In this article, we present the results of a qualitative research project on the effect of motion analysis activities in a Video-Based Laboratory (VBL) on students' understanding of position, velocity and frames of reference. The participants in our research were 48 pre-service teachers enrolled in Education Departments with no previous strong…

The article describes a program sponsored by International Business Machines Corporation (IBM) in which approximatey 60 children (14 to 17 years old) gifted in science spent much of 1941 after school hours in a science laboratory in IBM's showroom building. A number of these former students have achieved such positions as head of Goddard Space…

This paper deals with science laboratory assignments and physical education activity hours as aspects of the teaching load. The equation of laboratory and lecture hours was on a percentage figure, e.g., a one-to-one value was shown as 100% and two laboratory hours to one lecture hour was 50%. Seventy usable replies (from 79 inquiries) showed an…

Inexpensive, low-density polyethylene tubing has physical characteristics about midway between glass and rubber. For many laboratory uses it may be superior to both. (BB)

Rebuttal to a previous article maintains that laboratory experiences help students further develop their reasoning abilities. (Author/MLF)

This article discusses the involvement of the accreditation organization, the regulatory agencies, the consensus standards-writing organizations, and the laboratory community in the establishment of accreditation programs. (BB)

Describes procedures for the disposal of chemicals commonly used in secondary school chemistry laboratories. Special reference is given to inorganic salts. It is suggested that cyanides and other highly toxic salts should be disposed of by experts. (MA)

Gives recommendations for the establishment of science laboratory programs in elementary schools, cites research on various types of programs and provides an extensive list of texts that can be used. (MS)

Briefly reviews arguments for and against high school science laboratory instruction and suggests using the microcomputers as a laboratory instrument. How the microcomputer-based laboratory (MBL) works is explained and some hardware and software packages are noted. (MBR)

Three science departments share lecture facilities in one compact building. (Author)

Describes a science facility built at Seattle Pacific University for approximately 70 percent of the capital cost of a conventional science building. The building serves seven disciplines on a regular basis. The operation of the multidisciplinary laboratory, special features, laboratory security, and student experience/reactions are highlighted.…

Provides an alphabetical listing of laboratory instruments and equipment and the names and addresses of their manufacturers. (CS)

Discusses issues raised by the English Health and Safety at Work Act, legislation regulating laboratory safety in industry and in schools in Great Britain. (SL)

Explores the Competency Tripod model and flow diagrams as two sources for enabling students' metacognition in a second year undergraduate chemistry laboratory. Results indicate that all four students engaged in metacognitive practices, all believed that flow diagrams are extremely useful, and all understood the Competency Tripod model, but only…

Presents an activity to teach buoyancy. The lab determines what mass of sand can be added to the open end of hollow plastic containers of various shapes so that objects just float at the surface, without sinking, with their entire volume submerged. Discusses Archimedes' principle and aligns with current national science education standards.…
