This presentation of suggested layouts and specifications has been prepared to be of service to school boards, architects, teachers, and administrators who are planning new schools or making renovations to existing structures. The recommendations cover many of the facilities that have been observed in schools throughout the province, and which…

An audiotutorial approach to problem-solving in college chemistry relying upon audio tapes is available. The program is designed to increase the teacher's effectiveness by providing individualized attention to student difficulties related to problem-solving. Problem solutions are recorded on audio tapes (designed for use with Sony TC-160 cassettes…

Computer programs which teach concepts and processes related to biology, earth science, and chemistry are presented. The seven biology problems deal with aspects of genetics, evolution and natural selection, gametogenesis, enzymes, photosynthesis, and the transport of material across a membrane. Four earth science problems concern climates, the…

This self-study program for high-school level contains lessons on: Atomic Structure and Valence, Chemical Bonding, The Table of Elements, and Electrolysis. Each of the lessons concludes with a Mastery Test to be completed by the student. (DB)

The United States Training and Employment Service General Aptitude Test Battery (GATB), first published in 1947, has been included in a continuing program of research to validate the tests against success in many different occupations. The GATB consists of 12 tests which measure nine aptitudes: General Learning Ability; Verbal Aptitude; Numerical…

Lists 40 things to do to have a safer chemistry laboratory. Discusses the evolution of these guidelines for schools from safety suggestions originally developed by industry. Categorizes the 40 steps into those requiring minimal cost and those requiring moderate expense. (TW)

Compares the amount of research being published by personnel from 37 undergraduate institutions of higher learning during the 1970's with the amount published from 1980-1985. Lists the number of student co-authored publications in chemistry from the leading 11 institutions for 1980-1985. (TW)

Discusses the properties of carbon dioxide in its solid "dry ice" stage. Suggests several demonstrations and experiments that use dry ice to illustrate Avogadro's Law, Boyle's Law, Kinetic-Molecular Theory, and the effects of dry ice in basic solution, in limewater, and in acetone. (TW)

Proposes that preparative chemistry is an important and integral part of chemistry as a whole, and an excellent way to introduce students to descriptive chemistry. Provides an outline for students to follow for converting and transforming salts. Suggests a set of general guidelines for studying anion and cation transformations. (TW)

Discusses the need to consider students' pre-existing conceptual schemes when teaching chemistry. Reports on a study done in Spain which indicates that the existence of adolescents preconceptions about gases is important to consider when teaching the principles of conservation of substance, mass, and weight. (TW)

Discusses the need to develop laboratory practical examinations in chemistry which attempt to measure students higher order thinking skills and conceptual understanding rather than simply their laboratory skills. Examples of examination questions being used in general chemistry laboratory courses at the State University of New York at Cortland are…

Describes a chemistry experiment where an alkaline ice-cold permanganate solution is reduced by adding dropwise a cold diluted hydrogen peroxide solution. Outlines the course of the reduction through the various oxidation states of manganese with their characteristic colors. (TW)

Outlines an approach to chemistry experiments designed to help students appreciate the importance of each step in an experimental procedure. Describes an experiment involving Charles's Law to illustrate this idea. (TW)

Questions the use of the Reactivity Selectivity Principle (RSP) by teachers and authors of texts in discussing organic reaction mechanisms. Provides some applications and failures of the use of the RSP, reviews some quantitative aspects of the RSP, and discusses some of the rationalization of the RSP failures. (TW)

Discusses the classification of binary oxides as acidic, basic, or amphoteric. Demonstrates how a numerical scale for acidity/basicity of binary oxides can be constructed using thermochemical data for oxoacid salts. Presents the calculations derived from the data that provide the numeric scale values. (TW)
