ABSTRACTThis study examines the role of social networking sites on the learning processes, teaching practices and professional development of secondary school teachers. By conducting observations and in-depth interviews with active participants, we present an ethnographic study of the Facebook group Teaching ideas secondary education [author’s translation], which is hosted and primarily employed by Flemish teachers. By drawing parallels between the study findings and the theory of affinity spaces we aim to gain greater insight into emerging group dynamics and social informal learning processes. According to respondents, the Facebook group has the potential to address teachers’ needs with respect to the exchange of teaching ideas, experiences and materials. The findings point to a number of emerging developments in the educational landscape, highlighting that social media environments present a new source of inspiration, and combined with a collaborative atmosphere are able to stimulate cross-fertilization, social informal learning processes and self-management and -reflection. We hold these findings up to the light of current education discourses. 相似文献

We evaluate the performance of the most common estimators of latent Markov (LM) models with covariates in the presence of direct effects of the covariates on the indicators of the LM model. In LM modeling it is common practice not to model such direct effects, ignoring the consequences that might have on the overall model fit and the parameters of interest. However, in the general literature about latent variable modeling it is well known that unmodeled direct effects can severely bias the parameter estimates of the model at hand. We evaluate how the presence of direct effects in?uences the bias and efficiency of the 3 most common estimators of LM models, the 1-step, 2-step, and 3-step approaches. Furthermore, we propose amendments (that were thus far not used in the context of LM modeling) to the 2- and 3-step approaches that make it possible to account for direct effects and eliminate bias as a consequence. This is done by modeling the (possible) direct effects in the first step of the stepwise estimation procedures. We evaluate the proposed estimators through an extensive simulation study, and illustrate them via a real data application. Our results show, first, that the augmented 2-step and 3-step approaches are unbiased and efficient estimators of LM models with direct effects. Second, ignoring the direct effects leads to biased estimates with all existing estimators, the 1-step approach being the most sensitive. 相似文献

Organizational actorhood is a term that has gained prominence in literature about higher education as a way to describe some of the key global change processes with emphasis on organizational accountability, formalization of structure, focus on goal definition and managerialism. At the same time, there is less knowledge about how organizational actorhood is constructed in professional higher education institutions. Based on over 100 interviews and document studies of two case institutions, this article argues that professional higher education institutions show many characteristics of aiming to construct organizational actorhood, while their understanding of accountability is broader than would be in traditional comprehensive universities. 相似文献

This paper reports results from two studies aimed at examining whether perception of social acceptance and actual social acceptance
differ according to the presence of an illusion of scholastic incompetence. Results of both studies conducted in Belgium and
in Quebec (respectively 179 and 543 participants) show that children’s illusion of scholastic incompetence is linked to a
negative perception of social acceptance. However, according to the evaluation by peers, social acceptance of those children
is similar to the others. This suggests a generalization of the negative bias of self-evaluation to both academic and social
domains. The discussion proposes further variables that could improve the understanding of the origin of the illusion of incompetence. 相似文献

The health habits of today's children will largely determine their subsequent health as adults of the twenty-first century. Smoking, inactivity, poor dietary practices, drug and alcohol abuse, and other deleterious habits may develop early, yet exert lifelong influences. This paper contains a review of (a) statistics and research on major health status indicators in school-aged children, (b) behaviors that contribute to disease risk, and (c) school-based interventions designed to change risk behaviors and enhance wellness. Activities that can be initiated by classroom teachers are emphasized in the concluding section of the paper. Through early intervention, enhanced longevity and quality of life may be accomplished. 相似文献

Evidence is presented of the different cultural and ecological contexts affecting early child care for families of color. It is argued that improvements on previous research require a fundamental shift in how race, ethnicity, and culture as psychological variables are examined. Furthermore, to avoid the pitfalls and failures of previous research, new research must incorporate expanded models of child care and development in childhood. The integrative model of development for children of color proposed by Garcia Coll et al. (1996) is presented as a basis for developing more specific ecological models relevant to addressing child care issues in ethnic minority families. Finally, priority areas for future research are recommended to stimulate and enable child care researchers to adopt a more inclusive view of child care and its effects. 相似文献

Two experimental studies examined the effects of different types of phonemic segmentation training on phonemic segmentation, reading and spelling. Children with learning disabilities, who were weak in phonemic segmentation, were trained with the use of diagrams and alphabet letters, with alphabet letters only, or with no visual support at all (the control condition). For this purpose three computer-assisted training programs were developed. In the first experiment, 48 children were assigned to one of the three programs. The training period lasted five weeks. Although in each training program the children improved their phonemic segmentation skill, there were no significant differences among the three training programs. This result may have been influenced by the different types of feedback that were provided in the three training programs. In a second experiment, therefore, these differences in feedback were eliminated and 49 different children were trained with the same three programs. The results of this experiment, however, were the same as those of the first experiment. The finding that visual support had no beneficial effects could therefore not be attributed to differences in explicit feedback. It was concluded that with these children, in contrast to preschoolers, phonemic segmentation training using visual support does not have any advantage over auditory training alone. The results of this study indicate that preschoolers and children with reading and spelling problems cannot be treated in the same way. It underlines the importance of further examination of the problems that poor readers and poor spellers encounter in grasping the structure of spoken language. 相似文献
