This paper posits that social networking can take a central role in learning in informal environments such as museums, libraries and galleries. It argues that social media offers young people agency previously unavailable in informal learning environments in order to explore complex responses to and participation with cultural content. The paper will consider transformations in digital literacy and the processes by which young learners can connect with knowledge in informal learning environments to become active cultural participants. Die Wirkung sozialer Medien auf informelle Bildung in Museen Dieses Papier postuliert, dass soziale Vernetzung eine zentrale Rolle im Lernen in informellen Umgebungen wie Museen, Bibliotheken und Galerien annehmen kann. Es behauptet, dass soziale Medien jungen Leuten als Agentur in informellen Lernumgebungen dienen können, die zuvor nicht verfügbar sind, um komplexe Antworten zu erkunden und Beteiligung mit kulturellem Inhalt zu erkennen. Die Autoren betrachten Transformationen in digitalen Fähigkeiten und den Prozessen, durch die junge Anfänger sich mit Wissen in anderen informellen Bildungsumgebungen verbinden können, um aktive kulturelle Teilnehmer zu werden. L’impact des medias “sociaux” sur l’apprentissage informel dans les musées Le présent article affirme que la mise en réseau humain peut jouer un rôle central pour l’apprentissage dans des environnements informels comme les musées,les bibliothèques et les galeries. Il avance que les medias “sociaux” offrent aux jeunes des moyens qui n’existaient pas auparavant dans les environnemetns d’apprentissage informels pour permettre d’explorer des réactions complexes et d’interagir avec le contexte culturel. Les auteurs examinent les mutations de la compétence numérique et les processus par lesquels les jeunes apprenants peuvent se brancher sur la connaissance dans des environnements d’apprentissage informels pour devenir des acteurs culturels dynamiques. El impacto de los medios colectivos sobre el aprendizaje informal en los museos Esta artículo postula que la creación de redes humanas puede desempeñar un papel central para el aprendizaje en entornos informales como los museos, las bibliotecas y las galerías. Apunta que los medios sociales ofrecen a los jovenes capacidades que antes no estaban asequibles dentro de los entornos de aprendizaje informal para explorar las respuestas complejas y interagir con el contexto cultural. Los autores consideran las transformaciones en el alfabetismo digital y los procesos a través de los cuales los jovenes alumnos pueden conectarse con los conocimientos dentro de esos entornos informales de aprendizaje para convertirse en actores culturales dinámicos. 相似文献

Children in day care and early childhood programs are becoming more at-risk in the development of appropriate self-esteem. This is evidenced by a number of inappropriate practices in some programs. These practices include a heavy emphasis on testing, homogeneous grouping, the use of a large number of worksheets, heavy drill, and long periods of sitting and listening (Manning & Manning, 1981). Teachers and day care providers can have a great impact on a child's self-esteem. This article is concerned with helping teachers by answering the following questions: What is self-esteem? What are the requirements for high self-esteem? What can a teacher do to encourage appropriate self-esteem? 相似文献

In motor skill performance and retention the complexity of knowledge of results should interact with the child's processing rate. This rate has been demonstrated to increase with age. Two experiments were designed to assess this hypothesis. In Experiment 1, 30 7-year-old and 30 10-year-old boys were randomly assigned within age level to three knowledge of results (KR) conditions: no KR, general KR, and precise KR. Performance was assessed on a vertical positioning task at two angles, 60° and 100°, for 10 performance trials. The preciseness of KR interacted with age and the degree of the angle, indicating that at the more difficult angle (60°) preciseness may have been detrimental to the performance of the 7-year-olds but beneficial to the 10-year-olds. At the easier angle (100°), precise KR improved performance for both age groups. In Experiment 2, 27 second-grade and 27 fourth-grade children were randomly assigned within age groups to the same three levels of KR preciseness. A horizontal curvilinear positioning task was used as the motor task and subjects were given 40 acquisition and 19 KR withdrawal trials. Results suggested that while KR was better than no KR during learning, the level of KR preciseness was of minor importance. However, the preciseness of KR during acquisition was of considerable value after KR was withdrawn (retention phase). The older children were able to use more precise KR to form a perceptual trace more resistant to forgetting, while the younger children were unable to use the additional information contained in precise KR. 相似文献

Abstract The developmental nature of reaction time (RT) and anticipation timing (AT) performance, as well as the relationship between them, was investigated using 15 male and 15 female subjects at each of five age levels—7, 9, 11, 13, and 20 yrs. Each subject was given 40 trials for both RT and AT performance with task order counterbalanced. Results indicated that as age increased RT decreased, with males having more rapid RT than females. The two younger age groups differed from the three older groups on AT performance. RT was significantly correlated with AT (|CE| measure) for the 7, 9, and 11 yr old males but not in any other age by gender condition. Apparently neither young males nor young females have a good motor plan in memory to control AT performance. However, the more rapid RT (and thus better response initiation) of the males allows better AT performance at the younger ages. Beginning about 10–11 yrs of age, better motor plans are developed in children's memory system, leading to less reliance on rapid RT for good AT performance, and thus the correlation between RT and AT performance is not present. 相似文献

Abstract This study evaluated the influence of biological and environmental variables on the differences between the throwing performance of 5-year-old girls and boys. A total of 100 children (48 girls, 52 boys) were tested on throwing for distance and rated on two components of throwing form—trunk rotation, and foot action. Children were evaluated on eight biological characteristics—height, weight, body mass index, ponderal index, sum of four skinfolds, body diameters, arm and leg girths, and somatotypes—and four environmental characteristics—older brother, older sister, presence of adult male, and playing with older children. Results indicated that boys threw farther than girls and exhibited more mature form. Boys had greater joint diameters than girls, a smaller sum of four skinfolds, and more estimated arm muscle. Boys were more likely to play regularly with older children. Girls' throwing performance was only 57% that of boys, but when throwing was adjusted for a linear composite of biological variables, girls' throwing performance increased to 69% of boys'. Thus, while the differences in most motor performance tasks between boys and girls prior to puberty have been attributed to environmental factors, some of the differences in throwing performance appears to reflect biological characteristics, even as early as 5 years of age. 相似文献

Abstract Meta-analysis is a set of procedures used to quantify, integrate, and analyze the findings of a large number of research studies. It offers the advantage of quantifying effects from individual studies in addition to specifying the procedures the authors followed when reviewing the literature. Although meta-analysis has been demonstrated as a useful technique in exercise and sport research, and new and more appropriate statistical techniques for use in meta-analysis have been developed, these procedures are not widely used. This tutorial describes these advances and provides an example of their application to data from gender differences in throwing velocity during childhood and adolescence. 相似文献

This paper reports on a 16-week sport education (SE) unit with just over 70 year 5 students (M age = 10.04 years) in one United Kingdom school during the spring and summer terms and discusses students' SE experiences. Student interviews were conducted throughout the season and a questionnaire on different motivation aspects was administered prior to and before completing the SE season. We report and examine the data in relation to hypothesized influences on fun and enjoyment, including being part of a team, autonomy, and improving game play. The principal reasons SE may be more enjoyable than previous physical education lessons include the greater opportunities for autonomy, affiliation, and competition, plus perceived learning. 相似文献

The purpose of this study was to develop an instrument measuring teacher communication concern as experienced by graduate teaching assistants (GTAs). Two‐hundred and thirty‐three GTAs enrolled in a preservice orientation program completed two scales: a revised, expanded version of the Teacher Communication Concern scale and a 28‐item Concerns Checklist. Results indicate that GTAs experience eight somewhat interrelated types of concern: self, task, impact, role conflict, teaching, area knowledge, procedural knowledge, and time management. Furthermore, GTA variables of expected duties, prior teaching experience, newness to area, foreign born, and age are likely to predict differential types of concerns. 相似文献

Undergraduates commonly harbor alternate conceptions about evolutionary biology; these alternate conceptions often persist, even after intensive instruction, and may influence acceptance of evolution. We interviewed undergraduates to explore their alternate conceptions about macroevolutionary patterns and designed a 2-h lesson plan to present evidence that life has evolved. We identified three alternate conceptions during our interviews: that newly derived traits would be more widespread in extant species than would be ancestral traits, that evolution proceeds solely by anagenesis, and that lineages must become more complex over time. We also attempted to measure changes in the alternate conceptions and levels of acceptance of evolutionary theory in biology majors and nonmajors after exposure to the lesson plan. The instrument used to assess understanding had flaws, but our results are suggestive of mixed effects: we found a reduction in the first alternate conception, no change in the second, and reinforcement of the third. We found a small, but significant, increase in undergraduate acceptance of evolutionary theory in two trials of the lesson plan (Cohen's d effect sizes of 0.51 and 0.19). These mixed results offer guidance on how to improve the lesson and show the potential of instructional approaches for influencing acceptance of evolution. 相似文献
