The project uses a cross-sectional research design and will generate evidence that is causal [experimental]. Original data are being collected on preschool and young school-aged children using project designed measures of pattern-learning (i.e., Do children learn and generalize patterns present in the materials they encounter?) and measures of transfer, including the speed of learning new patterns. The experiment involves comparing different types of exhibits (those with a very task-focused structure and those with a more exploratory structure) with several alternatives. Analysis plans include statistical comparisons (t-tests, ANOVA models) of learning rates/accuracy across different exposure conditions.
