This mixed-methods investigation compared the relative impacts of instructional approach and context of nature of science instruction on preservice elementary teachers' understandings. The sample consisted of 75 preservice teachers enrolled in four sections of an elementary science methods course. Independent variables included instructional…

The impact of summer science-enrichment programs on high-school students' science motivation and confidence was evaluated in a 7-month period following program completion. The programs took place on a college campus. The splashdown effect was defined as program-related changes the program graduates recognized in themselves that became apparent to…
