Describes an experiment to measure the thermal conductivity of some gases in an undergraduate physics laboratory using a hot wire method in the pressure range ten to one torr. (HM)

Describes the infrared analysis of geological specimens which can form the basis of a laboratory exercise, allowing some minerals to be identified by "fingerprint" technique. Students can gain insight into the concept of symmetry and environment around an atom. (Author/SA)

Provides guidelines prepared by the National Science Teachers Association for the use and care of invertebrate and vertebrate animals in the classroom. Suggestions are made for conducting experimental and observational studies. (CS)

Describes programs for the gifted: visual and performing arts for secondary students, enrichment for rural elementary students, and a learning center elementary enrichment program. NOTE: includes "INTERARTS: The High School Program for the Talented in the Arts" by Barbara Luehning, "Spice" by Jane V. Salisbury, and "Learning Center Enrichment…

Explains how CTR Wilson cloud chamber experiments can be simulated with simple low-cost apparatus. Described are the Wilson cloud chamber, colour rings, measurement of rings, and the apparatus. (DS)

This study provides experimental evidence that noise intensities typical of those found in vocational education laboratories are detrimental to student performance. As noise intensities increase in the learning environment, the time required to complete assigned tasks increases. (SK)

Describes methods for studying the direct effect of thyroid hormones on the induction of metamorphic change in amphibians. (CS)

Presents a set of experiments that explore variables within the steps of the filtration process. (CS)

Described is a nontraditional approach to the evaluation of laboratory instruction in general physics courses which focuses on the identification of telling questions, key concepts and basic phenomena involved in the experiment, description of the method used, and the results. (DS)

Reports on an experiment designed to evaluate the effects of "slowed speech" on language students' achievements in listening comprehension. Two second semester college level French classes provided the experimental and control groups. Contrary to expectations, pre- and postexperiment tests showed a significant drop in the experimental…

Describes the objectives and format of a mathematics course offered at Carl Sandburg Community College (IL) which supplements classroom experiences with laboratory experiments. Enumerates the educational benefits of the laboratory approach and discusses the students' evaluation of the course and its format. (AYC)

Describes how satellites and other tools of space technology have transformed classical geodesy into the science of space geodynamics. The establishment and the activities of the French Center for Geodynamic and Astronomical Research Studies (CERGA) are also included. (HM)

Describes the Math Learning Center at Palm Beach Junior College which offers 21 courses of study, including all math courses through trigonometry and 11 general education math courses. Examines the implementation process and various program features. (DR)

A research internship program for undergraduate college students is described. The program, which emphasizes "hands on" experiences for women students, is evaluated by the use of a follow-up study of the graduates. (SA)

Tests given over several semesters of university language laboratory work showed that laboratory periods longer than 35 minutes become unproductive because of fatigue. A change of procedure after 30 minutes--such as test exercises--will activate the learners' power of concentration for another 15 minutes. (IFS/WGA)
