Concept-guided development of technology in ‘traditional’ and ‘innovative’ schools: quantitative and qualitative differences in technology integration     

Sandra de Koster  Monique Volman  Els Kuiper 《Educational technology research and development : ETR & D》2017,65(5):1325-1344

The integration of technology into the classroom remains a challenge for those involved. A concept-guided approach to the development of technology has been suggested as a way of meeting this challenge. This multiple case study was performed in the context of a project in which five elementary schools in The Netherlands with a school concept that was labeled as either ‘traditional’ or ‘innovative’ developed and realized up to four technology-supported learning arrangements in line with their schools’ educational concepts. Through embedded case studies, including analysis of the learning arrangements and focus group interviews with the teachers involved, we found that in general the developed technology use became integrated in the teachers’ classroom practices at all schools to a similar extent. Some differences were found between the schools, but hardly any were found between the school types. Both practical and theoretical implications of these findings are discussed.  相似文献   

Mid-career academic women and the prestige economy     

Camille B. Kandiko Howson  Kelly Coate  Tania de St Croix 《高等教育研究与发展》2018,37(3):533-548

Drawing on 30 semi-structured interviews with women academics based in London higher education institutions in the UK, this paper investigates the gendered nature of the prestige economy in academia. We explore how mid-career academic women strategise their career development and the opportunities and barriers they perceive, particularly in relation to the accrual of academic esteem. Concept maps were used to facilitate dialogue about career plans and provided an artefact from the interviewee’s own perspective. The analysis draws on the concept of prestige, or the indicators of esteem that help advance academic careers, against the backdrop of a higher education context which increasingly relies on quantitative data to make judgements about academic excellence. The interviews indicated that women generally feel that men access status and indicators of esteem more easily than they do. Many women also had ambivalent feelings about gaining recognition through prestige: they understood the importance of status and knew the ‘rules of the game’, but were critical of these rules and sometimes reluctant to overtly pursue prestige. The findings are valuable for understanding how women’s slow access to the highest levels of higher education institutions is shaped by the value that organisations place on individual status.  相似文献   

Developmental Relations Between Reading Comprehension and Reading Strategies     

Marloes M. L. Muijselaar  Nicole M. Swart  Esther G. Steenbeek-Planting  Mienke Droop  Ludo Verhoeven  Peter F. de Jong 《Scientific Studies of Reading》2017,21(3):194-209

We examined the developmental relations between knowledge of reading strategies and reading comprehension in a longitudinal study of 312 Dutch children from the beginning of fourth grade to the end of fifth grade. Measures for reading comprehension, reading strategies, reading fluency, vocabulary, and working memory were administered. A structural equation model was constructed to estimate the unique relations between reading strategies and reading comprehension, while controlling for reading fluency, vocabulary, and working memory. The results showed that there was a unique effect of reading strategies on reading comprehension, and also of reading comprehension on reading strategies.  相似文献

萝卜硫烷对脑线粒体的影响:机理观点和未来发展方向     

Fernanda Rafaela JARDIM  Fhelipe Jolner Souza de ALMEIDA  Matheus Dargesso LUCKACHAKI  Marcos Roberto de OLIVEIRA 《Journal of Zhejiang University. Science. B》2020,21(4):263-279

有机硫化物萝卜硫烷(SFN)是一种有效的细胞保护剂,在体外和体内实验模型中均可促进抗氧化、抗炎、抗糖化和抗菌作用。因为氧化磷酸化系统的存在,所以线粒体是三磷酸腺苷(ATP)的主要产生部位。同时,线粒体也是具核人体细胞中产生活性氧的主要场所。线粒体损伤在多种人类疾病中起着重要作用,包括神经退行性病变和代谢异常。本文描述和讨论了SFN调节哺乳动物细胞中线粒体功能和动力学的作用和机理,以及其对肿瘤细胞中线粒体促凋亡途径的促进作用。SFN对线粒体的调节作用使得它在一定程度上被认为是一种细胞保护剂。本文还指出了几个需要通过进一步实验解决的问题,即未来的可能研究方向,这可能会对该领域的研究人员具有指导作用。  相似文献   

El profesor como práctico reflexivo en una cultura de colaboración     

Luis Miguel Villar Angulo  P. de Vicente Rodriguez  A. Bolivar Botia  E. Molina Ruiz  M.J. Leon Guerrero  M.J. Gallego Arrufat 《欧洲师范教育杂志》1994,17(3):187-206

The aim was the reconstruction of a school curriculum in reflective teaching situations within a co‐operative culture. Two working assumptions were considered: (a) teacher development was based on teacher thinking and (b) school organisation followed a co‐operative culture paradigm. The process features were: (a) university team consisted of external advisers; (b) school curriculum and classroom instruction were reviewed by school teachers; (c) case study as a research approach; (d) ethnographic techniques to collect data; (e) data analysis by a computer program; (f) teachers’ reflective cycle to reconstruct practice; and (g) teachers’ portfolios: narrative vignettes, etc. Findings showed: (a) a collaborative process school‐university; (b) teachers’ thinking and attitudinal change; (c) mobilisation of teachers’ talents and values to work together: (i) teacher dyads to reflect on teaching; (ii) advisers’ writing narrative vignettes; (Hi) collegial coaching; and (iv) curriculum materials designed by teachers. Two conclusions can be accepted: (a) teachers’ pedagogical practical knowledge showed diversity of their implicit theories to design action; and (b) teachers’ grounded theory confirmed that the educational action was based on a co‐operative and reflective culture.  相似文献

陈寅恪论(下)     

蔡仲德 《南阳师范学院学报》2003,2(4):16-19

通过对陈寅恪学术贡献与学术观点的评估、对陈寅恪人格特征与化取向的剖析、对陈寅恪研究中几个问题的讨论、对全面评价陈寅恪的若干思考，可得出结论，陈寅恪存在理智与情感的尖锐矛盾，理智上能清醒地看到中国旧化必然歇绝的历史命运，情感上却无法摆脱对此化的深深眷恋。不仅陈寅恪的《诗集》，而且陈寅恪的全部作，都是对这一化的余音不绝的挽歌。陈寅恪的思想基础不是人本主义。而是民族主义、国家主义，他所追求和维护的不是“天下万世之真理”，而是囿于一时间(前现代)、一地域(封建中国)的终将归于不可救疗之局的纲常名教。陈寅恪不是一个真正的自由主义，而是一个坚定的保守主义。  相似文献   

Superlatent inhibition and spontaneous recovery: Differential effects of pre- and postconditioning CS-alone presentations after long delays in different contexts     

R. E. Lubow  L. G. de La Casa 《Learning & behavior》2002,30(4):376-386

In two pairs of three-stage conditioned taste aversion experiments, we examined the effects of delay interval (1 or 21 days) between the second and third stages, and of context in which the animals spent the delay (same as or different from the context of the other stages) on latent inhibition (LI) and spontaneous recovery following extinction. In the LI experiments (Experiments 1A and 1B), the first stage comprised nonreinforced presentations to saccharin or to water. In the second stage, rats were conditioned by saccharin paired with LiCl. In the extinction experiments (Experiments 2A and 2B), the order of the stages was reversed. For all experiments, Stage 3, the test stage, consisted of three presentations of saccharin alone. There was a super-LI effect in the saccharin-preexposed group that spent the 21- day delay in the different context (Experiment 1A). When the delay was spent in the same context, there was no difference in the amount of LI between the short- and long-delay groups (Experiment 1B). Conversely, there was a spontaneous recovery effect in the long-delay/same-context group (Experiment 2B), but not in the long-delay/different-context group (Experiment 2A). The pattern of results, incompatible with current explanations of delay-induced changes in memory performance, was interpreted in terms of an interaction between the delay conditions (same or different delay context), which modulate the extinction of previously acquired context-CS-nothing associations (during CS-alone presentations), and primacy effects.  相似文献   

The historic approach in teaching: Analysis of an experience     

Ruth S. de Castro  Anna Maria Pessoa de Carvalho 《Science & Education》1995,4(1):65-85

The main purpose of this paper is to report our first attempts to study how and where it is possible to use the history of physics in a high school course. We made four activities based on historical data connected to heat and temperature. Filming was extremely important for the type of study we made since it allowed to draw out the situations we considered most relevant whenever necessary. We selected and analysed all the episodes in which there was any allusion (explicit or not) to history, presented in the form of questions or doubts, or portraying explanations of facts and phenomena built up based on reconstructions provided by the historical approach.  相似文献
