Investigates the relevance and concomitant impact of sociocultural experiences upon the scientific literacy of 87 students, aged 13 to 16, concerning their comprehension and assimilation of scientific data involving solar eclipses. Results indicate that the students' nonscientific conceptions about solar eclipses, generated through sociocultural…

Found grades in science achieved by tenth-grade general science students correlated with their scores on Propositional Logic Test. The students' ability level was consistently related to the pattern of errors they committed on that measure. Mean scores were lowest on a subtest of ability to use the bicondition and implication, higher on the…

Focuses on the conceptual change processes of 17 fourth-grade students as they grapple with the abstract concept of human rights. Discusses limitations and successes in students' learning within the framework of conceptual change and motivation research. (CFR)

The "at-risk" designation attached to low-achieving children frequently sets them up for failure. Remedial programs are often ineffective, and skill drills rob students of in-context reading opportunities. Models like Success for All are so prescriptive that students cannot participate in open-ended discussions of literature. Unjust…

Process/product instruments of the 1970s attempt to evaluate teaching based on classroom observations. Performance-based teacher assessment is an ineffective, inappropriate method that does not truly assess teaching.
