Pallant, Amy; Lee, Hee-Sun; Pryputniewicz, Sara – Science Teacher, 2012
Systems thinking suggests that one can best understand a complex system by studying the interrelationships of its component parts rather than looking at the individual parts in isolation. With ongoing concern about the effects of climate change, using innovative materials to help students understand how Earth's systems connect with each other is…

Bedek, Michael; Seitlinger, Paul; Kopeinik, Simone; Albert, Dietrich – Electronic Journal of e-Learning, 2012
Digital educational games (DEGs) possess the potential of providing an appealing and intrinsically motivating learning context. Usually this potential is either taken for granted or examined through questionnaires or interviews in the course of evaluation studies. However, an "adaptive" game would increase the probability of a DEG being…

De Corte, Wilfried – Educational and Psychological Measurement, 2004
The article describes a Windows program to estimate the expected value and sampling distribution function of the adverse impact ratio for general multistage selections. The results of the program can also be used to predict the risk that a future selection decision will result in an outcome that reflects the presence of adverse impact. The method…

Dambolena, Ismael; Eriksen, Steven E.; Kopcso, David P. – PRIMUS, 2006
The logarithmic transformation is a commonly applied procedure in regression analysis when two or more variables have a nonlinear relationship. When the response variable is logarithmically transformed, confidence intervals for conditional means and predictions may actually be wider than their counterparts obtained from the model with the original…

Brandon, Richard N.; Kagan, Sharon Lynn; Joesch, Jutta M. – 2000
This policy brief describes the components of a computer model to compare different financing approaches for universal early care and education programs as developed by the Financing Universal Early Care and Education (ECE) for America's Children Project. The brief also discusses lessons learned from analyzing key features of existing…

Petrov, Alexander A.; Dosher, Barbara Anne; Lu, Zhong-Lin – Psychological Review, 2005
The mechanisms of perceptual learning are analyzed theoretically, probed in an orientation-discrimination experiment involving a novel nonstationary context manipulation, and instantiated in a detailed computational model. Two hypotheses are examined: modification of early cortical representations versus task-specific selective reweighting.…
