Classroom Climate,Cardiac Vagal Tone,and Inhibitory Control: Links to Focused Attention in First Graders

The present study aimed to investigate the role of classroom climate and self‐regulation in terms of cardiac vagal tone and inhibitory control in primary school students' focused attention. A combination of direct and indirect measures was used to assess classroom climate, sustained and selective attention, and inattention behaviors among 62 first graders. We also registered students' cardiac vagal tone at rest and their levels of inhibitory control in a reaction time task. A single underlying factor combining sustained and selective attention as well as (the lack of) inattention behaviors accounted for students' focused attention. A regression analysis revealed that classroom climate, cardiac vagal tone, and inhibitory control interacted to explain first graders' focused attention. In classrooms with a negative climate, high levels of inhibitory control attenuated the negative effect of low cardiac vagal tone on students' ability to remain focused during classroom activities. Implications for theory and practice are discussed.     

Sorting on GPUs for large scale datasets: A thorough comparison

Although sort has been extensively studied in many research works, it still remains a challenge in particular if we consider the implications of novel processor technologies such as manycores (i.e. GPUs, Cell/BE, multicore, etc.). In this paper, we compare different algorithms for sorting integers on stream multiprocessors and we discuss their viability on large datasets (such as those managed by search engines). In order to fully exploit the potentiality of the underlying architecture, we designed an optimized version of sorting network in the K-model, a novel computational model designed to consider all the important features of many-core architectures. According to K-model, our bitonic sorting network mapping improves the three main aspects of many-core architectures, i.e. the processors exploitation, and the on-chip/off-chip memory bandwidth utilization. Furthermore we are able to attain a space complexity of Θ(1). We experimentally compare our solution with state-of-the-art ones (namely, Quicksort and Radixsort) on GPUs. We also compute the complexity in the K-model for such algorithms. The conducted evaluation highlight that our bitonic sorting network is faster than Quicksort and slightly slower than radix, yet being an in-place solution it consumes less memory than both algorithms.     

Self‐regulation strategies improve self‐discipline in adolescents: benefits of mental contrasting and implementation intentions

Adolescents struggle with setting and striving for goals that require sustained self‐discipline. Research on adults indicates that goal commitment is enhanced by mental contrasting (MC), a strategy involving the cognitive elaboration of a desired future with relevant obstacles of present reality. Implementation intentions (II), which identify the action one will take when a goal‐relevant opportunity arises, represent a strategy shown to increase goal attainment when commitment is high. This study tests the effect of mental contrasting combined with implementation intentions (MCII) on successful goal implementation in adolescents. Sixty‐six 2nd‐year high school students preparing to take a high‐stakes exam in the fall of their third year were randomly assigned to complete either a 30‐minute written mental contrasting with implementation intentions intervention or a placebo control writing exercise. Students in the intervention condition completed more than 60% more practice questions than did students in the control condition. These findings point to the utility of directly teaching to adolescents mental contrasting with implementation intentions as a self‐regulatory strategy of successful goal pursuit.     

Wer liegt am Ende der Grundschulzeit vorn?

The number of students enrolled in private schools has been growing continuously in the past years, especially in elementary schools. There is a variety of reasons for this development. Among other expectations, parents anticipate a superior education for their children and hope for bigger academic success. However, empirical results on the effectiveness of private schools are inconsistent and ambiguous, partly because many studies used cross-sectional data. Longitudinal studies investigating the development of elementary school students are especially lacking.The present study compares academic achievement gains of students enrolled in public schools to students who learned in the so-called BIP-creativity elementary schools. BIP schools are private schools that aim to promote the development of the talent, intelligence and personality of their students. This study investigates the development of students in mathematics, reading and orthography over a 4-years period.As the group of BIP-students is selected in terms of their socio-economic background, analyses were run in two ways. First, multilevel analyses controlling for student and class characteristics were performed. Second, a Propensity Score Matching based on school enrollment data was used in order to select a comparable group of students from public schools. Each BIP-student was matched to a student from the public schools that had a comparable socio-economic background and similar cognitive characteristics. Neither multilevel analyses nor mean comparisons of the matched samples could reveal any differences between the two groups of students in the three domains of academic achievement at the end of fourth grade.     

Validation of the Attitude-Older Adult and Aging-Visual Analogue Scales (At-O-A)

ABSTRACT

Occupational therapy programs have been developed in order to promote health in older adults. However, no published studies have yet been identified for the Spanish population. This study explores the benefits of an occupational therapy health promotion program called EnvejeHaciendo (AgeDoing). The study was conducted with 15 elderly Spanish adults, examining health perception and meaningful occupational participation using the Model of Human Occupation, as well as the pedagogical methodology See, Judge, Act. The results showed an increase in the perception of health with reference to social functioning and the number of roles in which the participants wanted to get involved in the future. The participants changed their own negative perception of elderly people, they adapted to the changes provoked by aging, and they got involved in meaningful activities such as physical exercise or social activities. This program allowed participants to engage in meaningful occupations with other people and to increase perceived health status through raising awareness of difficulties.     

Language learning and antiracism: some pedagogical challenges

It is often argued that the study of a foreign language can influence the attitudes and behaviour of learners. One of the goals of language teaching is to challenge stereotypes and encourage learners to engage with the cultural forms that can be accessed through a new language. Through learning a language it is hoped that learners will draw on their experiences to reflect critically on their own cultures and identities. We set out to examine these claims with respect to an advanced Open University French course for adult speakers of English. This article reports on a documentary analysis of the course materials for a particular unit and of a very small opportunity sample of student work and tutor comments. The unit sets out to provide a positive view of France as a multicultural society. The analysis focuses on the extent to which the materials and the tasks help learners engage with issues of racism, xenophobia, antiracism and human rights. We found that issues of race and racism are not presented in their complexity and that the materials and learning tasks unwittingly tend to reinforce stereotyped views. We suggest that attention should be given to helping students develop skills of intercultural evaluation. This requires an understanding of human rights on the one hand and of the various forms and manifestations of racism and xenophobia on the other. We conclude by proposing some guidelines for course writers and teachers that invite them to include a range of perspectives, including those of minorities. This attention to materials and pedagogy should enable students to engage critically with issues of race, identity and culture as they learn a foreign language.     

Enhancing motor learning through dyad practice: contributions of observation and dialogue

It has been shown that practice in dyads, as compared to individual practice, can enhance motor learning and increase the efficiency of practice (as two participants can be trained at the same time; Shea, Wulf, & Whitacre, 1999). The dyad practice protocol used by Shea et al. included both observation and dialogue between partners. Thus, it was not clear whether the learning benefits of dyad practice were due to observation, dialogue, or both. The present study examined the individual and interactive effects of observation and dialogue. The task used was speed cup stacking. Participants practiced under one of four conditions: observation/dialogue, observation/no dialogue, no observation/dialogue, and no observation/no dialogue. The two conditions that included observational practice were more effective (i.e., produced faster movement times) than the two conditions without it, both during practice and on a retention test performed under individual performance conditions. This suggests that the learning advantages of dyad practice are primarily due to the opportunity to observe another learner.
