Reviews safety and emergency equipment in their application to chemical laboratories. Discusses American National Standards (ANSI) for equipment. Presents practical considerations for the placement and purchase of equipment. (MVL)

Discusses the use of robotics in the analytical chemistry laboratory. Suggests using a modular setup to best use robots and laboratory space. Proposes a sample preparation system which can perform aliquot measurement, dilution, mixing, separation, and sample transfer. Recognizes attributes and shortcomings. (ML)

This standard lesson on identifying salt and sugar crystals expands into an opportunity for students to develop their observation, questioning, and modeling skills. Although sugar and salt may look similar, students discovered that they looked very different under a magnifying glass and behaved differently when dissolved in water. In addition,…

Studying "Caenorhabditis elegans" ("C. elegans") live cultures provides excellent opportunities for authentic inquiry in a high school anatomy and physiology or other biology lab course. Using a digital dissection microscope, a student can photograph the organism during various stages of development and study and analyze the images. In this…

This life science activity module was designed to facilitate student conceptualization of plant growth. It is intended for use primarily in elementary grades but may be useful at higher grades. It provides students with hands-on experience and observational skill development. The package provides: (1) a teacher background sheet; (2) an activity…

This Chemistry-Materials Laboratory Project Book, assembled through a survey of science instructors in vocational-technical schools in Connecticut, is intended to meet a variety of needs. It can serve as an idea book, with the instructor taking from it as needed and adding or substituting material related to class interests; as a guide book for…

This Physics Laboratory Project Book, assembled through a survey of science instructors in vocational-technical schools in Connecticut, is an extension of the Chemistry-Materials Laboratory Project Book (see note) and is intended to meet a variety of needs. It can serve as an idea book, with the instructor taking from it as needed and adding or…

AN INTERIM SURVEY DESIGNED TO SUPPLY STATISTICAL DATA TO ANYONE INVOLVED IN PLANNING AND EVALUATING FOREIGN LANGUAGE PROGRAMS IN SECONDARY SCHOOLS IS PRESENTED IN THIS REPORT. FOREIGN LANGUAGE ENROLLMENTS BY PERCENT OF HIGH SCHOOL POPULATION, BY LANGUAGES, AND BY LANGUAGE LEVELS ARE TABULATED. FOREIGN LANGUAGE OFFERINGS ARE LISTED ACCORDING TO THE…

The language media laboratory described in this proposal is intended to provide for the implementation of broader instructional objectives than language laboratories of previous years, including the dial access type. The proposal is divided into three main sections: (1) program rationale; (2) programs and services; and (3) design of the language…

In a Biology laboratory for the non-science major, a series of programed booklets, 8mm cartridge films, and 35mm slides were used with standard laboratory equipment and materials. By the end of the second semester, 28 programed sequences with linear and branching strategies had been designed and tested. Students completed attitude questionnaires…

Rationale and facilities of the University of Hawaii's language laboratories are examined. The two-fold summary defines present (Fall 1968) and future (Fall 1969) needs, physical facilities, expected language enrollments, schedules, staff, services, research, experimentation, and planning. Also treated is the financial aspect of laboratory…

An experimental sound- and video-library has recently been established by the Centre de Recherches et d'Applications Pedagogiques en Langues at the University of Nancy II. This article describes the functioning of the library system and gives a brief explanation of the underlying pedagogical principles which have guided the design, choice of…

The unit is designed to provide approximately 10 hours of instructional time for learners in grade 3. The primary intent of the unit is to help the learner develop an awareness of sound-extending and sight-extending tools. Four major goals and 18 performance objectives are addressed in the unit. The major topics included in the unit stress: (1)…

A basic French course, intended to stress equally the audio-oral and spelling-reading skills, is described. Intermediate courses, specialized courses (in literature, phonetics, stylistics, civilization, and simultaneous interpretation), and the comprehension of scientific material are also discussed. Descriptions of these courses stress the use…

The experimental use of computer assisted instruction (CAI) to replace conventional laboratory sessions for first-year German students at the State University of New York, Stony Brook, is described. Materials used in the program are outlined, including hardware, pre-text program, text program, student manual, and diagnostics. Pedagogical…
