Supplemental instruction classes have been shown in many studies to enhance performance in the supported courses and even to improve graduation rates. Generally, there has been little evidence of a differential impact on students from different ethnic/racial backgrounds. At San Francisco State University, however, supplemental instruction in the Introductory Biology I class is associated with even more dramatic gains among students from underrepresented minority populations than the gains found among their peers. These gains do not seem to be the product of better students availing themselves of supplemental instruction or other outside factors. The Introductory Biology I class consists of a team-taught lecture component, taught in a large lecture classroom, and a laboratory component where students participate in smaller lab sections. Students are expected to master an understanding of basic concepts, content, and vocabulary in biology as well as gain laboratory investigation skills and experience applying scientific methodology. In this context, supplemental instruction classes are cooperative learning environments where students participate in learning activities that complement the course material, focusing on student misconceptions and difficulties, construction of a scaffolded knowledge base, applications involving problem solving, and articulation of constructs with peers. 相似文献

This paper reviews research on students’ usage of university counselling services across countries and their demographic and
psychological characteristics. In doing so, emphasis is given to reported distinctions between local and international university
students. Utilisation rates, encouraging factors and barriers to utilisation, presenting problems, and methodological problems
with existing studies are each examined. The findings suggest that only a minority of between 2% and 4% of university students
access such services, with females being more likely to use them than males. International students in particular underutilise
these services, and this is primarily due to such students’ preference for seeking help from family or friends over outside
sources. When students do seek assistance, their presenting issues most commonly involve symptoms of depression or anxiety,
as well as academic and relationship difficulties. 相似文献

Having become fully integrated into the contemporary politicallandscape, infotainment-oriented media extend Americans’traditional news (e.g. newspaper, radio, and television) toinclude a greater number of sources for political information,and in some cases, political mobilization. Given the increasingprominence of infotainment-oriented media in contemporary politics,this study addresses the effects of one particular type of infotainment—late-nightcomedy—during the 2000 presidential campaign. Specifically,we are interested in whether watching late-night comedy showsinfluences viewers’ evaluations of the candidates whohave appeared on these shows; in particular, we investigatepriming as the mechanism by which such influences occur. Findingsfrom the 2000 National Annenberg Election Survey (N = 11,482)indicate that evaluations of candidates are based in part onrespondents’ sociodemographics, perceptions of candidatesto handle certain issues, and their character traits. Therewas a main effect of watching late-night comedy on evaluationsof candidates; more importantly, viewers were more likely thannonviewers to base their evaluations of George W. Bush on charactertraits after he appeared on The Late Show with David Letterman. 相似文献

This article summarises research carried out between 2006 and 2008 by IPTS (Institution for Prospective Technological Studies) in collaboration with a consortium of experts from 10 member states, led by ICEGEC. The project gathered information on eLearning developments to assess drivers and barriers and to suggest implications for policy and research in the 10 member states that joined the European Union in 2004. Three examples of countries (Estonia, Hungary and Slovenia) demonstrate that, while the group is not homogeneous, commonalities can be detected. Reports show that all the EU10 countries have been catching up with the older member states in ICT penetration and skills, but large digital divides remain due to regional, social and economic divides. Educational institutions are equipped with ICT, but not always at the same level in classrooms as in EU15. Universities are using ICT in education, but mostly for material provision purposes. Enterprises seem to have higher usage of eLearning solutions than in EU15, but these are not equally available for all employees. Lack of focus and coordination in policies to support eLearning developments has been assessed to be a major barrier. In general, EU10 seems to be facing similar challenges to other European countries, although specific efforts are needed to help close the divides and engage people in lifelong learning with the new opportunities ICT could provide. 相似文献

As a general and effective protection measure for copyright violations, which occur with the use of digital technologies including peer-to-peer (P2P) networks, copyright owners from the cultural sector often use Digital Rights Management (DRM) systems and digital watermarking techniques so as to encrypt copyright information to the cultural content. In other cases, copyright owners restrict or even block access to the digital cultural content through the Internet and the P2P infrastructure. This chapter claims that DRM and P2P can be quite complementary. Specifically, a P2P infrastructure is presented which allows broad digital cultural content exchange while on the same time supports copyright protection and management through watermarking technologies for digital images. 相似文献
