The basic mechanical functions of the foreign language laboratory described in this report enable utilization of authentic target language, linguistically effective learning devices, visuals, and facilities for monitoring and testing. Brief descriptions of 11 laboratory functions include: (1) isolation (physical, acoustical, and psychological),…

This contrastive listing of the possibilities and problems of the language laboratory is intended for the elementary and secondary school teacher. In this article, the author emphasizes the oral nature of language and the need to treat methods, materials, and machinery as a trinity. (RL)

This paper describes the development and evaluation of self-instructional Spanish course designed to produce an elementary communication skill sufficient to meet conversational and travel requirements. Some 106 lessons, known as AUTOSPAN and organized in seven major sections are described. Two novel pedagogic techniques which simulate live…

Identifies specific science skill activities and discusses how they can be enhanced using the microcomputer in a laboratory setting. Highlights the benefits, advantages, and applications of microcomputers in physics laboratories. (ML)

Describes a field trip activity to measure changes in elevation across the dunes of a barrier beach, measure wind velocity along the transect line, and observe the distribution of ground cover in the study area. Discusses equipment, materials, procedures and follow-up activities for each study. (CW)

Lists five experiments or demonstrations involving hypodermic syringes. The titles of experiments are Boyle's Law, Charles' Law, Atmospheric Pressure, Expansion of Gases, and Boiling at Reduced Pressure. Provides a list of materials, the typical data, and graphs where appropriate. (YP)

Describes an experiment that is to be performed midway in the first semester of an undergraduate organic chemistry laboratory coinciding with the students' introduction to cis-trans isomerism in the study of alkenes. Discusses the apparatus, materials, experimental procedure, historical significance, and results. (CW)

Describes the absorption and containment (AC) approach to laboratory chemical-spill cleanup. Discusses currently recommended chemical-spill cleanup procedures and evaluates commercially available cleanup materials. Promotes the use of the AC method in terms of its relative safety, availability of materials, and ease of instruction. (TW)

In preparing this volume, every effort has been made to ensure accuracy, the most recent authorities have been consulted, and it is believed that a faithful view is presented of the various sciences embraced, as far as they are at present developed. It is the intention of the author to keep his book up to the times by constant revision, and to…

Presented are four activities which are designed to familiarize children with the multiple uses of computers and help them learn about heat and temperature using temperature probes. Included are the tempering effect of water, heat capacity, caloric content of foods, and weather. Hardware and software are discussed. (CW)

Presented is an activity which uses the annual process of abscission and leaf drop to illustrate all of the phases of the scientific method. Procedures, hypothesis formation, and typical results and conclusions are discussed. Alternative activities are suggested. (CW)

Discussed is the use of volunteers to teach an astronomy laboratory course. Amateur astronomy groups were recruited to help teach this course. Advantages of using volunteers are listed. A list of student field experiences is included. (KR)

Described is a means of logging data from remote sensors in data files and then transferring the data to a spreadsheet for processing. The presentation of the data in tabular or graphical form is discussed. An example using temperature data from a model house is provided. (Author/CW)

Described is a simulation program designed to teach the geology of oil exploration in a game format. Discussed are information and tools provided, information management, data sets, and availability of the program. (CW)
