Summarizes the results of a 1969 experiment survey made for learning the impact of special publications and the trend of experimentation in colleges. Describes some new or modified apparatus that has appared since the 1956 survey. (GS)

Presented is a pilot study focusing attention on problems of deteriorating physical plants and inadequate/obsolete equipment contributing to the current crisis in engineering education. Data are reported from a survey instrument (included in an appendix) from 26 colleges/universities, representing 168 programs out of a national total of 1212…

Describes the construction of a model suitable for demonstrating the principles of refrigeration in secondary science classes. (JR)

Describes construction of an inexpensive wind tunnel and a water manometer; experiments with model airplanes; and the calibration of the manometer and its use to measure wind velocity and lift on an airplane wing. Additional experiments with an electric fan are suggested. Diagrams are included. (GH)

A capacitor is discharged to generate an acoustical pulse and start a digital counter which is stopped by a microphone. Differences are accurately measured by positioning the sensing microphone on an optical bench. Results are discussed and extended experiments are suggested. The sources of some components are given. (GH)

Describes a cell that is free-standing and facilitates the collection of evolved gases in test-tubes. A similar cell is used to demonstrate the Kellner-Solvay electrolysis of brine. (GS)

DESIGNED FOR TEACHERS AND ADMINISTRATORS, THIS WORK SHEET PROVIDES GENERAL AND SPECIFIC INFORMATION ABOUT THE PHILOSOPHY, TYPES, AND USES OF LANGUAGE LABORATORIES IN SECONDARY SCHOOL LANGUAGE PROGRAMS.

WAYS ARE SUGGESTED FOR USING THE "AUDIO ADAPTER" IN THE LANGUAGE LABORATORY TO HELP DEVELOP THE SPEAKING SKILLS OF ADVANCED STUDENTS. A DETAILED DESCRIPTION OF THE AUDIO ADAPTER, A TYPE OF JUNCTION BOX, IS GIVEN, ALONG WITH INSTRUCTIONS FOR CONSTRUCTING IT. FOUR TYPES OF SPEAKING PRACTICE ARE DESCRIBED--(1) FREE CONVERSATION, WITH STUDENTS WORKING…

TRUE PROFESSIONAL STATUS FOR A LABORATORY DIRECTOR, PLUS ADMINISTRATIVE SUPPORT OF SUCH INSTRUCTION, WILL GIVE COLLEGES AND UNIVERSITIES ADEQUATE RETURN FOR THEIR INVESTMENT IN ELECTRONIC EQUIPMENT. BY BEING INVOLVED IN IMPORTANT RESEARCH AND INSTRUCTIONAL ACTIVITIES, THE DIRECTOR OF A LANGUAGE LABORATORY CAN SERVE ALSO TO FREE THE TEACHER AND…

The control and inventory of property items using data processing machines requires a form of numerical description or code which will allow a maximum of description in a minimum of space on the data card. An adaptation of a standard industrial classification system is given to cover any expendable warehouse item or non-expendable piece of…

After a brief history of the development of the language laboratory, the extent, quality, and problems of current laboratory use at the elementary, high school, and college level is discussed, as is the relationship between laboratory equipment and teaching methods. Current research is briefly reviewed, and areas for further study are indicated.…

The definition, purposes, and possible uses of the language laboratory are discussed in this booklet. Consideration is given to such related topics as the production of materials, the student's task in the laboratory, the planning and supervision of the laboratory, and the problems and future of the laboratory. The second half of the booklet…

The scope of facilities required for the conduct of research in health-related sciences is governed by the type of work to be undertaken and the physical characteristics of the building, and can range from a simple office to extremely complex laboratories with numerous utility services. Every laboratory should be designed to accommodate--(1) all…

The hypothesis that students will express no preference between carrels and open table type of accommodation in a language laboratory was tested in a four-week study. Two identical rooms, one containing carrels and the other containing open tables, were connected to a single control room and used by 1,080 university students (enrolled in language…
