Techniques of classroom observation were used to increase teachers' awareness of the variable participation of boys and girls in science and craft lessons. The work indicates that considerable efforts may be needed to achieve the balanced participation of girls. (JOW)

Research in science education demonstrates the importance and effectiveness of the hands-on approach in student learning. Activity- oriented instruction offers multi-modal opportunities for learning science. However, there is very little research on the sensory nature of hands-on science learning. How do science educators describe lab activities…

This multi-participant case study used a phenomenological lens to understand the ways that science teachers make sense of implementing instructional innovations following their participation in a year-long biotechnology professional development program. Sources of data included a series in-depth interviews used to collect teachers' stories of…

The guide presents information about ordering, using, storing, and maintaining chemicals in the high school laboratory. The guide also provides information about chemical waste, safety and emergency equipment, assessing chemical hazards, common safety symbols and signs, and fundamental resources relating to chemical safety, such as Material…

This paper describes a study conducted on the lab sections of the general biology course for non-science majors at the University of New England, and reports findings of student misconceptions about photosynthesis and the mass/carbon uptake during plant growth. The current study placed high technology analytic tools in the hands of introductory…

Alabama Science in Motion (ASIM) is a statewide in-service and outreach program designed to provide inservice training for teachers in technology and content knowledge. ASIM is also designed to increase student interest in science and future science careers. The goals of ASIM are to complement, enhance, and facilitate implementation of the…

The purpose of this study was to compare in greater depth the qualitative differences between what previous researchers have called a deep versus surface approach to learning science. Six grade 8 students judged as typical using a deep or surface approach were videotaped or audiotaped during class group laboratory activities in a chemistry unit.…

Describes the construction and operational procedures of a spark-timing apparatus which is designed to record the back and forth motion of one or two carts on linear air tracks. Applications to measurements of velocity, acceleration, simple harmonic motion, and collision problems are illustrated. (CC)

Safety procedures used by Department of Chemistry at the University of Akron are discussed. These include policy that no chemicals are stored in the teaching laboratories. Instead, dispensing stockrooms are used to service the laboratories. Other aspects discussed include ventilation procedures and development of microprocessor use in stockrooms.…

Current and post World War II scientific research at the Los Alamos National Laboratory (New Mexico) is discussed. The operation of the laboratory, the Los Alamos consultant program, and continuation education, and continuing education activities at the laboratory are also discussed. (JN)

Briefly describes different designs for college chemistry laboratories to help mobility handicapped students working in them. (SK)

Presents specific techniques for lectures and demonstrations in acoustics for deaf students. (SK)

Provides methods for making instruments and supplies accessible to the visually impaired student in the chemistry laboratory and classroom. (CS)

Analyzed are university instructor behaviors in introductory and advanced level laboratories of botany, chemistry, geology, physics and zoology. Science Laboratory Interaction Categories--Teacher (SLIC) was used to assess 15 individual categories of teacher behaviors in the areas of questioning, giving directions, transmitting information,…

The results of using laboratory instruction as part of the total biology program in the Biological Sciences Curriculum Study are reported. (Author/SA)
