Students’ confidence and perceived value for participating in cross-cultural wiki-based collaborations

An international wiki-based collaboration was integrated into a large introductory educational technology course enrolling 346 students, divided into 43 teams. Student teams participated in a 5-week project in which they created wiki chapters about the educational uses of specific Web 2.0 tools. Two to four international students, located in their home countries, participated on each team, collaborating via the evolving wiki, as well as other Web 2.0 tools. Using expectancy-value as our motivational framework, we gathered pre- and post-survey data, triangulated with focus group interview data, to examine changes in students’ confidence and perceived value for using these tools to facilitate international collaborations. Survey results showed significant changes in confidence and perceived value, while qualitative results provided insights into students’ perceptions of critical project components. We discuss students’ perceptions of project barriers as well as the strategies they implemented to achieve success.     

The Inside Story of Science City—An Outdoor Public Science Exhibition

Science City is an outdoor exhibition, supported by the National Science Foundation (NSF) and created by the New York Hall of Science (NYHS). It was designed to increase public awareness of, and interest in, the science and technology of daily life by creating a series of exhibits that people would “find” in public places in New York City. Using the streets and structures of the city to present the science and technology of everyday life in order to reach the non-museum-going public, eye-catching exhibits and signs were placed along fences, on streets and buildings and in subway stations and parks. The development and installation of museum exhibits for public urban spaces requires skills and experience that stretch beyond the expertise of a science-technology museum exhibition staff. This article discusses and compares on- and off-site exhibition development.     

Referral reasons for learning disabled students

Referral information for 269 LD students in grades one through five was examined. Referral reasons were classified according to three major types: (a) academic, (b) behavior, and (c) academic and behavior. These major referral types also were analyzed according to particular concern (e.g., reading deficits, attentional problems, etc.). The results indicated that the majority of students were referred for either academic (42%) or both academic and behavioral (41%) reasons; referrals initiated solely for behavior problems accounted for only 17% of the total. The grade level analysis revealed that academic concerns were less likely to be noted in the first and fifth grades, and that the number of referrals diminished as grade level advanced (51% of the sample was diagnosed by second grade). Referral statements within each major referral type tended to be general, as opposed to specifying particular concerns to be explored in the evaluation. Preservice and in-service training recommendations are given.
