This document is an English-language abstract (approximately 1,500 words) of a Bulgarian study of six-year-old schoolchildren. Data gathered in a number of countries where children are enrolled at school at the age of six is a sound basis for analytical study; in nations where the enrollment age is seven, such as Bulgaria and the USSR, children's…

This book contains seventeen thumb-nail sketches of schools in Europe, the United States, Asia, Britain, and Australia, as they appeared in the eye of the author as a professional educator and a journalist while travelling around the world. The author considers the schools described to be good schools, and not necessarily the 17 best schools in…

In this experiment designed to trace the development of rivalry in Anglo American and rural Mexican children, rivalry (behavior intended to lower the outcomes of a peer) was measured by 4 choice conditions wherein the rivalrous alternative in all conditions was the choice that left fewer rewards (marbles) to the chooser's peer. After all choices…

This volume is one of the series for the Chemical Technician Curriculum Project (ChemTeC) of the American Chemical Society funded by the National Science Foundation. It consists of discussions, exercises, and experiments on the following topics: ion exchange, electrphoresis, dialysis, electrochemistry, corrosion, electrolytic cells, coulometry,…

In his criticism of existing educational institutions, the author calls for a reform not only of educational institutions, but also of the underlying presumptions of society about the purpose and value of education in general. He explores alternatives to formal schooling, examines the assumption on which our system of universal compulsory…

This vocational physics individualized student instructional module on thermometers consists of the three units: Temperature and heat, expansion thermometers, and electrical thermometers. Designed with a laboratory orientation, experiments are included on linear expansion; making a bimetallic thermometer, a liquid-in-gas thermometer, and a gas…

Indicates how the gas laws can be derived and taught to high school and college physical science classes by using the guided-discovery method. (LS)

Presents a list of Biology-A level projects submitted for the Oxford and Cambridge Board examination by pupils of Uppingham School in the United Kingdom. (HM)

The Parents and Children Project, an experiment to provide an inexpensive and effective educational program to rural areas in Chile, is summarized. Using community resources, parent volunteers, and a part-time staff, the project focuses directly on the education of preschool children. (JK)

Describes simple-to-construct instructional aids to be used in providing an intuitive approach to acceleration. Introductory mechanics involving velocity, distance and acceleration are discussed. (CP)

Discusses the range of wavelengths of the electromagnetic spectrum considered to be the visible portion. Describes a demonstration designed to help students understand the relation between the wavelength measurements on a spectrophotometer such as the Spectronic 20 and the actual colors of light being used. (TW)

Explains: (1) use of piezoelectric film (connected to power supply and oscilloscope) to reveal force-versus-time curves of bouncing balls; (2) use of bound wood splints or meter sticks to illustrate tree or tower stability; and (3) apparatus of co-axial discs with connected linking rods and suspended bobs to simulate waves. (DH)

Discusses electron-loss spectroscopy and the experimentally observed excitation energies in terms of qualitative MO theory. Reviews information on photoelectron spectroscopy and electron transmission spectroscopy and their relation to the occupied and unoccupied orbital levels. Focuses on teaching applications. (ML)

Identifies a technique using methylene blue and glucose to explain a genetically related enzyme shortage causing blue skin in humans. Offers a laser technique to study solubility of silver salts of chloride and chromate. Encourages the use of models and class participation in the study of chirality and enantiomers. (ML)

Describes several experiments that explore the methodology available to the forensic serologist for typing a human bloodstain in the ABH grouping system. Presents ABO blood group of wet blood, Lattes Crust test procedure, and the absorption-elution procedure. Uses outdated blood; equipment requirements are minimal. (ML)
