In order to compete in a global economy, students are going to need resources and curricula focusing on critical thinking and reasoning in science. Despite awareness for the need for complex reasoning, American students perform poorly relative to peers on international standardized tests measuring complex thinking in science. Research focusing on…

Different learning cycle sequences were investigated to determine factors accounting for success of the cycle, compared learning with conventional instruction, and examined relationships between Piaget's theory and learning cycles. Results show that the normal learning cycle sequence is the optimum sequence for achievement of content knowledge in…

Investigated the influence that changing the form of the learning cycle's exploration/expansion phases had on the content understandings developed by students and their attitudes toward the learning procedures used. The naturalistic data presented show that students believed learning physics is enhanced by the regular-form learning cycle (which…

Studies effects of verbal participation during enquiry on achievement among three differently treated groups of four eighth-grade classes each with I.Q. test, reading test, sociometric, and academiometric results taken into account. Indicated the preference of strategies involving more students, particularly more girls, in class discussion. (CC)

Examines the relationship between high school students' perceptions of their science learning environments and their motivation, learning strategies, and achievement. Discusses the focus of shared perceptions and instruction and indicates that shared perceptions focused on understanding and independent thinking positively predicted students'…

Reports on a study designed to investigate how the use of computer assisted instruction (CAI) tutorial programs, incorporating advance organizers and involving various sizes of groups of subjects, would affect achievement scores, retention scores, and rates of learning. (TW)

Discusses a study that examined the role of four cognitive factors (formal reasoning ability, prior knowledge, field dependence/independence, and memory capacity) on achievement in chemistry as measured by tests of lab application, chemical calculations, and content knowledge. Reports the significance of prior knowledge and formal reasoning…

Reports on a study to determine the effects of the presentation of questions inserted into texts for students in introductory biology. Results indicated that students reading the text with questions at the beginning of the paragraph scored significantly higher on achievement tests than the students reading without questions. (TW)
