Music and mathematics require abstract thinking and using symbolic notations. Controversy exists regarding transfer from musical training to math achievements. The current study examined the effect of two integrated intervention programs representing holistic versus acoustic approaches, on fraction knowledge. Three classes of fourth graders attended 12 lessons on fractions: One class attended the ‘MusiMath’ holistic program (n = 30) focusing on rhythm within the melody. Another class attended the ‘Academic Music’ acoustic program (Courey et al., Educ Stud Math 81:251, 2012) (n = 25) which uses rhythm only. The third class received regular fraction lessons (comparison group, n = 22). Students in both music programs learned to write musical notes and perform rhythmic patterns through clapping and drumming as part of their fraction lessons. They worked toward adding musical notes to produce a number (fraction), and created addition/subtraction problems with musical notes. The music programs used a 4/4 time signature with whole, half, quarter and eighth notes. In the math lessons, the students learned the analogy between musical durations and fractions, but also practiced fractions other than . Music and math were assessed before, immediately following, and 3‐ and 6‐months post‐intervention. Pre‐ to post‐intervention analyses indicated that only the ‘MusiMath’ group showed greater transfer to intervention‐trained and untrained fractions than the comparison group. The ‘Academic Music’ group showed a trend on trained fractions. Although both music groups outperformed the comparison group 3‐ and 6‐months post‐intervention on trained fractions, only the ‘MusiMath’ group demonstrated greater gains in untrained fractions. Gains were more evident in trained than in untrained fractions. A video abstract of this article can be viewed at https://youtu.be/uJ_KWWDO624 相似文献

Factors that contribute to children’s walking to school have been investigated in previous research, which primarily focussed on socio-economic variables in high income countries. There is a general lack of studies which have examined mode choice differences on school trips in low and middle income countries. Focusing on parental social cognitive variables in addition to household socio-economic characteristics, the present study is among the first to compare barriers to children’s walking in daily commuting to schools across samples from two middle income countries: Iran and China. A self-administered questionnaire was devised and distributed among primary school pupils (7–9 years old) in Mashhad, Iran and Nanjing, China. The children were asked to take the questionnaires to their parents to complete and return the filled forms. A total of 671 (response rate of 90 percent) and 224 (response rate of 82 percent) completely filled questionnaires were returned in Mashhad and Nanjing, respectively. Multivariate analysis of covariance (MANCOVA) showed that parents in Mashhad perceived higher risk and reported more worry of children being involved in road crashes when walking to school. Analyses revealed more safety favourable parental attitudes in the Chinese sample, compared to the Iranian sample. Parental attitudes towards transport safety were safer in the sample from Nanjing as compared to Mashhad. Hierarchical binary logistic regression showed that walking time from home to school and parental worry about road crashes were negatively associated with children’s walking to school in both samples. In the Iranian sample, results suggested that while household car ownership and higher family income were associated with a decreased probability that a child walk to school, the total number of children in the household increased the probability of walking to school. 相似文献

Maltese counsellors working in schools are, at times, just making ends meet due to lack of human resources and work schedules. ‘Why do our students/children have to repeat the same story to so many professionals?’ teachers/parents angrily query. This autoethnographic study voices our professional experiences as authors and participants. This empowers us to be advocates for our young clients. Collaborative autoethnography (CAE) methodology best fits our research question as we ‘seek to discover and systemically analyze (graphy) personal experience (auto)…understand cultural experience (ethno)’ (Ellis, Adams, & Brochner, 2011, p. 273). Our writing and reflections conclude that best practices include counsellors who work, at least, in pairs within transdisciplinary teams at one school for cycles of five years, with clarity of roles across professionals. 相似文献

Abstract Public health agencies regularly survey randomly selected anonymous students to track drug use, sexual activities, and other risk behaviors. Students are unidentifiable, but a recent project that included school-level analysis discovered a school with alarmingly prevalent student suicidality. Given confidentiality protocols typical of surveillance, the surveyors were uncertain whether and how to intervene. We searched literature for duties to warn at-risk groups discovered during public health surveillance, but we found no directly applicable guidance or cases. Reasoning by analogy, we conclude that surveyors should contact the school’s leaders to call attention to its outlier status, but public warning is unwarranted. However, such an ad hoc decision to issue a warning, even if only to school leaders, raises significant practical, legal and ethical issues. National public health and education associations should produce guidance that clarifies ethical and legal duties owed to schools and students involved in population health-risk surveillance. 相似文献

AbstractBackground: Transgender and non-binary children and young people and their parents in England, UK are poorly served across a range of healthcare settings. Whilst UK equalities legislation and international guidance on transgender healthcare pathways protects this group from discrimination and mandates an affirmative approach, services in England are not keeping pace.Aims: This study aims to draw on the experiences of transgender and non-binary children, young people and their parents in a support group in England in order to investigate their experiences of healthcare provision, and to develop some ideas for improvement.Method: Data was collected with participants in a family support group which offers a parent helpline service, social groups for children and parents, and training for schools and other organizations. 65 parents and children from 27 families from the family support group attended participatory workshops where they were given a range of briefs: “health,” “family,” “friends,” and “education.” Their participation involved being asked to define their own interview questions and collect data by interviewing each other. Their interview notes constituted the raw data. Data was coded inductively by the author with respondent checking as a second stage.Results: Results constitute the views of a small group of people, so cannot be generalized. However, they do illustrate some of the issues which may arise. Participants’ experiences elicited five key themes: professionals’ perceived lack of clinical and therapeutic knowledge; mental distress caused by excessive waiting lists; professionals’ stereotyped gender assumptions; direct discrimination within healthcare settings; and a lack of attention to parent and child voice, especially in terms of school-based experiences and where a patient had a diagnosis of autism. 相似文献

Commensurate with the serious risks bullying poses to students’ mental health, substantial attention has been devoted to evaluating school bullying prevention programs. Research on the effectiveness of these interventions shows mixed outcomes. Recent evidence suggests that even programs that reduce overall bullying may have negative outcomes for victims. Most bullying prevention programs incorporate a range of strategies, but we know little about which strategies actively reduce bullying and whether some may have iatrogenic effects. Questions have been raised about programs that involve working with peer bystanders and whether some strategies stigmatize victims. In this article, I propose three theoretically derived hypotheses that describe mechanisms through which encouraging peers to actively defend victims may produce adverse outcomes for victims. More research is needed to test these hypotheses. A deeper understanding of the differential impact of bullying prevention strategies will lead to improvements in programs and more targeted use of effective strategies. 相似文献

Organized after‐school programs can mitigate risk and build resilience for youth in urban communities. Benefits rely on high‐quality developmental experiences characterized by a supportive environment, structured youth–adult interactions, and opportunities for reflective engagement. Programs in historically disenfranchised communities are underfunded; staff are transient, underpaid, and undertrained; and youth exhibit significant mental health problems which staff are variably equipped to address. Historically, after‐school research has focused on behavior management and social‐emotional learning, relying on traditional evidence‐based interventions designed for and tested in schools. However, after‐school workforce and resource limitations interfere with adoption of empirically supported strategies and youth health promotion. We have engaged in practice‐based research with urban after‐school programs in economically vulnerable communities for nearly two decades, toward building a resource‐efficient, empirically informed multitiered model of workforce support. In this paper, we offer first‐person accounts of four academic–community partnerships to illustrate common challenges, variability across programs, and recommendations that prioritize core skills underlying risk and resilience, align with individual program goals, and leverage without overextending natural routines and resources. Reframing obstacles as opportunities has revealed the application of mental health kernels to the after‐school program workforce support and inspired lessons regarding sustainability of partnerships and practice. 相似文献

Although researchers have developed prevention programs to reduce bullying, the results are mixed, and this may be due to a degree of uncertainty in their theoretical foundation. In particular, these programs share an emphasis on empathy as a personal attribute that can be enhanced among students through the application of specific curricula that will, in turn, contribute to a reduction in bullying behavior. However, the link between empathy and bullying is unclear, as is the ability of bullying prevention programs to actually impact student empathy. In this study, we used a cluster randomized trial (N = 15 middle schools, 1,890 students, 47.1% female, 75.2% White) to evaluate the impact of cooperative learning on bullying, and we evaluated whether these effects were mediated by empathy and peer relatedness. Our results indicated that cooperative learning can significantly reduce bullying, and that some of this effect is transmitted via enhancements to affective empathy. Cooperative learning also demonstrated significant positive effects on cognitive empathy, but this did not have an effect on bullying. We also found that the effects of cooperative learning on cognitive and affective empathy were mediated by improvements in peer relatedness. These findings add a degree of clarity to the literature, and also represent the first time, as far as we are aware, that an antibullying program has been found to have significant effects on both cognitive and affective empathy. 相似文献
