Using the theory of successful intelligence as a framework for developing assessments in AP physics

A new test of Advanced Placement Physics, explicitly designed to balance both content and cognitive-processing skills, was developed using Sternberg’s theory of successful intelligence. The test was administered to 281 AP Physics students from 10 schools during the 2006–2007 school year. Six empirically distinguishable profiles of strengths and weaknesses emerged from an exploratory Q-type factor analysis across the four cognitive-skill areas assessed (i.e., memory, analytical, creative, and practical skills). These profiles replicated those found in previous research in the domains of AP Psychology and AP Statistics. Furthermore, achievement differences between ethnic groups on various cognitive subscales were reduced as compared with traditional estimates. The results provide evidence of the importance of integrating modern theories of cognitive processing into large-scale assessments.     

Teaching the Alphabet: Reconciling the Past and the Present

This guest editorial focuses on a reflective journey of two early childhood professionals as student and teacher turning into classroom teacher and literacy coach. In addition, this editorial explores some of the worries the classroom teacher expressed during a reflective journey in learning ways in which to teach alphabet letter recognition that increased child outcomes.     

Identifying high-quality centre-based childcare using quantitative data-sets: what the numbers do and don't tell us

Quantitative approaches to defining and measuring quality in early childhood education and care (ECEC) have provided a key platform for policy development. Yet their strengths and limitations as informants of high-quality ECEC have not been tested. In this study we examine two sources of quantitative data collected over a five-year period for 74 long day care centres: (1) the Early Childhood Environment Rating Scale-Revised and Infant-Toddler Environment Rating Scale instruments which are well-established observational measures; and (2) Australia's nationally administered Quality Improvement and Accreditation System which involves a self-study and validation process. Correspondence over time and across measures was more consistent for the centres identified as providing lower quality ECEC. Variability in ratings of quality was more evident in lower quality centres, whereas high-quality centres showed less variability over time. High quality, however, was less consistently identified across measures. Discussion focuses on the strengths and limitations of these measures of quality, and the implications these have for policy development and future research.     

HPT roots and branches: Analyzing over 45 years of the field's own citations. Part 3: Author citations

This is the third and final article in a series of three that reviews the citation patterns of references cited in the entire collection of International Society for Performance Improvement journal articles (1962–2007) and all chapters published in the three human performance technology handbooks (Pershing, 2006; Stolovitch & Keeps, 1992, 1999). The first article (Huglin, 2009a) reported on the journal articles cited most frequently in this collection; the second article (Huglin, 2009b) provided an analysis of books and book chapters cited, including which books are cited most frequently, both overall and by decade. This article reports on the most cited authors: overall, by type of reference, and by decade.     

A comparison of the anticipated benefits and received outcomes of pediatric cochlear implantation: parental perspectives

Findings of a study that investigated parents' expectations and experiences of their children's outcomes with cochlear implants are presented. A survey completed by 247 parents whose children had received implants in eastern Australia compared parents' reports of their preimplant expectations with their experiences of postimplant outcomes on several items related to communication, academic, and psychosocial domains. Quantitative findings derived from the survey data were extended and elaborated on by qualitative findings from interviews with 27 of the parents. The findings indicated that parents' relatively high expectations of their children's outcomes largely had been met, although a tenth of survey respondents reported that their expectations had not been met. It appeared that professionals generally provided parents with realistic expectations. The qualitative findings revealed a complex interaction among parents' expectations, hopes, and determination that their children would do well with the implant. Implications for professionals are discussed.     

Leading Developmental Peer Observation of Teaching in Higher Education: Perspectives from Australia and England

Whilst peer observation of teaching is well established as a practice that can enhance teaching quality, the challenge to fully embed this practice in universities remains unresolved. This article analyses the perspectives of 18 university leaders (nine Australian and nine English) drawn from a range of school-based leaders to senior leaders of learning and teaching. Our study indicates that some of the challenges associated with leading such schemes can be mitigated through approaches to educational leadership that enact a respectful and collegiate ethos. This we suggest can support developmental academic engagement in peer observation for positive and lasting change.

Energy turnover during 24 hours and 6 days of adventure racing

Abstract

Energy turnover was assessed in two conditions of mixed ultra-endurance exercise. In Study 1, energy expenditure and intake were measured in nine males in a laboratory over 24 h. In Study 2, energy expenditure was assessed in six males during an 800-km Adventure race (mean race time 152.5 h). Individual correlations between heart rate and oxygen uptake ([Vdot]O₂) were established during pre-tests when kayaking, cycling, and running. During exercise, energy expenditure was estimated from continuous heart rate recordings. Heart rate and [Vdot]O₂ were measured regularly during fixed cycling work rates to correct energy expenditure for drift in oxygen pulse. Mean energy expenditure was 18,050 ± 2,390 kcal (750 ± 100 kcal · h^?1) and 80,000 ± 18,000 kcal (500 ± 100 kcal · h^?1) in Study 1 and Study 2 respectively, which is higher than previously reported. Energy intake in Study 1 was 8,450 ± 1,160 kcal, resulting in an energy deficit of 9,590 ± 770 kcal. Body mass decreased in Study 1 (?2.3 ± 0.8 kg) but was unchanged in Study 2. Fat mass decreased in Study 2 (?2.3 ± 1.5 kg). In Study 1, muscle glycogen content decreased by only 60%. Adventure racing requires a high energy expenditure, with large inter-individual variation. A large energy deficit is caused by inadequate energy intake, possibly due to suppressed appetite and gastrointestinal problems. The oxygen pulse, comparing start to 12 h of exercise and beyond, increased by 10% and 5% in Study 1 and Study 2 respectively. Hence, estimations of energy expenditure from heart rate recordings should be corrected according to this drift.
