An explanation of strong base effect demonstrates that deprotonation of a reactant shifts an equilibrium toward reactants in the same way that a deprotonation of a product shifts it towards products. (Author/SA)

This document presents a curriculum base for a particular school system comprised of eight high schools. Its purpose is to provide a conceptual base which encourages flexibility and diversity. The format is based on the conceptual schemes identified in the NSTA publication, Theory Into Action. Included in the publication is the philosophy of the…

Shocked by static? Mixed up about magnets? Curious about currents? Teachers can get past memorizing all those electricity-related formulas, rules, and procedures so they can understand the subject at a level deep enough to teach it with confidence and comfort. Here to help is "Electricity and Magnetism," the fifth title in the award-winning NSTA…

This publication describes a four year, field-based program for the preparation of science teachers. It begins with a paper providing an overview of the current Iowa-UPSTEP model. A follow-up paper elaborates various facets of the model. The model integrates theory with a series of field-based clinical experiences in a four year program, providing…

The simulation of a sampled-data system is described that uses a full parallel hybrid computer. The sampled data system simulated illustrates the proportional-integral-derivative (PID) discrete control of a continuous second-order process representing a stirred-tank. The stirred-tank is simulated using continuous analog components, while PID…

Presented is an overview and model of the proposed curriculum development process in environmental education in Connecticut. Concepts and competencies are identified at each grade level and are designed to facilitate the infusion of environmental education activities within the existing curricula using existing learning resources such as…

Nine years after the National Science Education Standards' release, just how well do science teachers in grades 5 to 8 actually use them to plan content, define improved teaching, and assess real learning? Find out the answers to these key questions in this groundbreaking collection of 15 essays by teachers, researchers, and professors whose…

This activity is designed for secondary school students. The process of constructing a model solar building includes consideration of many fundamental scientific principles, such as the nature of heat, light, electricity, and energy conversion technology. When the model solar building is completed, there are numerous possibilities for the use of…

This publication, a revised edition of ED 081 706, contains a conceptual framework for social studies curriculum development. The social science disciplines--anthropology, economics, geography, history, political science, psychology, and sociology--are considered resources for providing the key concepts, insights, and methods of inquiry enabling…

This model is useful in identifying specific learning problems and in providing techniques for the teacher to motivate and teach students at all levels. What it is and how it can be used are discussed, illustrated by specific strategies for geometry and science. (MNS)

This paper presents a sketch of the characteristics of a group of professionals whose work involves helping others. The author attempts to define individuals who are concerned primarily with the helping professions, and to outline some of the attributes unique to them. He tries to identify factors distinguishing those who are successful from those…

This guide for teacher inservice training is focused on the concept of Ekistics--the study of man in his environment. The strategies presented are based on generic inservice culminating in a management planning model, purposefully generic to all inservice and intended to add support to the personnel who would be designing inservice. The steps to…

The decision support system (DSS) environment, the functional requirements of a DSS, and the architectural requirements of the computer systems and communications network necessary to support a DSS are discussed. Changes in the computing environment that are necessary to implement decision support systems are suggested. (Author/MLW)

Describes the development of the Chicago Museum of Science and Industry and its exhibits, which rely on participatory techniques in furthering public understanding of science and technology. Two thousand exhibit units cover seventy-five diverse fields, and the museum's educational program comprises twenty scientific demonstrations. Special…

The model stresses interactions among specific combinations of cognitive task requirements, learner characteristics, and instructional treatment properties, in a manner analogous to the aptitude-treatment interaction (ATI) model. "Supplantation" is the provision of overt assistance to learners in performing a specific process required by…
