Reports long-term effects of intensive instruction in the cue attendance or hypothesis generation on open-exploration behavior of 120 ninth graders. Five dependent measures included: number of observed details; number and quality of hypotheses; and number and diversity of questions. Results suggest long-term benefits. (Author/JN)

Reported is a needs assessment conducted in 40 Massachusetts school systems to determine what elementary school science teachers perceive should comprise their inservice training. Findings suggest that programs focus on the metric system, environmental science, more science knowledge, and better science methods. (Author/SA)

Describes phase transition in solids and shows how soap films can be used to demonstrate this phenomenon. (Author/SK)

Presents results of a selective survey of schools using individualized instruction (II) in Great Britain and a detailed description of a particular II self-study zoology course at University College, Cardiff. (CS)

A national award for extraordinary achievement by a college faculty member was given by CASE to Mary Clark of San Diego State University. Clark, a distinguished teacher, scholar, author, and educational innovator, developed a course dealing with human nature, technological development, limited resources, politics, and world social structures. (MLW)

Determined the effect of using previsit instructional materials on student learning for a museum field trip experience. Ten earth science classes were assigned to experimental (instruction over field trip) and control (normal class instruction) groups. Found previsit instructional materials significantly increased student test scores. (DS)

Determines if elementary teachers' (N=138) understanding of SCIS concepts and teaching strategies change as a result of a televised inservice program using confidence levels as a criterion for understanding. Findings indicate that an inservice program consisting of televised sessions significantly improves teachers' understanding of SCIS concepts…

Described is Xavier University of Louisiana Piagetian-based general chemistry program. Laboratory experiments are in the learning cycle format and place emphasis on learning by doing. Aspects of the curriculum described include synopses of content covered, laboratory-preceding lectures, list of laboratory experiments covered, and evaluation of the…

Describes methods for collection, culture, observation, and making permanent stained preparations of the protozoan vorticella. Suggestions are made for experiments to investigate growth, reproduction, settlement, ecology, feeding, and osmoregulation. (CS)

Describes the preparation of selected aldehydes and ketones, alcohols, amines, phenols, haloalkanes, and tertiaryamines by differential scanning calorimetry. Technique is advantageous because formation of the reaction product occurs and the melting point of the product is obtained on the same sample in a short time with no additional purification…

Describes a study to determine (1) if introductory biology students (N=417) could master ecological concepts and improve their attitudes toward their immediate surroundings using a new unit, and (2) the best instructional format, with lecture materials brought inside or individualized instruction in the field via an audio-tutorial format.…

Describes a series of laboratory experiments and computer simulations of the motion of electrons in electric and magnetic fields. These experiments, which involve an inexpensive student-built electron gun, study the electron mean free path, magnetic focusing, and other aspects. (Author/HM)

Discusses the relationship between mathematics and science teaching on both the national and local school levels in the United Kingdom. The extent of cooperation between mathematics and science teachers in secondary schools is also discussed. (HM)

Describes a program developed to expose college chemistry students to some of the more modern information retrieval tools, as computerized online databases. Following classroom lectures and discussions, students individually develop a search statement relevant to their own research needs and run it in the Chemical Abstracts files. (BT)

Describes a laboratory technique for use in an undergraduate instrumental analysis course that, using the interpretation of window diagrams, prepares a mixed liquid phase column for gas-liquid chromatography. A detailed procedure is provided. (BT)
