From Annual Meeting of NARST:

Currently in its third year of programming, the Virginia Elementary Science Institute aims to give teachers a background in problem-based, hands-on lessons. This Institute is part of the Virginia Initiative for Science Teaching and Achievement (VISTA), a $34 million, five-year grant from the U.S. Department of Education. VISTA is a multi-year scale-up program to validate prior research on elementary, secondary, and programmatic supports for science education. An independent evaluator report shows that VISTA positively impacts teachers’ beliefs surrounding science instruction, assessment, and how students learn; their confidence in teaching; their classroom practices; and their science content knowledge.
