Uses the Dresden and Feiock quantum mechanical Kac ring pedagogical model to illustrate formal results and approximation limitations of nonequilibrium statistical mechanics. (SL)

The author gives a method for involving students in developing and verifying elementary number theory hypotheses by studying areas and perimeters of primitive pythagorean triangles. (MN)

Describes the rise of the systematic method of tackling problems of multiple equilibria to calculate the complete titration curves for acids and bases. (SL)

The author provides a brief view of issues and developments in the field of problem solving in the light of progress made as well as implications for the future. (MN)

The opportunity for students to develop formulas that involve tangent lines to a circle and the Pythagorean Theorem and to use approximation and common sense is provided in a suggested distance-to-horizon problem. (MN)

Reviews the mathematical properties of algorithms and problems which can not be resolved by present methods in mathematics. (SL)

In this study, hypothesis probe techniques were used to provide trial-to-trial monitoring of second and third grade children's use of feedback. (SB)

Students (233) in five Israeli high schools were tested to determine the relationship of IQ and achievement, attitudes, and manipulative and observational skills in chemistry. Students indicating a desire to pursue science study were found to differ signicantly their non-science oriented couterparts only on cognitive ability measures. (CP)

The extended school year is presented as an educational alternative to help deter juvenile delinquency, the argument being that youth engaged in formal school environments are less apt to be inclined toward crime. (JC)

This is the second in a series of articles on using mathematical techniques from history to provide an interesting way for middle graders to practice math. (Editor)

A study involving 10 educable and 10 trainable mentally retarded adolescents indicated that levels of intellectual functioning influenced patterns of autonomic activation as measured by magnitude of the galvanic skin response. (CL)

Schematically depicts the variety of uses the mole concept has for 0-level chemistry. (CP)

In a course, Developing Creativity in Teaching, graduate students, many of them experienced teachers of varied subjects in junior and senior high school, practiced some methods which facilitate creative learning. (Author)

Believes educational research needs to move much closer to where national policy decisions are being made. (Editor)
