A survey of the different technical communications and information-related activities of 305 engineers and scientists from 3 sites of the Philips Laboratory, an Air Force research and development laboratory, found that scientists have a closer affinity for libraries and traditional information sources than do engineers. Eight tables depict survey…

Analyzes nine high school biology manuals to determine how well they promote the basic and integrated science process skills that are involved in scientific inquiry. Results indicate that the manuals seldom enable students to use their knowledge and experience to pose questions, solve problems, investigate natural phenomena, or construct answers…

Describes an experiment designed to measure absolute zero using Charles' Law without the use of mercury. Provides the procedure and details of the apparatus and includes experimental results obtained using the apparatus. (DDR)

Suggests that one place a writing center should be is online, as a virtual space of unlimited size in the form of a "writing cooperative," a term the article defines and discusses. (TB)

Examines how physical proximity between teachers and students differs between classroom and computer lab environments. Finds that teachers either worked at intimate (up to 1.5 feet) or personal (1.5 to 4 feet) distances with students or, except rarely, did not approach closer than 12 feet or did not interact at all. (SR)

Presents a laboratory activity to teach medical biology to undergraduate nonmajor business students. Uses herbalism as the theme concept to integrate subjects, such as anatomy, physiology, medical theory, and terminology. Includes topics, such as herb collection, medicine preparation, and herb storage. (SOE)

Helps middle school students understand the concept of solubility through hands-on experience with a variety of liquids and solids. As they explore factors that affect solubility and saturation, students gain content mastery and an understanding of the inquiry process. Also enables teachers to authentically assess student performance on several…

Investigated the use of a hands-on laboratory program for improving student attitudes toward science and increasing student achievement levels in science knowledge. Findings indicated that students who had laboratory instruction scored higher in achievement and showed a positive correlation between attitude and achievement. No significant…

Describes two variations of an air sampler and analyzer that are inexpensive to construct, easy to operate, and designed to be used in an educational program. Variations use vacuum cleaners and aquarium pumps, and white facial tissues serve as filters. Samples of air pollution obtained by this method may be used from early grade school to advanced…

Describes an integrated approach to teaching a biochemistry laboratory focusing on the relationship between the three-dimensional structure of a macromolecule and its function. RNA is chosen as the model system. Discusses curriculum and student assessment. (AIM)

Describes an activity demonstrating the importance of photoperiod on plant development. Uses the plant devil's backbone for the experiment and studies the details of photoperiodic requirement for plantlet formation. (Contains 12 references.) (YDS)

Focuses on practices related to the use of a microcomputer-based laboratory (MBL) in a high school chemistry course in which students studied gases and kinetic theory. Reports that little or no higher order thinking was employed as students engaged in using the MBL and that some alternative conceptions were still evident. (Contains 42 references.)…

Uses microcomputer-based laboratories (MBL) to teach Newton's second law and the impulse-momentum relationship with a high degree of precision and accuracy while applying forces that change in an arbitrary way. (YDS)

Defines the relationship that is intended between classroom-based and laboratory based activities, private study and language class, individual and collective effort, and computer-centered and teacher-led learning. Suggests that the aid the computer can provide can be effectively brought into the classroom as an integral part of the teacher's own…

Conducts a science safety survey of science educators across the nation to assess their safety understanding and to determine the availability and understanding of strategic safety items. Discusses findings, problems, and implications for science supervisors. (KHR)
