Many museums offer specialized programs for young people during out‐of‐school time, yet the consequences of such programs are not well documented. This article explores the potential utility of borrowing a conceptual framework from the youth development literature as a tool for assessment. The authors map findings from three studies of museum youth programs onto the youth development framework as an exercise in understanding the extent to which this model may be useful in developing museum youth programs. Results from this preliminary analysis demonstrate that the framework could serve as a viable tool for program design, and could offer a clear, grounded framework with common language for articulating program impacts often known intuitively and/or anecdotally but not formalized.  相似文献

Abstract

Assessment for learning (AfL) practices are commonly recommended as effective classroom strategies for providing teachers with information about student understanding. For teachers, the substantive potential of these AfL practices to inform student learning actions depends on what teachers notice and select as a focus and how they interpret and act on the information they have. This paper suggests research on teacher professional noticing has something to offer in understanding how teacher AfL attention and actions are framed in the moment. It explains noticing as a responsive act that invites action that is an inclusive, dynamic and purposeful response to evidence of student ideas. Noticing is what enables a teacher to act on the fly because it informs and underpins possible actions. Three frames of noticing are introduced to guide noticing and action – curriculum connoisseurship, cultural and community connectedness, and collaborative ways of working. Through consideration of classroom events using these frames, teachers become better prepared to choose to respond in the moment creatively. The three frames provide teachers and researchers with a conceptual language to articulate and sharpen their AfL practices as part of a flexible and rigorous responsiveness to their students’ learning.  相似文献

The present study investigates the role of attitudinal variables, such as children's literacy interest and parents’ reading beliefs, in conjunction with home literacy activities (HLA), in predicting children's print‐concept knowledge. The objective of the study is to test a theoretical model describing the relationship among these variables. This study involved 551 low‐income preschool children. Structural equation modelling was used to test the model. The model was a good fit for the data when parental teaching of reading/writing was used as the measure of HLA. In the model, negative parent reading beliefs and parent teaching predicted print‐concept knowledge. Results suggest that practitioners should consider not only the literacy activities children and parents participate in, but also their attitudes towards those activities.  相似文献

BackgroundProfessional health organizations are not currently recommending Tai Ji Quan alongside aerobic exercise to treat hypertension. We aimed to examine the efficacy of Tai Ji Quan as antihypertensive lifestyle therapy.MethodsTai Ji Quan interventions published in English and Chinese were included when they involved healthy adults, reported pre- and post-intervention blood pressure (BP), and had a non-exercise/non-diet control group. We systematically searched 11 electronic databases for studies published through July 31, 2018, yielding 31 qualifying controlled trials. We (1) evaluated the risk of bias and methodological study quality, (2) performed meta-regression analyses following random-effects assumptions, and (3) generated additive models representing the largest possible clinically relevant BP reductions.ResultsParticipants (n = 3223) were middle-aged (56.6 ± 15.1 years of age, mean ± SD) adults with prehypertension (systolic BP (SBP) = 136.9 ± 15.2 mmHg, diastolic BP (DBP) = 83.4 ± 8.7 mmHg). Tai Ji Quan was practiced 4.0 ± 1.4 sessions/week for 54.0 ± 10.6 min/session for 22.3 ± 20.2 weeks. Overall, Tai Ji Quan elicited significant reductions in SBP (–11.3 mmHg, 95%CI: –14.6 to –8.0; d+ = –0.75) and DBP (–4.8 mmHg, 95%CI: –6.4 to –3.1; d+ = –0.53) vs. control (p < 0.001). Controlling for publication bias among samples with hypertension, Tai Ji Quan trials published in English elicited SBP reductions of 10.4 mmHg and DBP reductions of 4.0 mmHg, which was half the magnitude of trials published in Chinese (SBP reductions of 18.6 mmHg and DBP reductions of 8.8 mmHg).ConclusionOur results indicate that Tai Ji Quan is a viable antihypertensive lifestyle therapy that produces clinically meaningful BP reductions (i.e., 10.4 mmHg and 4.0 mmHg of SBP and DBP reductions, respectively) among individuals with hypertension. Such magnitude of BP reductions can lower the incidence of cardiovascular disease by up to 40%.  相似文献
