Carries on from an article about the context for assessment of problem solving skills. Describes other forms of evidence in problem solving skill besides the options given in the previous article. Lists eight forms of evidence related more directly to the problem solving process. Analyzes the relationship among some of these suggested forms of…

The paper critically appraises the concept-learning and developmental perspectives in science education to show that Pascual-Leone's Theory of Constructive Operators leads to a progressive problem-shift between Piaget's epistemic subject and Pascual-Leone's metasubject. (SM)

Describes the specifics of instruction in thermodynamics using a problem-solving technique introduced in a previous issue of this journal. (CS)

Addresses the principles and problems associated with the use of significant figures. Explains uncertainty, the meaning of significant figures, the Simple Rule, the Three Rule, and the 1-5 Rule. Also provides examples of the Rules. (ML)

Mathematics plays an exceptionally important role in biological education and the history of biology. Ten equations and descriptions of their historical importance are presented to draw students' and faculty's attention to mathematical models that have been intrinsic to many of the significant discoveries in biology in the 20th century. Each…

High school physics, if taught properly, should be accessible to 50% of students rather than the currently estimated 20% of students. Suggests changes that need to be made in course format, including giving plenty of problem-solving help, improving high school texts to conform to principles of learning, and designing a course so that all can…

Describes a variety of projects that were used in a summer program for gifted high school students to help teach biotechnical concepts and applications. Presents six projects utilizing algae as tool for solving problems. Also presents five production-oriented projects with hydroponics and fermentation as research and development themes. (PR)

Reports on the Seventh Annual Conference on Chemical Education which explored the assumption that science courses focus too much on the product of science and not enough on the process. Problem solving was examined as a possible route toward developing the necessary critical-thinking skills. Covers the keynote address, Problems versus Exercises,…

Presents an interview with Erno Rubik, creator of "Rubik's Cube." Included are comments about the creation of the cube and the role of the cube in educating people, especially in problem-solving activities. (JN)

Reports on the winning tool creations by 1,300 fourth-, fifth-, and sixth-grade students in the 1997 Craftsman/NSTA Young Inventors Awards Program. Students had to use mechanical and science process skills to design and build tools to meet their needs in solving a problem. The winning entry was a calibrated angle and depth scissors. (AIM)

Presented are four information bulletins produced by the ERIC Clearinghouse for Science, Mathematics, and Environmental Education in 1981. Bulletin 1 is concerned with various pieces of information related to citizen participation activities in which citizens interact with each other to get a response from the government regarding governmental…

Experienced Physicists solve simple textbook problems differently from beginning students. This paper describes these differences using a computer-implemented model that "learns." The research is set in the the context of modern computer-processing psychology, and is related to other work relevant to help people know and learn…

Ten papers are presented as a part of the celebration of the twentieth anniversary of the Science and Mathematics Teaching Center at Michigan State University, East Lansing. Titles of the papers are: (1) "Science and Mathematics Education: Retrospect and Prospect"; (2) "Developing Scientific and Mathematical Literacy Among Elementary and Secondary…

Presents examples that recognize young children's technological prowess and support the case for including two significant curriculum perspectives: an intellectual-processes perspective and a social-expression perspective. Contains 34 references. (Author/PVD)

Explains the difference between everyday thinking and academic thinking. Maintains that children who experience academic learning problems may rely too much on everyday thinking skills. Relates examples of this problem in reading, mathematics, and science. (JDH)
