Presents the results of a study on questions invoked to correct declarative knowledge deficits while readers processed science texts explaining natural phenomena. Focuses on finding out what kind of questions are asked by students who read these texts and how task demand influences the quantity and quality of formulated questions. (Contains 42…

Describes a study designed to determine whether the Biology Critical Thinking (BCT) project (which incorporates activities for developing specific critical thinking skills into the biology curriculum) enhances critical thinking skills and how it affects students' biological knowledge and classroom learning environment. Results indicate that BCT…

Investigated is the extent to which students' nonscientific beliefs change by comparing before and after instruction as a function of students' reasoning skill. Nonscientific beliefs discussed include special creation, orthogenesis, the soul, nonreductionism, vitalism, teleology, and nonemergentism. (KR)

Investigates the effect of a directed-inquiry approach to learning science process skills and scientific problem solving in the high school biology laboratory. Reports no main effect of the approach but an interaction effect of the approach and cognitive development. (Author/YP)

Utilizes a quasiexperimental design to examine the impact of microcomputer simulations on environmental problem solving by community college students. The experimental group of students (n=34) showed a highly significant improvement in problem-solving skills after being exposed to three simulation models that focused on lake pollution analysis,…
