Improving Biology Performance with Workshop Groups 总被引：1，自引：1，他引：1

This 2-year quasi-experiment evaluated the effect of peer-led workshop groups on performance of minority and majority undergraduate biology students. The workshop intervention used was modeled after a program pioneered by Treisman (1992). Majority volunteers randomly assigned to workshops (n = 61) performed significantly better than those assigned to the control group (n = 60, p < 0.05) without spending more time studying. Workshop minority students (n = 25) showed a pattern of increasing exam performance in comparison to historic control minority students (n = 21), who showed a decreasing pattern (p < 0.05). Volunteers (n = 121) initially reported that biology was more interesting and more important to their futures than to nonvolunteers' (n = 435, p < 0.05). Volunteers also reported higher levels of anxiety related to class performance (p < 0.05). The relationship of anxiety to performance was moderated by volunteer status. Performance of volunteers was negatively associated with self-reported anxiety (r = –0.41, p < 0.01). Performance of nonvolunteers was unrelated to self-reported anxiety (r = –0.02). Results suggest elevated anxiety related to class performance may increase willingness to participate in activities such as workshop interventions. In addition, students who volunteer for interventions such as workshops may be at increased risk of performance decrements associated with anxiety. Even so, workshop programs appear to be an effective way to promote excellence among both majority and minority students who volunteer to participate, despite the increased risk of underperformance associated with higher levels of anxiety. 相似文献

Comprehension monitoring in preschool children 总被引：1，自引：0，他引：1
This study examined the ability of 2 1/2-4 1/2-years-olds to recognize comprehension difficulties and to implement strategies for resolving them. In the course of a play interaction, an adult female experimenter made a series of requests, some of which were designed to be difficult for the child to understand or to execute. Children's responses to these requests were compared with their responses to control requests that were easy to comprehend and comply with 3-year-olds exhibited appropriate and selective monitoring responses for some kinds of problems but not others, while 4-year-olds displayed discriminative monitoring for all types of problems presented. In contrast to previous experimental findings, these results indicate that young children are capable of detecting a variety of comprehension problems and possess appropriate strategies for resolving these difficulties with a partner in communication. 相似文献

This article presents a model for integrating research into the software design process, based on the experience of the Interactive Technologies Division of the Children's Television Workshop. The model has three components: (a) using existing research literature to inform initial design decisions and suggest possible issues to be tested during the development of prototype products, (b) conducting in-house basic research studies to provide information unavailable in the published literature, and (c) conducting formative research studies on products in development to assess their usability and to ensure their effectiveness as learning tools. Issues in interpreting published studies are considered, and insights from the results of basic and formative studies conducted by the Interactive Technologies Division are also reviewed.He attended Cornell and received his Ph.D. from Rutgers University in developmental psychology and research design in 1988.She holds a Ph.D. in developmental psychology from the University of Michigan and has been researching and producing software at CTW for seven years. 相似文献

This study evaluated young children's understanding of and ability to use an input device of the type associated with home-entertainment systems (like videogame players, DVD's, and other interactive systems that connect to a television set). These systems have the potential to serve as a powerful platform for delivering interactive educational programming to young children. However, the input controllers for these systems have proven extremely difficult for young children to use, as they typically require use of very small buttons that are close together, and arrow-based keys or joystick-like devices. To examine the potential for enabling young children to use such hardware devices, three adapted software interfaces were implemented. Eighty-four children, ranging in age from 36 to 59 months and from lower to lower-middle socio-economic status, participated in this study, using one of the three software interfaces to make simple on-screen choices. The results demonstrate that it is possible to enable preschool children to use home-entertainment system control devices, by implementing adapted software interfaces which limit the kinds of inputs and choices that are required. In addition, this study describes and documents a process for conducting usability research with young children using home-entertainment interactive media systems. 相似文献

A genuine interest in science is an important part of scientific literacy, and thus a critical goal for science education. Recent studies, however, have found that school science has not been effective in meeting this goal, an important reason for which is the lack of knowledge about what makes science interesting (or not) to the students. Using instructional episodes as the unit of analysis, this study investigated the effects of learning environment elements (content topic, activity, and learning goal) on student interest in science. The findings indicated that when judging the interestingness of an instructional episode, students focused primarily on the form of activity rather than content topic and learning goal. Activities that were “hands‐on” in nature and allowed for engagement with technology elicited higher interest. This study highlights the need to place more emphasis on the role of activity in constructing interesting learning environments, and in the mean time, suggests that student science interest could be improved by making changes to relatively easy‐to‐manipulate aspects of learning environments, such as those examined in the study. © 2012 Wiley Periodicals, Inc.
