The experiment tested the hypothesis that the stress experienced by a person who is unable to control aversive stimulation is not a function of lack of control per se, but of the attribution of causality that one makes for failure to exert control. (Editor)

Presents a series of discussions on the general elements of experimental design and the scientific process and relates these elements to the field of communication. (MH)

The validity of various laboratory and field tests of the physical working capacity of college males was investigated. (GW)

Presents six kinds of corrosion and laboratory experiments that demonstrate the chemical reactions that occur in each. Relates studies in corrosion to studies of resource wastefulness. (CS)

Describes a social psychology experiment at the University of New Hampshire involving the use of skits to demonstrate concepts. Findings indicate that students in the experimental group perceived the skits as valuable and interesting. Results are compared with the original hypotheses. (Author/DB)

The purpose of this paper is to present an ethnographic study (Cardoso, 1999) involving six primary school pupils and doing simple experiments with everyday home equipment in the context of learning science. The hands-on science activities were carried out by children with the help of their parents. Results showed that children learnt at home and…

To examine how conceptual knowledge about fraction magnitudes changes as students' learning progresses, 5th and 7th-grade students were asked to solve fraction magnitude problems that entailed finding a fraction between two given fractions and then to evaluate solutions for similar problems that were modeled for them. When the given fractions…

This book provides opportunities for engaging students in scientific investigations, offering a hands-on approach that encourages students to understand science concepts, gives them ways to apply the concepts, and introduces and reinforces the skills they need to become independent investigators. The basic outline and objectives of each section of…

Many aspects of string theory are abstract and difficult for even theoretical physicist to fully comprehend. The activities in this guide are designed to help teachers and students better understand some of the basic concepts underlying particle physics and string theory. A list of additional resources and a glossary are also included. Each…

Noting that a central tenet of the 1996 welfare reform law was that work was the best way to improve the lives of single parents and their children, this fact sheet summarizes research on the impact of parental work on children in families receiving welfare. The fact sheet delineates key research findings from experimental studies of the effects…

Plants provide oxygen, food, shelter, medicine and more for all animals, including humans. In fact, people depend on plants for their very survival just as plants rely on animals! In All About Plant & Animal Interdependency, join aspiring botanists as they discover how plants and animals interrelate. Learn about the constant exchange of gases…

The provisions made by Congress to assist the States in promoting education make up an important chapter in the development of education in the American Commonwealths. Due to the constant demand for information concerning this subject, the National Advisory Committee on Education requested a digest of legislation and literature relating to Federal…

While the new movement in the teaching of physics--the study of the physics of daily life--is the keynote of the recent text-books, yet the laboratory manuals still adhere to the old method, leaving the presentation of material from everyday life to the text-book alone. It is the authors' belief that the manual as well as the text-book should be…

Describes a number of activities, using pennies, which present children with problem-solving opportunities and reinforce some simple science concepts. (JR)
