A teacher in a residential program for students with emotional disturbances, and later a consultant with the state education agency, reflects upon his career, reviews the history of education of students with emotional disturbances, expresses concerns about existing educational practices, and offers suggestions for dealing with predicted future…

Describes and analyzes role problems of trainers who conduct conflict-management workshops between Arabs and Jews in Israel. Uses role theory to focus on problems of role ambiguity and role conflict, citing examples of each. Concludes with discussion of consequences of role problems on trainers' performance. (Author/TE)

This article identifies four transfer-of-learning problems experienced by student teachers, describes the collaborative arrangements to overcome these problems in a small elementary education program at Catholic University of America, relates the success and failure of these arrangements, and discusses the nature of the program's continuing…

Presented is a method where a quadratic equation is solved and from its roots the eigenvalues and corresponding eigenvectors are determined immediately. Included are the proposition, the procedure, and comments. (KR)

Discussed is how a separable field extension can play a major role in many treatments of Galois theory. The technique of diagonalizing matrices is used. Included are the introduction, the proofs, theorems, and corollaries. (KR)

Presented are two exercises on the differential geometry of curves. A generalization dealing with smoothness conditions is given that relates the two exercises. Included are the definitions, theorems, propositions, and proofs. (KR)

Presented is a Poisson derivation using explicitly stated assumptions and exact functional equations. The assumptions are homogeneity, independence, and negligibility. Included are the derivations and proofs using L'Hopital's rule for each assumption. (KR)

Explored is an overdetermined system of linear equations to find an appropriate least squares solution. A geometrical interpretation of this solution is given. Included is a least squares point discussion. (KR)

Described is computational geometry which used concepts and results from classical geometry, topology, combinatorics, as well as standard algorithmic techniques such as sorting and searching, graph manipulations, and linear programing. Also included are special techniques and paradigms. (KR)

Described is the idea of set isometry as examples of Euclidean and non-Euclidean metrics. Included are examples in R squared, preliminaries, and extensions. (KR)

Presented are several models that seem to lead to a better understanding of axiomatics by students. These examples are more like real geometry than the usual examples. Included are the theorems, proofs, and graphs of the functions. (KR)

Briefly reviews children's literature on the themes of cooperative learning, community cooperation, interdependence, and putting the social back into social studies. Summarizes three books for primary readers, four for intermediate grades, and three for young adults. Covers a wide variety of cooperative learning situations. (CH)

An overview is presented of the work and theories of three teams of researchers who have focused on cooperative learning. Cooperative learning has become the outstanding example of an educational innovation in which practice is informed by research; the collective leadership of these teams has advanced its use. (JD)

Reported is a study designed to improve problem-solving skills of high school chemistry students. Interpretations of the data are presented. Recommendations for improvement in teaching problem solving in chemistry are proposed. (CW)

Compared in this research was the performance of students on numerical versus conceptual chemistry problems at the introductory college level. Separate analyses were done to compare high and low achievers. It was shown that even the upper group of achievers had difficulty with concept questions. (CW)
