In this study, the authors…

Science, technology, engineering, and mathematics (STEM) professional development for K-5 teachers often includes engineering design as a focus. Because engineering applications provide perspective to both teachers and their students in terms of how mathematic and scientific principles are employed to solve real-world problems (Baine, 2004; Roden,…

Today's World is in period of rapid development of science and technology. There is science and technology education that not based on rote, practical on the basis of development in science and technology. Misconceptions are a major obstacle in order to take the desired efficiency. Because concepts that learned wrong obstacle attainment of right…

This study traces the development of a vocabulary measure designed to assess multiple types of word knowledge. The assessment, which was administered in conjunction with a science unit about weather and the water cycle for third-and-fourth graders, included items for six knowledge types--recognition, definition, classification/example, context,…

Demonstrates the usefulness of the inclusion paradigm as a methodological tool in providing information about the conceptual breadth of selected social and nonsocial superordinate categories in children who exhibit some degree of inclusion logic. (HOD)

Two experiments with 42 second graders, 55 fourth graders, and 36 fifth graders investigated previous findings of a lack of strategic advantage for expert children dealing with information in their area of expertise. Results from using an expert-novice paradigm suggest that expert children's task advantage is mediated primarily by nonstrategic…
