Moving the field of Mind, Brain, and Education forward requires researchers and educators to reframe the boundaries of their own discipline in order to create knowledge that is both scientifically based, and of practical relevance for education. We believe that this could be done by co‐constructing research projects from the start. We present a case study of a noise‐reduction intervention in elementary classrooms, in which teachers and researchers worked together from the onset of study design. We examine the processes behind: (1) selecting research questions and measures, (2) planning interventions, (3) receiving ethical approval and funding, (4) recruiting schools, and (5) collecting data. At each step, our study provides suggestions for future collaborative efforts, keeping in mind broader theoretical and methodological implications. We believe that our concrete examples and suggestions will be useful for beginning and confirmed researchers, as well as teachers aiming to know more about research projects. 相似文献

This paper examines the processes involved in building instructional applications that are based in artificial intelligence (AI) and hypermedia (HM) technologies. It seeks to define an initial methodology to capture these processes in a systematic manner, thus laying the foundations for the emergence of an ISD-like technology of design in the field of intelligent tutoring and advanced technologies. The joint consideration of AI and HM technologies in this respect is deliberate, for even if each appears to favour somewhat different instructional strategies from the other (Duchastel, 1990; 1991), the two technologies are nevertheless merging into integrated knowledge-based systems within the scope of computer-hosted training (McAleese, 1991).This section was introduced in Volume 16, No. 2, for such purposes as: rapid publication of summaries of work in progress (normally in the issue following receipt); outlines of projects or research themes in particular institutions; short papers expressing a strongly-held view or highlighting gaps in the literature; and conventional letters to the editor. We reserve the right to reject submissions or to require changes before publication. 相似文献

Afforestation in China provides carbon sequestration and prevents soil erosion, but its remote impacts on climate in other regions via the coupling of forest energy fluxes with atmospheric circulation are largely unknown. Here, we prescribe inventory-based forest cover change and satellite-observed leaf area index from 1982 to 2011 in a coupled land-atmosphere model to simulate their biophysical climate effects. Both local and global surface air temperatures show a seasonal contrast in response to past vegetation cover expansion over China: a phenomenon we primarily attribute to a variation of seasonality of vegetation greening. A large cooling in spring results in concurrent decreases in geopotential height over China and zonal wind over Mongolia, causing a dipole structure in the upper troposphere over the Arctic. This accounts for ∼58% of simulated spring warming over the Russian Arctic and ∼61% of simulated spring cooling over the Canadian Artic. Our results imply that spring vegetation dynamics in China may affect climate in northern high latitudes. 相似文献

The debate about whether the arts should be supported or not is far from new, and most governments support the arts in one
way or the other. The literature considers several arguments in favor of such interventions. Public education may seem to
be an action which could, in the long run, lead to possible reductions of subsidies. Surveys show that those who have been
exposed to the arts when young participate more when adult. However, the “non-market” transmission from parents to children
generates an external effect, which has to be taken into account to reach first-best situations. We construct an overlapping
generations model in which young consumers are exposed to both public education toward the arts and to non-altruistic transmission
of such a taste from their parents. We show that the first-best can be reached only if there is both public cultural education
and subsidization of arts consumption. Therefore, education cannot be considered as a substitute for subsidies to arts consumption.
However, as is often the case in European countries, government intervention is usually below the first-best level. Using
a model calibrated on French data, we show that it is then preferable to subsidize education, while consumption, especially
of the older generations, should be taxed rather than subsidized.

Vitamin B12 deficiency can present with neurologic and psychiatric symptoms without macrocytic anaemia. We describe a case of late-onset cobalamin C deficiency which typically presents with normal serum vitamin B12 concentrations, posing an additional diagnostic challenge. A 23-year-old woman with decreased muscle strength and hallucinations was diagnosed with ‘catatonic depression’ and admitted to a residential mental health facility. She was referred to our hospital for further investigation 3 months later. Heteroanamnesis revealed that the symptoms had been evolving progressively over several months. Magnetic resonance imaging (MRI) of the brain showed diffuse symmetrical white matter lesions in both hemispheres. Routine laboratory tests including vitamin B12 and folic acid were normal except for a slight normocytic, normochromic anaemia. Over the next 6 weeks her symptoms deteriorated, and she became unresponsive to stimuli. A new MRI scan showed progression of the white matter lesions. The neurologist requested plasma homocysteine (Hcys) which was more than 8 times the upper limit of normal. Further testing revealed increased methylmalonic acid and the patient was diagnosed with adult-onset cobalamin C deficiency. This case illustrates that Hcys and/or methylmalonic acid should be determined in patients presenting with neuropsychiatric symptoms suggestive of vitamin B12 deficiency with a normal serum vitamin B12 to rule out a late-onset cobalamin C deficiency. 相似文献

This article investigates the implementation of the “förstelärare” or “First teacher” reform in Sweden. We draw upon the insights of a superintendent, union official, principal, three First teachers, and two of their colleagues in one school, and recent literature on career development reform. We employ Michael Fullan’s overview of the “right” and “wrong” drivers of educational reform to analyse the extent to which the First Teacher initiative cultivated productive “professional capital.” The research reveals: how broader national policy aims were in clear tension with municipal-wide school development, and school-level development efforts; the perverse effects of a strong focus upon salary on professional conduct; and how an emphasis upon teachers’ roles per se undermined the espoused policy focus on enhancing teaching. The research cautions against the problematic effects of the initiative on more profession-oriented prerogatives, and how more external, “deleterious,” drivers of reform militate against more productive professional capital. 相似文献

This article reveals the multiple ways in which data are constituted as a vehicle for governing teachers’ work and learning. Drawing on the concept of governance, including in relation to the sociology of numbers, and data from one school in Queensland, Australia, the research reveals how teachers’ work and learning were constituted through practices of: establishing specific ‘targets’, including various ‘audacious goals’ for school and national testing; focusing upon ‘aligning’ all forms of school, regional and national data collected within the school; and participating in various ‘data conversations’ about specific students with senior members of staff. While the research reveals how teachers found such practices beneficial for improving their practice with students, it also shows how this learning was always and everywhere framed within a broader discourse of data, and how this data-centric focus came to constitute what was valued about their work and learning, and that of their students. 相似文献

This paper reveals the significant historical traces which informed the learning practices of teachers at one particular school site in a rural and regional educational district in Australia. Drawing upon recent theorising into professional practice, the paper argues that teacher learning practices are intrinsically ‘ecologically’ related to teachers’ practices at specific sites. However, extending beyond this theorising, the research also reveals how teacher learning – in the case presented, in relation to classroom dialogue – is also significantly influenced by earlier learning experiences of the teachers involved. In this way, teachers’ practices are revealed as not only influenced by present-day, site-specific, whole-school teacher learning, but also by particular events encountered by teachers at an earlier phase of their careers. The research argues for a conception of teachers’ learning which is not only site-informed and ecologically arranged, but also deeply temporally embedded. 相似文献
