Children referred for evaluation of learning impairment (LI, N =100) and a comparison group of nonreferred (NLI, N = 243) children were evaluated on a visual filtering task. The task was designed hierarchically to provide for evaluation of component operations-serial search, parallel search, decision, and response. With each additional processing demand, response times increased disproportionately for the LI group relative to the NLI group. Overall response time reliably predicted academic skills and cognitive ability, but was more strongly related to group membership. Thus, this nonverbal visual task is sensitive to a characteristic of children with learning problems over and above discrete academic and cognitive skills. Children with problems adapting to the demands of schooling may be distinguished by a disproportionate vulnerability to processing load. 相似文献

An eye-tracking study with 60 native Swedish speakers (18–30 years) was conducted to investigate the positive effects on learning outcomes predicted by the disfluency effect. Subtle low-pass filtering was used as a disfluency manipulation and compared with a control condition using regular text. The text was presented on four separate text presentation screens (TPSs), and eye movements were recorded. A free recall task was given 25 min later, and working memory capacity (WMC) was assessed to test if it would moderate learning outcomes. The disfluency manipulation had no effect on learning outcomes, total reading times on words or lines, first- or second-pass reading on lines, or average fixation durations. Moreover, the disfluency effect was not moderated by students’ WMC or self-reported prior knowledge of the topic. However, an adaptation to the disfluency manipulation was found. Total reading times on both words and lines were shorter in TPS 1 and 2 in the disfluency condition compared with the control condition, whereas reading times were longer in TPS 3 and 4. It is discussed if failures to replicate the disfluency effect arise from material features, with positive adaptations to disfluency (i.e., higher effort investment) possibly requiring more comprehensive materials. 相似文献

In the external evaluation of schools the technique of classroom observation belongs to the methodological standard repertoire. Nevertheless the measurement of quality of classroom teaching based upon selected lesson sequences, which are as a rule inspected only briefly, is fraught with a lot of methodological problems. Therefore it is relevant for a substantiated quality assurance to reveal problems in the measurement of quality of classroom teaching due to an implementation of adequate empirical methods. This is made possible by using the generalizability theory and the many-facet Rasch model. Analyses based upon data of the Hamburg school inspection point out that by using an appropriate data collection procedure rater effects in classroom observations turn out comparatively low at about nine percent of total variance. Furthermore analyses prove that it is insufficient to simply quantify the agreement among raters by using global reliability measures, but that it is necessary to check up on intra rater consistency for getting valid and in this way reliable results from classroom observations for the practice. 相似文献

This article draws from the experience of outdoor and experiential educators working in the context of a radical, long-term formal public education research project. One of the accidental findings from the research is that experienced outdoor educators may have particular pedagogical skills, likely honed by the contexts in which they work, that can be of use to mainstream educators trying to expand their pedagogical repertoire, teach outdoors or be more environmentally focused in their practices. The article begins by contextualising the Maple Ridge Environmental School Project, describing the researchers and methods and explaining how the research team came to their insights. A discussion follows of five pedagogical skills identified by the researchers that outdoor and experiential educators may possess which might be offered more clearly to classroom teachers and formal teacher training processes and/or be more clearly enunciated for those involved in formal and informal outdoor and experiential training contexts. 相似文献

This article describes certain less visible but very significant basic units which have arisen in the discipline of mathematics in Romanian universities in parallel to the highly visible structure of chairs, departments, faculties, laboratories, institutes, and the like. These units: study groups, seminars, and schools of thought have grown up around the work of certain talented, original, and prolific thinkers and have been perpetuated by the students of the latter. In particular, these units have been very successful in inculcating an attitude favourable to research in beginning students, even having stimulated some of them, including students still in high school, to undertake research projects which have given very interesting results. 相似文献

Prior research shows that short-term effects from preschool may disappear, but little research has considered which environmental conditions might sustain academic advantages from preschool into elementary school. Using secondary data from two preschool experiments, we investigate whether features of elementary schools, particularly advanced content and high-quality instruction in kindergarten and first grade, as well as professional supports to coordinate curricular instruction, reduce fadeout. Across both studies, our measures of instruction did not moderate fadeout. However, results indicated that targeted teacher professional supports substantially mitigated fadeout between kindergarten and first grade but that this was not mediated through classroom quality. Future research should investigate the specific mechanisms through which aligned preschool-elementary school curricular approaches can sustain the benefits of preschool programs for low-income children. 相似文献

The objective of this study was to identify the effects of mouth rinsing with a 6% and 16% carbohydrate solution (CHO) on time trial performance when compared to a 0% control (PLA) when in a fed state. Twelve recreationally active males underwent three trials by which they had to complete a set workload (600?±?65?W) in a fed state. Throughout each trial, participants rinsed their mouths with a 25?ml bolus of a 0% PLA, 6% or 16% CHO (maltodextrin) for every 12.5% of work completed. Rating of perceived exertion (RPE) and heart rate were recorded every 12.5% of total work. Performance times and power output improved significantly when using the 6% and 16% CHO versus the PLA trial (6% versus PLA, p?=?.002 and 16% versus PLA, p?=?.001). When comparing the performance times of the 6% to 16% CHO, no significance was observed (p?=?.244). There was no significant difference between heart rate levels or RPE values across the three trials. In conclusion, mouth rinsing with a 6% or 16% CHO solution has a positive effect on a cycling time trial performance undertaken in a fed state. 相似文献

Indicators and instruments for determining and measuring school quality within inspection systems are usually based on frameworks for inspection. These frameworks rely heavily upon school and teacher effectiveness research. Thus, a central assumption is that the effectiveness and improvement-oriented school conditions, as measured within an inspection, are related to student achievement. It is unclear if this assumption really holds true, as empirical evidence is still lacking. This study uses data from a random sampling of schools (n = 37) and teachers (n = 1663) and the achievement data from students (n = 23,943) to validate the interpretations and uses of school inspection results regarding the factor school leadership. The study follows Kane’s argument-based approach for validation. Results reveal that principals of schools with recurrent high student achievement very often demonstrate instructional leadership. It is evident that these principals are also leading in a fundamentally different way from principals in schools with lower achievement in that they lead with the specific school context in mind. The study demonstrates that it is possible to make inferences from scores provided by school inspections and to generalize from them. However, this generalizability does not extend to making extrapolations or decisions based on these scores. The analyses make it clear that providing feedback solely on the strengths and weakness of a school is insufficient when it comes to stimulating school improvement through inspection. 相似文献
