Quantum mechanics and classical computing

Scaling properties of modular quantum systems will dominate the future of quantum computing as well as the potential role of quantum mechanics in classical computing. We undertake a brief journey through length- and time-scales in order to locate pertinent control schemes. It is argued that ‘‘quantum benefits’’ are more likely to survive in ‘‘imbodied’’ systems like coherently driven materials, sensors or robots than in abstract digital computation.     

School leadership and intercultural understanding: school foyers as situated spaces for doing diversity

Internationally, Intercultural Understanding (ICU) is increasingly prevalent in the field of education. The recent evidence base includes a growing academic literature and examples of specified education policy and curricula. In regards to leveraging ICU, research suggests a multi-level and longitudinal approach is needed to ensure effective and sustainable school change. Significant gaps exist in the literature about the contextual factors across all school levels that facilitate or impede the development of ICU. These gaps include research and action pertaining to school leadership. This paper draws from interviews and visual data generated in a large Australian study and focuses on the centrality of a single architectural feature of the school, the school foyer, and how principals grapple with the (re)design of these spaces to assert themselves as interculturally capable schools. Discourses of educational leadership have historically relied on well-worn leadership models of operational practices rather than explicitly framing an understanding of diversity to support intercultural capabilities. During a period of mandated Australian curriculum reform and assessment, this paper offers another way of ‘Doing Diversity’ of interest to policy makers and school leadership keen to embed ICU in their schools while highlighting the significant role school leaders have in progressing ICU.     

Classroom Animals Provide More Than Just Science Education

Keeping classroom animals is a common practice in many classrooms. Their value for learning is often seen narrowly as the potential to involve children in learning biological science. They also provide opportunities for increased empathy, as well as socio-emotional development. Realization of their potential for enhancing primary children’s learning can be affected by many factors. This paper focuses on teachers’ perceptions of classroom animals, drawing on accounts and reflections provided by 19 participants located in an Australian primary school where each classroom kept an animal. This study aims to progress the conversation about classroom animals, the learning opportunities that they afford, and the issues they present. Phenomenographic analysis of data resulted in five categories of teachers’ perceptions of the affordances and constraints of keeping classroom animals.     

The Development of Professional Learning Communities and Their Teacher Leaders: An Activity Systems Analysis

Professional learning communities can be effective vehicles for teacher learning and instructional improvement, partly because they help change professional culture. However, little is known about how these changes occur. We used activity systems analysis to investigate the development of professional learning communities and their teacher leaders (N = 9) based on interviews and observations over 2 years. Activity systems analysis enables researchers to understand change within complex qualitative data sets by finding systemic relations within the activity, specifying contradictions in the system, and explicating outcomes. The resulting activity system illuminates the transformation of a mostly private, autonomous, and egalitarian culture to one of nascent collaboration, reflection, and shared values, as well as teacher leaders’ development of agency.

Short and long term effects of a teacher-training workshop in medical school

The effect of a teacher-training workshop in a medical school was studied. The change in instructional behavior was judged by the amount and kind of students' verbal activities during regular lessons and by the cognitive level of the teacher-student encounters. One hundred and sixty-one lessons of 60 teachers were observed in a period up to 500 days after the four-day workshop. The results indicate a considerable increase in both parameters following the training. The new level of performance was sustained for the activity parameter along the entire follow-up period. The cognitive level moderately declined after about 200 days. After 500 days the instructional behavior still was significantly different from that before the workshop. The implications for teacher-training and reinforcement interventions are discussed.     

Disability,curriculum and integration in China

ABSTRACT

Current data indicate that there are six million young people of school age with disabilities in China. Of these, only about 50 per cent attend any form of schooling, with approximately 220,000 of them enrolled in special schools and classes. The remainder attend regular classrooms. This means that there are about three million students with disabilities who at present lack any access to education. In May 1996 it was declared that in order to improve this situation, over the next five years, China plans to provide school places for 80 per cent of its disabled youngsters. In order to achieve this goal, the Chinese central education authorities have announced a significant change in policy direction towards integration. Instead of their previous commitment to the establishment of increasing numbers of special schools, it is now planned that the current number of about 1,400 special schools will be increased to 2,000, so that all regions of the country have access to at least one. At that point, no more special schools will be built. The extra places needed to increase the school attendance rate of youngsters with disabilities will be created in regular classes in regular schools. This paper gives an overview of the curriculum arrangements in China's four types of special schools, including their historical development, subjects taught, teaching arrangements and management. A number of difficulties confronting China's special education policy‐makers are canvassed and reasons suggested for their increasing commitment to a strategy of integration. It is proposed that China enjoys three advantages in the pursuit of an integrated school system.     

Content-Related Knowledge of Biology Teachers from Secondary Schools: Structure and learning opportunities

Teachers’ content-related knowledge is a key factor influencing the learning progress of students. Different models of content-related knowledge have been proposed by educational researchers; most of them take into account three categories: content knowledge, pedagogical content knowledge, and curricular knowledge. As there is no consensus about the empirical separability (i.e. empirical structure) of content-related knowledge yet, a total of 134 biology teachers from secondary schools completed three tests which were to capture each of the three categories of content-related knowledge. The empirical structure of content-related knowledge was analyzed by Rasch analysis, which suggests content-related knowledge to be composed of (1) content knowledge, (2) pedagogical content knowledge, and (3) curricular knowledge. Pedagogical content knowledge and curricular knowledge are highly related (r_latent?=?.70). The latent correlations between content knowledge and pedagogical content knowledge (r_latent?=?.48)—and curricular knowledge, respectively (r_latent?=?.35)—are moderate to low (all ps?<?.001). Beyond the empirical structure of content-related knowledge, different learning opportunities for teachers were investigated with regard to their relationship to content knowledge, pedagogical content knowledge, and curricular knowledge acquisition. Our results show that an in-depth training in teacher education, professional development, and teacher self-study are positively related to particular categories of content-related knowledge. Furthermore, our results indicate that teaching experience is negatively related to curricular knowledge, compared to no significant relationship with content knowledge and pedagogical content knowledge.     

Quantification of wall surface heterogeneity and its influence on species diversity at medieval castles – implications for the environmentally friendly preservation of cultural heritage

Historic buildings are important for cultural history and provide a variety of habitats for animals and plants. Especially structural heterogeneity of wall surfaces is perceived to support biological diversity. Nevertheless, in traditional approaches goals of biodiversity preservation and monument restoration are perceived to interfere and to be mutually exclusive. As a consequence, priority is often given to constructional restoration accepting the loss of local populations and biodiversity. At walls of medieval castles, including an experimental restoration project where conventional and less intensive restoration techniques were applied, we relate species composition and richness to wall properties. Especially wall surface structure is quantified using a novel approach. The study focuses on lichens, mosses and vascular plants. Boosted regression tree analyses and non-metric multidimensional scaling techniques are applied to detect the influence of abiotic site conditions on biodiversity. We find species richness to be promoted by wall surface heterogeneity. However, species composition is more affected by restoration approaches than species richness. Lichen composition varies considerably while vascular plants and mosses are less affected by wall properties. We suggest strategies that are combining both societal targets, the preservation of historic monuments and of species diversity. Careful restoration is capable of supporting both, the maintenance of cultural heritage and of rare and unique anthropogenic habitats. Wall surface heterogeneity needs to be witnessed for both aspects as it affects both species composition as well as the effectiveness of cleaning methods.
