Trastornos de aprendizaje en el niño con disfunción cerebral

RESUMEN

Los niños con disfunción cerebral son aquellos que sin padecer lesión cerebral aparente presentan problemas de tipo motórico, funcional y multidimensional. Los principales trastornos perceptivos son: la disociación, la inversión del campo sensorial y la perseverancia. Los trastornos de pensamiento más comunes son las relaciones conceptuales estereotipadas y formalistas, la falta inesperada de memoria y la dispersión de la atención. Dentro de los trastornos de conducta se observa la hiperactividad sensorial, la desinhibición motriz y las reacciones catastróficas con afectividad incontrolada. Algunas recomendaciones son la necesidad del diagnóstico precoz y la importancia de los servicios psicopedagógicos y de una enseñanza personalizada.     

Gender Differences on Research: The perceptions and use of academic time

In the last years, the increasing pressure over higher education institutions to promote alternative non‐state funding sources has lead to an increasing importance given to research and, more specifically to applied research. The notion that women dedicate less time to research may be seen in the new context, as a prominent threat for women to reach universities top positions. In this article, which draws from an exploratory study case of two public universities in Portugal, we examine whether there are gender differences on perceptions about time dedicated to different academic activities. Findings reveal no significant gender differences in the academics' perceptions about their work.     

Opportunities to Learn and Achievement in Mathematics in a Sample of Sixth Grade Students in Lima, Peru

In recent years, the mathematics achievement of Peruvian students has been evaluated in three national and two international studies. The results in all cases suggest very poor learning. A similar situation is found in many developing countries. In this study, we analyzed the opportunities to learn (OTL) mathematics of sixth grade students from 22 public schools in Lima, Peru. OTL were defined in this study as curriculum coverage, cognitive demand of the tasks posed to the students, percent of mathematical exercises that were correct and quality of feedback. These variables were coded in the workbooks and notebooks of the students, which were gathered at the end of the school year (at the same time, the mathematics achievement test was administered). The results show that: (a) regarding OTL, less than half of the exercises available in the workbooks were solved, teachers overemphasize some topics of the national curriculum ({i.e.} related to Number and Number Sense), they pose tasks that are at very low levels of cognitive demand, and it is common to find mistakes in the students' answers to problems that have no feedback (or even worse, the feedback is wrong); (b) students in relatively poorer, multigrade classrooms have less OTL; (c) OTL, as defined earlier, is positively associated with achievement.A preliminary version of this paper received the Research Medal in the category Knowledge, Education andTechnology at the Annual Meeting of the Global Development Network (GDN) in Cairo, in January 2003.     

The peak velocity derived from the Carminatti Test is related to physical match performance in young soccer players

ABSTRACT

The aim of this study was to examine the relationship between the peak velocity derived from the Carminatti Test (T-CAR) (PV_T-CAR) and physical match performance in young soccer players. Thirty-three youth soccer players were recruited from 2 non-professional clubs. Friendly matches and small-sided game were performed. Physical match demands were assessed using Global Positioning System (GPS) technology. On a separate occasion, the players were submitted to the T-CAR. Players were categorised into 3 groups based on their T-CAR performance: Low (PV_T-CAR ≤ P33), Intermediate (P33 > PV_T-CAR < P66) and High (PV_T-CAR ≥ P66). The PV_T-CAR (15.5 ± 0.7 km·h^?1) was significantly related to high-intensity activities (HIA; r = 0.78, P < 0.001), high-intensity running (HIR; r = 0.66, P < 0.001), sprinting (r = 0.62, P < 0.001) and total distance (TD) covered (r = 0.47, P < 0.01) during friendly matches. The PV_T-CAR was strongly correlated with the amount of HIA (r = 0.81, P < 0.001), HIR (r = 0.85, P < 0.001) and TD covered (r = 0.81, P < 0.001) during small-sided game. No significant correlation was observed between the PV_T-CAR and distance of sprinting (r = 0.49, P = 0.067) during small-side game. Furthermore, players in the High group covered significantly more TD (10%) and did more HIA (42%), sprinting (31%) and HIR (25%) during friendly matches compared to the players classified as having Low performance on the T-CAR. These differences still remained after adjusting for chronological age (CA), maturity and body size. In conclusion, the current study gives empirical support to the ecological and construct validity of this novel field test (T-CAR) as an indicator of match-related physical performance in young soccer players during pubertal years.     

Perceptions of quality in staff-student written feedback in higher education: a case study

This paper reports on the results of an embedded, multiple case study that investigated the views of both lecturers and students on written staff-student feedback in three postgraduate programmes at one UK university. The study sought to uncover how ‘quality written feedback’ is perceived in the higher education environment under investigation. It found that tutors and students were broadly aligned in the features that they identified as constituting quality, which could be categorised within three dimensions: the affective or interpersonal, the orientational and the transformational. The findings suggest that feedback needs to incorporate each of these dimensions if it is to be perceived as being of good quality.     

Self-Regulation Abilities and Spanish-Speaking Preschoolers’ Vocabulary and Letter-Word Skills in Spanish and English

Research Findings: This study examined the heterogeneity in Spanish-speaking children's (N = 117; M age = 53 months; SD = 5 months; 57% boys) vocabulary and letter-word skills in English and Spanish after one year of preschool and the extent to which early self-regulation abilities (i.e., executive function and effortful control) were associated with that variability. Data were gathered via teacher and parent surveys and standardized assessments. Three distinct profiles of Spanish-speaking preschoolers were identified using cluster analysis. One group exhibited high levels of Spanish and English vocabulary and letter-word skills (a.k.a. high-balanced bilinguals). The other two groups exhibited predominantly Spanish or English vocabulary and letter-word skills (a.k.a. Spanish- or English-dominant). Multinomial logistic regression analyses (controlling for children's nonverbal cognitive ability) revealed that effortful control skills enhanced children's probability of being classified as high-balanced bilinguals versus Spanish-dominant; however, this was evident only for the children whose parents reported speaking exclusively Spanish at home. Executive function abilities appeared to be unrelated to preschoolers' bilingual classification, and thus their English vocabulary and letter-word skills. Practice or Policy: The findings have implications for early education programs working to increase the school readiness of Spanish-speaking children by highlighting the key role that effortful control may play in supporting their learning of English skills, particularly for those whose parents speak exclusively Spanish at home.     

Issues and agency: postgraduate student and tutor experiences with written feedback

This paper examines the issues which postgraduate students and tutors experienced as they engaged in receiving, providing and requesting feedback, as well as the strategies which they adopted as they sought resolution of these issues. The study employed a case study approach, using data obtained from semi-structured and stimulated recall interviews with students and staff from three discipline areas at one university in the UK. The findings reinforce the conclusions that have been drawn in a number of previous studies in terms of the sources of dissatisfaction emerging from individual interactions and institutional practices. Additionally, however, the results expand on our current understanding of feedback and agency in higher education by illustrating how participants sought out imaginative solutions to the challenges they experienced, in order to enhance the effectiveness of the feedback process. The diversity of the strategies used provides evidence of student and tutor agency, and has implications for current feedback practices and future research in this area.
