The implementation of inclusion in schools currently requires new reflections of competence profiles of the teachers involved. Especially in elementary school, which can so far be considered as the most developed institution of inclusive schooling in Germany, questions of differences in the profiles of elementary and special education teachers have been raised. As professional skills also have motivational and volitional aspects, a beliefs model (domain overlapping) was developed based on the construction of the TEDS-M research project, which aims to study specific special educational beliefs. Using a quantitative questionnaire designed in the context of a corresponding preliminary investigation a three-factor-solution for mapping a special supportive belief profile among student teachers and teachers in the field of elementary and special education was tested. Initially this profile model was confirmed by the results of a subsequent analysis based on a nationwide sample of elementary school and special education students (N = 951). In addition to these findings different manifestations of the beliefs model could be identified among student teachers for elementary schools and student teachers for special education.  相似文献

In recent years, socio-technical transitions literature has gained importance in addressing long-term, transformative change in various industries. In order to account for the inertia and path-dependency experienced in these sectors, the concept of the socio-technical regime has been formulated. Socio-technical regimes denote the paradigmatic core of a sector, which results from the co-evolution of institutions and technologies over time. Despite its widespread acceptance, the regime concept has repeatedly been criticized for lacking a clear operationalization. As a consequence, empirical applications tend to depict regimes as too ‘monolithic’ and ‘homogenous’, not adequately considering persistent institutional tensions and contradictions. These are however crucial for assessing transition dynamics. In this paper, we revisit two concepts from institutional theory that enable an explicit identification of socio-technical regimes and more generally a specification of the ‘semi-coherence’ of socio-technical systems. First, we will show that ‘levels of structuration’ can be conceptualized as degrees of institutionalization, thereby treating institutionalization as a variable with different effects on actors, the stability of the system and thus the potential for change. Secondly, we draw on the institutional logics approach to characterize the content of various structural elements present in a system and to trace conflicts and contradictions between them. We illustrate this approach with an empirical in-depth analysis of the transformation of the Australian urban water sector since the 1970ies.  相似文献

There is increasing expectation that schools should be able to use tablets for a range of instructional and assessment purposes. This article considers the comparability of student writing on tablets and laptops to ensure that writing assessment is conducted in a way that is fair to all students. Data were collected from a sample of 826 students from Virginia and South Dakota at 2 grade levels. Each student was provided with a laptop, a tablet, or a tablet with an external keyboard and asked to respond to a grade-level-appropriate essay prompt. Results indicated no difference in the essay score or surface-level essay features across study conditions. However, the relatively short length of essays written, the fact that reference materials were not required to respond to the essay prompts, and the general motivational level of student participants were likely contributing factors to the observed outcomes.  相似文献

ABSTRACT

This study is one of the first to compare journalistic role performances of English– and Spanish–language TV networks during the 2016 U.S. primaries. Previous research finds that the corporate structure of Spanish–language media in the United States is looking more like its English–language counterparts and that Latino journalists share the norm of objectivity. Meanwhile, research suggests that individuals of different ethnicities turn to different communication channels and that this divergence can be explained by the degree of alignment in linguistic and cultural orientation. In this study, we therefore assess how linguistic differences of TV networks impact journalistic culture during the presidential primaries in 2016. As a crucial component of journalistic culture, we focus on journalistic role performance and find important distinctions: Findings reveal that the greater coverage of presidential candidates as sources on English-language networks have significant consequences for the roles journalists perform. Results suggest that the Spanish–language networks performed significantly more civic journalism roles than their English–language counterparts that perform an interventionist and service role. These differences are discussed alongside different audience-orientation of the networks that reflect deep racial and ethnic divides.  相似文献

Virtual worlds for adults (e.g. Second Life), youth (e.g. Habbo) and children (e.g. Whyville) have a great potential for learning and teaching practices for enriching wider public and engendering collective experience and collaboration. Informal learning environments such as virtual worlds offer children and adults various intellectual and sensory activities or flow experiences according to Csikszentmihalyi. Virtual worlds promote social interaction and offer visitors an opportunity for various interactive activities which can sometimes not be realized in real life education. Children and adults can explore and learn in a different way and from a different perspective, also with educational games. The paper deals with learning possibilities and opportunities in educational virtual worlds. Virtual worlds can introduce quality learning environment and offer new challenges in the educational field.  相似文献

Robust performance of a flight control system in the presence of parametric uncertainty and external disturbances is of paramount importance to a successful planetary exploration program. The present research is concerned with the design of an autopilot that uses high-order sliding mode (HOSM) control principles so as to enhance the robustness properties of a lunar landing vehicle during the approach phase of powered descent. The design technique is applied to a high-fidelity simulation of the Apollo Lunar Module (LM). The design efficiently utilizes both the reaction control system (RCS) actuators and the severely rate-limited gimbal drive actuator (GDA) to effect smooth detection and compensation of sensed angular acceleration disturbances about the vehicle's control axes. The integration of a HOSM control law for the RCS effectors with a HOSM disturbance observer is shown to provide performance comparable to that of the heritage autopilot and may also avoid some difficulties encountered in the Apollo flights. Performance is maintained with the controller implemented in discrete time in the presence of a realistic vehicle and sensor model, demonstrating a unique application of sliding mode control to a complex aerospace system.  相似文献

The Performance Assessment for Leaders (PAL) is a four-task evaluation system designed to improve the quality of initial school leaders in Massachusetts by evaluating candidate readiness using a rigorous, standard assessment system. By design, it is signalling leadership quality expectations to preparation programmes. Through two years of survey research with leadership preparation faculty (n?=?12) and candidates (n?=?53) who completed PAL, we explored faculty understanding the PAL assessment, assessment alignment task to programme content, candidate preparedness, and impact on programmes. Results show that faculty used PAL to improve their preparation programmes and provide high-quality learning experiences for candidates.  相似文献

Currently, it is unclear whether manipulation of movement velocity during resistance exercise has an effect on hypertrophy of specific muscles. The purpose of this systematic review of literature was to investigate the effect of movement velocity during resistance training on muscle hypertrophy. Five electronic databases were searched using terms related to movement velocity and resistance training. Inclusion criteria were randomised and non-randomised comparative studies; published in English; included healthy adults; used dynamic resistance exercise interventions directly comparing fast training to slower movement velocity training; matched in prescribed intensity and volume; duration ≥4 weeks; and measured muscle hypertrophy. A total of six studies were included involving 119 untrained participants. Hypertrophy of the quadriceps was examined in five studies and of the biceps brachii in two studies. Three studies found significantly greater increases in hypertrophy of the quadriceps for moderate-slow compared to fast training. For the remaining studies examining the quadriceps, significant within-group increase in hypertrophy was found for only moderate-slow training in one study and for only fast training in the other study. The two studies that examined hypertrophy of the biceps brachii found greater increases for fast compared to moderate-slow training. Caution is required when interpreting the findings from this review due to the low number of studies, hence insufficient data. Future longitudinal randomised controlled studies in cohorts of healthy adults are required to confirm and extend our findings.  相似文献

This study examines the complex process of change among teacher educators who have chosen to improve their practice in a professional development community. Storyline methodology was used to reveal the dynamic process which teacher educators undergo when they consider adopting innovative pedagogy. Findings reveal critical moments in professional development which are characterised by evaluation of feedback from colleagues and students. Professional growth results not only from interaction and negotiation of meaning within the community but also from the effects of messages received from outside the communal context. A two factor model taking into account implementation and feedback is used to show the dynamic process of evaluation and negotiation in teacher educators’ professional development trajectory. This study deepens understanding of transition towards change within learning communities, while providing insight into the development of teacher educators as a distinct professional group.  相似文献

The language barrier is a factor in the low visibility and significance of scientific journals produced by small and scientifically peripheral countries. In order to reach an international audience, both as consumers and producers of scientific information, many journals abandon their national language and start publishing in English. Six Croatian biomedical journals that went through this transition were examined on their editing and publishing characteristics and their international visibility before and after the language shift. The analysis showed that this change influenced the journals' characteristics in general. Two journals enhanced their international visibility, but only one journal showed improvement in all analysed indicators.  相似文献
