CAESART will directly respond to the vision of the Next Generation Science Standards (NGSS) by addressing the nationwide gap in the availability of high-quality science instruction and assessment for young students (grades K-2). CAESART will connect and build on existing networks of science researchers, leaders, and practitioners at the state, district, and school levels to engage in research and to share information generated through Center activities. CAESART's approach addresses several q...

The purpose of this project is to develop and validate an Item Response Theory (IRT) - based, computer adaptive test (CAT) to assess Latino preschoolers’ science knowledge and skills. The research team will extend current IES-funded work (Lens on Science: Development and Validation of a Computer-Administered, Adaptive, IRT-Based Science Assessment for Preschool Children) that is in the final stages of developing and validating a touch screen computer-adaptive child assessment of scienc...

In recent years, early childhood education has emphasized children's school readiness in the domains of language, literacy, and mathematics. To date, there has been limited systematic focus on science education in preschool. There is a need for the development, implementation, and evaluation of preschool science curricula that will promote young children's understanding of basic science concepts. The purpose of this project is to conduct an efficacy study of a comprehensive early childhood ...

Recent emphasis has been placed on science as a school readiness domain. However, an obstacle to conducting research and evaluation on early childhood science programs is the lack of appropriate, reliable, and valid direct assessments of children's science knowledge and process skills. This measurement project will fill the need for a reliable and valid direct assessment of preschool children's science. A collaborative team from the University of Miami, the Miami-Dade County Head Start/Early...
