With the advent of the Next Generation Science Standards in engineering (NGSS, 2013), teachers of multiple subject areas are being asked to do more than ever before—not only to teach engineering content in the K-12 classroom but also to engage students in authentic disciplinary reading and writing as part of content learning. These standards sound good, but they beg several questions; namely, what do we know about how, why, and when do engineers read and write as they do their work every day? What do teachers charged with engineering education know about the daily practices of engineers, let alone the literacy practices? In short, little is known about the literacy practices of engineers in the course of their daily work. This article draws on participant observation, interviews, and document analysis of one research engineering laboratory to illustrate the literacy practices of one group of engineers and begins to draw implications from this work for teacher practice in achieving the NGSS engineering education standards.  相似文献

The Resourced Open Learning Facility (ROLF) has been developed by the UK Skills Training Agency (STA) as a means of delivering off-the-job skill training in the national network of 60 skillcentres. STA introduced ROLF as a pilot scheme in six skillcentres at a time when the government was introducing a new programme for the long-term unemployed (Employment Training). The authors evaluated the pilot scheme and concluded that ROLF was working well for low achieving adults. ROLF is also important because it is a systematic approach to open learning delivery in a chain of centres under the same management. Most educational technology literature about open learning features materials, rather than delivery.  相似文献

The current paper uses archival data to examine variations in Schwartz's and Hofstede's cultural value orientations and their relationship to attitudes toward immigration and multiculturalism reported in the Eurobarometer Survey [Attitudes towards minority groups in the European Union: a special analysis of the Eurobarometer 2000 opinion poll on behalf of the European Monitoring Centre on Racism and Xenophobia. Eurobarometer Opinion Poll. Retrieved September 1, 2003, from http://europa.eu.int/comm/public_opinion/index_en.htm] on racism and xenophobia. The results demonstrated that mastery, masculinity, power distance, uncertainty avoidance, and collectivism were associated with weaker support for policies that promote social co-existence. Masculinity and mastery were also linked to more pessimistic attitudes towards multiculturalism, and increased harmony was correlated with less desire for cultural assimilation. The results largely converge with research undertaken at the individual-level of analysis, and the data suggest four clusters of cultural values related to immigration attitudes: humanitarianism-egalitarianism, conservation, collectivism, and instrumentality.  相似文献

We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula.  相似文献

The current study examined associations between physical education (PE) class enjoyment and sociodemographic, personal, and perceived school environment factors among early adolescent girls. Participants included 1,511 sixth-grade girls who completed baseline assessments for the Trial of Activity in Adolescent Girls, with 50% indicating they enjoyed PE class a lot. Variables positively associated with PE class enjoyment included physical activity level, perceived benefits of physical activity, self-efficacy for leisure time physical activity, and perceived school climate for girls' physical activity as influenced by teachers, while body mass index was inversely associated with PE class enjoyment. After adjusting for all variables in the model, PE class enjoyment was significantly greater in Blacks than in Whites. In model testing, with mutual adjustment for all variables, self-efficacy was the strongest correlate of PE class enjoyment, followed by perceived benefits, race/ethnicity, and teachers' support for girls' physical activity, as compared to boys, at school. The overall model explained 11% of the variance in PE class enjoyment. Findings suggest that efforts to enhance girls' self-efficacy and perceived benefits and to provide a supportive PE class environment that promotes gender equality can potentially increase PE class enjoyment among young girls.  相似文献

Aging and its effects on a person's quality of life are a growing health concern and burden for many Americans. Recently, studies have shown that adopting certain healthy behaviors may help maintain and or prevent age-related health issues such as cognitive decline. However, many people are unaware of these newfound facts. Furthermore, there is insufficient research evidence to understand how older adults view brain health and the differences between diverse groups of older adults. This study examines brain health knowledge and behaviors among Caucasian and African-American community-dwelling older adults in North Carolina. Findings were significant for level of education and total brain health knowledge scores, though there were no significant differences between races. In addition, there was a significant association between total number of health conditions and total brain health knowledge scores that warrants further study.  相似文献
