With continued adoption of course management systems, librarians are assuming new roles and challenges with regard to providing information resources and library services in a digital environment. For approximately five years, the Indiana University School of Medicine has employed Angel as its online teaching environment, and the Ruth Lilly Medical Library has been actively involved in the adoption of Angel. As the implementation phase was completed, a post-implementation evaluation was due. The authors conducted an evaluation of the Angel system to evaluate utilization level, content types, and library resources/services integration. This article provides the findings of the post-implementation Angel Courses Evaluation. 相似文献

Much research has focused on student views about physics concepts, with an emphasis on the identification of alternative conceptions, and how curricula and professional development may ameliorate the situation. However, there has been little work on determining the extent of, and in separating, the student and teacher/classroom level variables that may impact student physics achievement. This study examined the effect of different student and teacher/classroom level variables on student understanding of physics concepts using hierarchical linear modeling (HLM), a regression based technique. The data were collected from 68 different teachers and 3,119 students who were using a reform curriculum, Active Physics. Teachers and students completed surveys asking about their beliefs, their classes and their personal characteristics. Students also completed a physics achievement test. The data show that students of teachers who used Active Physics for a greater portion of the year scored higher on the achievement test than did students of teachers who did not use the curriculum as much. Furthermore, the data show that the achievement gap was narrowed between boys and girls and between students with different attitudes toward physics. Additionally teachers who received inservice instruction on how to implement Active Physics narrowed the gap between students with different views of their classroom involvement. © 2009 Wiley Periodicals, Inc.

On belief-desire reasoning tasks, children first pass tasks involving true belief before those involving false belief, and tasks involving positive desire before those involving negative desire. The current study examined belief-desire reasoning in participants old enough to pass all such tasks. Eighty-three 6- to 11-year-olds and 20 adult participants completed simple, computer-based tests of belief-desire reasoning, which recorded response times as well as error rates. Both measures suggested that, like young children, older children and adults find it more difficult to reason about false belief and negative desires than true beliefs and positive desires. It is argued that this developmental continuity is most consistent with either executive competence or executive performance accounts of the development of belief-desire reasoning. 相似文献

The study examined the fears and anxieties of Chinese deaf and hard of hearing children and adolescents, and the ability of parents and teachers to report the presence of these fears and anxieties. Chinese deaf youth are at risk due to a lack of trained teachers, an overemphasis on oral education in schools, negative stereotypes, and parental overprotectiveness. The deaf children and adolescents in the study reported significantly higher levels of total fears, total anxieties, fear of the unknown, fear of injury and small animals, fear of medical procedures, and concentration anxiety than their hearing counterparts. Girls reported more total fears, fear of the unknown, fear of minor injury and small animals, and fear of failure and criticism than boys. Parents showed a better ability than teachers to confirm these reports of fears and anxieties. Implications and directions for future studies are presented. 相似文献

The importance of play on a young child's development cannot be understated. Play gives children opportunities to understand the world, interact with others, express and control emotions, develop symbolic capabilities, attempt novel or challenging tasks, solve problems, and practice skills. Play may contribute to the development of posture, movement, and self-sufficiency. There also appears to be a positive relationships between the frequency and complexity of young children's play and IQ, problem-solving, creativity, language and literacy, and social competence. This paper provides a review of the literature and describes the development of a preschool play-based curriculum for children with disabilities. 相似文献

Powerful computational procedures are now available to better determine the accuracy of statistical estimates derived from data that have unknown distributions or do not meet parametric requirements. These techniques are generally called resampling plans and include the recently developed bootstrap. Science educators often face the problem of nonnormal distributions especially when conducting large-scale assessments or evaluating national curriculum projects that require complex sampling plans. Resampling techniques permit the researcher to make inferences without the strong distributional assumptions needed for more traditional parametric approaches. In this study, the bootstrap and a simplified version of a half-sample replication are used to examine the precision of science test scores obtained in a large-scale evaluation of Scope, Sequence, and Coordination, a national science curriculum project. The resampling plans are described in some detail and the results are compared with those obtained from parametric methods. © 1998 John Wiley & Sons, Inc. J Res Sci Teach 35: 697–704, 1998. 相似文献

Much effort has been devoted to the derivation of short forms of intelligence tests. The present study was undertaken to develop a short form of the WISC-R for the intellectually gifted. The results confirmed previous findings that the Vocabulary and Block Design dyad comprise the best two-subtest short form. The present study indicated that the Similarities, Vocabulary, Block Design, and Object Assembly tetrad could be the most useful in time and reliability. 相似文献
