Teachers using annotations to engage students in assessment conversations: recontextualising knowledge

Assessment for Learning practices with students such as feedback, and self- and peer assessment are opportunities for teachers and students to develop a shared understanding of how to create quality learning performances. Quality is often represented through achievement standards. This paper explores how primary school teachers in Australia used the process of annotating work samples to develop shared understanding of achievement standards during their curriculum planning phase, and how this understanding informed their teaching so that their students also developed this understanding. Bernstein's concept of the pedagogic device is used to identify the ways teachers recontextualised their assessment knowledge into their pedagogic practices. Two researchers worked alongside seven primary school teachers in two schools over a year, gathering qualitative data through focus groups and interviews. Three general recontextualising approaches were identified in the case studies; recontextualising standards by reinterpreting the role of rubrics, recontextualising by replicating the annotation process with the students and recontextualising by reinterpreting practices with students. While each approach had strengths and limitations, all of the teachers concluded that annotating conversations in the planning phase enhanced their understanding, and informed their practices in helping students to understand expectations for quality.     

Judging Words by Their Covers and the Company They Keep: Probabilistic Cues Support Word Learning

Statistical learning may be central to lexical and grammatical development. The phonological and distributional properties of words provide probabilistic cues to their grammatical and semantic properties. Infants can capitalize on such probabilistic cues to learn grammatical patterns in listening tasks. However, infants often struggle to learn labels when performance requires attending to less obvious cues, raising the question of whether probabilistic cues support word learning. The current experiment presented 22‐month‐olds with an artificial language containing probabilistic correlations between words' statistical and semantic properties. Only infants with higher levels of grammatical development capitalized on statistical cues to support learning word‐referent mappings. These findings suggest that infants' sensitivity to correlations between sounds and meanings may support both word learning and grammatical development.     

Changing Schools of Education Through Grassroots Faculty-led Change

In this article I report on the application of the lens of Rogers’ (1995) change agent roles and Kezar and Lester’s (2011) adaptation of tempered radicals in order to understand the leadership roles assumed by three individual faculty members located at three distinct schools of education. These faculty leaders utilized the concepts and principles of the Carnegie Project on the Education Doctorate (CPED) to lead redesigns of their Ed.D. programs. Qualitative data were gathered during a larger study on institutional change. Findings contribute to understanding grassroots leadership and how it works in collaboration with top-down authorities.     

Mediation analysis of an adolescent HIV/STI/pregnancy prevention intervention

Most interventions designed to prevent HIV/STI/pregnancy risk behaviours in young people have multiple components based on psychosocial theories (e.g. social cognitive theory) dictating sets of mediating variables to influence to achieve desired changes in behaviours. Mediation analysis is a method for investigating the extent to which a variable X (e.g. intervention indicator) influences an outcome variable Y (e.g. unprotected sex) by first influencing an intermediate variable M (e.g. self-efficacy to use a condom) and provides a way for empirically validating theoretical hypothesised mediators. In this way, mediation analysis is a critical tool for suggesting which components of complex interventions should be the focus of more efficient and effective interventions in the future. The present study applied multilevel mediation analysis to outcome data from the All4You2! study to begin to examine the relationships between a theory-based HIV/STI/pregnancy prevention curriculum for students attending alternative high schools who were at risk of educational failure. The study targeted psychosocial mediating variables and the primary outcome unprotected sex in the past three months. Results suggest helping young people attending alternative schools identify and avoid exposure to risky situations and improving their self-efficacy to refuse sex should be focal points of future interventions.     

Romantic relationships: an important context for HIV/STI and pregnancy prevention programmes with young people

Romantic relationships are central in the lives of young people. This paper uses data on romantic relationships from urban youth in the USA to illustrate how using a relationships perspective in HIV/STI and pregnancy prevention programmes broadens the skills and content covered, and contextualises the learning to enhance relevance and use. Self-report survey data were collected using electronic handheld devices for a school-based randomised trial. The survey sample includes 911 young people (mean age = 12.4 years) representative of their schools. Logistic regressions explored associations between selected sexual behaviours and relationship characteristics. For all participants, having more boy/girlfriends, dating alone, ever touching and ever having had oral sex were associated with an increased likelihood of having vaginal sex. Among young people with current partners, having a partner three or more years older, length of relationship and ever having oral sex were associated with an increased likelihood of having vaginal sex. The study data confirm the importance of accounting for relationships in sexual risk reduction programmes, and provide avenues for enhancing the relevancy of typical school-based prevention programmes.     

Examining the Moderating Effect of Appearance Impression Motivation on the Relationship Between Perceived Physical Appearance and Social Physique Anxiety

We measured the effects of stride rate, resistance, and combined arm-leg use on energy expenditure during elliptical trainer exercise and assessed the accuracy of the manufacturer's energy expenditure calculations. Twenty-six men and women (M age = 29 years, SD = 8; M body weight = 73.0 kg, SD = 15.2) participated. Twenty-two participants performed two tests, one without the arm poles (leg-only) and the other with arm poles (combined arm-leg). The other 4 participants performed one test without the arm poles. Both tests consisted of six 5-min stages (two stride rates, 110 and 134 strides^.min^-1, and three resistance settings: 2, 5, and 8). Steady-state oxygen uptake (VO₂), minute ventilation (VE), heart rate (HR) and rating of perceived exertion (RPE) were measured. Repeated measures analysis of variance determined higher (p < .001) VO₂, VE, and RPE, but not HR, during combined arm-leg versus leg-only exercise at any given intensity. Increases in stride rate and resistance increased VO₂, VE, RPE, and HR with the greatest effect on VE and HR from Levels 5 to 8. The manufacturer's calculated energy expenditure was overestimated during both tests. Although the oxygen cost for elliptical trainer exercise was calculated to be approximately 0.1 ml^.kg^-1 per stride and 0.7 ml^.kg^-1.min^-1 per resistance level, VO₂ varied widely among individuals, possibly due to differences in experience using the elliptical trainer, gender, and body composition. The elliptical trainer offers (a) a variety of intensities appropriate for most individuals and (b) both arm and leg exercise. Due to the wide variability in VO₂, predicting the metabolic cost during elliptical trainer exercise for an individual is not appropriate.     

Validity of Activity Trackers in Estimating Energy Expenditure During High-Intensity Functional Training

ABSTRACT

Purpose: The purpose of this study was to evaluate the agreement of five commercially available accelerometers in estimating energy expenditure while performing an acute bout of high-intensity functional training (HIFT). Methods: Participants (n = 47; average age: 28.5 ± 11.6 years) consisted of recreationally active, healthy adults. Each participant completed a session of HIFT: a 15-minute workout consisting of 12 repetitions each of air-squats, sit-ups, push-ups, lunges, pull-ups, steps-ups, and high-knees; performed circuit-style by completing as many rounds as possible. During this session, each participant wore the Cosmed K4b2 portable metabolic analyzer (PMA) and five different accelerometers (ActiGraph GT3X, Nike Fuelband, Fitbit One, Fitbit Charge HR, and Jawbone UP Move). Results: Four of the five activity trackers reported lower (p < .05) total EE values compared to the PMA during the acute bout of HIFT. The waist-mounted device (ActiGraph, 182.55 ± 37.93 kcal) was not significantly different from, and most closely estimated caloric expenditure compared to the PMA (144.99 ± 37.13 kcal) (p = .056). A repeated-measures ANOVA showed that all activity trackers were significantly different from the reference measure (PMA) (p < .05). Systematic relative agreement between the activity trackers was calculated, exhibiting a significant ICC = 0.426 (F [46,230] = 5.446 [p < .05]). Conclusion: The wrist- and hip-mounted activity trackers did not accurately assess energy expenditure during HIFT exercise. With the exception of the ActiGraph GT3X, the remaining four activity trackers showed inaccurate estimates of the amount of kilocalories expended during the HIFT exercise bout compared to the PMA.     

Leadership Values,Trust and Negative Capability: Managing the Uncertainties of Future English Higher Education

The complex leadership attribute of ‘negative capability’ in managing uncertainty and engendering trust may be amongst the qualities enabling institutions to cope with multiple recent government policy challenges affecting English higher education, including significant increases in student fees. Research findings are reported on changes in leadership values, trust and organisational cultures in higher education during the current ‘age of austerity’. Data from university experts, managers and academics in semi‐structured interviews were informed by questionnaires (n = 16), online surveys (n = 121) and a focus group (n = 6). Findings indicated that values‐based leadership characterised by skilful ‘negative capability’ is now needed in English higher education. ‘Negative capability’ is defined as the ability to resist the ‘false necessity’ of deterministic solutions in building staff trust to cope proactively with ambiguity and change. This capability is needed for academic leaders to maintain their role in shaping the enduring purposes of higher education during a recession, both in England and in the wider international environment.     

Globalisation and the Restructuring of Higher Education for New Knowledge Economies: New Dangers or Old Habits Troubling Gender Equity Work in Universities?

This article undertakes a feminist critique of the restructuring of the modern university in Australia. It considers the interaction of the processes of globalisation, corporatisation (through the twin strategies of marketisation and managerialism) and the social relations of gender, and their implication for gender equity work in the academy. The paper locates the reform of Australian universities within their Western context, and considers the gendered effects of the new disciplinary technologies of quality assurance and online learning on the position of women academics. It concludes with some comments about the shift in language from equity to diversity which has accompanied corporatisation, and how this has effectively coopted women's intellectual labour to do the work of the entrepreneurial university.     

The C3 Framework: Evaluating Classroom Response System Interactions in University Classrooms

The larger the classroom, the more likely is it that communications consist of a one-way flow from the instructor to students. Classroom Response Systems (CRSs) are frequently hailed as technologies capable of improving communications by opening the space for dialogic engagement; yet, a causal relationship is not documented in the literature. The data reported on here stem from a mixed methodology study and provide insights into motivations for CRS use and enacted CRS use across disciplines, as well as student and instructor perceptions of the tool’s effects on teaching and learning. From these data emerged a framework of interaction (the C³ Framework) that situates CRS use from both the instructors’ and learners’ perspectives. The framework consists of an interdependent relationship between Concerns, Centeredness, and Control of discourse. Although this study took place in university classrooms, the C³ Framework presented here applies across educational settings.
