Perform or else: the performative enhancement of teacher professionalism

The Singapore Ministry of Education's Enhanced Performance Management System (EPMS) was instituted in 2005 as a system of professional accountability to enhance the standards and stakes of teacher professionalism in schools. This essay explores how the EPMS, with its underlying paradigm of performance management, functions as a “technology of discipline” within the political economy of teacher professionalization in Singapore. The analysis centres on the discursive mechanisms of a standardized appraisal instrument known as the Work Review Form. Applying speech act theory via the insights of J.L. Austin and J. Butler, I argue that teachers' professional qualities are not only described and prescribed but also produced by the appraisal protocols of the EPMS – a process contingent on the discursive performativity of the Work Review Form. Implicated in this notion of performativity are the rhetorical manoeuvres by which teachers perform “on paper” under the pressure to perform. Such performance pressures point to a range of ethical ambiguities surrounding the “enhanced management” of teachers' work under the profit-motive of performance excellence.     

Increasing international and domestic student interaction through group work: a case study from the humanities

This article explores the use of group work strategies to increase student interaction and learning. Despite the growing linguistic and cultural diversity in tertiary institutions, there is strong evidence of minimal interaction between ‘domestic’ and ‘international’ students in classrooms and in wider university contexts. This study investigates the implementation of teaching and learning strategies in an undergraduate class comprising domestic and international students from Education and Arts. The strategies relate to in-class group work, tutorial groups and assessment design. The findings indicate greater class interaction, higher satisfaction ratings and better learning outcomes as a result of the strategies. The article argues for three key features underpinning the pedagogy: where international students can work from a position of power equality in class, where both groups of students can enact the role of ‘experts’ and where support in language and learning how to learn is embedded in assessment and outcomes.     

Sexualities,teenage pregnancy and educational life histories in Portugal: experiencing sexual citizenship?

This article focuses on Portuguese working-class teenage girls’ voices and experiences concerning sexuality and pregnancy. Within a sociological, feminist and educational framework, it explores the girls’ perspective on sexual and intimate citizenship as evidence of fairer forms of regulation of teenage sexualities. Through building life histories of three pregnant and teenage mothers, this article aims to understand how girls rehearse and live out their sexualities and pregnancies as well as listen to their voices and recognise their demand for inclusion and respect. Gender power relations emerge as central in configuring girls’ pathways and shed light on youth pregnancy.     

Selected Physiological Responses of Normal Young Men following Dehydration and Rehydration

Abstract

This study was designed to compare man's normal working physiological performance to that during rapid dehydration and rehydration. Seven trained men participated in submaximal exercise trials at three conditions (normal, dehydrated, and rehydrated). During each test measurements were recorded on the subject's rectal temperature change during exercise and recovery, exercise and recovery minute heart rates, minute volume, oxygen consumption, respiratory quotient, ventilatory efficiency, and oxygen pulse. Analysis of the data, employing analysis of variance and Duncan's Multiple Range Test, indicated significant differences in mean exercise and second minute recovery heart rates, with an elevation during the dehydration test, and a return to normalcy for the rehydration test. Oxygen pulse decreased notably with dehydration, returning to normal with rehydration. Mean rectal temperature change, first minute recovery heart rate, oxygen consumption, ventilatory efficiency, minute volume, and respiratory quotient did not exhibit significant change.     

Developing and Assessing Curriculum on the Physics of Medical Instruments

Undergraduate educational settings often struggle to provide students with authentic biologically or medically relevant situations and problems that simultaneously improve their understanding of physics. Through exercises and laboratory activities developed in an elective Physics in Biomedicine course for upper-level biology or pre–health majors at Portland State University, we aim to teach fundamental physical concepts, such as light absorption and emission and atomic energy levels, through analysis of biological systems and medical devices. The activities address the properties of electromagnetic waves as they relate to the interaction with biological tissue and make links between physics and biomedical applications such as microscopy or laser eye surgery. We report on the effect that engaging students in tasks with actual medical equipment has had on their conceptual understanding of light and spectroscopy. These initial assessments indicate that students’ understanding improves in some areas as a result of taking the course, but gains are not uniform and are relatively low for other topics. We also find a promising “nonshift” in student attitudes toward learning science as a result of taking the course. A long-term goal of this work is to develop these materials to the extent that they can eventually be imported into an introductory curriculum for life sciences majors.     

From F = ma to Flying Squirrels: Curricular Change in an Introductory Physics Course

We present outcomes from curricular changes made to an introductory calculus-based physics course whose audience is primarily life sciences majors, the majority of whom plan to pursue postbaccalaureate studies in medical and scientific fields. During the 2011–2012 academic year, we implemented a Physics of the Life Sciences curriculum centered on a draft textbook that takes a novel approach to teaching physics to life sciences majors. In addition, substantial revisions were made to the homework and hands-on components of the course to emphasize the relationship between physics and the life sciences and to help the students learn to apply physical intuition to life sciences–oriented problems. Student learning and attitudinal outcomes were assessed both quantitatively, using standard physics education research instruments, and qualitatively, using student surveys and a series of postsemester interviews. Students experienced high conceptual learning gains, comparable to other active learning–based physics courses. Qualitatively, a substantial fraction of interviewed students reported an increased interest in physics relative to the beginning of the semester. Furthermore, more than half of students self-reported that they could now relate physics topics to their majors and future careers, with interviewed subjects demonstrating a high level of ability to come up with examples of how physics affects living organisms and how it helped them to better understand content presented in courses in their major.     

Stereotyped: Investigating Gender in Introductory Science Courses

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.
