ABSTRACT The demands on mathematical problem-solving have increased in almost all school systems internationally and may constitute a barrier for children with special educational needs (SEN). This study explored the role of fluid reasoning (FR), working memory (WM) and complex executive function of planning (EF) in children (N = 62) referred for assessment of SEN, and specifically of risk for mathematical difficulties (MD). Performances on FR, WM and complex EF of planning were used to predict risk for MD. Results showed that planning ability predicted children at risk for MD, beyond FR or WM ability, when comparing with children not at risk for MD. It was concluded that assessing the complex EF of planning in addition to FR and WM ability is crucial in identifying children at risk for MD. The importance of understanding how planning ability affects children’s mathematical problem-solving is discussed, in relation to assessment and teaching practices. 相似文献

As teacher educators who have had extensive experience working in the field‐based secondary programs of two universities, the authors recognize the benefits, as well as the challenges, of forming partnerships with secondary educators to design and deliver collaboratively the teacher preparation program. In this article, experiences are shared and some of the major issues related to secondary teacher preparation that have been identified and contemplated are discussed. 相似文献

The current researchers investigated construct, predictive, and differential validity for the Comprehensive Receptive and Expressive Vocabulary Test (CREVT). Participants were 243 public school students, ages 5.5 to 17.25 years. They represented four primary disabilities: Learning Disability (n = 115), Learning Disability with Speech Impairment (n = 29), Mental Retardation (n = 40), and Speech Impairment (n = 59). Adequate construct validity for the CREVT was documented, using the Wechsler Intelligence Test for Children–III as a criterion. Also, the CREVT significantly predicted the scores on the Wide Range Achievement Test–3. Lastly, the CREVT effectively differentiated between students with disabilities. These findings suggest that the CREVT may be helpful in identifying the presence of learning problems. © 2002 Wiley Periodicals, Inc. Psychol Schs 39: 613–619, 2002. 相似文献

Abstract Three textiles with increasing compressive surface were compared with non-compressive conventional clothing on physiological and perceptual variables during sub-maximal and maximal running. Fifteen well-trained endurance athletes (mean ± s: age 27.1 ± 4.8 years, [Vdot]O2max 63.7 ± 4.9 ml · min?1 · kg?1) performed four sub-maximal (～70%[Vdot]O2max) and maximal tests with and without different compression stockings, tights, and whole-body compression suits. Arterial lactate concentration, oxygen saturation and partial pressure, pH, oxygen uptake, and ratings of muscle soreness were recorded before, during, and after all tests. In addition, we assessed time to exhaustion. Sub-maximal (P = 0.22) and maximal oxygen uptake (P = 0.26), arterial lactate concentration (P = 0.16; 0.20), pH (P = 0.23; 0.46), oxygen saturation (P = 0.13; 0.26), and oxygen partial pressure (P = 0.09; 0.20) did not differ between the types of clothing (effect sizes = 0.00–0.45). Ratings of perceived exertion (P = 0.10; 0.15), muscle soreness (P = 0.09; 0.10) and time to exhaustion (P = 0.16) were also unaffected by the different clothing (effect sizes = 0.28–0.85). This was the first study to evaluate the effect on endurance performance of different types of compression clothing with increasing amounts of compressive surface. Overall, there were no performance benefits when using the compression garments. 相似文献

Science programmes which prepare students to read critically and respond thoughtfully to science-based reports in the media
could play an important role in promoting informed participation in the public debate about issues relating to science, technology
and society. Evidence based guidance about the practice and pattern of use of science-based media in the classroom is limited.
This study sought to identify learning intentions that teachers believe ought to underpin the development of programmes of
study designed to achieve this end-result. Teachers’ views of knowledge, skills and attitudes required to engage critically
with science-based news served as a basis for this study. Teachers developed a pedagogical model by selecting appropriate
statements of learning intentions, grouping these into coherent and manageable themes and coding them according to perceived
level of difficulty. The model is largely compatible with current curricular provision in the UK, highlights opportunities
for interdisciplinary collaboration and illustrates the developmental nature of the topic. 相似文献

The present study was undertaken to examine scatter analysis and Kaufman regroupings of WISC-R scores. Thirty-one non-learning-disabled children (NLD) and 29 learning-disabled children (LD) determined by individual IQ and achievement scores served as subjects. Scatter indices were computed within the Verbal and Performance subtests as well as between the Verbal and Performance IQ scales. Also, the regrouping categories proposed by Kaufman (1979) were examined. A significant difference in Verbal and Performance IQs was found between the LD and NLD group. Significantly more students in the LD group exhibited the Kaufman regrouping pattern than in the NLD group (p < .01). These results suggest that Kaufman regroupings and Verbal-Performance scatter analysis may be used to assist in diagnosing LD children. 相似文献

This paper describes the development of an innovative resource, comprising authentic newspaper articles and associated activities, designed to broaden the range of reading material available for use in the science classroom. Science teachers' response to the publication is discussed. The resource was very well received, indicating that, given appropriate material, science specialists demonstrate a willingness to use media text in their classrooms. However, while all viewed the publication as a valuable science resource and many saw its potential for promoting literacy through science, only a few recognised it as a vehicle for encouraging, among students, critical engagement with science in the media. This suggests that further intervention may be necessary if this outcome is to be achieved. 相似文献

Digital technology is increasingly central to our lives, particularly among young people. However, there remains a concern from government and businesses of a digital skills gap because many youths, especially girls, tend to be consumers rather than creators of technology. Drawing on 32 semi-structured interviews with digitally skilled teenagers (aged 13–19), this article investigates their digital career aspirations and examines how identities and discourses of gender can interact with the type of digital careers that are of interest to these youths. While it was found that digitally skilled young people still articulate traditional gendered discourses of digital competence, especially around technical abilities, the growing importance of creativity as a career pathway into digital technology is highlighted. Implications of the findings are discussed in relation to the new computing curriculum in England, which prioritises technical computing skills, and the discontinuation of Information and Communications Technology (ICT), which facilitates a broader usage of software and digital productivity. 相似文献
