Laboratory facilities should be designed with the most effective arrangement for maximum instructional efficiency and safety. Periodic evaluation and analysis should be used for improving instruction, abating safety hazards, and presenting an efficient learning environment. Attention should be focused on--(1) instructional program, (2) students,…

This handbook, written specially for the San Diego Public School System, contains detailed discussions on first aid, good laboratory practices, safety in the laboratory, and laws regulating the care and use of animals. The section on "First Aid" presents, in addition to standard first aid information, a discussion of first-aid kits for…

An argument for taping pattern drills without pauses is advanced as a means for allowing students to learn at their own rate. Insertion of pauses by the teacher and advantages of a foot pedal to control pauses are discussed. Examples are provided for two, three, four, and five cycle drills. (AF)

This is the first half of a two-part study of psychopedagogical problems in the language laboratory. A study of technical problems will follow. Major attention is directed to divisions of work (unities, elements, and phases), deferred comparison, deferred master control, audio-active feedback, the acquisition of new auditive processes, elimination…

This publication reviews the mathematical laboratory from three perspectives: a practical view of laboratories in operation, a review of related research, and a view of current laboratory evaluation procedures. After a discussion of definitions, types, and purposes of math labs, the first paper concentrates on their historical development in…

Design of laboratory animal facilities must be functional. Accordingly, the designer should be aware of the complex nature of animal research and specifically the type of animal research which will be conducted in a new facility. The building of animal-care facilities in research institutions requires special knowledge in laboratory animal…

This technical report is in three parts. Part I is a conceptual treatment of communication in which the human being is viewed as a goal-attainment system. The goal-attainment problem is defined as a discrepancy between the current state of the system and a specified goal state. Several forms of the communicative relationship are outlined. Part II…

To determine the long-run impact of the CERLI training program, the trainees' abilities to function as Specialists in Continuing Education (SCE) had to be measured and assessed. This assessment is a followup to "Assessment of the CERLI Training Program Specialist in Continuing Education" (EA 002 706). The document reports on attempts to…

An experiment involving two groups of 193 beginning secondary school students of French, German, and Spanish considers the instructional value of the electronic classroom as an alternative to the conventional language laboratory for the presentation of exercise materials. Experimental design hypotheses state that since more practice is possible…

Possibilities opened by video in the theory and practice of foreign language teaching are suggested. Among the advantages are: observation of mouth movements is important to articulation; gestures and facial expressions are an important part of communication; and language presented in social contexts can show socio-linguistic conventions.

Describes a laboratory activity that is adaptable to several levels of biology students. Discusses methods for obtaining hellgrammites, performing the experiment, and analyzing the data. Includes sample charts and graphs. (CW)

Described is a study designed to introduce students to the behavior of common invertebrate animals, and to use of the chi-square statistical technique. Discusses activities with snails, pill bugs, and mealworms. Provides an abbreviated chi-square table and instructions for performing the experiments and statistical tests. (CW)

Introduces two hands-on experiences, related to rotational motion and moment of inertia. Discusses the experimental procedures and provides figure of apparatus. (YP)

Introduces some ideas on teaching scaleup in chemical engineering. Discusses the instructional modes and the general and specific topics. Provides two examples of an experiment with equipment and safety issues. Shows the list of actual individual and team projects in an appendix. (YP)

Describes two computer simulation programs, "Nerve Physiology" and "Frog Heart," as practical alternatives to the use of live animals in class experiments. Discusses the potential of computer simulation as a feasible alternative to experiments with animals in the classroom laboratory. (CW)
