The use of technology to facilitate education and the provision of an entire higher education degree has exploded in the last two decades. Social work educators have been a part of that trend and have started to utilize distance education (DE) technologies. There is a growing literature regarding the efficacy of DE instruction in social work, and scholars are actively developing best practices. However, there is little research in general to support the cost of DE, no cost studies in social work, and none comparing costs of DE delivery to costs associated with a face-to-face program. This study hopes to fill this gap by providing an analysis of the direct costs of an MSW DE program in comparison to similar costs of a face-to-face program. 相似文献

The diverse student population at large multi-campus universities requires English language and academic skills support which is targeted to their needs and easily accessible. The Online Student Resource Centre website, developed at Monash University, provides opportunities for students, no matter where they are, to make contact with staff and to access information, but more significantly offers a suite of stand-alone tutorials and downloadable resources, using NetObjects Fusion as the platform. These derive from some 100 print booklets covering academic writing, reading, listening, speaking, grammar and study skills/exam strategies. This paper outlines the process and philosophy of development of these tutorials, based on a constructivist framework, with guided and self-directed learning paths designed to accommodate a range of learning styles. Two tutorials are analysed to highlight some of the pedagogical challenges in translating print resources for the online environment. The paper concludes by reporting on a pilot evaluation of the two tutorials. Transformation d’un support d’enseignement: un centre de ressources en ligne pour une population variée d’étudiants. Les populations trés variées d’étudiants dans les grand campus multiples de certaines universités exigent une langue anglaise et des compétences académiques adaptés À leurs besoins et facilement accessible. Le centre de ressources en ligne pour les étudiants grÂce au site web, mis au point À Monash University fournit aux étudiants, où qu’ils soient, des occasions de contacts avec les enseignants et d’accès À l’information, mais de facon plus significative, offre une série d’actions de tuteurs alors que les étudiants sont seuls et de ressources que l’on peut télécharger utilisant la fusion d’objet du Net comme platforme. Ceux ci sont extraits d’une centaine de livrets imprimés concernant l’écriture, la lecture, l’écoute, la parole, la grammaire et les compétences pour les études et les stratégies des examens. L’article donne les grandes lignes et la philosophie du développement de ces exercices de tutorat, basés sur un cadre constructiviste comportant des cheminements d’apprentissage guidés et dirigés par les étudiants pour faire face À toute une série de styles d’apprentissages. On analyse 2 exercices de tutorat pour mettre en valeur certaines challenges pédagogiques en traduisant des ressources imprimés pour un environnement on ligne. L’article se termine par le rapport d’une évaluation pilote de ces 2 exercices. Veränderte Lernhilfen: Ein Online Resource Centre für unterschiedliche Studentengruppen. Unterschiedliche Studentengruppen an grossen Campus Universitäten benötigen Unterstützung in der englischen Sprache und bei der Verbesserung der akademischen Fähigkeiten, die auf ihre Bedürfnisse zugeschnitten und einfach zugänglich ist. Das Online Student Resource Centre, das auf der Webseite von der Monash Universität entwickelt wurde, bietet den Studenten Gelegenheit, unabhängig von ihrem Wohnort, sich mit den Lehrern in Verbindung zu setzen und Informationen abzurufen, aber darüber hinaus bietet es ein Forum für Tutorials and kopierfähiges Informationsmaterial unter Anwendung von NetObjects Fusion als Plattform. Dieses Unterstützungsmaterial stammt von 100 gedruckten Büchern über die Disziplinen, wissenschaftliches Schreiben, Lesen, Hören, Sprechen, Grammatik und Lernfähigkeiten /Prüfungsstrategien. Dieser Artikel beschreibt den Prozess und die Philosophie, die der Entwicklung dieser Tutorials zugrunde liegen und auf einem ausbaufähigen System basieren und mit vorgegebenen und selbst bestimmten Lernpfaden so angelegt sind, dass sie mehrere Lernstile berücksichtigen. Zwei Tutorials werden analysiert um an ihnen einige der pädagogischen Herausforderungen zu verdeutlichen, die bei der übertragung von gedrucktem Material in das online Lernfeld entstehen. Der Artikel endet mit einem Bericht über die Pilot Evaluierung dieser beiden Tutorials. 相似文献

AbstractAssessment for learning (AfL) practices are commonly recommended as effective classroom strategies for providing teachers with information about student understanding. For teachers, the substantive potential of these AfL practices to inform student learning actions depends on what teachers notice and select as a focus and how they interpret and act on the information they have. This paper suggests research on teacher professional noticing has something to offer in understanding how teacher AfL attention and actions are framed in the moment. It explains noticing as a responsive act that invites action that is an inclusive, dynamic and purposeful response to evidence of student ideas. Noticing is what enables a teacher to act on the fly because it informs and underpins possible actions. Three frames of noticing are introduced to guide noticing and action – curriculum connoisseurship, cultural and community connectedness, and collaborative ways of working. Through consideration of classroom events using these frames, teachers become better prepared to choose to respond in the moment creatively. The three frames provide teachers and researchers with a conceptual language to articulate and sharpen their AfL practices as part of a flexible and rigorous responsiveness to their students’ learning. 相似文献

Generalisation is inescapable. We all generalise. It is part of our cognitive apparatus and it is fundamental to the way we live. Our understanding of the world has to go beyond our own unique and limited experiences if we are to interact, empathise, understand and communicate with others in our social milieu. Without generalisation we could not interact with our world in a meaningful and coherent way – that is to say, we would need continual repetition of the same mental procedures for each new experience. 相似文献

Recently the definition of motor development seems to have engendered a debate among a number of scholars in the field. We suggest that the controversy stems from confusion about whether motor development is a product or a process. When motor development is defined as change over time in motor behavior, the focus is on motor performance (i.e., product), whereas when motor development is defined as a process, the emphasis is on the underlying mechanisms of change. Clearly, the proper definition of motor development includes both the product and process of change. Through an historical overview of the field, we trace the origins of this definitional confusion and its impact on the study of motor development. The paper concludes with our position as to the future directions for motor development research. 相似文献

In this paper, we focus on an initiative in England devised to prepare non-mathematics graduates to train as secondary mathematics teachers through a 6-month Mathematics Enhancement Course (MEC) to boost their subject knowledge. The course documentation focuses on the need to develop “understanding mathematics in-depth” in students in order for them to become successful mathematics teachers. We take a poststructural approach, so we are not interested in asking what such an understanding is, about the value of this approach or about the effectiveness of the MECs in developing this understanding in their participants. Instead we explore what positions this discourse of “understanding mathematics in-depth” makes available to MEC students. We do this by looking in detail at the “identity work” of two students, analysing how they use and are used by this discourse to position themselves as future mathematics teachers. In doing so, we show how even benign-looking social practices such as “understanding mathematics in-depth” are implicated in practices of inclusion and exclusion. We show this through detailed readings of interviews with two participants, one of whom fits with the dominant discourses in the MEC and the other who, despite passing the MEC, experiences tensions between her national identity work and MEC discourses. We argue that it is vital to explore “identity work” within teacher education contexts to ensure that becoming a successful mathematics teacher is equally available to all. 相似文献

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. 相似文献

ABSTRACTPurpose: 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. 相似文献

In reviews of university teacher training, the parts of the curriculum based on educational science are often criticized as missing practical relevance and being non-cumulative. At the same time, uncertainty exists regarding which educational science based content is important for teacher candidates. The objective of the Delphi study presented here was the identification of core educational science content in university training. To this aim, a survey was carried out amongst 49 experts from different subject areas and phases of teacher training in three rounds using a standardized questionnaire. In the first round, 213 topics were specified, which were then assessed by experts regarding their importance for various aspects of the teaching profession. In the second and third rounds, which had the objective of reducing the number of topics, the experts chose a limited number of topics based on their relevance for university teacher training and for the practical success of teaching itself. The results show that the original list was comprehensive and that there is a consensus among most of the experts on their respective importance for teaching training. 相似文献
