This article argues that there is a strong link between the pedagogy for inclusion and the pedagogy of environmental education and tries to identify any benefits that could be acquired by pupils when the school system tries to use environmental educational programmes to promote inclusion. The idea of promoting a school yard into a school garden is given as an example. The article suggests that outdoor education experiences can facilitate positive development of self‐esteem, peer to peer socialisation as well as teacher–student relationships and a positive attitude towards school. One might conclude that the rationale behind environmental education has much to offer to all of our pupils. 相似文献

Collaborative Filtering (CF) Systems have been studied extensively for more than a decade to confront the “information overload”
problem. Nearest-neighbor CF is based either on similarities between users or between items, to form a neighborhood of users
or items, respectively. Recent research has tried to combine the two aforementioned approaches to improve effectiveness. Traditional
clustering approaches (k-means or hierarchical clustering) has been also used to speed up the recommendation process. In this paper, we use biclustering
to disclose this duality between users and items, by grouping them in both dimensions simultaneously. We propose a novel nearest-biclusters
algorithm, which uses a new similarity measure that achieves partial matching of users’ preferences. We apply nearest-biclusters
in combination with two different types of biclustering algorithms—Bimax and xMotif—for constant and coherent biclustering,
respectively. Extensive performance evaluation results in three real-life data sets are provided, which show that the proposed
method improves substantially the performance of the CF process.

Entrance to Primary School seems to be one of the most difficult and important changes in early childhood education. In this study it is examined the extent to which the differences between home or nursery school and primary school may cause difficulties to children in their psychological adjustment to the first grade of schooling. It is also investigated to see if some pedagogical strategies can make smoother the child's transition to school. The research was conducted in Greece during the period 1992–1993. Subjects were 75 nursery teachers, 566 first grade primary school teachers and 566 parents with first grade children. All subjects completed a questionnaire in which they evaluated the differences between home and primary school and between nursery school and primary school, as well as some pedagogical strategies. The results are presented in the tables I-IV. It seems that the differences between the environment in which the child lives before school and the primary school environment are so different that entrance to school is problematic for the child's adjustment. Some pedagogical strategies, however, may make smoother the children's passing from pre-school to school. 相似文献

The study reported here concerns 4 years of collaboration between secondary school teachers and academic researchers, constituting
an emerging community of inquiry into mathematics teaching. In the article, the process of the forming of this community is
discussed, focusing on the reflective activity developed by its members as well as the tensions and conflicts that emerged
in the shaping of an inquiry identity by them. Furthermore, shifts in the mode of participation in the community and thus
learning gains of all members are identified, with the teachers gradually developing an awareness of teaching practice in
general, and the researchers becoming progressively acquainted with the reflexive relationship between inquiring into teaching
practice and teachers’ professional development. 相似文献

Abstract The aim of this study was to examine the deltoid muscle properties of the dominant and non-dominant arm of Greek professional male tennis players. Eight male tennis players (mean age 22.0 years, s = 3.2) were subjected to biopsy of the deltoid muscle of both arms. Adenosine triphosphate (ATPase) histochemistry and myosin heavy chain (MHC) composition were performed on the samples with homogenate electrophoresis. No significant differences were observed in the percentage of types I, IIa, IIab, and IIb muscle fibres between the deltoid muscles of the two arms. Types I, IIa, and IIx muscle fibres of the dominant and non-dominant deltoid muscles did not differ significantly for MHC isoform composition. Type IIab muscle fibres showed a similar cross-sectional area (CSA) percentage distribution between the two arms. The CSA percentage for types I, IIa, and IIb muscle fibers did not differ significantly between the dominant and the non-dominant arm. We conclude therefore that regular tennis training probably does not lead to any significant changes in the muscle fibre types of the dominant and non-dominant arms of elite tennis players. 相似文献

AbstractBasketball incorporates intense eccentric muscle activity that induces muscle microtrauma and an inflammatory response. This study investigated time-dependent inflammatory and performance responses during a weekly microcycle after a basketball match. Twenty elite-standard players underwent a trial that comprised a match followed by a 6-day simulated in-season microcycle. The trial was preceded by a control condition that did not have a match. Blood sampling and tests of maximal-intensity exercise performance and muscle damage occurred before each condition, immediately after the match and daily thereafter for 6 consecutive days. The match induced marked increases in heart rate, lactate, ammonia, glucose, non-esterified fatty acids and triglycerides. Performance deteriorated for 24–48 h after the match, whereas knee flexor and extensor soreness increased for 48 and 24 h post-match, respectively. Inflammatory (leukocytes, C-reactive protein, creatine kinase activity, adhesion molecules, cortisol, uric acid and cytokines) and oxidative stress (malondialdehyde, protein carbonyls, oxidised glutathione, antioxidant capacity, catalase and glutathione peroxidase) markers increased for ~24 h and subsided thereafter. Reduced glutathione declined for 24 h after exercise. These results suggest that a basketball match elicits moderate and relatively brief (~24–48 h) inflammatory responses, is associated with marked but short-lived performance deterioration, but is less stressful than other intermittent-type sports. 相似文献
