With the recent adoption of the Common Core standards in many states, there is a need for quality information about textbook alignment to standards. While there are many existing content analysis procedures, these generally have little, if any, validity or reliability evidence. One exception is the Surveys of Enacted Curriculum (SEC), which has been widely used to analyze the alignment among standards, assessments, and teachers’ instruction. However, the SEC can be time‐consuming and expensive when used for this purpose. This study extends the SEC to the analysis of entire mathematics textbooks and investigates whether the results of SEC alignment analyses are affected if the content analysis procedure is simplified. The results indicate that analyzing only every fifth item produces nearly identical alignment results with no effect on the reliability of content analyses.  相似文献

The purpose of the university should be grounded in the concept of citizenship rather than the promise of increased future earnings and research consultancy work. However, this conception of citizenship should be republican rather than liberal. British higher education institutions have suffered at the hands of mechanisms intended to promote accountability. The concept of accountability has undermined the legitimate authority of the university. As pressures from student fee increases, fiscal austerity and accountability mechanisms further undermine the ethic of scholarship, the idea of the university needs to recover its central purpose to ward off civic privatism.  相似文献

This article reports research on cross-national co-operation through Information and Communications Technology (ICT) within the statutory curricula of Northern Ireland and the Republic of Ireland. Using quantitative and qualitative methods, the views and experiences of teachers in partner schools in the north and south of Ireland were sought on the capacity and potential of asynchronous computer conferencing and videoconferencing to generate collaborative work in a cross-border setting, to promote cultural awareness among primary and post-primary pupils, and to improve teacher and pupil competence in ICT. The results showed a significant improvement in ICT competence, and also revealed that technical training, enthusiasm and commitment were the key factors for success, and that not only did the pupils develop an awareness of the cultural identity of distant peers, but their sense of responsibility, self-esteem and motivation grew. This particularly helped less able and quieter pupils. There was unexpected rôle reversal when children helped their teachers within an ICT context, a situation not found elsewhere in the curriculum. Additionally, there were beneficial effects on literacy, group work and independent learning, and the skills acquired were transferable. The commitment of the teachers to continue this cross-national work with limited support is a measure of its potential sustainability.  相似文献

The present study examines how language use (e.g., personalized vs. depersonalized language) and modality (e.g., tweets vs. Facebook status updates) influence source credibility interdependently. A total of 257 participants read personalized or depersonalized health messages embedded in mock-up tweets or Facebook status updates. The results show that users perceive depersonalized tweets as more credible than depersonalized status updates posted on Facebook. On the other hand, personalized status updates on Facebook generate higher credibility judgments than personalized tweets. The findings are discussed in light of the MAIN model as well as the preconceived user expectations and communication norms of social media.  相似文献

The purpose of this study was to examine the mediating effect of resistance training skill competency on percentage of body fat, muscular fitness and physical activity among a sample of adolescent boys participating in a school-based obesity prevention intervention. Participants were 361 adolescent boys taking part in the Active Teen Leaders Avoiding Screen-time (ATLAS) cluster randomised controlled trial: a school-based program targeting the health behaviours of economically disadvantaged adolescent males considered “at-risk” of obesity. Body fat percentage (bioelectrical impedance), muscular fitness (hand grip dynamometry and push-ups), physical activity (accelerometry) and resistance training skill competency were assessed at baseline and post-intervention (i.e., 8 months). Three separate multi-level mediation models were analysed to investigate the potential mediating effects of resistance training skill competency on each of the study outcomes using a product-of-coefficients test. Analyses followed the intention-to-treat principle. The intervention had a significant impact on the resistance training skill competency of the boys, and improvements in skill competency significantly mediated the effect of the intervention on percentage of body fat and the combined muscular fitness score. No significant mediated effects were found for physical activity. Improving resistance training skill competency may be an effective strategy for achieving improvements in body composition and muscular fitness in adolescent boys.  相似文献

The development of a comprehensive protocol for quantifying soccer-specific skill could markedly improve both talent identification and development. Surprisingly, most protocols for talent identification in soccer still focus on the more generic athletic attributes of team sports, such as speed, strength, agility and endurance, rather than on a player’s technical skills. We used a multivariate methodology borrowed from evolutionary analyses of adaptation to develop our quantitative assessment of individual soccer-specific skill. We tested the performance of 40 individual academy-level players in eight different soccer-specific tasks across an age range of 13–18 years old. We first quantified the repeatability of each skill performance then explored the effects of age on soccer-specific skill, correlations between each of the pairs of skill tasks independent of age, and finally developed an individual metric of overall skill performance that could be easily used by coaches. All of our measured traits were highly repeatable when assessed over a short period and we found that an individual’s overall skill – as well as their performance in their best task – was strongly positively correlated with age. Most importantly, our study established a simple but comprehensive methodology for assessing skill performance in soccer players, thus allowing coaches to rapidly assess the relative abilities of their players, identify promising youths and work on eliminating skill deficits in players.  相似文献

As state tests of student achievement are used for an increasingly wide array of high- and low-stakes purposes, evaluating their instructional sensitivity is essential. This article uses data from the Bill and Melinda Gates Foundation's Measures of Effective Project to examine the instructional sensitivity of 4 states' mathematics and English language arts assessments to 5 measures of pedagogical quality. The results indicate modest overall levels of sensitivity, with some state assessments insensitive to most or all measures of pedagogical quality. Furthermore, there are sometimes substantial differences across states in the sensitivity of their assessments. The article calls for more research on what makes state tests instructionally sensitive and cautions against the use of insensitive assessments for consequential decisions.  相似文献

Christian higher education is charged with the distinct mission of integrating faith and learning, and course-based service-learning has been identified as a supportive platform for this undertaking. Christian service-learning represents "a teaching and learning strategy that integrates academic instruction, community service, and guided reflection from a Christ-centered, faith-based perspective in order to enhance student learning, to foster civic responsibility, and to develop servant leaders” (Mullen, 2010 Mullen, S. (2010). Integrating a service and learning paradigm in a Christian education environment. Christian Education Journal, 7(1), 162171.[Crossref] [Google Scholar], p. 164). A large volume of literature pertaining to the theoretical and practical aspects of service-learning courses exists; however, the current literature and corresponding perceptions of best practice may not fully support the distinct nature of service-learning in Christian higher education. Therefore, the purpose of this article is to examine a predominant service-learning typology that dichotomizes traditional and critical service-learning (Mitchell, 2008 Mitchell, T. D. (2008). Traditional vs. critical service-learning: Engaging the literature to differentiate two models. Michigan Journal of Community Service Learning, 14(2), 5065. [Google Scholar]) through the contextualization of faith-based higher education. Then, in an attempt to further elaborate upon Mullen’s (2010 Mullen, S. (2010). Integrating a service and learning paradigm in a Christian education environment. Christian Education Journal, 7(1), 162171.[Crossref] [Google Scholar]) definition, Morton’s (1995 Morton, K. (1995). The irony of service: Charity, project, and social change in service learning. Michigan Journal of Community Service Learning, 2(1), 1932. [Google Scholar]) typology is recommended to frame Christian service-learning as it acknowledges the validity of multiple paradigms of service-learning (charity, project, and social change) and emphasizes the manner of their implementation (thick versus thin). Micro- and macro-level strategies, based on Morton’s (1995 Morton, K. (1995). The irony of service: Charity, project, and social change in service learning. Michigan Journal of Community Service Learning, 2(1), 1932. [Google Scholar]) typology and subsequent recommendations, are provided to support faculty members and administrators attempting to implement and sustain service-learning at faith-based institutions. Specifically, Christian institutions should prioritize faith-based organizations as core partners, and faculty members should intentionally utilize reflection to integrate faith and learning.  相似文献
