In order to determine the potential of alternative technologies in social studies education, we must understand the goals
of such education, the capabilities of the technologies, and teachers’ and students’ responses to new technologies. The author
suggests that the new technologies can contribute to the goals of learning about the past, learning about democratic life
and institutions, and making students knowledgeable as consumers and producers of information. One major obstacle is a lack
of time and money for teachers to experiment with the technologies.
Stephen T. Kerr is professor of education in the College of Education at the University of Washington. His research focuses
on the application of new technologies in schools and other educational environments, and particularly on the ways in which
technology affects the social structure (roles and expectations, instructional patterns, organization) of those institutions.
He has done work on human-computer interaction, as well as on how new communication technologies have changed the educational
system of the former USSR. 相似文献
BackgroundDeveloping appropriate concussion prevention and management paradigms in middle school (MS) settings requires understanding parents’ general levels of concussion-related knowledge and attitudes. This study examined factors associated with concussion-symptom knowledge and care-seeking attitudes among parents of MS children (aged 10–15 years).MethodsA panel of 1224 randomly selected U.S. residents, aged ≥ 18 years and identifying as parents of MS children, completed an online questionnaire capturing parental and child characteristics. The parents’ concussion-symptom knowledge was measured using 25 questions, with possible answers being “yes”, “maybe”, and “no”. Correct answers earned 2 points, “maybe” answers earned 1 point, and incorrect answers earned 0 point (range: 0–50; higher scores = better knowledge). Concussion care-seeking attitudes were also collected using five 7-point scale items (range: 5–35; higher scores = more positive attitudes). Multivariable ordinal logistic regression models identified predictors of higher scores. Models met proportional odds assumptions. Adjusted odds ratios (aORs) with 95% confidence intervals (95%CIs) (excluding 1.00) were deemed statistically significant.ResultsMedian scores were 39 (interquartile range: 32–44) for symptom knowledge and 32 (interquartile range: 28–35) for care-seeking attitude. In multivariable models, odds of better symptom knowledge were higher in women vs. men (aOR = 2.28; 95%CI: 1.71–3.05), white/non-Hispanics vs. other racial or ethnic groups (aOR = 1.88; 95%CI: 1.42–2.49), higher parental age (10-year-increase aOR = 1.47; 95%CI: 1.26–1.71), and greater competitiveness (10%-scale-increase aOR = 1.24; 95%CI: 1.13–1.36). Odds of more positive care-seeking attitudes were higher in white/non-Hispanics vs. other racial or ethnic groups (aOR = 1.45; 95%CI: 1.06–1.99) and in older parental age (10-year-increase aOR = 1.24; 95%CI: 1.05–1.47).ConclusionCharacteristics of middle school children''s parents (e.g., sex, race or ethnicity, age) are associated with their concussion-symptom knowledge and care-seeking attitudes. Parents’ variations in concussion knowledge and attitudes warrant tailored concussion education and prevention. 相似文献
Scrummaging is a major component of Rugby Union gameplay. Successful scrummaging is dependent on the coordination of the forward players and the strength of the eight individuals. The study aim was to determine whether individual scrummaging kinetics and other candidate factors associated with scrummaging performance discriminate team scrum performances. Sixteen club-level forwards (stature: 1.80?±?0.1?m; mass: 99.0?±?18.2?kg) were initially divided into two scrummaging packs. A total of 10 various scrum permutations were tested, where players were randomly swapped between the two packs. Winning scrums were determined by two observers on opposite sides of the scrum. Fatigue (100?mm visual analogue scale (VAS)) and scrummaging effort (6–20 rating of perceived exertion (RPE)) were assessed following each scrum contest. Individual scrummaging kinetics were acquired through an instrumented scrum ergometer and muscular power indicated through vertical jump heights. Student’s t-tests were used to differentiate between winning and losing scrum packs. VAS and RPE were assessed using repeated measures ANOVAs. Winning scrum packs had significantly larger combined force magnitudes (p?<?.002), regardless of the player contribution calculations. Additionally, winning packs had less individual movement (p?=?.033) and higher combined vertical jump heights (p?<?.001) but were not significantly heavier (p?=?.759) than losing scrum packs. While perceived VAS and RPE values progressively increased (p?<?.001), no differences in the individual scrum magnitudes were observed between the 1st and 10th scrum (p?=?.418). The results indicated that the combination of individual forces, variation in movement and factors related to scrummaging performance, such as vertical jump height, were associated with team scrummaging success. 相似文献
AbstractWomen’s Artistic Gymnastics (WAG) is a sport designed specifically for women. With roots in ballet, calisthenics and eugenics, it was meant to showcase femininity, beauty, and encourage healthy bodies for motherhood, therefore offering socially acceptable sporting opportunities for females. This paper considers whether such sporting opportunities extended to female coaches. We examine the recruitment patterns in relation to gender of some of the top coaches in Australia and New Zealand since the 1980s, who are predominantly migrants. Using archival sources, interviews and personal experience, this paper argues that while so-called feminine or artistic sports can offer greater opportunities for female coaches, WAG in Australia and New Zealand remains dominated by male coaches, who have held the majority of the head coach positions and in many cases, been actively recruited from overseas. The few females who have been employed in top positions have been appointments of ‘convenience’ rather than reflective of a shift away from these gendered employment patterns. Thus, while its creation as a specifically feminine sport may lead WAG to be viewed as a site of increased opportunities for women coaches, deeper exploration reveals an unresolved tension between the use of male and female coaches. 相似文献
Various initiatives over the past 40 years have aimed to strengthen children’s early learning and social development. One policy theory—manifest in recent welfare reforms—postulates that requiring single mothers to work more outside the home will advance children’s well-being. We first examine whether young children’s social development is related to maternal employment among 405 women who entered welfare-to-work programs in 1998. For girls, age 24–42 months, we found that their mother’s recent employment duration was significantly associated with a lower incidence of aggressive behavior and inattentiveness, measured by two scales from the Child Behavior Checklist (CBCL 2/3). Yet these relationships with employment were weaker than more robust associations observed for proximal child-rearing practices, including the frequency of reading with the child, enforcing a regular bedtime, the propensity to spank the child, as well as levels of maternal depression. We then assess whether broader measures of the mother’s economic security help to predict these proximal determinants of development. We observed that food security and indicators of job quality consistently predicted the proximal factors. Structural equation models (SEM) provided additional evidence that these broader indicators of economic security, but not recent employment per se, operated through parenting practices and maternal depression to influence girls’ and boys’ social development. These results are consistent with recent findings from random-assignment experiments, showing that employment gains rarely affect child outcomes unless mothers’ income and broader economic security also improve. 相似文献
This paper reports early findings of a longitudinal research project on the experiences of beginning teachers in England. In the first phase of the study (2003–2004), data were generated via: (1) in‐depth, face to face interviews with 85 student teachers throughout England; and (2) self‐completion questionnaires, returned by 4,790 student teachers across a range of initial teacher preparation (ITP) routes. Through these methods the study set out to explore student teachers' accounts of their motivations for entering ITP, their preconceptions and expectations of teaching and ITP, and their early experiences as student teachers. A number of general themes were found to cut across all of these areas, and are presented here as core features of the experience of becoming a student teacher. These relate to the concept of teacher identity, the role of relationships, the notion of relevance, and the central presence of emotion.
Cette étude décrit les conclusions préliminaires d'une recherche continue sur les expériences de ceux qui sont en train de devenir professeurs d'école en Angleterre. En première phase de l'étude (2003–2004), les données ont été recueillies par: 1) des entretiens approfondis en tête‐à‐tête avec 85 professeurs stagiaires dans toute l'Angleterre; et 2) des questionnaires, remplis eux‐mêmes par 4,790 professeurs stagiaires sur un échantillon de préparations initiales de professeur (PIP). Avec ces méthodes l'étude avait pour but d'explorer les explications des professeurs stagiaires concernant leur motivation pour entrer dans la PIP, leurs idées reçues et leurs attentes de l'enseignement et de la PIP, ainsi que leurs expériences initiales de professeur stagiaire. On a trouvé un nombre de thèmes généraux à travers tous ces domaines, et ceux‐ci sont présentés ici comme caractéristiques fondamentales de l'expérience vécue de professeur stagiaire débutant. Ils sont relatifs aux concepts suivants : l'identité du professeur, le rôle des relations, la notion de pertinence et la présence capitale de l'émotion.
Este documento es un informe sobre los primeros resultados de un proyecto de investigación longitudinal sobre las experiencias de profesores principiantes en la Inglaterra. En la primera fase del estudio (2003–2004), los datos fueron obtenidos a partir de dos fuentes: minuciosas entrevistas cara a cara con 85 profesores en prácticas por toda Inglaterra y cuestionarios personales que fueron devueltos por 4,790 profesores en prácticas procedentes de distintas ramas de la ITP (preparación para profesores principiantes). A través de estos métodos, el estudio fue lanzado con el propósito de sondear las razones que motivaron a los profesores en prácticas a entrar en la ITP, sus preconcepciones y expectativas en cuanto a la ITP y a dar clase y sus primeras experiencias como profesores en prácticas. Estas áreas presentaron una serie de temas generales comunes que son presentados aquí como características centrales de la experiencia de convertirse en profesor en prácticas. Estas están relacionadas con el concepto de identidad del profesor, la importancia de las relaciones, la noción de relevancia, y el papel central de las emociones.
Dieses Referat berichtet über die ersten Ergebnisse eines langfristigen Forschungsprojektes, basierend auf Erfahrungen von Lehrern in England, die in den Beruf einsteigen. In der ersten Phase der Studie (2003–2004) wurden Daten gesammelt mittels: 1) ausführlicher, persönlicher Gespräche mit 85 auszubildenden Lehrern aus ganz England; und 2) selbstauszufüllender Fragebögen, die von 4,790 auszubildenden Lehrern aus verschiedenen Ausbildungsrichtungen zurückgesendet wurden. Die Studie hatte das Ziel, die Berichte der auszubildenden Lehrer zu untersuchen hinsichtlich ihrer Motivation, eine Ausbildung anzufangen, ihrer Erwartungen vom Unterrichten und von der Ausbildung, sowie ihrer ersten Erfahrungen als auszubildende Lehrer. Eine Anzahl von allgemeinen Themen wurden in allen diesen Bereichen festgestellt und sind hier als Kernmerkmale des Ausbildungsverfahrens dargestellt. Diese beziehen sich auf das Konzept der Lehreridentität, auf die Rolle von Beziehungen, auf die Idee der Relevanz, sowie auf die zentrale Präsenz von Emotionen. 相似文献
