Examines the differences between the expectations of high school teachers and college chemistry instructors concerning students who plan to study college chemistry. Focuses on questions dealing with knowledge of chemical concepts and skills using those concepts. A plan of action is suggested. (YP)

Described is a reliable and predictable laboratory experiment which represents the result of an integrated approach to design with an emphasis on teaching. Notes the flat-celled rig has logged over 100 hours service in 2 years without any problems. (MVL)

Assessed is the level of scientific and natural resource knowledge possessed by fourth-, eighth- and eleventh-grade students. Misconceptions are noted. Discussed are implications for teaching about acidic deposition. (CW)

Describes a "tracing the sun" worksheet combining models with computer programs and classroom discussion. Provides the worksheet including the nine steps of the activity and several discussion questions. (YP)

Describes experiences for engineering students to develop spatial awareness and reasoning capability. Describes geometric modeling, basic geometric concepts, operations, surface modeling, and conclusions. (YP)

Examines whether young children hold naive conceptions of speed and whether the nature of their concepts could be a causal factor in pedestrian accidents. Finds that children hold a range of beliefs regarding the concept of speed that would place them at risk. (Author/YP)

From an analysis of 14 secondary student's actions and thought processes, it was found that technology's level of information affected the focus of student observations. The microcomputer group focused primarily on the graph while other groups exhibited multiple foci. The discussion data also reveal that students have three main ideas about how…

Describes a teacher education project where preservice and inservice teachers were trained in the use of hands-on science conducted in cooperative-learning groups. The preservice teachers then conducted sessions with the inservice teacher's students to enhance the learning of the cooperating teacher. (PR)

A teacher describes her science class' successful inclusion of a student with Rett Syndrome. Included in the article are the classroom implications of the disease and strategies for ensuring that all students receive the best science education available. (ZWH)

A teacher shares three instructional aids that she used to teach blind as well as sighted students the basic principles of chemical bonding.(ZWH)

Describes historical accounts of the manipulation and importance of the Earth and its mineral resources. A foldout, "Out of the Rock," provides a collection of activities and information that helps make integration of the aforementioned concepts easy. (ZWH)

Describes a study of eighth-grade students that investigated the impact of computer simulations on students' ability to generalize scientific concepts from classroom to naturally occurring problems. A curriculum for teaching thermodynamics that was reformulated to emphasize integration of understanding is described, and student reactions are…

Discusses the early recognition of chaos as seen in Poincar's work solving dynamical problems. Proposes five examples from which an inventory of the manifestation of chaos can be inferred. Discusses some instructional consequences of the development of ideas of chaos. (MDH)

This study investigated the relationship between factors believed to contribute to the formation of environmental attitudes by college nonscience majors (n=136) attending an environmental studies course. Factors investigated included environmental attitudes, decision defensibility, and the linkage of affective and cognitive domains. Reports that…

Presents results of intensive clinical interviews with 11 high school chemistry students representing a broad range of achievement levels as selected from 180 students who completed a written test upon completion of an instructional unit on chemical change. Results indicate that students commonly experience difficulties in chemical knowledge,…
