ABSTRACT

Meta-analytic evidence supports that exercise has benefits for short-term memory (STM) and long-term memory (LTM). However, only three studies with children have tested the differential effects of exercise on STM and LTM. The purpose of this study was to examine the effects of an aerobic fitness test on STM and LTM and to consider the moderating effects of grade level. Children (7–13 years of age) were randomly assigned to either perform an aerobic fitness test before (exercise prior) or after (exercise post) performing the Rey Auditory Verbal Learning Test (RAVLT) to assess memory. Memory was tested again after approximately 24 hours. There were significant differences in memory performance as a function of grade with 4th and 6th graders consistently outperforming 2nd graders. For learning, Day 1 Retention, 24-hr recall, and Day 2 Retention, the exercise prior group performed better than the exercise post group. It is concluded that an aerobic fitness test performed prior to a declarative memory test benefits LTM as compared to when the aerobic fitness test is performed after the memory test.  相似文献

This study tests an ecological, relationship-based model of children's subjective well-being with 9- to 14-year-old children (= 25,906) from 14 countries across Africa, Asia, Europe, North America, and South America. Children completed the Children's Worlds survey, a self-report measure of contextual and well-being indicators. Multilevel modeling was used to predict children's well-being (life satisfaction and self-image) at two levels, child (age, gender, home context, family relationships, peer relationships, school context, teacher relationships, and neighborhood quality), and country (gross domestic product and income inequality). Findings indicated that intercepts varied significantly across countries. The majority of variance in children's well-being was attributed to child-level rather than country-level factors. Country-level factors did not strongly predict well-being but marginally improved model fit.  相似文献

ABSTRACT

The purpose of this article is to report on the implementation and initial evaluation of a 1-day training intervention targeting direct care providers in the Ohio aging services network. A primary objective is to describe the training intervention that consisted of two parts: (a) a gatekeeper training for assessing suicide risk among older adults, and (b) CALM (Counseling on Access to Lethal Means)—a brief training that teaches effective strategies to talk with clients about reducing access to lethal means. A second objective of this study is to report on changes in providers’ knowledge, attitudes, and practices immediately posttraining related to suicide and firearm assessment and safety counseling with community dwelling older adults. Sixty-six employees in one regional office participated in the study. Results indicated that training increased participants’ perceived knowledge, preparedness, and efficacy regarding suicide assessment. Training also positively impacted knowledge and attitudes of firearm assessment and safety counseling among participants. At posttest, however, gatekeeper reluctance did not demonstrate a significant decrease. This study is unique in its contribution to literature on suicide prevention training with its focus on geriatric care providers and attention to measuring firearm assessment and safety counseling.  相似文献

Abstract

This case study presents the efforts of three high school teachers to design and implement climate change lessons in alignment with the Next Generation Science Standards (NGSS). Using three conceptual frameworks that organize the assumptions of the environment in the NGSS we examine how those assumptions influence teacher practice when teachers strive to align with the standards. Video recorded instruction of eight climate change-anchored lessons spanning three consecutive years were thematically coded. Results indicate that the problematic aspects of the NGSS’s characterization of climate change can help explain the framing of environmental issues and the compartmentalization of humans relative to the climate science in teachers’ lesson plans and instruction. The NGSS promulgate disconnected agency which appears in teacher and student talk in classrooms. Our analysis reveals opportunities to use standards to design interventions for classroom practice to support diverse students in countering the assumptions about the human-environment relationship embodied in the NGSS.  相似文献

This study measured aspects of the couple relationship to examine direct and indirect relations with parental involvement in education and children's school outcomes. The sample (n = 100) consisted of families that have at least one child between the ages of 8 and 11 in urban central Taiwan. Findings indicated that couple relationship quality is related to parent involvement and parent involvement is related to child school outcomes. Aspects of the couple relationship were also related to children's negative attitudes toward school. Path analyses showed a direct path from dyadic consensus to school success and an indirect path from coparenting strategy use to child school success through parental involvement in education. Bootstrap analyses confirmed the reliability of the models.  相似文献

This paper reports the results of an 18-month integrated, problem-solving research study of one new school’s efforts to create a K-12 system of student assessment data that reflects their innovative vision for personalized and student-centered instruction. Based on interview, observational, and documentary data, the authors report how teachers articulate, measure, and assess student core competencies, aligned with a common vision and supported by a technology interface designed to promote data use. Findings from this study add to the research literature on assessment and data use by articulating the necessary knowledge and supports teachers in new autonomous schools need to develop and formatively use student assessment data.  相似文献
