Teachers need knowledge and skills to make effective use of the growing variety of media and technology texts and tools available for use in elementary and secondary education. For this reason, pedagogical media competencies are highly relevant for teachers’ professional development. The theory of media pedagogical competencies is first defined and then located in the context of the relevant scholarly literature from both Germany and the United States. We conducted a comparative analysis of German and U.S. pedagogical media competency models and report data on a survey of teacher education programs in Germany and the United States to identify the proportion of programs of study that include courses in media didactics, media and school reform, and media education. We consider the implications of the missing connections between the theoretical framework of pedagogical media competencies and the current practice of media pedagogical teacher training, revealing implications for further work needed to improve the integration of media in various school-related contexts. 相似文献

We investigated various structural models of phonological processing and the relationship of phonological processing abilities to basic reading. Data were collected on 116 kindergarten and first grade students. The specific ability model, which included phonological awareness, phonological memory, and rapid automatized naming as separate abilities, had the strongest fit to the data. Of the specific phonological processing abilities, rapid automatized naming was least associated with a second-order factor. Phonological awareness and rapid automatized naming accounted for variance in word reading, although the latter demonstrated limited practical utility. Theoretical and practical implications are discussed. 相似文献

The era of technical and scientific progress ushered in with the twentieth century brought new medical knowledge such as the Halstead ‘radical’ mastectomy, which promised a cure for breast cancer. These advances in medical knowledge were premised on an epidemiological model of disease, which shaped the treatment and public understanding of breast cancer through most of the twentieth century—to be replaced by a systemic model of breast cancer in the later years of the century. This article traces how this shift was both influenced by and influential on public understandings of medicine and disease. The author argues that, while the epidemiological model of disease shaped treatment options and public health campaigns through most of the century, current treatment regimes and health campaigns are shifting to reflect changes in the underlying model of disease (toward a systemic model). 相似文献

Online focus groups may provide a new tool for research conducted in sport science settings (e.g., psychology, sociology, management, physical education, and recreation). Benefits of online focus groups include the ability for people in multiple locations to respond synchronously via chat rooms or asynchronously via discussion software. Additional benefits include increased equality of participation, greater participant diversity, the matching of research design with research environment, researcher interaction, and the elimination of transcribing. Disadvantages include under representation of non-Internet users, lack of face-to-face contact, potential participant no-show rate, and the difficulty of securing data on the Internet. Sport science scholars are encouraged to examine this emerging method as related to their specific research aims and consider application of online focus groups to further their research. 相似文献

Research Findings: Previous research has documented conflicting results on the relationship between program quality and the percentage of children receiving subsidized child care (subsidy density) in early childhood centers. This research examined the relationship between subsidy density and the quality of infant and preschool classrooms in child care centers, taking into consideration teacher education and salary as well as other structural variables associated with quality. A multimethod evaluation was conducted with 110 child care centers utilizing an interview of center directors as well as classroom observations using standardized measures of quality and language/literacy in the classroom. Regression analyses indicate that subsidy density does not predict the quality of infant classrooms. However, subsidy density is a significant predictor of the quality of preschool classrooms. Teacher education is predictive of some quality indicators, but teacher salary is not. Practice or Policy: Practice and policy implications are discussed to promote the quality of child care centers that serve low- income children. Statewide initiatives should target centers with higher subsidy density for quality improvements. Local programs and state policy should provide teachers with opportunities to obtain additional education and then offer incentives to remain in their current early childhood settings. 相似文献

Using social network data, this study examines which features of social and spatial proximity predict self‐reported, or “real,” and peer‐reported, or “inferred,” relationships among 2,695 pairwise combinations of African American second‐ through fourth‐grade students (aged 7–11). Relationships were more likely to exist, and more likely to be inferred to exist by peers, between pairs of children who were the same sex, sat near one another, shared a positive academic orientation, or shared athletic ability. Sex similarity had a dramatically larger effect on peers' inferences about relationships than on self‐reported real relationships, suggesting that children overestimate the importance of gender in their inferences about relationships. Results were stable across different grade levels in middle childhood and for boys and girls. 相似文献

The authors examined the perceptions of future school administrators regarding the role of the school counselor. The study was designed to assist counselor educators and school counselors in identifying potential barriers that could interfere with establishing comprehensive developmental counseling programs that are supervised by principals and superintendents. Future administrators rated crisis intervention, assisting with transitions, and personal counseling as the most important duties of school counselors; however, some respondents identified administrative and disciplinary duties as significant ones for the counselor. 相似文献
