The impact of an experimental, one-semester suspension of mathematics and English prerequisites from 12 courses is investigated. Data on enrollment, student performance, and instructor opinions are analyzed for the total group, and results concerning English versus mathematics prerequisites are compared. Implications for further research on the…

In this paper we present a history of the idea of Open Educational Resources, overview the current state of the Open Educational Resources movement, report on critical issues facing the field in the immediate future, and present two new projects to watch in 2009.

Recruiting, preparing, and retaining high quality secondary mathematics and science teachers are three of the most critical problems in the nation's urban schools that serve a vast majority of children from socially and economically disadvantaged backgrounds. Although the factors contributing to these problems are complex, one area that has caught…

Over the period 2006-2008, the Dutch Open Universiteit Nederland conducted an experiment in which Open Educational Resources (OER) were offered in an effort to bridge the gap between informal and formal learning and to establish a new style of entry portal to higher education with no barriers at all. OpenER received considerable attention both in…

The paper discussed the difficulties and problems in experimental researches in educational technology, such as misunderstanding in teachers' concept, disjointedness between theory and practice, inadequate understanding of dialectics in experimental educational technology researches, research project selection and theoretical hypothesis formation…

J. S. Joseph, M. M. Chun, and K. Nakayama (1997) found that pop-out visual search was impaired as a function of intertarget lag in an attentional blink (AB) paradigm in which the 1st target was a letter and the 2nd target was a search display. In 4 experiments, the present authors tested the implication that search efficiency should be similarly…

Two experiments were conducted to examine whether abrupt onsets are capable of reflexively capturing attention when they occur outside the current focus of spatial attention, as would be expected if exogenous orienting operates in a truly automatic fashion. The authors established a highly focused attentional state by means of the central…

Champaign Park District in Illinois initiated a test run of an experimental summer playground program called the "Adventure Playground." (Editors/JA)

This experimental study assessed the effectiveness of fundraising messages. Based on recent findings regarding the effects of message framing and evidence, effective fundraising messages should combine abstract, statistical information with a negative message frame and anecdotal evidence with a positive message frame. In addition, building on…

This article offers guidelines for the development of adventure parks drawn from experience with the Champaign Park District's project. (JA)

One must be extremely careful about reaching decisions concerning the state of a child's cognitive development on the basis of the results of tests that are highly unreliable in their present form. (CK)
