We report on a project currently in progress that aims to identify through research the range of factors (individual, school
and out-of-school, including home) and their interactions that influence post-16 (i.e. post-compulsory) participation in mathematics
and physics in the UK and to assess their relative importance among different student populations. In this project, we are
beginning to elucidate the views of students and examine the sources of these views by exploring the contexts in which both
school and university students experience barriers or opportunities and form their identities with regard to participation
in mathematics and physics. Our focus in this paper is on our methodology, the reasons for it and how and why our approach
to data collection developed during the project. We situate our work within a mixed-methods approach, using multilevel modelling
and discourse analysis to analyse and interpret our findings that derive from our own questionnaires, interviews and ethnography
and from existing large-scale datasets. We argue that greater acknowledgement in the education literatures that investigate
student participation in mathematics and science needs to be made than is usual of the range of factors, including unconscious
forces that may affect participation. 相似文献

This prospective longitudinal study evaluated changes in psychological distress among adolescents, pre-pandemic to intra-pandemic, the extent to which within-person and between-person differences in trait multidimensional perfectionism were associated with such changes, and the role of stress in explaining associations between perfectionism and psychological distress. Adolescents (N = 187; 80% female; 78% White, 7% Asian Canadian, 2% Indigenous Peoples in Canada, 2% Black or African Canadian, 2% Latin Canadian, or 9% Other; Mage = 17.96 years) completed online surveys assessing perfectionism (i.e., self-oriented perfectionism and socially prescribed perfectionism), depression, anxiety, and stress pre-pandemic (i.e., March 12, 2020 or earlier) and during Ontario, Canada's first (i.e., March 13, 2020 to July 24, 2020) and second (December 26, 2020 to February 7, 2021) government-mandated lockdowns. Between-person differences and within-person changes in multidimensional trait perfectionism were associated with increases in psychological distress and perceived stress. Perceived stress served as an intermediary pathway linking multidimensional trait perfectionism to psychological distress during the pandemic. 相似文献

This study examined interparental conflict as a curvilinear predictor of children's reactivity to interparental conflict and, in turn, their school problems across three annual measurements. Participants included 243 preschool children (Mage = 4.60 years; 56% girls) and their parents from racially (e.g., 48% Black; 16% Latinx) diverse backgrounds. Interparental conflict was a significant quadratic predictor of children's emotional reactivity (β = .23) and behavioral dysregulation (β = .27) to conflict over a 1-year period. The robust association between interparental conflict and behavioral dysregulation weakened at high levels of interparental conflict. In contrast, interparental conflict more strongly predicted children's emotional reactivity as conflict exposure increased. Children's emotional reactivity, in turn, predicted their greater school problems 1 year later (β = .25). 相似文献

Internationally, there is a gap in high-school completion rates for Indigenous and non-Indigenous students. In Australia, gap estimates are commonly based on lag indicators, precluding examination of underlying mechanisms. Using two longitudinal representative samples of Australian youth, we explored differences in high-school completion between Australian Indigenous and non-Indigenous rates, and whether the gap varies for students of similar academic ability. Using an intersectional approach, we show the Indigenous gap is significant, is mostly a function of differences in academic achievement, but varies by socioeconomic status (SES) and location. Specifically, high SES and living in urban settings are protective factors for non-Indigenous students, but not for Indigenous students. Conversely, rural and poor non-Indigenous students appeared to have dropout rates as large or even larger than similarly poor and rural Indigenous youth. Overall, the results suggest the need for a more nuanced perspective on ‘Indigenous gaps’ in educational attainment. 相似文献

Games may be useful tools for learning and communicating about sexual and reproductive health. This article discusses the collaborative design and subsequent evaluation of a narrative-based card game. This game was created in a workshop based on positive youth development, which allowed youth to be involved as game designers and game players. Human-centered design informed the workshop and gave the youth opportunities to have meaningful roles, learn skills, and focus on an issue that affects their peers. The intervention was constructed to teach about sexual and reproductive health and also to provide skills to address the medical, social, and emotional aspects of sexually transmitted infections (STIs). During the evaluation of the resultant game, student players were critical of the game but admitted to learning essential facts about STIs. This study demonstrates the feasibility of collaboratively designing a game with youth for youth resulting in a playable and educational tool. 相似文献

This study examined the relationship of 979 middle school students’ perceptions of their mathematics classroom environment to their motivation and achievement. Structural equation modeling indicated that motivational variables (utility, personal achievement goals, efficacy) mediated the influence of perceived teacher expectations, teacher support and use of reform practices on mathematics standardised test scores. Our study provides empirical evidence that students’ perceptions that their teachers believe that they are capable of learning and understanding mathematics positively relate to their Mastery and Performance Goal orientations and mathematics Utility. Further, we found an interaction between students’ perceptions of the frequency of reform practice use in their mathematics classroom and mathematics efficacy. For students with lower mathematics efficacy, their perceptions of more frequent use of reform practices in their mathematics class related to higher standardised test performance. For students with higher mathematics efficacy, perceived use of reform practices did not significantly relate to standardised test performance. These data suggest that frequent exposure to reform practices is especially critical for students who judge themselves as being less capable in mathematics and who are lower performers. This finding differs from prior research that has suggested that reform practice use benefits higher achievers but not lower achievers. An important implication of our study is the need for coordinated, ongoing professional development that highlights reform pedagogy and beliefs while also focusing on student motivation theories and strategies. 相似文献

Background:Literature searches underlie the foundations of systematic reviews and related review types. Yet, the literature searching component of systematic reviews and related review types is often poorly reported. Guidance for literature search reporting has been diverse and, in many cases, does not offer enough detail to authors who need more specific information about reporting search methods and information sources in a clear, reproducible way. This document presents the PRISMA-S (Preferred Reporting Items for Systematic reviews and Meta-Analyses literature search extension) checklist, and explanation and elaboration.Methods:The checklist was developed using a three-stage Delphi survey process, followed by a consensus conference and public review process.Results:The final checklist includes sixteen reporting items, each of which is detailed with exemplar reporting and rationale.Conclusions:The intent of PRISMA-S is to complement the PRISMA Statement and its extensions by providing a checklist that could be used by interdisciplinary authors, editors, and peer reviewers to verify that each component of a search is completely reported and, therefore, reproducible. 相似文献

Abstract The aim of this study was to examine participant and scheme characteristics in relation to access, uptake, and participation in a physical activity referral scheme (PARS) using a prospective population-based longitudinal design. Participants (n = 3762) were recruited over a 3-year period. Logistic regression analyses identified the factors associated with the outcomes of referral uptake, participation, and completion (≥80% attendance). Participant's age, sex, referral reason, referring health professional, and type of leisure provider were the independent variables. Based on binary logistic regression analysis (n = 2631), only primary referral reason was associated with the PARS coordinator making contact with the participants. In addition to the influence of referral reason, females were also more likely (odds ratio 1.250, 95% confidence interval 1.003 – 1.559, P = 0.047) to agree to be assigned to a leisure provider. Referral reason and referring health professional were associated with taking up a referral opportunity. Older participants (1.016, 1.010 – 1.023, P < 0.001) and males were more likely to complete the referral. In conclusion, the PARS format may be less appropriate for those more constrained by time (women, young adults) and those with certain referral reasons (overweight/obesity, mental health conditions). More appropriate targeting at the point of referral could improve participation rates by revealing or addressing barriers that might later result in dropout. 相似文献
