Teachers seldom reported providing students with metacognitive components of strategy instruction. Implications for teacher instruction in study strategies are…

A comparison was made of student understandings of marine science and marine resource concepts in two geographically distant but similar sociocultural regions of the United States. The study is based on the nature of ecological events, students' understanding in the context of meaningful learning, and the cultural context in which learning takes…

Reports on conceptual understanding and solution strategies for percent problems of (n=31) students representing 2 ability levels from grades 5, 7, 9, and 11.
