Predictive Power of Sixth-Grade Achievement on Secondary Chemistry Academic Outcomes Florida Journal of Educational Research (2018)
The purpose of this study was to identify student level characteristics that predicted both enrollment and achievement in 10th-grade chemistry courses. We obtained a large representative sample from an academic cohort drawn from a mid-sized ...
Development of an Innovative Method for Analyzing the Presence of Environmental Sustainability Themes and an Ecological Paradigm in Science Content Standards Studies in Educational Evaluation (2014)
An iterative process for developing a method for analyzing Florida's K-12 Next Generation Sunshine State Standards science content was described. For this study, the researchers developed an innovative approach for analyzing the presence of environmental ...
Patterns of Strengths and Weaknesses in Children’s Knowledge about Fractions Journal of Experimental Child Psychology (2012)
The purpose of this study was to explore individual patterns of strengths and weaknesses in children’s mathematical knowledge about common fractions. Tasks that primarily measure either conceptual or procedural aspects of mathematical knowledge were assessed ...
Sources of Group and Individual Differences in Emerging Fraction Skills Journal of Educational Psychology (2011)
Results from a two year longitudinal study of 181 children from fourth through fifth grade are reported. Levels of growth in children’s computation, word problem, and estimation skills using common fractions were predicted by working ...
Time and Resource Limits on Working Memory: Cross-Age Consistency in Counting Span Performance Journal of Experimental Child Psychology (2003)
This longitudinal study separated resource demand effects from those of retention interval in a counting span task among 100 children tested in grade 2 and again in grades 3 and 4. A last card large ...
