Not all demonstrations involve using exciting visual displays of one or a series of scientific principles. Demonstrations can be as simple as showing the interrelationship between scientific concepts or principles using concept maps. Concepts maps are tools that help people conceptualize and remember a conglomeration of facts making up complex…

In guided design, students are led through the process of solving open-ended problems in "slow motion." Steps in the decision making involved in and examples of guided design projects in a physical science course are outlined and discussed. Comments on student evaluation of the course are included. (JN)

Summarizes research that contrasts the approaches and attitudes of successful and unsuccessful problem solvers. Supplies a categorized list of problem solver characteristics. (RT)

Considers research concentrating on the correlation between knowledge structure and learning. Suggests implications of this research to classroom teaching. Cites characteristics of unsuccessful and successful problem solvers. (RT)

Describes two library-lab exercises the authors have incorporated into their college chemistry course. The first exercise introduces students to scientific information and familiarizes them with the tools for accessing it. The second provides a framework for evaluating the reliability of that information and addresses the criteria that should be…

Discusses science education reform and changes in teaching and learning processes. Compares higher order cognitive skills to lower order cognitive skills in learning, and gives rationales for advocating higher order cognitive skills. (Contains 38 references.) (YDS)

The time and effort spent during the first days of a new semester are key to the success of the class that lies ahead. What happens during these first days can set a tone that inspires students to work actively and cooperatively to achieve success in the new semester, or to sit back and assume a "here we go again" attitude. In this article, the…

Discussion of changes in science education and scientific literacy is presented in the form of a dialog between the author and his alter ego. Structure of science, myths, facts, methods, and critical rationality are considered. Suggests that scientific principles once considered basic and unchanging are giving way to critical thinking. (DH)

Discusses guided design teaching method, applications in secondary/higher education, and the formation of a center to foster guided design as a viable instructional strategy. Guided design course activities are organized around the solution of open-ended problems to provide for the systematic development of decision-making skills. (Author/JN)

Discusses curriculum reforms and appropriate teaching methods for adult learners. Explains a curricular material called "LifeLines Online" which was developed for two-year college faculty to test problem-based curricular materials. Presents a scenario on an alternative way of teaching ecology with Investigative Cased-Based Learning…

Reviews recent research on problem solving, summarizing differences between problem-solving styles of novices and experts. Also describes a text by Daniel Solow ("How to Read and Do Proofs"). Includes chapter titles for the text useful for students who wish to improve their understanding of mathematical reasoning. (JM)
