Tutors are true professionals who understand that even though their own philosophical stance toward teaching may differ from an instructor's, they have an obligation to do whatever the professor requires. However, because they work more closely with them, the tutors are in a better position than the teacher to see when the students are having…

This course is intended for personnel who have an operational or administrative responsibility for the design and use of bioassay and biomonitoring, and who have no experience in conducting static bioassays. The training consists of classroom discussions, laboratory exercises and demonstrations, and demonstration and observation activities. (CO)

The Research and Development Exchange (RDx) is a network of eight regional educational laboratories, one university-based research and development center, and a consortium of seven state education agencies working to support state and local school improvement efforts. The RDx has four goals, designed to support dissemination and school improvement…

Defining a learning center as a classroom area containing several learning stations where students may work independently with materials which teach, reinforce, or enrich their skills, this guide presents a number of ideas for use in the visual motivation display area of such a center. Suggestions for displays for the various teaching stations are…

This paper describes the construction and use of a simple salinometer. The salinometer is composed, mainly, of a milliammeter and a battery and uses the measurement of current flow to determine the salinity of water. A complete list of materials is given, as are details of construction and operation of the equipment. The use of the salinometer in…

This module introduces the student to a formal study of probability. The lessons progress from elementary notions of least likely to more complex considerations of the probability of occurrence of one or more possible outcomes. Probability is introduced in an empirical sense through experimentation and investigation. In the later experiments, the…

THE LANGUAGE LABORATORY IS ESSENTIALLY AN AUDIOVISUAL AID WHICH NOT ONLY STORES INFORMATION, BUT ALLOWS THE STUDENT TO CONTROL RATE OF PRESENTATION, CONTINUALLY EVALUATES THE STUDENT'S PERFORMANCE, AND APPRAISES HIS ACHIEVEMENT. THE EFFECTIVE PERFORMANCE OF A TEACHING MACHINE DEPENDS HEAVILY ON THE ORGANIZATION OF MATERIAL STORED IN IT, WHICH IN…

SEVERAL STUDIES OF LABORATORY TRAINING PROGRAMS IN INDUSTRY ARE ASSESSED IN TERMS OF THEIR POTENTIAL USEFULNESS (DO THEY ACCOMPLISH INTENDED CHANGES IN PARTICIPANTS THAT ARE LASTING OR SELF-REINFORCING, AND HOW DO THEY COMPARE WITH OTHER METHODS IN ACCOMPLISHING SIMILAR GOALS) AND ACTUAL CONTRIBUTION (DOES PARTICIPATION LEAD TO LASTING CHANGE IN…

THE PAPER DESCRIBES AUDITORY AND TACTILE ADAPTATION OF PHYSICS LABORATORY APPARATUS FOR USE BY BLIND STUDENTS, TOGETHER WITH FIVE METHODS OF DRAWING RAISED LINE AND INDENTED DIAGRAMS FOR USE IN PHYSICS EXPERIMENTS. A SURVEY OF PHYSICS LABORATORY METHODS IN SCHOOLS FOR THE BLIND IN THE UNITED STATES AND SEVEN FOREIGN COUNTRIES, AND TWO SIMPLE…

THE ROLE OF EQUIPMENT IN THE NEW TECHNOLOGIES OF INSTRUCTION WAS EXPLORED. SOUND EQUIPMENT, EDUCATIONAL TELEVISION EQUIPMENT, AND LEARNING LABORATORIES WERE DESCRIBED. OTHER VOLUMES IN THIS SERIES ARE ED 003 738 THROUGH ED 003 746. (JK)

This module is designed to give the learner an understanding of the nature of light and how its properties are used in the design of spectrophotometers. Problems promote the use of spectrophotometers in qualitative analysis, the optical elements used in a monochromator, and the physical properties of the prism and the diffraction grating. Other…

This report addresses the initial phase of a multiphase effort to install Training Assistance Technology (TAT) capabilities on a submarine combat system trainer (SCST), and evaluate their effectiveness during a formal training course. This phase addresses the (1) selection of the trainer and course with which to conduct the evaluation, (2)…

This series of experiments seeks to provide laboratory exercises which demonstrate concepts in Earth Science, particularly oceanology. Materials used in the experiments are easily obtainable. Examples of experiments include: (1) comparison of water hardness; (2) preparation of fresh water from sea water; (3) determination of water pressure; (4)…

This booklet contains an extensive checklist of statements and questions pertaining to safety precautions to be followed in school science laboratories. The planning of science facilities for optimum safety and the role of the teacher in providing for safety are also discussed. A separate section for dealing with mercury is also included. The…
