Classroom to Communities of Practice: Benefits for English Learners and Teacher Candidates Through Partnerships     

Michele Regalla  Alex Davies  Donita Grissom  Antonio Losavio 《Multicultural Perspectives》2018,20(1):25-32

This study investigates a service-learning program for university students seeking teacher certification examined through the lens of sociocultural theory. Data was collected from teacher candidates (TCs) in the form of surveys and an open-ended writing assignment. Administrators from the partner schools were also interviewed to provide their perspectives of the service learning. Findings show that the service-learning program allowed TCs and their English learners (ELs) to form communities of practice that were mutually beneficial. Teacher candidates reported numerous opportunities to apply the strategies learned in their methods course, as well as an increase in their sense of preparation for teaching ELs. Administrators provided positive feedback about the service-learning program in terms of the relationship between the partner school and the university. Difficulties arose in terms of TCs' accountability and the level of participation afforded to the TCs by the classroom teacher. Implications highlight the importance of negotiating expectations that address the needs of both parties equally in order to support a strong community of practice that prepares TCs to meet the needs of ELs.  相似文献   

A comparison of role concepts between public and parochial school teachers     

Norman J. Presse  Robert E. Bills 《Psychology in the schools》1981,18(1):107-111

This study seeks to determine if the same five bipolar factors that appear for the ideal role concepts of public school teachers also appear for parochial school teachers. Subjects included 185 teachers from a Catholic diocese. The data were factor analyzed by means of a principal axis analysis with varimax rotation. An analysis of variance was used to compare the factor analyses. The results indicated that parochial and public school teachers have similar factor structures. When comparing factor scores of the two groups, there were significant differences on several factors, indicating that parochial school teachers adopt a more facilitating role than do public school teachers.  相似文献   

The “Other” in the Crusading Period: Walter the Chancellor's Presentation of Najm al-Dīn Il-Ghāzī     

Alex Mallett 《Al-Masaq: Islam & the Medieval Mediterranean》2010,22(2):113-128

This paper examines ideas surrounding the presentation of the Muslim “other” in Latin writings of the early period of the Crusades. Using a case-study approach of the views of one chronicler, Walter the Chancellor, in his work Bella Antiochena, on one individual Muslim, Najm al-Dīn Il-Ghāzī, the paper studies aspects of the image of Il-Ghāzī, the reasons for them, how and why they develop throughout the chronicle, and whether, from the other information given in the chronicle, it would be possible to interpret the information in other ways. The conclusions reached demonstrate that the reason for the vitriol in Walter's presentation was his wish to justify the Crusades and suggest that the writers of Outremer started to develop their own cross-cultural responses to Islam, independent of mainstream European thought, because of their situation.  相似文献   

Reciprocal Versus Nonreciprocal Assessment of Knee Flexors and Extensors in Concentric Actions Using the CON-TREX Multijoint Isokinetic Dynamometer: A Reliability Study     

Alex Bliss  Jeanne Dekerle 《Measurement in physical education and exercise science》2019,23(2):118-123

Knee flexor and extensor muscular assessment via isokinetic dynamometry is common practice and established in the research literature. However, reporting assessment methodology regarding reciprocal and nonreciprocal movements is often vague or absent. Such methodological issues are crucial for accurate assessments. Therefore, knee extensor and flexor peak moment using either reciprocal movement or nonreciprocal modalities was assessed. Fifteen participants performed three blocks of five concentric muscle actions at three angular velocities [1: nonreciprocal (maximal active flexion followed by passive extension); B2: reciprocal (maximal active extension followed by maximal active flexion); B3 nonreciprocal (maximal active extension followed by passive flexion)]. ANOVA revealed statistically significant within-subject modality effects for peak knee extensor moment and flexor velocity and modality differences (p < .05). Reciprocal and nonreciprocal assessments give significantly different results, with nonreciprocal giving higher peak moments. Reporting which modality is used is crucial to allow for greater clarity for the reader and practitioner.  相似文献   

Validating the Sedentary Sphere method in children: Does wrist or accelerometer brand matter?     

Liezel Hurter  Alex V. Rowlands  Stuart J. Fairclough  Karl C. Gibbon  Zoe R. Knowles  Lorna A. Porcellato 《Journal of sports sciences》2019,37(16):1910-1918

This study aimed to validate the Sedentary Sphere posture classification method from wrist-worn accelerometers in children. Twenty-seven 9–10-year-old children wore ActiGraph GT9X (AG) and GENEActiv (GA) accelerometers on both wrists, and activPAL on the thigh while completing prescribed activities: five sedentary activities, standing with a phone, walking (criterion for all 7: observation) and 10-min free-living play (criterion: activPAL). In an independent sample, 21 children wore AG and GA accelerometers on the non-dominant wrist and activPAL for two days of free-living. Per cent accuracy, pairwise 95% equivalence tests (±10% equivalence zone) and intra-class correlation coefficients (ICC) analyses were completed. Accuracy was similar, for prescribed activities irrespective of brand (non-dominant wrist: 77–78%; dominant wrist: 79%). Posture estimates were equivalent between wrists within brand (±6%, ICC > 0.81, lower 95% CI ≥ 0.75), between brands worn on the same wrist (±5%, ICC ≥ 0.84, lower 95% CI ≥ 0.80) and between brands worn on opposing wrists (±6%, ICC ≥ 0.78, lower 95% CI ≥ 0.72). Agreement with activPAL during free-living was 77%, but sedentary time was underestimated by 7% (GA) and 10% (AG). The Sedentary Sphere can be used to classify posture from wrist-worn AG and GA accelerometers for group-level estimates in children, but future work is needed to improve the algorithm for better individual-level results.  相似文献   

Stretching and Challenging the Boundaries of Law: Varieties of Knowledge in Biotechnologies Regulation     

Alex Faulkner  Lonneke Poort 《Minerva》2017,55(2):209-228

The paper addresses the question of adaptation of existing regulatory frameworks in the face of innovation in biotechnologies, and specifically the roles played in this by various expert knowledge practices. We identify two overlapping ideal types of adaptation: first, the stretching and maintenance of a pre-existing legal framework, and second, a breaking of existing classifications and establishment of a novel regime. We approach this issue by focusing on varieties of regulatory knowledge which, contributing to and parting of political legitimacy, in principle enable the making of legally binding decisions about risks and benefits of technologies. We base the discussion around two case studies, one of animal biotechnology ethical regulation, the other of ‘advanced therapy’ medicinal product regulation, both in the context of European Union frameworks. Specifically, we explore the knowledge configurations constituting expert committees and other institutional formations of expert regulatory knowledge in their political context. We show that where sectoral and moral boundaries are challenged, different modes of regulatory knowledge beyond scientific forms – legal, procedural, moral, economic and industrial – can shape regulatory innovations either by maintenance of regimes through commensuration and stretching, or through differentiation and separation creating new frameworks. We conclude that establishing an essential techno-scientific difference between pre-existing and novel technologies does not in itself require new regulatory structures, and that the regulatory strategy that is followed will be determined by a combination of different forms of knowledge.  相似文献   

Islamic Historians of the Ayyūbid Era and Muslim Rulers from the Early Crusading Period: A Study in the Use of History     

Alex Mallett 《Al-Masaq: Islam & the Medieval Mediterranean》2012,24(3):241-252

This article examines the presentation of Muslim rulers from the early crusading period, 490–540/1097–1146 in six of the main chronicles written during the first half of the seventh/thirteenth century. It discusses the themes, ideas and topoi in each, demonstrating that the historians appear to have been divided into two ‘camps’ over their presentation of these rulers, based on their personal views of the rulers of their time. The article also examines why this division may have occurred, and considers its ramifications for modern scholarship of Arabic historiography, Islamic history and the history of the Crusades, in both the sixth/twelfth and seventh/thirteenth centuries.  相似文献

Self-concept as a function of intelligence and creativity in gifted Israeli children     

Roberta M. Milgram  Norman A. Milgram 《Psychology in the schools》1976,13(1):91-96

The relationship of creativity and intelligence to self-concept was examined in Israeli children (N = 159) of superior intelligence (mean WISC IQ = 140) across a wide age range (Grades 4–8). The instruments were the Wallach & Kogan Creativity battery, a group intelligence test and the Tennessee Self-Concept Scale. It was concluded that for children of superior intelligence, differences in creativity level were far more implicated in personal-social adjustment than were differences in intelligence level.  相似文献
