Recommends that tutoring instruction offered in writing centers be at the same level of professional standards and competence as other instruction offered at the two-year college. (AEA)

Describes structured and open-ended evaluation techniques that permit students in a reading center to rate their own reading performance. (FL)

Following a discussion of the role and importance of practical laboratory tests, describes an instrument designed for inquiry-oriented practical examinations. The instrument consists of 21 categories representing different inquiry skills. Examples and illustrative data based on results in biology matriculation examination in Israel are reported.…

Outlines a laboratory procedure which enables students to evaluate the contamination potential of surface impoundments and apply basic principles of hydrogeology to the land disposal of waste material. Includes a list of materials needed and directions for the instructor. (Author/DC)

The author describes and illustrates aids and adaptations for science classes serving severely physically handicapped students. Guidelines are offered on precautions to take, school made aids (such as a trolley), and use of microscopes. (SB)

Summarizes information on the properties of synchrotron radiation and describes laboratories in the United States specializing in this science, including facilities at the National Bureau of Standards, University of Wisconsin, Stanford, and Brookhaven. (CS)

Describes a companion experiment to the experimental study of the di-iodide visible absorption spectrum. Experimental details, interpretation, and data analysis are provided for an analysis of the di-iodide fluorescence excited by a visible laser, using a Raman instrument. (CS)

Background information, procedures, and materials needed are provided for an experiment in which acetone is produced from 2-propanol. The experiment does not use magnetic stirring, avoids the necessity for exhaustive extractions with ether, and produces a 60-percent yield of redistilled acetone within a two-and-one-half-hour laboratory period.…

Background information procedures and results are provided for a diffusion (permeation) experiment using an inexpensive instrument and performed during a single three-hour laboratory period. (JN)

Discusses the practical problems accompanying the teaching of chemistry to visually impaired students, including communication problems, improvement of lecturing, laboratory orientation, and safety considerations. (CS)

Reviews factors specific to hearing impairment, special potential teaching problems and how they may be resolved, and problems involved with lecture and laboratory experiences in chemistry for hearing impaired students. (CS)

In Part I of this two-part article, the author describes the evolution of the Computer Tutor project in Palo Alto, California, and the strategies she incorporated into a successful student-taught computer literacy program. Journal availability: Educational Computer, P.O. Box 535, Cupertino, CA 95015. (Editor/SJL)

Experimental procedures, typical observations, and results for the simultaneous analysis of Fe(III) and Cu(II) in a solution are discussed. The method is based on selective interaction between the two ions and potassium hexacyanoruthenate(II) in acid solution involving no preliminary sample preparations. (Author/JN)

A simple, three-step procedure for synthesizing a dipeptide from its component amino acids is described. The dipeptide synthesized uses inexpensive amino acids having hydrocarbon side-chains and can be observed in E/Z forms by nuclear magnetic resonance spectroscopy. Each step in the synthesis produces white crystalline products using standard…

Provides tips for stimulating interest in high school chemistry while imprinting safe laboratory practice. Suggests safe alternatives to potentially dangerous "magic show" and other chemical reactions. Also suggests that safety education be a prerequisite for certification of secondary school chemistry teachers. (Author/JN)
