Viewing Michigan’s digital future: results of a survey of educators’ use of digital video in the USA 总被引:1,自引:1,他引:0

Digital video is a growing and important presence in student learning. This paper reports the results of a survey of American educators in Michigan (n = 426) conducted in spring 2008. The survey included questions about educators’ attitudes toward the streaming and downloadable video services available to them in their schools. The survey results showed that educators mainly used digital video to introduce and to conclude learning experiences. These educators, who predominantly used the Web‐based unitedstreaming TM digital video service, relished the service’s content breadth, short clips and potential to foster instructional innovation. However, many survey respondents reported concerns about internet connection bandwidth, projection capabilities and lack of end‐user control over on‐demand download and manipulation. Educators viewed school‐level Information and Communications Technology policies, bandwidth capacity and lack of support personnel as the causes of these difficulties. Because little research has been done on the implementation of digital video services in US schools, the conclusions of this study may provide direction for educators, researchers and policy‐makers who use a variety of digital video platforms and services. 相似文献

Wild botanic gardens consist of natural or semi-natural land remnants immersed in large urban areas or botanic gardens, which are managed for purposes of biodiversity preservation and public recreation. In Latin America, they tend to be affected by budget limitations; however, they serve as valuable resources that permit the development of innovative environmental education programmes. Specifically, we are considering the appropriateness of implementing critical environmental education and socio-constructivist programmes. As for practical considerations, it is important to include diverse epistemologies, and therefore, strategies or procedures characteristic of science teaching, such as problem-based learning, together with other characteristics of social activism and popular education initiatives, such as assemblies or meetings, and others characteristic of more traditional and indigenous worldviews, such as celebrations of the earth. In this way, Latin American wild botanic gardens may play a role in constructing environmentally responsible societies and the nurturing of a culture of reflective inquiry. 相似文献

Pigeons and adult humans searched for a 2-cm2 unmarked goal in digitized images of an outdoor scene presented on a touch-screen monitor. In Experiment 1, the scene contained three landmarks near the goal and a visually rich background. Six training images presented the scene from different viewing directions and distances. Subsequent unreinforced tests in which landmark or background cues were removed or shifted revealed that pigeons’ search was controlled by both proximal landmarks and background cues, whereas humans relied only on the proximal landmarks. Pigeons’ search accuracy dropped substantially when they were presented with novel views of the same scene, whereas humans showed perfect transfer to novel views. In Experiment 2, pigeons with previous outdoor experience and humans were trained with 28 views of an outdoor scene. Both pigeons and humans transferred well to novel views of the scene. This positive transfer suggests that, under some conditions, pigeons, like humans, may encode the three-dimensional spatial information in images of a scene. 相似文献

“Mainstreaming” legislation requires that special needs students participate in regular classroom activities to the extent possible. Studies indicate, however, that, neither parents, peers, nor professionals may be expected to hold positive attitudes toward these students or be competent providers of positive growth experiences. Existing evidence supports the need for comprehensive training programs for these groups which provide an interface between their experiences with special needs students and an introduction to new knowledge. School psychologists should assume a leadership role in development and implementation. 相似文献

Most LD students spend the major part of the school day within the regular classroom. Research, however, supports the rejected status of these students. The purpose of this presentation is to: (a) review research pertaining to the feelings professionals and peers have about learning disabled students, and (b) review those factors that may be important for consideration when attempting to modify these perceptions. School psychologists should address the attitudinal issues with a knowledge and basic conceptualization of various strategies that may be utilized to initiate attitude modification programs. 相似文献

The discourse around students from low socio-economic backgrounds often adopts a deficit conception in which these students are seen as a ‘problem’ in higher education. In light of recent figures pointing to an increase in the number and proportion of these students participating in higher education [Pitman, T. 2014. “More Students in Higher ed, But it's no more Representative.” The Conversation 28: 1–4] and an absence of evidence to support deficit thinking, this deficit discourse requires re-examination. Qualitative data from 115 interviews carried out across 6 Australian universities as part of a national study reveal that, contrary to the conception of these students as a ‘problem’, students from low SES backgrounds demonstrate high levels of determination and academic skills and that they actively seek high standards in their studies. This paper critically examines deficit conceptions of these students, drawing on findings from qualitative interviews with 89 successful students from low SES backgrounds and 26 staff members recognised as exemplary in their provision of teaching and support of students from low SES backgrounds. Drawing on these findings, this paper challenges the deficit discourse and argues for a more affirmative and nuanced conception of students from low SES backgrounds. 相似文献
