As institutions of Higher Education try to balance limited resources with the rising costs of technology, some institutions are turning to Open Source software for campus-wide applications such as course management systems and portals. The assumption is that Open Source will provide the flexibility to build pedagogically sound learning environments while increasing technology efficiencies. This paper outlines the current state of Open Source software deployment in US Higher Education based on a survey of 772 Chief Academic Officers and Chief Information Officers conducted in 2006. The results indicate that Carnegie classification is a critical differentiator of awareness, adoption, and perceptions of Open Source software applications, with perceived cost of ownership being the key driver of Open Source adoption. Moreover, the study shows that institutions have made little progress in the development of polices and procedures for Open Source regulatory compliance and security. The study serves as a baseline for future research into the conditions for successful use of Open Source for supporting integrated learning environments that deliver campus-wide efficiencies.

Theory-of-mind (ToM) abilities were studied in 176 deaf children aged 3 years 11 months to 8 years 3 months who use either American Sign Language (ASL) or oral English, with hearing parents or deaf parents. A battery of tasks tapping understanding of false belief and knowledge state and language skills, ASL or English, was given to each child. There was a significant delay on ToM tasks in deaf children of hearing parents, who typically demonstrate language delays, regardless of whether they used spoken English or ASL. In contrast, deaf children from deaf families performed identically to same-aged hearing controls (N=42). Both vocabulary and understanding syntactic complements were significant independent predictors of success on verbal and low-verbal ToM tasks.  相似文献

Age differences in decision making indicate that children fail to anticipate outcomes of their decisions. Using heart rate and skin conductance analyses, we tested whether developmental changes in decision making are associated with (a) a failure to process outcomes of decisions, or (b) a failure to anticipate future outcomes of decisions. Children aged 8-10, 12-14, and 16-18 years performed the Hungry Donkey task, a child version of the Iowa Gambling Task, while heart rate and skin conductance activity were continuously recorded. Children aged 16-18 learned to make advantageous choices over task blocks faster than the two younger age groups. Age differences were present for anticipation-related autonomic activity but not outcome-related autonomic activity. The results are interpreted vis-à-vis models of prefrontal cortex maturation.  相似文献

The Linguistic European Policy stresses the importance of linguistic diversity and encourages students to learn several languages, believing that the more languages we know, the better we can understand each other and preserve our languages. To preserve diversity and to value all the languages (either included in the curriculum or not) is a first step to develop a plurilingual and intercultural competence in the classroom as a means of overcoming frontiers between languages and between people. A second step is to work with teachers and to value what they know by helping them to find new and innovative answers to meet these professional challenges. Thus, this paper describes the work within a project for professional development of a group of in‐service language teachers. The teacher education programme suggests a portfolio‐oriented language learning and teaching approach that promotes plurilingualism. We will analyse the teachers' starting point and their willingness to work within an innovative and challenging approach. The analysed data include a questionnaire prior to the starting of the programme and three written reflections at the end of the programme concerning professional development, new concepts, teaching approach and working habits. The conclusions indicate that the teachers were not familiar with either the concept of plurilingualism or the portfolio‐oriented language learning and teaching approach. Nevertheless, they clearly show their willingness to try a new approach in their teaching practice.

La politique linguistique européenne défend l'importance de la diversité linguistique et encourage l'apprentissage de diverses langues, en croyant que la maîtrise de plusieurs langues augmente la capacité de comprendre les autres et de préserver nos propres langues. Préserver et valoriser toutes les langues (présentes, ou pas, dans le curriculum scolaire) est le début du développement de la compétence plurilingue et interculturelle. Ceci constitue un moyen de dépasser les barrières entre des langues et des peuples différents. Un deuxième pas est le travail avec les enseignants, en valorisant leurs connaissances et en les aidant à découvrir de nouvelles réponses, capables de faire face aux défis de la gestion de la diversité. Cet article décrit le travail mené au sein d'un programme de formation continue destiné à un groupe d'enseignants de langues. Ce programme de formation se construit autour d'une approche plurilingue où le portfolio est le concept‐clé. Le texte présente l'analyse du point de départ des enseignants, en explicitant leurs prédispositions à travailler d'une autre façon. Les données analysées incluent les réponses à un questionnaire antérieur au programme de formation et trois réflexions écrites à la fin de ce même programme à propos du développement professionnel (nouveaux concepts, nouvelle approche, nouvelles habitudes). Les résultats montrent que les enseignants n'étaient familiarisés ni avec le concept de plurilinguisme ni avec l'utilisation du portfolio. Toutefois, les enseignants révèlent le désir d'essayer une nouvelle approche dans leurs pratiques d'enseignement.

La política lingüística europea defiende la importancia de la diversidad lingüística y alienta a aprender varios idiomas, en la convicción de que cuantos más idiomas sabemos, mejor podemos entendernos y preservar nuestros idiomas. Preservar y valorar todas las lenguas (estén o no presentes en el currículum) es un primer paso para desarrollar una capacidad plurilingüe e intercultural en clase, que se convierte en un medio de superar las barreras entre idiomas y entre pueblos. Un segundo paso es trabajar con profesores, valorando lo que saben y ayudándolos a descubrir nuevas e innovadoras respuestas para su desarrollo profesional en momentos de cambios. Este escrito describe el trabajo llevado a cabo en el marco de un proyecto para el desarrollo profesional de un grupo de profesores en un instituto, a partir de un programa de formación sobre enseñanza y aprendizaje de idiomas basado en el porfolio. Analizaremos el punto de partida de su camino y la predisposición para trabajar un abordaje innovador y desafiante del currículum. Los datos analizados incluyen las respuestas a un cuestionario anterior al programa de formación y tres reflexiones escritas en el término de ese programa, sobre desarrollo profesional, nuevos conceptos y hábitos de trabajo. Las conclusiones indican que los profesores no estaban familiarizados ni con el concepto de plurilingüismo ni con la enseñanza y aprentisage de idiomas basado en el porfolio. Sin embargo, evidencian predisposición para intentar nuevos abordajes en sus practicas profesionales.

Die Europäische Sprachenpolitik legt grossen Wert auf die linguistische Vielfalt. Eine der Prioritäten ist demnach, Schüler zum Erlernen mehrerer Fremdsprachen zu motivieren. Diese Idee basiert auf der Grundlage, dass das Erlernen mehrerer Sprachen nicht nur eine bessere Verständigung zwischen Kulturen ermöglicht, sondern auch die eigene Sprache und Kultur erhält. Die linguistische Vielfalt zu erhalten und grossen Wert auf alle Sprachen zu legen (im Lehrplan beinhaltet oder nicht) stellt einen ersten Schritt dar, eine mehrsprachige und interkulturelle Kompetenz im Klassenzimmer zu entwickeln, zur Überwindung von Grenzen zwischen Sprachen und Leuten. Ein zweiter Schritt ist die Arbeit mit Lehrern, in der deren Vorkenntnisse wichtig genommen werden und ihnen damit geholfen werden soll, neue Antworten für die entsprechenden beruflichen Herausforderungen auszuarbeiten. In diesem Vortrag soll die Zusammenarbeit mit einer Lehrergruppe im Rahmen einer beruflichen Weiterbildung beschrieben werden. Das Lehrerausbildungsprogramm schlägt ein portfolio‐orientiertes Sprachlernen und Unterrichten vor, das Sprachenvielfalt fördert. Es soll analysiert werden, aus welchen Ausgangspunkten die Lehrer kommen und welche Bereitschaft sie zu einer innovativen Unterrichtspraxis zeigen. Die analysierten Daten, ein Fragebogen vor Programmbeginn und drei schriftliche Reflexionen am Ende des Programms, beziehen sich auf professionelle Entwicklung neuer Konzepte, Unterrichtspraxis und Arbeitsmitte. Die Schluβfolgerungen zeigen, dass die Lehrer weder mit dem Konzept der Mehrsprachigkeit noch mit dem portfolio‐orientierten Sprachlernen und Unterrichten vertraut waren. Andererseits deuten sie auf eine Bereitwilligkeit von Seiten der Lehrer, eine neue Herangehensweise ihre Unterrichtspraxis zu erproben.  相似文献

Peer and near-peer teaching programs are common in medical undergraduate courses. However, there are no studies that have investigated the effectiveness of a near-peer teaching program on the academic performance of undergraduate students pursuing sport and exercise science coursework. This study was conducted to analyze the effectiveness of such a program for students who participated in a course on the functional anatomy of the locomotor apparatus. A total of 39 student participants were divided into two groups: students in one group voluntarily attended at least one session of a near-peer teaching program, and students in the other group attended no sessions. The final grade (range 0–100%) was recorded and used as an indicator of academic performance. The final grade of students who attended the near-peer teaching program (69.5 ± 16.0%) was 38.7% higher (P = 0.002, d = 1.06) than those who did not (50.1 ± 20.4%). When the academic performance of the same students was evaluated in another course (exercise physiology) that did not offer a near-peer teaching program, there were no significant differences between the groups (students who attended or did not attend the near-peer teaching program). A significant positive association was found between near-peer teaching program frequency and the number of students approved and not approved in the course (P = 0.041). A significant difference (P = 0.001) was found in the attendance at regular classes between the group who participated in the near-peer teaching program (median: 62 hours; IQR [interquartile ranges]: 4.0 hours) and those who did not (median: 58 hours; IQR: 4.0 hours). Gender was not a moderating factor on academic performance or near-peer teaching program attendance. These results highlight the effectiveness of a near-peer teaching program on the academic performance of students from a sport and exercise science degree program while enrolled in an anatomy course.

The number of students studying for university qualifications through the medium of English and for whom English is not their first language has increased significantly in recent years. This, along with efforts to widen access to those under-represented in higher education, has brought into focus the question of what academics see as constituting a ‘good’ piece of student writing. In this small-scale pilot study, Thurstone’s method of paired comparisons was used to establish a scale for ranking six essays in terms of how favourably each was viewed by academic lecturers when compared with every other essay in the set. Kelly’s repertory grid technique was subsequently applied to interviews conducted with the same lecturers to establish which traits they associated with the upper and lower end of the scale. Findings suggest that this methodology represents a promising approach to establishing what academic tutors regard as the key elements of good writing and thus provides an indication of what English teachers might fruitfully focus on in their teaching of the skill.  相似文献

This study aimed to investigate if moderate to vigorous physical activity (MVPA) and aerobic fitness are associated with cardiovascular risk factors in HIV+ children and adolescents. Sixty-five children and adolescents (8 to 15 years) provided minutes of MVPA measured by accelerometers and peak oxygen uptake (peak VO2) by breath-by-breath respiratory exchange. Cardiovascular risk factors were characterized by body fat, blood pressure, total cholesterol, HDL-c, LDL-c, triglycerides, glucose, insulin, C-reactive protein (CRP), interleukin (IL)-6, tumor necrosis factor-alpha (TNF-α) and carotid intima-media thickness. Results indicated that higher MVPA was associated with lower values of total (β = ?3.566) and trunk body fat (β = ?3.495), total cholesterol (β = ?0.112) and LDL-c (β = ?0.830). Likewise, higher peak VO2 was associated with lower total (β = ?0.629) and trunk body fat values (β = ?0.592) and levels of CRP (β = ?0.059). The physically active participants had lower total cholesterol (?24.4 mg.dL?1) and LDL-c (?20.1 mg.dL?1) compared to participants judged to be insufficiently active. Moreover, participants with satisfactory peak VO? showed lower total (?4.1%) and trunk (?4.3%) body fat, CRP (?2.3 mg.L?1), IL-6 (?2.4 pg.mL?1) and TNF-α (?1.0 pg.mL?1) compared to low peak VO2 peers. High levels of MVPA and aerobic fitness may prevent developing of cardiovascular risk factors in children and adolescents HIV+.  相似文献
