Attention to core concepts in science and engineering in early education has grown recently, and understanding levers as force amplifiers can be recognized as one of these. Previous studies focused on two-sided levers and do not provide sufficient information about children's knowledge of levers as force amplifiers, nor about their learning and…

In this study, we explore how two different prompt types within an online computer-based inquiry learning environment enhance 392 7th grade students' explanations of evolution with three teachers. In the "elaborating" prompt condition, students are prompted to write explanations that support the accepted theory of evolution. In the…

Investigates the effects of combined learning cues (pretest and behavioral objectives) on the achievement levels of teachers in an inservice course. Subjects receiving the combined learning cues did not achieve at a significantly higher level than did those who did not receive the combined learning cues. (CP)

Investigated if the attitude of science students can be predicted from their nonverbal behavior. (Author/GA)

Explored are the use of cues and their possible interaction with learner ability in concept formation under inductive instructional methods. Two inductive treatments, cued and noncued, were administered to ninth- and tenth-grade students. Results indicate significant aptitude treatment interaction with verbal comprehension abilities and the two…
