Accountability and the affective labour of teachers: a Marxist–Vygotskian perspective     

Alex Kostogriz 《The Australian Educational Researcher》2012,39(4):397-412

This article addresses the issue of affective labour in education in the context of standards-based reforms and accountability. In particular, it focuses on neoliberal strategies of rationalization and control that produce a number of social pathologies, such as alienated teaching and learning and reified social relations between teachers and students. The article turns to affective labour as something that enables teachers to counteract these effects. This argument arises from the analysis of interviews with teachers who continue to generate and sustain the sociality of teaching and learning. Affect directs teachers?? commitment to practice that is governed by feeling, passion and the ethics of care. What gives affective labour such an important position is that it is both outside and beyond accountability and performativity measures. It is identified with the general pedagogical activity that cannot be structured by measuring devices such as students?? test scores or standards. The article concludes with the application of Vygotsky??s ideas about the role of affect in education and argues that affective labour has an expansive power of ontological freedom that cannot be controlled.  相似文献

Thinking Spatially: Teaching an Undervalued Practice Skill     

Sue Steiner  M. Alex Wagaman  Pravina Lal 《Journal of Teaching in Social Work》2013,33(4):427-442

Spatial thinking, which is taught and practiced in many of the social sciences, is a skill that is often overlooked in the social work curriculum. Spatial thought increases perception, logic, and organized cognition of goals and therefore holds promise for social work practice. Developing skills in spatial thought offers social workers additional tools for problem solving at all practice levels. Finally, thinking spatially raises awareness of problem-solving techniques in relation to environmental resources, a key aspect of systems theory. Fortunately, spatial thinking can be easily integrated into a variety of social work classes helping students master the skill and understand its importance. This article defines and describes spatial thinking, explores its fit in various areas of the social work curriculum, and discusses ways its use can be encouraged.  相似文献   

Direct Instruction Microcomputing in Primary Schools: manipulation of critical instructional variables     

Amanda Gelder  Alex Maggs 《Research in Science & Technological Education》2013,31(2):221-238

This article reports on a study carried out into the relationships between the component skills involved in practical work assessment. The skills concerned are observing, manipulating, planning, interpreting, reporting and self‐reliance. The literature relating to inter‐skill relationships is reviewed. Data derived from the study suggest that interpretation and planning skills are strongly related to one another, whereas performance on reporting, observation and self‐reliance skills are relatively distinct, both from one another and from all other component skills.  相似文献   

A DIALOGICAL APPROACH TO CRITICAL BIBLE STUDY: THE USE OF SCHWABIAN DELIBERATION TO INTEGRATE THE WORK OF BIBLE SCHOLARS WITH EDUCATIONAL PHILOSOPHY   总被引：1，自引：0，他引：1  

Alex Sinclair 《Religious education (Chicago, Ill.)》2013,108(2):107-124

This article uses analytic tools provided by Joseph Schwab to address a “practical” problem faced by many liberal religious educational institutions: the tension between historical-critical study of the Bible and an affective connection to it. This problem is painted in broad strokes; then two contemporary Bible scholars, Jeffrey Tigay and Yair Zakovitch, are analyzed for the “principles of enquiry” used in their disciplinary orientations. This analysis is merged with a dialogical hermeneutics approach to text, using the work of Kepnes, Buber, and Gadamer. The article concludes by considering how this study might inform Bible curricula in liberal religious educational contexts.  相似文献   

Cascade optical chromatography for sample fractionation     

Alex Terray  Joseph D. Taylor    Sean J. Hart 《Biomicrofluidics》2009,3(4)

Optical chromatography involves the elegant combination of opposing optical and fluid drag forces on colloidal samples within microfluidic environments to both measure analytical differences and fractionate injected samples. Particles that encounter the focused laser beam are trapped axially along the beam and are pushed upstream from the laser focal point to rest at a point where the optical and fluid forces on the particle balance. In our recent devices particles are pushed into a region of lower microfluidic flow, where they can be retained and fractionated. Because optical and fluid forces on a particle are sensitive to differences in the physical and chemical properties of a sample, separations are possible. An optical chromatography beam focused to completely fill a fluid channel is operated as an optically tunable filter for the separation of inorganic, polymeric, and biological particle samples. We demonstrate this technique coupled with an advanced microfluidic platform and show how it can be used as an effective method to fractionate particles from an injected multicomponent sample. Our advanced three-stage microfluidic design accommodates three lasers simultaneously to effectively create a sequential cascade optical chromatographic separation system.  相似文献   

Persistent heterogeneity of R&D intensities within sectors: Evidence and policy implications     

Alex Coad 《Research Policy》2019,48(1):37-50

Do firms in the same sector converge towards the same R&D intensities? Previous research has often assumed this to be true. A closer examination, using microdata from the EU Industrial R&D Investment Scoreboard for the years 2000–2015, shows considerable heterogeneity in R&D intensities among firms in the same sector, and that this heterogeneity persists over time. Statistical tests of convergence show that the variation in R&D intensities does not decrease over time (i.e. no σ-convergence), although firms with an R&D intensity below the industry average do seem to catch up with the leaders (i.e. evidence of β-convergence). Overall, firms in the same industry do not converge to a common R&D intensity. Policy implications are discussed.  相似文献   

An investigation of the accuracy and reliability of body composition assessed with a handheld electrical impedance myography device     

Cherilyn N. McLester  Alex D. Dewitt  Rasmus Rooks  John R. McLester 《European Journal of Sport Science》2018,18(6):763-771

The purpose of this study was to compare the body fat per cent (BF%) assessed with a unique handheld electrical impedance myography (EIM) device, along with other popular methods, to dual-energy X-ray absorptiometry (DXA). Participants included 33 males (aged 24.3?±?4.6 years) and 38 females (aged 25.3?±?8.9 years) who completed 2 visits separated by 24–72?h. The assessments included DXA, bioelectrical impedance analysis (BIA), skinfold measures (SKF), and three separate EIM measurements. No significant differences in BF% (P?>?0.05) were found between all EIM assessments when compared against DXA for both males and females for each visit. All methods showed no significant differences in BF% (P?>?0.05) between days within themselves. Across both days, the standard error of the estimate (SEE) for the EIM measurements ranged from 2.66% to 3.15%, the SEE for BIA was 2.80 and 2.85, and for SKF was 2.90 and 2.82. The 95% limits of agreement ranged from ±5.34% to ±6.38% for EIM measurements and were highest for SKF (±7.42% and ±7.47%). The total error for both days was largest for SKF (5.20% and 5.35%) and lowest for the EIM measurements (2.48–3.24%). This investigation supports use of a handheld EIM device as an accurate and reliable method of estimating BF% compared to DXA in young, apparently healthy individuals with BF% in the range of 10–22% for males and 20–32% in females and suggests this EIM device be considered a viable alternative to other established field measurements in this population.  相似文献   

High-school students' need for cognition,self-control capacity,and school achievement: Testing a mediation hypothesis     

Alex Bertrams  Oliver Dickhäuser 《Learning and individual differences》2009,19(1):135-138

In the present article, we examine the hypothesis that high-school students' motivation to engage in cognitive endeavors (i.e., their need for cognition; NFC) is positively related to their dispositional self-control capacity. Furthermore, we test the prediction that the relation between NFC and school achievement is mediated by self-control capacity. A questionnaire study with grade ten high-school students (N = 604) revealed the expected relations between NFC, self-control capacity, and school achievement. Sobel tests showed that self-control capacity mediated the relation between NFC and school grades as well as grade retention.  相似文献
