Physical Activity and School Performance: Evidence from a Danish Randomised School-Intervention Study

It has been claimed that physical activity has a positive effect on not only health but also on school performance. Using data from a randomised school-intervention study, this paper investigates whether different interventions promoting physical activity affect school performance in primary school children. The results indicate that on average, the interventions have a very limited beneficial impact on the pupils’ performance. The effects are mostly insignificant, and in some cases even negative. These results are relevant when considering how general school resources and resources targeted towards physical activity in particular should be invested to improve school performance.     

Free and reduced-price meal enrollment does not measure student poverty: Evidence and policy significance

Free and reduced-price meal (FRM) enrollment is commonly used in education research and policy applications as an indicator of student poverty. However, using multiple data sources external to the school system, we show that FRM status is a poor proxy for poverty, with enrollment rates far exceeding what would be expected based on stated income thresholds for program participation. This is true even without accounting for community eligibility for free meals, although community eligibility has exacerbated the problem in recent years. Over the course of showing the limitations of using FRM data to measure poverty, we also provide early evidence on the potential value of two alterative measures of school poverty.     

The role of output speech in literacy acquisition: Evidence from congenital anarthria

A case study of literacy acquisition in acongenitally speechless child (SM) isreported. In spite of a complete oral apraxia(due to bilateral focal brain damage), SMdeveloped normal intelligence and acquired complete mastery of reading and writing skills.Furthermore, both his verbal memory andmetaphonological skills were surprisinglypreserved. However, he showed a relativeimpairment in writing non-words. Theimplications of these findings for thedevelopmental interactions between language andliteracy are discussed.     

The development of audiovisual speech perception in Mandarin-speaking children: Evidence from the McGurk paradigm

The developmental trajectory of audiovisual speech perception in Mandarin-speaking children remains understudied. This cross-sectional study in Mandarin-speaking 3- to 4-year-old, 5- to 6-year-old, 7- to 8-year-old children, and adults from Xiamen, China (n = 87, 44 males) investigated this issue using the McGurk paradigm with three levels of auditory noise. For the identification of congruent stimuli, 3- to 4-year-olds underperformed older groups whose performances were comparable. For the perception of the incongruent stimuli, a developmental shift was observed as 3- to 4-year-olds made significantly more audio-dominant but fewer audiovisual-integrated responses to incongruent stimuli than older groups. With increasing auditory noise, the difference between children and adults widened in identifying congruent stimuli but narrowed in perceiving incongruent ones. The findings regarding noise effects agree with the statistically optimal hypothesis.     

Discouraged Children: when praise does not help

Teachers are now legally required to provide effective education for the 'more difficult-to-teach' children, and both the 1994 Code of Practice and the DfE circulars on Pupils with Problems stress 'teacher enablement' as an element in whole-school development policies. Gerda Hanko, author and SEN staff development tutor, examines the kind of in-service provision appropriate to the needs of 'discouraged children', who are not motivated by praise.     

Intrafamilial sexual abuse: brother-sister incest does not differ from father-daughter and stepfather-stepdaughter incest

OBJECTIVE: Three groups of girls who were sexually abused (by either brothers, fathers, or stepfathers) were compared. The purpose was to identify the differing characteristics of the abuse, the family environments, and the psychosocial distress of these children. METHOD: Seventy-two girls aged between 5 and 16 were assigned to one of the three groups. Subjects were matched between groups on the basis of their actual age. Children completed measures of traumatic stress; their mothers completed the Child Behavior Checklist-Parent Report Form (CBCL) and other self-report questionnaires on family characteristics. Workers in child protective services completed information regarding the nature and severity of the abuse. RESULTS: Results suggested few differences in the characteristics of sexual abuse between the three groups. However, penetration was much more frequent in the sibling incest group (70.8%) than in the stepfather incest (27.3%) or father incest (34.8%) groups. Ninety percent of the victims of fathers and brothers manifested clinically-significant distress on at least one measure, whereas 63.6% of stepfather victims did. Compared with father and stepfather perpetrators, brothers were raised in families with more children and more alcohol abuse. CONCLUSIONS: The authors conclude that the characteristics of brother-sister incest and its associated psychosocial distress did not differ from the characteristics of father-daughter incest These findings suggest that theoretical models and clinical practices should be adjusted accordingly and that sibling incest should not necessarily be construed as less severe or harmful than father-daughter incest.     

Group work does not necessarily equal collaborative learning: evidence from observations and self-reports

Situative and sociocognitive analyses were combined to examine engagement in high-level collaborative learning and its relationship with individuals’ cognitions. Video footage of 53 science university students’ (nine groups) collaborative learning interactions as they worked through a case-based project was analysed in combination with students’ appraisals and reflections on the activity. Sizeable group differences in amount of high-level discussion of learning content were revealed. Individual high-level contributions were positively correlated with overall unit performance. Motivation at task onset predicted amount but not depth of content-related group discussion. Interviews with participants suggested that groups’ divergent patterns of engagement with content could be related to different perceptions of the notion of collaborative learning. Results are discussed in terms of implications for collaborative learning research and educational practice.     

Pictorial representations of simple arithmetic problems are not always helpful: a cognitive load perspective

This study examined immigrant parents’ involvement in early years mathematics learning, focusing on learning of multiplication in in- and out-of-school settings. Ethnographic interviews and workshops were conducted in an urban city in Japan, to examine out-of-school practices of immigrant families. Drawing from sociocultural theory of learning and the concept of appropriation (Wertsch, 1998), the role of power and identity was examined in relation to children’s appropriation of an informal multiplication method that was taught by their parents. An intergenerational analysis, between immigrant parents and their children, revealed heterogeneous perspectives towards appropriation. Immigrant parents in this study framed their involvement in their children’s early years mathematics learning in relation to their positional identities and the pressures to conform to the mainstream practices of their host country. During their early years of schooling, students in this study were already aware of academic tracking in the school and were aware of what was believed to be legitimate in school mathematics learning. The significance of diversifying mathematics curriculum and pedagogy was discussed to affirm the knowledge and identities of immigrant students and families.     

The boss is not always right: Norwegian preschoolers do not selectively endorse the testimony of a novel dominant agent

Theories of cultural evolution posit that cues of competence-based prestige, rather than formidability-based dominance, should guide culturally transmitted learning, but recent work suggested that French and Kaqchikel Guatamalan preschoolers place their epistemic trust in dominant others. In contrast, this study shows that 249 three- to six-year-olds (116 girls, tested between 2016 and 2018 across metropolitan locations with varying ethnic composition and socioeconomic status) randomly endorsed the word-labels of dominant and subordinate agents in the egalitarian culture of Norway, using stimuli which solicit dominance inferences among infants and manipulating anonymity across studies to control for egalitarian desirability bias. A meta-analysis estimated that 48% endorsed the dominant's testimony. This demonstrates that the tendency to endorse the epistemic claims of dominant individuals does not emerge reliably in early childhood.

Indeed,sometimes knowledge does not help: A replication study

In an earlier study we found that intermediate experts in the domain of economics did not surpass novices in complex learning and knowledge application with a computer-based business simulation. In the present study, it was investigated whether these contra-intuitive findings can be replicated. In order to scrutinize the reasons which led to these findings, some parameters of the learning environment were changed. The duration of the exploration phase and of the problem-solving phase as well as the complexity of the situations were increased, motivation and acquired declarative knowledge were assessed. In view of mastering recurring demands and the functionality of mental models, no differences were found between a group of novices (15 students of humanities with a supplementary training in economics) and a group of intermediate experts (13 advanced students of economics). The findings of the original study were replicated, motivation had no effect on the result. In terms of declarative knowledge, the novices turned out to be even better.     

“高宗谅阴”的“隐度”文化及古代“温仁”——兼论前谐声时代闭口韵向舌鼻韵演变趋势

先秦文献所记"高宗谅阴,三年不言",谓殷高宗守丧期间依礼制居茅庐,三年中不主动发表政治主张和意见。"谅阴"指孝子居丧住的茅庐,名称的理据有形制与思想文化两层。形制上密闭奄盖(阴)和通敞(凉),分别仿效故去的亲人殡与葬的居处特点,以己之感受度亲之感受,这是孝子对亲的居处的隐度。隐度是上古广泛存在的思想文化。凶庐初闭阖后启户的形制特点而称"谅阴",是因为深层上"谅阴"本身就具有隐度的意义。"隐度"之"隐"、"温仁"之"温",都取意于己与彼感受相覆合,词源就是"谅阴"之"阴"。"谅"也有两相对称、当值之义。古语词是古代思想文化的化石。"谅阴"深层思想文化内涵就是人与人之间、人与物之间、人与自然之间的"谅"(体谅)和"隐"(隐度),就是以己之情度彼之情。隐度是"温仁"的心理机制,"仁爱"的本质就是隐度其情。这是"天人合一"思想文化的一种重要内涵。用历史词汇比较与同语境相关词汇互证的方法证明,从前谐声时代到谐声时代,一批闭口韵字音变读作舌鼻韵(-m>-n,-p>-t/-?),"阴"变为"隐""温"是这种音变的表现。     

God does not play dice: causal determinism and preschoolers' causal inferences

Three studies investigated children's belief in causal determinism. If children are determinists, they should infer unobserved causes whenever observed causes appear to act stochastically. In Experiment 1, 4-year-olds saw a stochastic generative cause and inferred the existence of an unobserved inhibitory cause. Children traded off inferences about the presence of unobserved inhibitory causes and the absence of unobserved generative causes. In Experiment 2, 4-year-olds used the pattern of indeterminacy to decide whether unobserved variables were generative or inhibitory. Experiment 3 suggested that children (4 years old) resist believing that direct causes can act stochastically, although they accept that events can be stochastically associated. Children's deterministic assumptions seem to support inferences not obtainable from other cues.     

Gender difference does not mean genetic difference: Externalizing improves performance in mental rotation

The fear of underperforming owing to stereotype threat affects women's performance in tasks such as mathematics, chess, and spatial reasoning. The present research considered mental rotation and explored effects on performance and on regulatory focus of instructions pointing to different explanations for gender differences. Two hundred and one participants were asked to perform the Mental Rotation Test (MRT) and were told that men perform better than women. Then they were divided into four sub-groups and provided with no additional information (control condition) or one of three explanations: (a) genetic factors, (b) widely-held stereotype, or (c) time limit. A decrease in performance was predicted for the genetic instruction and an increase for the two alternative explanations based on externalizing. Results showed that both women and men are harmed by the genetic explanation and relieved by both the stereotype and the time limit explanations. Explanations stressing genetics and time limit as factors affecting performance favor prevention focus.     

One size does not fit all: Understanding the variation in charter management scale-up

The prevalence of charter management organizations (CMOs)—networks of charter schools overseen by a home office—has exploded in recent years but there is a paucity of research into how CMOs approach growth and the factors that influence their growth plans. In this qualitative study, we examine how a set of 25 older, more established CMOs approached growth. Findings suggest that strategies for scale-up varied depending on the external policy environment and the internal organizational capacity of the CMO. In addition, CMOs approached growth from one of three styles: premeditated, opportunistic, or organic. Finally, longitudinal data reveal that CMOs often struggled to meet their growth targets; fewer than half of the sample CMOs met or were on track to meet their projected scale-up targets. From these findings emerged a key source of tension: On one hand, CMOs are facing pressure from policymakers and foundations to grow and expand rapidly. On the other hand, scaling-up too quickly or in ways that fall outside of the CMO’s mission can lead to serious consequences for the organization, its schools, and students. Our research aims to contribute to this debate by demonstrating that “one size does not fit all” for CMO scale-up, a lesson important for policymakers, educators, and researchers alike.     

Overwrought copyright: Why copyright law from the Analog Age does not work in the Digital Age’s society and classroom

In this article, the authors argue that copyright law, conceived of in an “analog” age, yet made stricter in our present Digital Age, actively stifles creativity among today’s student creators, both by its bias toward content owners and its legal vagueness. They also illustrate that copyright law is too stringent in protecting intellectual content, because physical and virtual objects have different properties. They conclude with a call to revise copyright for new media content that meets the needs of both content creators and pre-existing media content owners, and that, most importantly, benefits the education of the creative and innovative mind in today’s mediacentric classrooms.     

Materialism does not pay: Materialistic students have lower motivation,engagement, and achievement

The aim of this study was to examine how materialism, or the focus on acquiring money and material possessions, is associated with students’ academic engagement and achievement via their motivational regulation (amotivation, controlled motivation, and autonomous motivation). Study 1 (n = 606 secondary students) was a cross-sectional study which found that materialism was negatively associated with engagement. This association was partially mediated by amotivation. Study 2 (n = 404 secondary students) was a longitudinal study which found that Time 1 materialism was negatively associated with Time 2 engagement and Time 3 academic achievement via amotivation. Results of the two studies provide converging lines of evidence that materialism is negatively associated with key indicators of learning. Students with high levels of materialism have lower levels of engagement and achievement, and these associations are partially mediated by amotivation. Theoretical and practical implications are discussed.
