Evaluating the reflexive practices in a learning experience

Reflexivity is a primary requirement for professional work. Our aim was to describe a methodology suitable for detecting the development of reflexive practice through the analysis of 59 Master’s degree students’ journals. We explore the use and changes of reflexive practice in relation to the settings and activities of the course using analysis of the mental language: We analyse how the reflexive practice is characterized, how it evolves through time and how it can be promoted. Data analysis shows that reflexivity is not monodimensional but multidimensional. Reflexive practice increases during the course: The different dimensions vary over time according to different organizational and educational conditions. This methodology allows us to formulate new hypotheses about which elements of the setting and process are effective in supporting participants’ reflexive practice.     

The quality of student dialogue in citizenship education

This study investigates the relationship between the quality of student dialogue and students’ ability to justify their viewpoints on a moral issue. A curriculum unit for dialogic citizenship education was developed and implemented in the 8th grade of secondary education. In the final lesson, students discussed a moral issue and then wrote an essay on it. The results show that students who made more value-related utterances during the discussion also referred more often and more explicitly in their individually written essays to moral values. This study indicates that the quality of the content of students’ dialogue is important for their ability to substantiate their opinion on moral issues with value-laden argumentation. Approaches to citizenship education in which dialogue is a central element should, therefore, pay specific attention to the validation of ideas in student dialogue.     

The value and valuing of continuing professional development: current dilemmas,future directions and the case for action research

This paper explores and challenges the rationale for current, mainstream approaches to teachers’ continuing professional development (CPD) within schooling systems. Such approaches are significantly influenced by neoliberal and managerial pressures, evident in advocacy for generic, individualistic models of teacher learning, often focused on specific state-sanctioned domains. The paper draws upon a précis of recent action research literature, and empirical research from Sweden, to argue for an alternative paradigm, based on the practices and principles of participatory and collaborative action research. Action research is not presented as a simplistic ‘method’ which can be ‘applied’ regardless of context, but is explicitly focused on situated, specific, local sites. While more managerial and neoliberal practices can close down debates necessary for effecting real improvements in practice, evidence suggests action research, in its emancipatory iterations, enables a rich conception of educational practice which cannot be ‘managed’ into existence by a simplistic application of ‘what works.’     

Measuring the Diversity Inclusivity of College Courses

Most studies of curricular diversity have focused on the effects of participation in diversity courses on student outcomes. Though the results have been positive, these studies have used limited measures of curricular diversity and there is a great need for a complimentary body of research demonstrating what faculty and what types of courses are more likely to include diversity. This study relies on 12 diversity inclusivity items derived from a comprehensive model of how diversity is included into a course to investigate how much diversity is being included in collegiate courses and what predicts diversity inclusivity, as measured by two scales: diverse grounding and inclusive learning. The results, based on 7,101 responses from faculty participating in the 2007 Faculty Survey of Student Engagement, suggest that most faculty are including diversity in their courses in some way, but that women and faculty of color tend to include diversity to a greater extent than their colleagues. Also, courses taught in the soft fields are more likely to be inclusive of diversity.     

Acting White: A Critical Review

The hypothesis of acting White has been heatedly debated and influential over the last 20 years or so in explaining the Black–White test score gap. Recently, economists have joined the debate and started providing new theoretical and empirical analyses of the phenomenon. This paper critically reviews the arguments that have been advanced to support and refute the hypothesis. This review particularly covers the analyses in economics because the economic analyses are relatively new and usually neglected in other disciplines. Also, nationally representative data are emphasized, whenever possible, to improve the generalizability of the arguments. This review concludes that although the analyses in both non-economics and economics are thought-provoking and compelling in some respect, a substantial body of empirical evidence is inconsistent with the assumptions of and results from the analyses.     

Engineering the race car wing: application of the vortex panel numerical method

This study examined aerodynamic properties and boundary layer stability in five cambered airfoils operating at the low Reynolds numbers encountered in motor racing. Numerical modelling was carried out in the flow regime characterised by Reynolds numbers 0.82–1.29 × 10⁶. The design Reynolds number of 3 × 10⁶ was used as a reference. Aerodynamics variables were computed using AeroFoil 2.2 software, which uses the vortex panel method and integral boundary layer equations. Validation of AeroFoil 2.2 software showed very good agreement between calculated aerodynamic coefficients and wind tunnel experimental data. Drag polars, lift/drag ratio, pitching moment coefficient, chordwise distributions (surface velocity ratio, pressure coefficient and boundary layer thickness), stagnation point, and boundary layer transition and separation were obtained at angles of attack from −4° to 12°. The NASA NLF(1)-0414F airfoil offers versatility for motor racing with a wide low-drag bucket, low minimum profile drag, high lift/drag ratio, laminar flow up to 0.7 chord, rapid concave pressure recovery, high resultant pressure coefficient and stall resistance at low Reynolds numbers. The findings have implications for the design of race car wings.
