The Effects of Extinction in the Treatment of Sleep Problems with a Child with a Physical Disability

Sleep problems are common among young children with developmental disabilities. In many cases, parental attention has shaped and reinforced these problems. In the present study, extinction of parental attention was effective in the elimination and long-term maintenance of nighttime crying with a young child with a physical disability.     

Deafness and attention in deaf children

The study shows the differences between hearing parents and deaf instructors interacting with deaf children and directing their attention. Data were collected at home and at a service for special needs in Bristol, England. The mother or instructor was asked to play naturally with the child with the toys provided. When the child's attention was focused during their play, the mother or instructor had to try to direct the child's attention to each of the toys. The results suggest that both groups (mothers and instructors) were effective in directing attention to objects not in the immediate area of play; however, hearing mothers were more successful than deaf instructors.     

A longitudinal analysis of gender differences in academic self-concept and language achievement: A multivariate multilevel latent growth approach

This study investigated the development of academic self-concept and language achievement from Grade 7 to Grade 12 by repeated assessment of 2826 Flemish adolescents in 50 secondary schools. Latent growth curve modeling showed that both girls and boys experience a declining academic self-concept during the period of secondary education and that girls declined at a faster rate. Furthermore, girls were shown to have an increase in Dutch language achievement over time, whereas boys showed a decrease in middle years, followed by an increase from Grade 9 on. The multivariate multilevel growth curve model suggested that the evolution of academic self-concept was not related to the evolution in achievement, neither at the individual level, nor at the school level. There is, however, a positive relation between students’ academic self-concept and their achievement, the magnitude of which decreased throughout secondary school. At the school level, the correlation is small, but also positive, except for the girls from Grade 10 on. The results are discussed in relation to the reciprocal effects model and the developmental perspective regarding the self-concept/achievement relation.

An experimental,video-based investigation into the motivating impact of choice and positive feedback among students with different motor competence levels

ABSTRACT

Background: Research stemming from Self-Determination Theory (SDT) shows that physical education (PE) teachers who endorse an autonomy-supportive and structuring motivating style positively affect students’ motivation, engagement and learning. Choice provision and positive feedback are two concrete strategies that are part of an autonomy-supportive and structuring style, respectively. While the benefits of choice provision and positive feedback have been shown in contexts other than PE, evidence in the specific context of PE is much scarcer. Grounded in SDT and relying on experimental design, the present study sought to examine the effects of choice provision and positive feedback on students’ motivational experiences in PE, and whether these effects were moderated by students’ actual motor competence (AMC).

Method: A sample of 277 students (41% boys, Mage?=?12.78 years) was randomly assigned to one of four experimental conditions (2?×?2 design). Prior to the experimental manipulation, participants’ AMC was measured with the Test of Gross Motor Development second edition. Participants then watched a videotaped PE lesson, in which the provision of choice (choice – no choice) and type of feedback (corrective feedback – positive and corrective feedback) were manipulated. Participants were asked to imagine how they would feel being a student in the displayed lessons. After watching the video, they completed validated questionnaires on their (1) anticipated need satisfaction and frustration and (2) autonomous and controlled motivation. MANOVAs were conducted to investigate the differences between the experimental groups in terms of anticipated need satisfaction, need frustration and motivation. Multiple linear regression analyses were used to examine the potential moderating role of AMC.

Findings and conclusions: The benefits of choice provision were clearly shown with students in the choice condition anticipating significantly more autonomy, competence and relatedness satisfaction and autonomous motivation, while they anticipated significantly less autonomy and relatedness frustration when compared to students in the no choice condition. Similarly, the addition of positive feedback to corrective feedback yielded clear benefits, with lower averages in anticipated need frustration found among students who watched the videos in which positive feedback was added to corrective feedback. No support was provided for a synergetic motivational effect between choice and positive feedback. Overall, the present findings show the importance of offering choice and providing positive feedback to motivate students in PE, with positive effects being present for all students independent of their initial AMC levels. Although few interaction effects were found, lowly motor competent students benefited even more from receiving positive feedback than highly motor competent students. The findings of this study are important to take into account in PE teacher education programs and professional training programs for PE teachers about how to teach in a (more) motivating way.     

Teaching portfolios in higher education and their effects: An explorative study

Although many authors claim benefits of teaching portfolios for use in higher education settings, there are few empirical studies that investigate these benefits.This article deals with the question of whether teaching portfolios are used in higher education, and if so, which effects they bring about. Furthermore, the attitude of teachers towards the use of teaching portfolios is examined. The study shows that currently not very many teachers are using teaching portfolios. When used, a teaching portfolio is an instrument that can bring about some important positive effects. Respondents report that, due to the use of portfolios, they were stimulated to reflect on their own teaching, to actualise the learning content, to improve their course materials, to search for alternative educational methods, etc. When teachers are using teaching portfolios it is important that, besides any negative effects, they also experience positive effects. If this is not the case, teachers will see the teaching portfolio only as an extra administrative inconvenience.     

Hybrid clustering for validation and improvement of subject-classification schemes

A hybrid text/citation-based method is used to cluster journals covered by the Web of Science database in the period 2002–2006. The objective is to use this clustering to validate and, if possible, to improve existing journal-based subject-classification schemes. Cross-citation links are determined on an item-by-paper procedure for individual papers assigned to the corresponding journal. Text mining for the textual component is based on the same principle; textual characteristics of individual papers are attributed to the journals in which they have been published. In a first step, the 22-field subject-classification scheme of the Essential Science Indicators (ESI) is evaluated and visualised. In a second step, the hybrid clustering method is applied to classify the about 8300 journals meeting the selection criteria concerning continuity, size and impact. The hybrid method proves superior to its two components when applied separately. The choice of 22 clusters also allows a direct field-to-cluster comparison, and we substantiate that the science areas resulting from cluster analysis form a more coherent structure than the “intellectual” reference scheme, the ESI subject scheme. Moreover, the textual component of the hybrid method allows labelling the clusters using cognitive characteristics, while the citation component allows visualising the cross-citation graph and determining representative journals suggested by the PageRank algorithm. Finally, the analysis of journal ‘migration’ allows the improvement of existing classification schemes on the basis of the concordance between fields and clusters.
