Reviews several schemes for organizing science laboratory objectives and activities and for analyzing several techniques designed to measure these laboratory outcomes. The need for further study and analysis of psychomotor behaviors in science education is emphasized. (HM)

Discusses hazards involved in the storage of flammable liquids, particularly those requiring refrigeration. (SL)

Describes an introductory individualized physics laboratory system for science and engineering students. (SL)

Describes the computerization of student academic records for a science course with multisection laboratories. (SL)

Smaller amounts of materials are used in organic chemistry experiments as a means of improving air quality in the laboratory. Outlines benefits from this approach and describes two representative experiments in detail. These experiments are the Cannizzaro reaction and preparation of an aromatic nitrile. (JN)

Examination of relationships between manner of utilization of human and material resources and secondary school students' achievement in and attitude toward science found that frequency of use of laboratory resources had highest positive correlation with achievement, followed by quality of use of laboratory resources. Quality of use of laboratory…

Describes an apparatus that uses liquified gases to wash solids. Discusses the procedures and processes used to do a wash with liquid sulfur dioxide. (CW)

The author describes the application of the vocational method of instruction, a technique focusing on real-world laboratory settings and private sector involvement, to the programs of an academic high school, Thomas Jefferson High School for Science and Technology in Fairfax County, Virginia. (CH)

Discusses two factors to consider when initiating advanced placement (AP) chemistry, namely, the quality of those teaching the program and the time necessary to teach the relevant concepts. Suggests offering laboratory sessions during evening hours as an alternative to traditional daytime arrangements for laboratory blocks. (JN)

An organic chemistry laboratory has been designed around independent laboratory projects that are done by groups, thus exposing students not only to a research experience but also to one that is more realistic and like the one they will be in as professional chemistry chemists. Instructional strategies used are described. (JN)

Determined student opinion of the investigative laboratory by surveying both students who had completed an introductory biology course using this format and another group of more advanced students who had taken other courses since this one. Results show that a majority of students feel the format improved their problem-solving skills. (JN)

Describes the plan submitted by the Nuclear Science Advisory Committee to the Department of Energy and National Science Foundation urging construction of an ultrarelativistic heavy-ion collider designed to accelerate nucleon beams of ions as heavy as uranium. Discusses the process of selecting the type of facility as well as siting. (JM)

Briefly considers the nature of physics laboratories and their role in the physics curriculum. Also considers three valuable outcomes of laboratory experiences: using equipment, doing real experiments, and handling phenomena. (JN)

It is increasingly important for physicians to develop competence in ordering and interpreting laboratory tests. The goals, organization, instructional approaches, and assessment of a course offering systematic instruction in laboratory medicine are described. (Editor/LBH)

This booklet contains information and guidelines for the safe use and handling of chemicals in laboratories and student classrooms. The theme of this handbook is prevention of accidents with chemicals which involves chemical knowledge and the habit of safety. Topics include: (1) safety in the use and handling of hazardous chemicals; (2) teaching…
