This article presents a systematic eclectic model for organizational change. It is a proactive model in which the change agent defines goals, assesses needs, and reaches out in an active, purposeful way to intervene in the target system. Paper prepared for the Chicago, 1975 Convention of the American Psychological Association. (Author/BP)

Describes the differential equation solution to the mechanics problem of the motion of a free mass subject to a harmonic force which can also be illustrated by a simple analogue computer. (SL)

The lesson for junior high and secondary social studies classes illustrates the effects of a breakdown in the functioning of one key system in an interdependent network. Based on an airline strike, the activity involves students in identifying the subsystems affected by the strike, devising solutions, and writing business reports about the…

According to the learned helplessness hypothesis, the learning impairment typically displayed by subjects previously given insoluble problems results from the real learning of response-outcome independence. This learning is represented as a belief in helplessness that interferes with the subsequent acquisition of adaptive responses. Two…

Discusses the social work intake study as a guide to purposeful intervention, with emphasis on a systems perspective, recognition of the network of social roles, social interaction and cultural factors. Suggests a conceptual scheme for the organization of an intake study, with data related to client's motivation, capacity and opportunity. (BF)

Suggestions for improving problem-solving skills of first-grade students are made after the results of five studies of addition and subtraction story problems are presented. (JT)

Provides additional data to explain the reverse effects of rewards on task performances for training problem-solving skills in fourth-graders. (RL)

The discriminative learning and transfer of compound and component problems were assessed in retarded subjects at two levels of intelligence. (Author/SB)

Discusses different roles the problem statement can play in inquiry and some resulting classroom implications. (SL)

The retreat at the University of California in Los Angeles provides an environment completely away from the bookstore where major issues can be addressed at length without interruption. For two days focus is on store policies, goals, personnel requirements, budgets, review of the previous year, upcoming schedule and events. (LBH)

A series of interesting mathematical applications for the greatest integer function are presented. (JT)

Reviews the application of population balance mathematical treatment to transfer operations in chemical engineering. (SL)

Examples of possible methods for unobtrusively evaluating student progress through real problem solving outcomes without formal testing are illustrated. These methods include the use of interviews, artifacts, observations, I learned statements, checklists, flow of discussion charts, and self-awareness exercises. (MN)

Emphasis is placed on motivating children in problem solving situations by choosing effective questions and attractive unusual materials, considering the ability and frustration level of each child, and by utilizing the help and advice that is available to a teacher. (MN)

Solves the quantum mechanical problem of the bound states corresponding to a sum of several delta-shell potentials. (SL)
