Responding to the declining trend in reading motivation in and beyond the elementary school years, the authors aimed to enhance late-elementary school students' autonomous reading motivation. Toward this end, the authors evaluated the influence of a teacher professional development grounded in self-determination theory on fifth-grade students' (n = 664) autonomous motivation for in-school and leisure-time reading. A quasi-experimental repeated measures design was set up with experimental and control conditions. The experimental condition consisted of teachers participating in a professional development workshop aimed at providing the knowledge and skills necessary to implement an autonomy-supportive and structuring teaching style, whereas the control condition included teachers who continued with their current teaching repertoire. Multilevel piece-wise growth analyses corroborated that students in the experimental group reported increased recreational autonomous reading motivation from pretest to posttest relative to the control group. Additional analyses made clear that boys in particular benefitted from their teachers' professional development. 相似文献

Rats were trained in the discrete-trial operant apparatus with single alternation of large reward and small reward or large reward and nonreward. followed by either transfer or extinction. The results showed that both groups acquired appropriate response patterning, that patterning is conditioned, and that the stimuli which control patterning are derived from reward conditions on immediately preceding trials. A modification of the sequential hypothesis of instrumental learning was proposed to account for the results. 相似文献

Dyslexia is a specific disorder of language development that mainly affects reading. Etiological researches have led to multiple
hypotheses which induced various diagnosis methods and rehabilitation treatments so that many different tests are used by
practitioners to identify dyslexia symptoms. Our purpose is to determine a subset of the most efficient ones by integrating
them into a multivariate predictive model. A set of screening tasks that are the most commonly used and representative of
the different cognitive aspects of dyslexia was proposed to 78 children from elementary school (mean age = 9 years ± 7 months)
exempt from identified reading difficulties and to 35 dyslexic children attending a specialized consultation for dyslexia.
We proposed a multi-step procedure: within each category, we first selected the most representative tasks using principal
component analysis and then we implemented logistic regression models on the preselected variables. Spelling and reading tasks
were considered separately. The model with the best predictive performance includes eight variables from four categories of
tasks and classifies correctly 94% of the children. The sensitivity (91%) and the specificity (95%) are both high. Forty minutes
are necessary to complete the test. 相似文献

The self‐teaching hypothesis suggests that knowledge about the orthographic structure of words is acquired incidentally during reading through phonological recoding. The current study assessed whether visual processing skills during reading further contribute to orthographic learning. French children were asked to read pseudowords. The whole pseudoword letter string was available at once for half of the targets while the pseudoword's sub‐lexical units were discovered in turn for the other half. Then memorisation of the targets’ orthographic form was assessed. Although most pseudowords were accurately decoded, target orthographic forms were recognised more often when the pseudowords entire orthographic sequence was available at once during the learning phase. The whole‐word presentation effect was significant and stable from third to fifth grades. This effect was affected neither by target reading accuracy nor by target reading speed during the learning phase. Results suggest that beyond recoding skills, the ability to process the entire orthographic letter string at once during reading contributes to efficient orthographic learning. 相似文献

Longitudinal studies provide unique opportunities but are also faced with several limitations. The purpose of this study was to document three of these issues ("imperfect" design, evolution of data collection methods, representativeness) by means of the Leuven Longitudinal Study on Lifestyle, Fitness and Health (LLSLFH). The LLSLFH (1969 - 2004) comprises observations on males between 12 and 18 years and at 30, 35, 40, and 47 years, and on females at 16 and 40 years. In the most recent phase of the study, spouses and offspring were also included. The different phases and evolving research questions throughout the LLSLFH required an appropriate adaptation of the research design. The associated evolution of data collection methods largely reflects the changing ideas about physical fitness, body composition, and physical activity, the continuing search for new and better measurement techniques, and the need for adaptations with age. Ongoing study participants are representative in terms of body composition and, except for adolescence in males, also physical activity. No straightforward answer can be given concerning physical fitness. In both sexes, socio-economic status is above average. When informed about the possible "pitfalls" of longitudinal research in advance, several measures could be taken to prevent or limit them as much as possible. 相似文献

Reliability and validity of the Flemish Physical Activity Computerized Questionnaire in adults 总被引:1,自引:0,他引:1

The purpose of this study was to investigate the test-retest reliability and concurrent validity of the Flemish Physical Activity Computerized Questionnaire (FPACQ) in employed/unemployed and retired people. The FPACQ was developed to assess detailed information on several dimensions of physical activity and sedentary behavior over a usual week. A triaxial accelerometer, the RT3 Triaxial Research Tracker (RT3), in combination with a written 7-day activity record, was used as the objective criterion measure. In employed/unemployed people, 2-week test-retest reliability for several activity variables calculated from the FPACQ was good to excellent with intraclass correlations (ICCs) ranging from .67 to .99. In retired people ICCs were lower but, except for time spent eating, still fair to excellent, ranging from .57 to .96. Except for time spent in leisure time activities for men and the average energy expenditure related to sports participation in women, correlations between the RT3 and the FPACQ generally supported the relative validity of the FPACQ for employed/unemployed people (r ranging from .37 to .88). Values for retired people were somewhat lower (r ranging from .15 to .85), but most variables still reached at least moderate correlations. Concerning absolute validity, the FPACQ generally overestimated physical activity and underestimated sedentary behavior compared to the RT3. From this study, it can be concluded that the FPACQ is a reliable and reasonably valid questionnaire for assessing different dimensions of physical activity and sedentary behavior. 相似文献

Based on an online ethnography study of 274 YouTube videos posted during the Virginia Tech or the Newtown massacres, this article discusses how users resort to participatory media during such mediatized events to create a digital spontaneous shrine. The assemblage of this sanctuary on a website hosting billions of user-generated contents is made possible by means of folksonomy and website architecture, and a two-fold social dynamic based on participatory commitment and the institutionalization of a collective entity. Unlike “physical” spontaneous shrines erected in public spaces, these digital shrines connect the bereaved with provocative or outrageous contributions, notably tributes from school shooting fans using participatory media to commemorate the killer’s memory. This side effect, generated by the technical properties of the platform, compromises the tranquility of the memorial and muddles the boundaries and the contents of such sanctuaries. 相似文献
