Laboratory techniques, instructional materials, and teaching methods for secondary school chemistry topics are provided. (CP)

Topics in biology A-level projects are briefly described. (CP)

A home economics classroom designed to conserve energy and encourage students to practice a simpler life-style is described, and a check list of forty-five suggestions for developing the home economics laboratory as an environmental model is presented. (BM)

A simple check list originally designed as an evaluation tool for tapes and tape series used in language instruction. The check list includes all aspects of the tape: its contents, its reference to textual material and its overall effect. There are also eight questions for the teacher's opinions. (AMH)

Maintains that teaching phonetics should be aimed at enabling the learner to correct himself and that intonation, rhythm and suprasegmental phonemes have commonly been neglected. Describes the value and use of the SUVAG-Lingua Frequency Filter for correcting pronunciation, individually and in groups. (Text is in German.) (IFS/WGA)

Describes three situations in which computer software was used in a chemistry laboratory. Discusses interfacing voltage output instruments with Apple II computers and using spreadsheet programs to simulate gas chromatography and analysis of kinetic data. Includes information concerning procedures, hardware, and software used in each situation. (CW)

Describes the construction and uses of a low cost fermenter reaction vessel which is suitable for laboratory growth of microorganisms by continuous and batch cultures from plastic soft drink bottles. Lists materials, discusses modifications that can be made and gives examples of use. (CW)

Criticizes the way organic chemistry teaching laboratory experiments are approached from the viewpoint of physical chemistry. Compares these experiments to cooking. Stresses that what matters is not the practice of the finger skills of organic chemistry but practice in the style of thinking of organic chemists. (CW)

Describes the construction and use of a life-size model which shows blood flow under normal and pathological conditions. Four experimental procedures (single vessel occlusion, dilation of distal vascular bed, single artery stenosis, and multiple artery stenoses) typical of those demonstrated by the model are discussed and diagrammed. (DH)

Background information, procedures used, and typical results obtained are provided for experiments in which caterpillars are used to investigate energy-flow relationships. Areas in which the experiments could be used include ecology, applied biology, and animal feeding. (DH)

Secondary physics students were interviewed to determine their expectations/actions in laboratory work. Results indicate preference for laboratory activities because such exercises help students remember, are less confusing, and more concrete. Use of the laboratory as an introduction to a concept, followed by discussion, was a key component to…

Describes a general purpose microcomputer-based system designed to support small-scale experimentation in the physical sciences in student laboratories. System requirements, teacher reactions, and educational implications are discussed; design criteria are established; and examples are given of the system's application to some simple experiments.…

Discusses the use of microcomputers in science education: (1) computer-assisted instruction; (2) testing; (3) data processing; (4) simulation; (5) teacher assistance; and (6) data collection. Gives educational applications of microcomputer-based laboratories, pointing out advantages and disadvantages. Outlines current drawbacks and makes…

Presents the historical, technological, and pedagogical factors that led to high expectations in the use of language laboratories for teaching foreign languages. Presents findings of five studies on laboratory effectiveness showing that efficiency tests were largely irrelevant and inconclusive. Includes 10 proposals for language laboratory use.…

Described is an inexpensive wave tank used to study the amplitude of tsunamis travelling down a channel of decreasing depth. A detailed discussion to theory and computations is included. (SL)
