This paper explores experiences that remained salient in the memories of former participants in three nature-based programs in Colorado, five to forty years after childhood involvement. Interviews with program founders and staff, archival research, and observations of current activities provided an understanding of each program’s history, mission and educational approach. In this context, 18 former participants were interviewed about program experiences that they remembered and program impacts on their environmental identities and academic or career choices. Results were analyzed through the lens of social practice theory, which has significant implications for the design and evaluation of environmental education programs. Results showed that social practice theory is a useful framework for interpreting the development of a social environmental identity, but an ecological identity that forms through direct contact with the natural world is an important complementary concept.  相似文献

This study explores the impact of one-to-one computing on student achievement in Ohio high schools as measured by performance on the Ohio Graduation Test (OGT). The sample included 24 treatment schools that were individually paired with a similar control school. An interrupted time series methodology was deployed to examine OGT data over a period of 5 to 8 years. Overall student performance and content-specific achievement in math, reading, science, social studies, and writing were not significantly affected by the introduction of 1:1 computing. Treatment schools using a netbook device produced the greatest overall change in scores.  相似文献

As institutions of Higher Education try to balance limited resources with the rising costs of technology, some institutions are turning to Open Source software for campus-wide applications such as course management systems and portals. The assumption is that Open Source will provide the flexibility to build pedagogically sound learning environments while increasing technology efficiencies. This paper outlines the current state of Open Source software deployment in US Higher Education based on a survey of 772 Chief Academic Officers and Chief Information Officers conducted in 2006. The results indicate that Carnegie classification is a critical differentiator of awareness, adoption, and perceptions of Open Source software applications, with perceived cost of ownership being the key driver of Open Source adoption. Moreover, the study shows that institutions have made little progress in the development of polices and procedures for Open Source regulatory compliance and security. The study serves as a baseline for future research into the conditions for successful use of Open Source for supporting integrated learning environments that deliver campus-wide efficiencies.

Phonological awareness, phonological memory, and phonological access to lexical storage play important roles in acquiring literacy. We examined the convergent, discriminant, and predictive validity of these phonological processing abilities (PPA) in 389 3-, 4-, and 5-year-old children. Confirmatory factor analysis supported the validity of each PPA as separate from general cognitive ability and separate from each other. Multigroup structural equation modeling (SEM) with mean structure demonstrated that older preschoolers have better developed latent PPA than younger preschoolers but that the structure of PPA is equivalent. RAN was found uniquely associated with letter knowledge and text discrimination in younger preschoolers, and PA was found uniquely associated with word reading skills in older preschoolers. Finally, general cognitive ability was only indirectly associated with emergent literacy via PPA. These results highlight the importance of PPA in the early literacy development of English-speaking preschool children.  相似文献

Test anxiety among academically talented high school students (N = 103) was explored in this study. Two components of test anxiety were assessed: a cognitive component (worry) and a physiological component (emotionality). The results indicated that these students suffered from test anxiety, and that higher anxiety was related to lower science performance. Overall, females reported more test anxiety than did males. Whereas females experienced higher worry than emotionality, males reported little difference between the two anxiety components. Implications for college-bound students are discussed. © 1996 John Wiley & Sons, Inc.  相似文献

This study investigated the relative merits of using teacher judgment and the Slosson Full-Range Intelligence Test to estimate the math and reading achievement of students in a summer remedial-reading program. The subjects included children in grades kindergarten through six who were enrolled in the Auburn University Summer Clinic. Components analyses showed that the Slosson Full-Range Intelligence Test recovered substantially more variance from the distributions of the KeyMath-Revised and the Woodcock Reading Mastery Tests-Revised than did teacher judgments. Analysis of variance showed that significant differences between the means of the three tests resulted from the inclusion of students with learning disabilities. Implications of the results are discussed.  相似文献
