ABSTRACTWhen searching for information on the Internet, it can be stored in a bookmarking system. The ability to organize this information in such a system depends on one’s own prior knowledge to create an appropriate classification scheme. Providing a classification system for bookmarks might support people with low prior knowledge. Even though different bookmarking systems exist, hierarchical menus and tagging are being most widely used. In the current exploratory study with 95 ninth-grade students, a 2 × 2 between-subjects design was used to investigate the influence of providing classification support (or not) for either a tagging or a hierarchical system. Results showed that despite the low familiarity with tagging systems, using a hierarchical system is not necessarily a better approach than using a tagging system to organize previously found information. Rather, a tagging system seems to yield storage of fewer but higher-quality information sources. The most important conclusion is that, despite the low familiarity with tagging systems, using a hierarchical system was not beneficial over using a tagging system to organize previously found information. 相似文献

The main aim of this study was to develop standardised tests that assess some of the most important spelling skills for children in primary school: sound-letter mappings (non-lexical spelling) and word spelling accuracy (lexical spelling). We present normative comparison data for children in Grades 1–7 as well as measures of validity and reliability for both tests. Another aim of this study was to assess the relative prevalence of spelling difficulties that only affect one skill selectively (only lexical or only non-lexical spelling) or both. We found that throughout Grades 1–7, children were as likely to have selective as they were to have mixed difficulties. This underscores the importance of measuring lexical and non-lexical skills separately. The tests presented in this paper provide teachers and clinicians with the necessary tools to do exactly that. 相似文献

This study investigated whether task instructions affect sound-isolation performance. The effects of phoneme class and phoneme position were also assessed. Two hundred Dutch kindergartners were presented with a free-sound-isolation task and its constrained counterparts: an initial-, a middle-, and a final-sound-isolation task. All tasks contained 17 CVC words. Children's performance on the free-sound-isolation task was better than on the constrained tasks. On all four tasks, children made fewer errors in isolating the initial phoneme than the final phoneme. Isolating the middle phoneme proved to be the most demanding. The effect of phoneme class depended on the type of task and on phoneme position. Findings were placed against the background of sonority and word-final phoneme vocalization in Dutch. 相似文献

The goal of this study was to determine whether it is possible to teach children with serious decoding problems four text comprehension strategies in listening contexts. The subjects were 9-11 year old students from special schools for children with learning disabilities. All the students were very poor at decoding; half of the group were also poor listeners, whereas the other half consisted of normal listeners. The experimental children were trained in strategies of clarifying, questioning, summarising and predicting through a combination of reciprocal teaching and direct instruction. The results indicated significant programme effects on a strategic listening comprehension test. A transfer effect on general listening comprehension and general reading comprehension tests was not found. The poor listeners within the experimental group did not perform better than the normal listeners. 相似文献

This study examined the value of using a group‐centered approach to evaluate process quality of early childhood education and care (ECEC). Is observed support of group processes a different aspect of classroom quality, and does it predict children's collaborative play in ECEC in the Netherlands? In two play situations, 37 teachers and 120 two‐ to four‐year‐old children were observed with the Classroom Assessment Scoring System (CLASS) Toddler and two new measures. In a two‐level structural equation model, teachers’ support of group processes was positively related to the CLASS domains and to children's collaborative play, over and above the effect of children's cognitive ability and social competence. These findings suggest that ECEC quality evaluation could be enriched by adding group‐centered indicators of classroom quality. 相似文献

The relationship among students' reading performance, their behavior (task-focused behavior, emotional stability, and compliant behavior) in the classroom, and the teacher's skills was investigated in 66 third-grade classrooms. Results from this study showed the students' reading performance and their behavior in the classroom are all significantly interrelated. Better reading performance at the beginning of the school year goes with better behavior at the end of the school year. In turn, better behavior at the beginning of the school year goes with better reading performance at the end of the school year. The teacher can improve the behavior of the students by providing high-quality reading instruction. Some teacher skills have differential effects, however, on the various behavioral aspects. The implications for the educational practice as well as for future research are discussed. 相似文献

Background:Physical activity(PA)has substantial health benefits and is important in combatting chronic diseases,which have been associated with elevated levels of advanced glycation endproducts(AGEs).AGEs play a role in the aging process,and an association between PA and AGEs has been reported.We aimed to investigate the relationship between PA and AGE accumulation in a general population and in a population with chronic diseases.Methods:This large cross-sectional population study used data from adult participants in the LifeLines project,with participant information drawn from the LifeLines database as well data from patients with diabetes mellitus or renal and/or cardiovascular diseases.Tissue AGE accumulation was assessed non-invasively by skin-autofluorescence(SAF)using an AGE reader(DiagnOptics Technologies BV,Groningen,the Netherlands).PA was assessed using the short questionnaire to assess health-enhancing physical activity(SQUASH).Multivariate linear regression analyses were adjusted for age,body mass index,sex,and smoking status.Results:Data from 63,452 participants(general population n=59,177,chronic disease n=4275)were analyzed.The general population was significantly younger(43.58±11.77 years,mean±SD)and had significantly lower SAF(1.90±0.42 arbitrary units(AU))compared to the population with chronic disease(age:55.51±12.07 years;SAF:2.27±0.51 AU).In the group with chronic disease,more hours of moderate to vigorous physical activities per week were associated with lower SAF(β=-0.002,95%confidence interval(95%CI):-0.002 to-0.001).For the general population,there was no association between hours of moderate to vigorous activity and SAF(β=3.2×10-5,95%CI:0.000-0.001,p=0.742).However,there was an association in the general population between total hours of PA per week and SAF(β=4.2×10-4,95%CI:0.000-0.001,p<0.001),but this association was not found in the chronic disease population(β=-3.2×10-4,95%CI:-0.001 to 0.000,p=0.347).Conclusion:Our study demonstrates that an inverse relationship exists between PA and AGE accumulation in the population with chronic disease.More hours of moderate to vigorous activity is associated a significantly decreased SAF.More PA is associated a lower SAF,even after for the established predictors(age,body mass index,smoking status,and sex).Our findings could help to promote health and prolong longevity. 相似文献

The implementation of peer assessment receives much attention in teacher education. This paper reports the effects of peer assessment training on the performance of student teachers. Ninety-three student teachers were randomly assigned to control groups and experimental groups. The experimental groups were trained in defining performance criteria, giving feedback and writing assessment reports. This was done through peer assessment tasks that were embedded in a redesigned course. Analyses of data derived from peer assessment reports written by the students showed that the experimental groups surpassed the control groups in the quality of the assessment skill. As a result of the training, students from the experimental groups also scored significantly higher grades for the end products of the course than students from the control groups. The results of the questionnaire showed that all students were significantly more satisfied with the redesigned course. 相似文献
