RECOMMENDED STANDARDS FOR AUDIOVISUAL EQUIPMENT WERE PRESENTED SEPARATELY FOR GRADES KINDERGARTEN THROUGH SIX, AND FOR JUNIOR AND SENIOR HIGH SCHOOLS. THE ELEMENTARY SCHOOL EQUIPMENT CONSIDERED WAS THE FOLLOWING--CLASSROOM LIGHT CONTROL, MOTION PICTURE PROJECTOR WITH MOBILE STAND AND SPARE REELS, COMBINATION 2 INCH X 2 INCH SLIDE AND FILMSTRIP…

THIS STUDY DETERMINED WHETHER OR NOT DIFFERENTIAL BINAURAL STIMULATIONS CAN BE USED EFFECTIVELY TO IMPROVE PRONUNCIATION IN FOREIGN LANGUAGE TEACHING. THE OBJECTIVE WAS TO DETERMINE WHAT EFFECT HEARING SIMULTANEOUSLY THE TEACHER'S VOICE IN ONE EAR AND HIS OWN VOICE IN THE OTHER WOULD HAVE ON A STUDENT'S ABILITY TO COMPARE THE DIFFERENCES IN…

THIS SET OF CONSIDERATIONS HAS BEEN PREPARED TO PROVIDE PERSONS WORKING ON THE DESIGN OF NEW OR REMODELED LABORATORY FACILITIES WITH A SUITABLE REFERENCE GUIDE TO DESIGN SAFETY. THERE IS NO DISTINCTION BETWEEN TYPES OF LABORATORY AND THE EMPHASIS IS ON GIVING GUIDES AND ALTERNATIVES RATHER THAN DETAILED SPECIFICATIONS. AREAS COVERED INCLUDE--(1)…

IN ORDER TO ASSIST NON-TECHNICAL PEOPLE IN SCHOOLS TO CONDUCT A FIELD CHECK OF LANGUAGE LABORATORY EQUIPMENT BEFORE THEY MAKE FINAL PAYMENTS, THIS MANUAL OFFERS CRITERIA, TESTS, AND METHODS OF SCORING THE QUALITY OF THE EQUIPMENT. CHECKLISTS ARE PROVIDED FOR EVALUATING CONSOLE FUNCTIONS, TAPE RECORDERS, AMPLIFIERS, SOUND QUALITY (INCLUDING…

AN EXPERIMENT WAS DESIGNED TO TEST THE HYPOTHESIS THAT PROPER USE OF ELECTRO-MECHANICAL AIDS CAN RELIEVE THE TEACHER OF A GREAT DEAL OF THE ROUTINE WORK OF TEACHING FOREIGN LANGUAGES. HE WOULD THUS BE ALLOWED TO EXTEND HIMSELF EITHER QUANTITATIVELY OR QUALITATIVELY IN HIS WORK. THIS EXPERIMENT USES THE QUALITATIVE APPROACH. THREE GROUPS OF…

Provided are 45 experiments in chemistry which have been used successfully by students in secondary school chemistry classrooms. Additional investigations directed at further inquiry on the part of the student are included. The experiments are directed at the development of science process skills and many of the concepts and generalizations which…

This study is concerned with the effect of involving small groups in team research work in a large psychology class at Illinois State University. Phase I (fall) dealt with developing, organizing, and evaluating a lab team method and sought to have students actively participate in discussion of study questions and in team research by combining a…

This physics laboratory manual is the result of curriculum development begun at Aviation High School (New York City) in 1967. It represents a semester of advanced laboratory work for those students who have completed the usual course in physics. The 91 laboratory experiments included in the manual have been developed and modified through use for…

The present volume outlines the reasons, facilities, activities, schemata, and suggestions for setting up a functional social studies laboratory in the hope that the quality in social studies education will be improved. Approximately half of the book offers sources of materials for the benefit of teachers. Labs are not only a repository of…

Instructions for the construction of the following apparatus for the secondary school science laboratory are included in this issue of the Scottish Schools Science Equipment Research Centre Bulletin: a cheap water purifier using an expendable deionizer can; a simple amplifier suitable for detecting or displaying D. C. currents of 1 microamp or…

This publication should be useful for those who are interested in the theory and application of isotopes and radiation in agriculture and entomology. There are two main parts in the publication. Part I, entitled Basic Part, includes topics which an individual should know about radioisotopes and radiation. There are laboratory exercises included in…

Describes various aspects of chemical laboratory planning and construction, such as distribution of utilities, movable partitions, width of doors and corridors, offices, and communication aids. (MLH)

After a short historical background, sources of information on reactive chemical hazards are discussed, along with reasons why these sources are not being tapped, particularly in academic laboratories, and some underlying principles. (BB)
