on student performance. These results underscore the context-dependent nature of achievement gaps and stereotype threat and highlight calls to replicate education research across a range of student populations. 相似文献
