Investigates the attitudes of high school students (grades 11 and 12) toward physics and physics teaching including reasons for taking or not taking physics and reasons for considering or not considering a career in physics teaching. Provides frequency tables of responses to the questions. (YP)

Evaluates and compares common eyewash stations currently being used in laboratories. Discusses types available, installation, water supply needs, and maintenance. Lists current OSHA eyewash station standards. (ML)

Reexamines the electronic structure of water considering divergent views. Discusses several aspects of molecular orbital theory using spectroscopic molecular orbitals and localized molecular orbitals. Gives examples for determining lowest energy spectroscopic orbitals. (ML)

Describes why specific forms of orbitals used to interpret spectroscopy involving electronic transitions may not say much about the electronic structure of molecules. Discusses several theoretical approaches to explain the anomoly. Determines that the Lewis electron-pair model for molecules is a good predictor of spectroscopic results. (ML)

Considers two types of laser applications in kinetics. Explores short laser pulses to prepare a reactant in a known state and a continuous laser as a probe to monitor specific species in a reaction. Describes how lasers work and provides several examples of kinetic reactions. (ML)

Describes a simple laboratory procedure for changing sodium carbonate into sodium chloride by adding concentrated HCl to cause the reaction and then evaporating the water. Claims a good stoichiometric yield can be obtained in one three-hour lab period. Suggests using fume hood for the reaction. (ML)

Recommends using iodide ions and peroxodisulfate ions for studying rate laws instead of the standard iodine clock for kinetic study. Presents the methodology and a discussion of the kinetics involved for a laboratory experiment for a high school or introductory college course. (ML)

Describes a biophysical chemistry experiment that introduces students to globular protein conformation and microcomputer analysis of initial rate data for the unfolding of proteins. Presents background, materials needed and methodology. Uses a visible spectrometer for analysis. Lists educational benefits derived from the experiment. (ML)

Sixty hearing-impaired students, aged 12-22, studied one of four instructional formats describing basic science concepts. Comprehension gains were measured using a pretest-posttest procedure. Formats which featured highly pictorial content and simplified English produced significantly higher mean gain scores than formats with less pictorial…

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…

Demonstrates how science instruction can only be effective when teachers are aware of differences in children's language and their culture. The author argues that it is important to recognize when linguistic or cultural understandings lead children to wrong answers that to them seem totally logical. (GR)

A high school teacher examined how using technology in his chemistry classroom would affect students' attitudes and motivation. Observations, interviews, and surveys indicated that students stayed on task longer, wanted to come in to finish labs, wanted to know how they could improve, and felt they understood certain concepts better. (SM)

Examines the cognitive and affective impact of a multimedia editing task. The study examined how junior high school students used multimedia to teach science topics to themselves and others. The results showed that, although the technology had an important role in student activity, the task itself was the main motivational aspect. (Contains 34…

Using Piagetian tasks designed to assess specific mental structures, researchers investigate the relationship between logical thinking structures and the ability of students to construct and interpret line graphs. Results revealed that a significant correlation exists between the aforementioned variables. Suggests and cautions that only at certain…

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)
