Describes how the outdated language lab at Houston Baptist University was renovated and updated. Discusses the university's language internship program which grew out of the renovation. (EKN)

In a five-year study, second-year human physiology students were grouped for laboratory according to previous physiology and laboratory experience. No significant differences in course or board examination performance were found, though correlations were found between predental grade-point averages and grouping. (MSE)

Describes a method of staining that makes details clear and dispenses with the time-consuming use of chemicals. The Rheinberg differential color illumination, (or optical staining) is strikingly beautiful and is especially useful with living or nonliving unstained, transparent specimens. Color photographs of sample specimens are included.…

Suggests alternatives for benzene, carbon tetrachloride, and chloroform and offers safety precautions when these solvents must be used. (JN)

Two laboratory procedures in experimental chemotaxonomy are outlined for determining the presence of betalains in genera representing different plant families. A list of materials and equipment needed is provided. (DC)

For architecture students, a laboratory is seen as the most natural and productive way of learning about building construction. An introductory construction course at MIT is described that includes lectures, assigned readings, homework exercises, field trips to construction sites, and a weekly laboratory for hands-on experience. (MLW)

Addresses the problems involved in meeting diverse student needs within the classroom. Encourages the use of computer-managed education (CME) to facilitate the record-keeping and decision-making involved in instruction. Explains the use of a CME system in Seattle Community College's mathematics laboratory. Concludes that CME increases…

Described is a rock encyclopedia combining rock sample sets and encyclopedic word and picture entries which can be used as a realistic information resource for independent study or as a part of a course. (JT)

Describes modification of a gas viscometer to produce a low cost instrument with high precision and safe design. Three tungsten electrodes are mounted in the viscometer using graded glass seals and a ball trap is inserted between mercury reservoir and all external stopcocks. Also describes modifications in experimental procedures. (Author/JN)

Describes an experiment in which parameters from an "ab-initio" potential are used to calculate vibrational-rotational energy levels and construct a "stick spectrum" for the overtone emission of the hydroxyl radical. Provides background information on ab-initio spectrum, experimental procedures, and analysis of data. (Author/JN)

Gives history of use of language laboratories in second-language learning and suggests ways to make time spent by language students in the language laboratory more worthwhile. Claims technological advancement needs effective hardware combined with an understanding of how students learn languages. (Author/BK)

Describes a three-hour liquid chromatography experiment involving rapid separation of colored compounds in glass columns packed with a nonpolar absorbent. Includes apparatus design, sample preparation, experimental procedures, and advantages for this determination. (SK)

This article presents a discussion of the HMI's National Secondary Survey in England during 1975-1978, emphasizing the status of science in the last two years of compulsory education. (SA)

Presented is an expression of opinion on the use of the discovery method in secondary school chemistry classes. The author believes that general rules (lemmas) should be given to students and then they should attempt to disprove the lemmas by observation of experiments. (Author/SA)

Provides a gas chromatography experiment that exercises the quantitative technique of standard addition to the analysis for a minor component, methyl salicylate, in a commercial product, "wintergreen rubbing alcohol." (CS)
