Implementing Criterion-referenced Assessment Within a Multi-disciplinary University Department

This paper is concerned with the reconstruction, at the departmental level, of a university assessment policy that required a shift from norm-referenced assessment to criterion-referenced assessment (CRA). As such, it provides an account of a change process driven by a centralised policy imperative and yet implemented and driven also from a bottom-up process. A wide range of data was gathered using action research methods. Individual and focus group interviews were conducted with staff and students, participant journals were kept and successive drafts of criteria and standards, and samples of students' responses were collected. The data suggested that a top-down policy can be successfully combined with a departmental-driven process, if financial and time considerations are addressed and a collaborative process amongst staff is sustained. The use of action learning, as a tool for change, appeared to assist participants to begin to own a top-down policy.     

Quantification of maximal power output in well-trained cyclists

ABSTRACT

This study aimed to compare mechanical variables derived from torque-cadence and power-cadence profiles established from different cycle ergometer modes (isoinertial and isokinetic) and modelling procedures (second- and third-order polynomials), whilst employing a novel method to validate the theoretical maximal power output (P_max). Nineteen well-trained cyclists (n = 12 males) completed two experimental sessions comprising six, 6-s maximal isoinertial or isokinetic cycling sprints. Maximal pedal strokes were extracted to construct power–cadence relationships using second- and third-order polynomials. A 6-s sprint at the optimal cadence (F_opt) or optimal resistance (T_opt) was performed to assess construct validity of P_max. No differences were found in the mechanical parameters when derived from isokinetic (P_max = 1311 ± 415, F_opt = 118 ± 12) or isoinertial modes (P_max = 1320 ± 421, F_opt = 116 ± 19). However, R² improved (P < 0.02) when derived from isoinertial sprints. Third-order polynomial modelling improved goodness of fit values (Standard Error, adjusted R²), but derived similar mechanical parameters. Finally, peak power output during the optimised sprint did not significantly differ from the theoretical P_max in both cycling modes, thus providing construct validity. The most accurate P-C profile can be derived from isoinertial cycling sprints, modelled using third-order polynomial equations.     

Integrating inquiry science and language development for English language learners

The traditional approach to the education of language minority students separates English language development from content instruction because it is assumed that English language proficiency is a prerequisite for subject matter learning. The authors of this article take the alternate view that the integration of inquiry science and language acquisition enhances learning in both domains. The report describes a conceptual framework for science–language integration and the development of a five‐level rubric to assess teachers' understanding of curricular integration. The science–language integration rubric describes the growth of teacher expertise as a continuum from a view of science and language as discreet unrelated domains to the recognition of the superordinate processes that create a synergistic relationship between inquiry science and language development. Examples from teacher interviews are used to illustrate teacher thinking at each level. © 2002 Wiley Periodicals, Inc. J Res Sci Teach 39: 664–687, 2002     

Wiki Laboratory Notebooks: Supporting Student Learning in Collaborative Inquiry-Based Laboratory Experiments

Recent examples of high-impact teaching practices in the undergraduate chemistry laboratory that include course-based undergraduate research experiences and inquiry-based experiments require new approaches to assessing individual student learning outcomes. Instructors require tools and strategies that can provide them with insight into individual student contributions to collaborative group/teamwork throughout the processes of experimental design, data analysis, display and communication of their outcomes in relation to their research question(s). Traditional assessments in the form of laboratory notebooks or experimental reports provide limited insight into the processes of collaborative inquiry-based activities. A wiki environment offers a collaborative domain that can potentially support collaborative laboratory processes and scientific record keeping. In this study, the effectiveness of the wiki in supporting laboratory learning and assessment has been evaluated through analysis of the content and histories for three consenting, participating groups of students. The conversational framework has been applied to map the relationships between the instructor, tutor, students and laboratory activities. Analytics that have been applied to the wiki platform include: character counts, page views, edits, timelines and the extent and nature of the contribution by each student to the wiki. Student perceptions of both the role and the impact of the wiki on their experiences and processes have also been collected. Evidence has emerged from this study that the wiki environment has enhanced co-construction of understanding of both the experimental process and subsequent communication of outcomes and data. A number of features are identified to support success in the use of the wiki platform for laboratory notebooks.     

Muscularity,the Habitus and the Social Construction of Gender: Towards a gender-relevant physical education

This paper begins to develop the concept of gender-relevant physical education, combining the work of Pierre Bourdieu and his notion of the habitus and feminist philosopher Iris Marion Young's analysis of feminine motility. It draws on data generated from a study of young people's articulation of the relationships between muscularity, physicality and gender. The social construction of the body has been of central importance to the construction of femininities and masculinities, and has formed an enduring meta-theme through much of the research on physical education and gender. We build on the young people's insights to argue that Bourdieu's notions of the habitus and the exchange of physical capital provide a useful means of conceptualizing issues of embodiment and gender in school physical education and sport. We conclude by sketching an outline of gender-relevant physical education as a process of interrupting the habitus.
