Reports on a study comparing the use of the language experience approach and a traditional reading lab approach in which LEA students made equal or greater gains in verbal ability. (MKM)

Describes simple-to-construct instructional aids to be used in providing an intuitive approach to acceleration. Introductory mechanics involving velocity, distance and acceleration are discussed. (CP)

The injection of conversation/discussion sessions into English language laboratory exercises could help to achieve the major objective of teaching English as a foreign language--helping the learner to express himself in English. Steps in developing the method are outlined. (SW)

A high school electronics teacher describes the integration of technical report writing in the electronics program for trade and industrial students. He notes that the report writing rather than just recording data seemed to improve student laboratory experience but further improvements in the program are needed. A sample lab report is included.…

Describes an inservice education program for teachers of agricultural mechanics, undertaken by the Department of Agricultural and Extension Education at Mississippi State University, to improve teacher understanding of the need for safety in agricultural mechanics laboratories; to identify safety hazards in laboratories and their remedies; and to…

The planning process needs to integrate facility planning into the decision-making process. Two case studies are discussed: an assessment of resource-allocation policies for university chemistry research laboratories, and a model for evaluating the utilization of a community college. (MLW)

Discusses the need for visual aids in helping students recognize various minerals in a thin section. Describes the development of a manual of color photomicrographs designed to provide students with a more realistic view of minerals than can be provided by charts and diagrams. (TW)

Explains: (1) use of piezoelectric film (connected to power supply and oscilloscope) to reveal force-versus-time curves of bouncing balls; (2) use of bound wood splints or meter sticks to illustrate tree or tower stability; and (3) apparatus of co-axial discs with connected linking rods and suspended bobs to simulate waves. (DH)

Lists 100 specialists from libraries, instructional media centers, and computer labs in schools across the country and their projects or achievements using educational technologies during this past school year. (Author/LRW)

Discusses electron-loss spectroscopy and the experimentally observed excitation energies in terms of qualitative MO theory. Reviews information on photoelectron spectroscopy and electron transmission spectroscopy and their relation to the occupied and unoccupied orbital levels. Focuses on teaching applications. (ML)

Presents some strategies that have been used to overcome problems in instructional areas of introductory biology programs. Focuses on maintaining an emphasis on inquiry, developing the process of science, the design of process laboratory activities, reducing cookbook laboratory orientation, and educating staff. (CW)

Describes a basic biotechnology investigation that includes restriction and ligation of plasmid DNA, transformation of bacteria and cloning of these bacterial cells. Discusses laboratory procedures and another activity in the identification of unknown plasmids by studying agarose gel electrophoresis photographs. (CW)

Identifies a technique using methylene blue and glucose to explain a genetically related enzyme shortage causing blue skin in humans. Offers a laser technique to study solubility of silver salts of chloride and chromate. Encourages the use of models and class participation in the study of chirality and enantiomers. (ML)

Describes two introductory exercises designed to teach the fundamental ideas and methods of crystallography, and to convey some important features of inorganic and organic crystal structures to students in an advanced laboratory course. Exercises include "The Crystal Structure of NiO" and "The Crystal Structure of Beta-Fumaric Acid." (CW)

Describes a technique of impregnating small amounts of sandy sediment in a quick curing resin for microscopic examination. Details the preparation of materials. Suggests laboratory exercises based on this preparation. (CW)
