Predictive Validity And Classification Accuracy Of Actigraph Energy Expenditure Equations And Cut-Points In Young Children, Xanne Janssen, Dylan P. Cliff, John J. Reilly, Trina Hinkley, Rachel A. Jones, Marijka Batterham, Ulf Ekelund, Soren Brage, Anthony D. Okely
Dr Marijka Batterham
Objectives Evaluate the predictive validity of ActiGraph energy expenditure equations and the classification accuracy of physical activity intensity cut-points in preschoolers. Methods Forty children aged 4–6 years (5.3±1.0 years) completed a ~150-min room calorimeter protocol involving age-appropriate sedentary, light and moderate-to vigorous-intensity physical activities. Children wore an ActiGraph GT3X on the right mid-axillary line of the hip. Energy expenditure measured by room calorimetry and physical activity intensity classified using direct observation were the criterion methods. Energy expenditure was predicted using Pate and Puyau equations. Physical activity intensity was classified using Evenson, Sirard, Van Cauwenberghe, Pate, Puyau, and Reilly, ActiGraph cut-points. …

Can We Identify Guessing In Student Response Patterns? A Preliminary Analysis Of A Field Trial Design, Chris Freeman
Chris Freeman
This research is grounded in the intersecting theoretical frameworks of validity of assessments (Messick, 1989), and the use of Item Response Theory (IRT) to analyse and report student achievement tests. The research questions seek to investigate the use of data from those assessments and in particular cases where guessing is an acknowledged and in some cases encouraged in student response strategies in multiple choice tests.

Do Zoos And Aquariums Promote Attitude Change In Visitors? A Critical Evaluation Of The American Zoo And Aquarium Study, Lori Marino, Scott O. Lilienfeld, Randy Malamud, Nathan Nobis, Ron Broglio
Lori Marino, PhD
Modern-day zoos and aquariums market themselves as places of education and conservation. A recent study conducted by the American Zoo and Aquarium Association (AZA) (Falk et al., 2007) is being widely heralded as the first direct evidence that visits to zoos and aquariums produce long-term positive effects on people’s attitudes toward other animals. In this paper, we address whether this conclusion is warranted by analyzing the study’s methodological soundness. We conclude that Falk et al. (2007) contains at least six major threats to methodological validity that undermine the authors’ conclusions. There remains no compelling evidence for the claim that zoos …
