The purpose of the Department of Physics's close association with the Gothard Observatory is to provide a foundation in basic astronomy and astrophysics during 3 semesters in Berzsenyi Daniel Teacher Training College for future Hungarian Elementary School teachers who will teach pupils to age 14 years. The courses of lectures include: Solar System, Sun, Stars, Stellar Interiors and Atmospheres, Astronomical Techniques, Extragalactic Astronomy, Cosmology. Students have outstanding opportunities to learn and to apply in their research the development of instrumentation, and the techniques of observation with telescopes. Excellent modern computing facilities for support of data analysis and theoretical work are available at Gothard Observatory. Library facilities contain a wealth of astronomical reference materials. Students have direct access to many facilities of the Department and Observatory. 相似文献

Models were developed for calculating the mechanical characteristics and the on-snow performance of snowboards.The snowboards
are constructed of layers of materials which may include wood, foam, honeycomb, fibre-reinforced composites and polymeric
materials.The models pertaining to the mechanical characteristics provide the bending and torsional stiffnesses, the flex
and the twist.A computer code (Snowboard-MECH) was written which yields numerical values for these characteristics.The model
for on-snow performance simulates the travel of a snowboarder of given height, weight and skill level, down an S-shaped course.A
second computer code (Snowboard-TURN) was written in support of this model; this calculates the time it takes the snowboarder
to complete the course.The two computer codes were verified by comparing their outputs with laboratory data and with data
generated by a snowboarder completing a prescribed S-shaped course.The results generated by the models and the data are in
agreement, lending support to the models and the corresponding computer codes.A procedure is described by which the computer
codes developed in this study can be utilized in the design of snowboards. 相似文献

Scholars of supportive communication are primarily concerned with how variations in the quality of enacted support affect individual and relational health and well-being. But who gets to determine what counts as enacted support? There is a large degree of operational heterogeneity for what gets called enacted support, but little attention has been afforded to the issue of whether these assessments are substitutable. In two studies we use self-reports, conversational partner-reports, and third-party ratings of two quintessential behavioral support indicators, namely, listening and immediacy. Using a multitrait–multimethod (MTMM) design, Study 1 found (1) little association between the enacted support assessments and (2) a high degree of common method variance. A second study found moderate-to-high degrees of effective reliability (i.e., consistency of judgments within a set of judgments, or mean judgments) for enacted support evaluations from the perspective of unacquainted and untrained third-party judges. In general, our data provide cautionary evidence that when scholars examine evaluations of enacted support, perspective matters and might ultimately contribute differently to well-being and health. 相似文献

Teachers' ratings of conflict and closeness as well as observed emotional support are known predictors of children's social functioning. Consistency in emotional support represents an emerging line of research. The goal of the present study is to understand whether the relation between the consistency of teachers' emotional support and children's behavior is mediated by teacher–child relationships. The role of gender is also considered. Using MPlus, the present study examines the indirect effect of emotional support consistency in prekindergarten on children's social competence and problem behaviors. Outcomes are extended to kindergarten to test the lasting association between the prekindergarten social environment and child behavior in the kindergarten year. Multigroup models examine gender differences. Research Findings: Observations of 694 prekindergarten classrooms revealed that teachers' emotional support consistency had an indirect effect on social competence and problem behavior through conflict in the teacher–child relationship in prekindergarten and kindergarten. The indirect effect on prekindergarten problem behaviors through conflict was stronger for boys. For closeness, all outcomes were significant with the exception of the indirect effect on problem behaviors in the kindergarten year. Practice or Policy: Consistency in prekindergarten teachers' emotional support has an indirect effect on children's behavior in prekindergarten and the following year in kindergarten through teacher–child relationships. Improving teachers' emotional support consistency may be 1 avenue for strengthening teacher–child relationships. 相似文献

There is a need for psychometrically sound measures of youth experiences of community/home leisure activity settings. The 22-item Self-Reported Experiences of Activity Settings (SEAS) captures the following experiences of youth with a Grade 3 level of language comprehension or more: Personal Growth, Psychological Engagement, Social Belonging, Meaningful Interactions, and Choice & Control. Forty-five youth aged 14–23 years (10 with severe disabilities) completed the SEAS in 160 leisure activity settings. The SEAS has good to excellent internal consistency (Cronbach’s alpha from 0.71 to 0.88) and moderate test–retest reliability (mean scale intra-class correlation coefficient = 0.68), as expected due to changes in activity settings over time. The SEAS was able to differentiate various types of activity settings and participation partners. The SEAS can be used to gain greater understanding of situation-specific experiences of youth participating in various types of recreation and leisure activity settings, including youth with different types of disabilities and those without disabilities. 相似文献

Research suggests that a large percentage of kindergarten children do not successfully transition to school (Rimm-Kaufman et al. 2000). As a result, a number of school transition initiatives have been developed by educators and policy makers to address the difficulties young children may experience upon kindergarten entry. Despite this attention, our review found no studies examining the involvement of school psychologists in kindergarten transition practices. The present study reports the outcomes of a national survey of the membership directory of the National Association of School Psychologists examining school-based involvement in kindergarten transition activities; school psychologists’ perceived involvement with and training in kindergarten transition activities; and school psychologists’ perceived barriers to engage in kindergarten transition activities. Results showed that most schools engaged in at least one kindergarten transition activity per year, with half of the responding sample reporting involvement. School psychologists were more likely to be involved in kindergarten transition activities if they were employed in an urban locale or a large to moderate-sized school setting. School psychologists most frequently reported involvement with kindergarten screenings and collaborating with kindergarten and preschool teachers. Implications and recommendations for practice among early childhood and other educational professionals are delineated. 相似文献

This article describes the development, validation and application of a Rasch-based instrument, the Elementary School Science Classroom Environment Scale (ESSCES), for measuring students’ perceptions of constructivist practices within the elementary science classroom. The instrument, designed to complement the Reformed Teaching Observation Protocol (RTOP), is conceptualised using the RTOP’s three construct domains: Lesson Design and Implementation; Content; and Classroom Culture. Data from 895 elementary students was used to develop the Rasch scale, which was assessed for item fit, invariance and dimensionality. Overall, the data conformed to the assumptions of the Rasch model. In addition, the structural relationships among the retained items of the Rasch model supported and validated the instrument for measuring the reformed science classroom environment theoretical construct. The application of the ESSCES in a research study involving fourth grade students provides evidence that educators and researchers have a reliable instrument for understanding the elementary science classroom environment through the lens of the students. 相似文献

Using an epidemiological sample (N = 1,117) and a prospective longitudinal design, this study tested the direct and indirect effects of preverbal and verbal communication (15 months to 3 years) on executive function (EF) at age 4 years. Results indicated that whereas gestures (15 months), as well as language (2 and 3 years), were correlated with later EF (φs ≥ .44), the effect was entirely mediated through later language. In contrast, language had significant direct and indirect effects on later EF. Exploratory analyses indicated that the pattern of results was comparable for low‐ and not‐low‐income families. The results were consistent with theoretical accounts of language as a precursor of EF ability, and highlighted gesture as an early indicator of EF. 相似文献
