Given that thoughtfully developed formal after-school programs can make a difference in the academic performance of schoolchildren, and that some public schools are implementing their own on-site after-school curricula, this study sought to identify programmatic features that appear to be associated with successful after-school programming. Qualitative methods were used and the study site was the Manchester Youth Development Center, which has a twenty-five-year record of effective service. The six elements found as salient were that both structure and autonomous space are provided; academic achievement is supported; the program is culturally consistent (in the present case, African-American cultural patterns are evidenced); there is a core of committed authoritative adults; the leadership is child-centered; and the environment is safe. 相似文献

The present study investigated the role of teacher-rated likeability as a mediator of the relation between low academic competence and depressive symptoms in elementary-aged children. Analyses focused on a sample of children at risk for child maltreatment living in Hawaii (n = 380). Structural equation modeling supported the hypothesized negative relations between academic competence in first grade and depressive symptoms in third grade controlling for correlated constructs (e.g., baseline social avoidance, parenting stress, externalizing problems, and internalizing symptoms). Teacher-rated likeability in second grade negatively mediated the effect of academic competence on depressive symptoms. Implications for understanding the role of early academic skill deficits and social judgments on risk for depressive symptoms as well as recommendations for interventions and prevention strategies are discussed. 相似文献

Gender equity issues remain a challenge in science, technology, engineering, and mathematics (STEM) fields, where women are highly underrepresented. As integrated STEM instruction becomes increasingly popular in elementary and middle school classrooms, it is important to consider whether the small group activities that are commonplace in STEM instruction support the equitable participation of young girls. This study builds on the existing body of literature to better understand how gender is related to student participation in small group STEM activities and whether students participate differently in science and engineering activities. A single embedded case study was used to explore the experiences of four students aged 10–11 years as they participated in small group work within an integrated STEM unit in their fifth-grade classroom. Two girls and two boys worked together throughout the unit to explore science content related to electromagnetism and apply their content knowledge to an engineering design challenge. Video and audio of students' small group interactions were analyzed using an observation protocol to code their participation in each 3-min segment of STEM activity. Student- and case-level analyses were used to identify patterns of interaction based on gender and type of activity (science vs. engineering). Findings suggest that boys and girls participate in small group STEM activities in different ways, adopting distinct roles within their group. In addition, students displayed divergent patterns of interaction in science- and engineering-focused lessons, suggesting that students need additional practice and support in navigating between science and engineering in integrated STEM units. 相似文献

Extending previous investigations by Loeb of mobilities in gaseous mixtures using his procedure except that the auxiliary field in these measurements was made equal to the advancing field thus giving absolute values of the mobilities, measurements of mobilities were made in mixtures of CH3NO2H2 and CH3CNH2. The mobilities in H2 were 7.12 for the positive ions and 10.46 for the negative ions in cm./sec. per volt/cm. Those in CH3NO2 were 0.221 cm./sec. per volt/cm. for both ions and in CH3CN they were 0.234 cm./sec. per volt/cm. for both ions. Both ion mobilities deviated from Blanc's law in CH3NO2 indicating the formation of complexes with the CH3NO2 ions somewhat greater in size than the normal ions in H2. The molecules attached to negative ions somewhat less readily than to the positive ions but both final ions were of the same size. In CH3CN mixtures both positive and negative ions deviated from Blanc's law, the positive ion showing more ready attachment of CH3CN. The negative ion had consistently a higher mobility than the positive ion, a circumstance indicating a smaller ion and suggesting that the attaching molecule might not be CH3CN but some impurity. Both ion addition products in CH3CN are larger than the normal ion in H2 but smaller than those in CH3NO2 as was to be expected. 相似文献

Background:To strengthen institutional research data management practices, the Indiana University School of Medicine (IUSM) licensed an electronic lab notebook (ELN) to improve the organization, security, and shareability of information and data generated by the school''s researchers. The Ruth Lilly Medical Library led implementation on behalf of the IUSM''s Office of Research Affairs.Case Presentation:This article describes the pilot and full-scale implementation of an ELN at IUSM. The initial pilot of the ELN in late 2018 involved fifteen research labs with access expanded in 2019 to all academic medical school constituents. The Ruth Lilly Medical Library supports researchers using the electronic lab notebook by (1) delivering trainings that cover strategies for adopting an ELN and a hands-on demo of the licensed ELN, (2) providing one-on-one consults with research labs or groups as needed, and (3) developing best practice guidance and template notebooks to assist in adoption of the ELN. The library also communicates availability of the ELN to faculty, students, and staff through presentations delivered at department meetings and write-ups in the institution''s newsletter as appropriate.Conclusion:As of August 2021, there are 829 users at IUSM. Ongoing challenges include determining what support to offer beyond the existing training, sustaining adoption of the ELN within research labs, and defining “successful” adoption at the institution level. By leading the development of this service, the library is more strongly integrated and visible in the research activities of the institution, particularly as related to information and data management. 相似文献

Parents of learning disabled, mentally retarded, and emotionally disturbed children were surveyed regarding their reactions to mainstreaming handicapped children. Results indicated that parents of learning disabled children were significantly more supportive of this educational procedure than were the other two groups of parents. Possible reasons for this difference are discussed. 相似文献

Jordan insists that teachers should be free to exercise their professionalism and that respect for difference is integral to that professionalism. For Connor, this implies teachers who can critically consider the discourses available to them as practitioners. The authors draw upon the philosophising of Gilles Deleuze to develop an account of teaching and learning as an autonomous creative process in which teachers contribute to rather than strictly control outcomes. This account of teaching as processual following resonates with Jordan's vision of equity for autistic or neuro‐atypical pupils and compassionate professionalism. It rests less easily with intensive behaviourist‐training programmes and educational cultures premised on the assumption that outcomes can, and should, be pre‐determined and precisely engineered. From a Deleuzian perspective, ethical practice is the interplay of conceptual, perceptual and affective knowledge, and it is suggested that intuitive practice involves a similar interplay along with numerous contextual considerations. A Deleuzian theory of simulation is initially outlined and accords with the emphasis placed by Jordan on reimagining an educational system in which all pupils are valued and supported to develop their varied talents and teachers are free to assess the suitability of particular methods for individual pupils. 相似文献

The current study evaluated the effectiveness of individualized math‐to‐mastery (MTM) interventions, selected though brief experimental analysis (BEA), at increasing math fluency skills for three elementary‐aged females. As MTM has only been investigated as a multicomponent intervention, the present study utilized BEA to identify those specific components that led to math skills gains in the most efficient manner possible. BEA results indicated that for two of three participants only a partial MTM intervention was necessary to prompt fluency gains, while the entire intervention was the most effective for the third. During extended analysis all three participants displayed math skills gains above those seen during repeated baseline assessments. Results are discussed in terms of further refining MTM through BEA procedures so as to individually target math skill deficits by considering both intervention effectiveness and efficiency. 相似文献
