This article reports on the experiences and perceptions of K-12 teachers as they engaged in a participatory action research (PAR) project, "Science Across the Curriculum." Although the experiences and professional learning of two of the project participants are highlighted, the challenges that all participants experienced as they conceptualized…

Considered are the main elements of computational chemistry problems and how these elements can be used to formulate the problems mathematically. Techniques that are useful in devising an appropriate solution are also considered. (Author/TG)

College students identified air quality, world hunger, and war technology as the most important of 12 global problems (presented to them during a survey) and indicated that problems will become worse by the year 2000. Implications of findings for curriculum and instruction are addressed. (JN)

Presented are two problem exercises involving rapid compression and expansion of ideal gases which illustrate the first and second laws of thermodynamics. The first problem involves the conversion of gravitational energy into heat through mechanical work. The second involves the mutual interaction of two gases through an adiabatic piston. (BT)

Presents part seven of a continuing presentation of exponential functions. Provided is an extension of the part six discussion, exponential population growth, to world population growth. (SL)

Applications of physics concepts related to the activities of dinosaurs are presented. Problems of mass, speed and motion, and sound are discussed. Solutions to the problems are shown. (CW)

This teacher's guide, with accompanying videotape, presents an episode of the NASA SCI Files. In this episode, one of the tree house detectives has had an accident and cannot get into the tree house. Using problem-based learning, the rest of the gang investigates the world of simple machines and physical science and "pull" together to…

A brief overview is given of the part of meteorology which deals with the circulation of the atmosphere. This is followed by eight illustrative application problems for mathematics classes. (MNS)

Outlines various misconceptions about problem-solving (PS) and several strategies to improve intellectual skills and strategies. Also describes the Covington Productive Thinking Program (designed to help develop PS skills) and several lesson problem sets from this series of 15 books. (JN)

Presents a practical problem to students in a junior-level thermodynamics course in which a human body regulates its own internal temperature. This problem can be utilized as well (with modification) in an introductory physics course for life science majors. (HM)

This document is intended as a resource and guide to help teachers integrate a problem-centered approach into their curricula. It outlines the typical components of problem-centered mathematics and science activities, and offers practical suggestions, examples, and resources to assist this endeavor. The first section of this document, "What is…

Two science classroom techniques that can be used in the social studies classroom to motivate students involve puzzling phenomena and relating science to social issues such as over-population, energy, and pollution. (JR)

Presents: (1) a list of ideas for teaching problem-solving; (2) a review of a problem-solving book used in medical education; and (3) a discussion of an approach called problem-based learning. (DH)

Discusses the difference between a generic chemistry problem (one which can be solved using an algorithm) and a harder chemistry problem (one for which there is no algorithm). Encourages teachers to help students recognize these categories of problems so they will be better able to find solutions. (TW)

Presented are the teacher and student editions for six modules designed to teach students how to investigate and evaluate science-related social issues. These modules (each of which includes an introduction, objectives, readings, and activities) focus on: (1) environmental problem solving; (2) preparing to investigate an environmental issue; (3)…
