Human expert problem-solving in science is defined and used to account for scientific discovery. These ideas are used to describe BACON.5, a machine expert problem solver that discovers scientific laws using data-driver heuristics and "expectations" such as symmetry. Implications of BACON.5 type research for traditional science education…

Discusses the proposition that rarely does an investigation follow the orderly and systematic course suggested by the scientific method. The most vital elements are not the experimental and theoretical tools of science, but human ingenuity and intuition. (BT)

Methods used to investigate problems in the sciences include building-up strategies, insight, and change (or serendipitous discovery). Discusses appropriate learning experiences for the undergraduate science students so they are more likely to benefit from the second method of scientific discovery as they make a career in their chosen field. (JN)

Reported is an examination of the effects of a newly devised science course upon the logical thought processes of college freshmen. Five tasks designed to determine whether the student did thinking logically when presented with problems of conservation of volume, reversible operations, reconciliation of irrelevant variables, and elimination of…

Discusses the development and use of flowcharts to involve students in the major stages of experimental design and hypothesizing. The progress of stages attempts to simplify the complexity involved during problem-solving in science investigations. Several illustrative flowcharts are included. (JN)

Discusses an experiment designed to give students a feel for the way in which theoretical models evolve. Students are given a system unknown to them and asked to develop a consistent model which fully explains all their observations on the system. (Author/GA)

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)

Reported is a study demonstrating the effects of acknowledgment of success as related to self-concept, problem solving behavior, or science concept development of seventh-grade students. Forty-nine students were randomly assigned to either the experimental group (those who received acknowledgment of successful autonomous discovery) or the control…

The Young Scholars' Program of the National Science Foundation is designed to stimulate and extend the interests in science and mathematics of students entering grades 7 through 12. An additional goal of the program is to encourage them to investigate and pursue careers in science, mathematics, engineering, and technology. The program strongly…

Reported is a study to identify various methods of conducting laboratory programs of experimental inquiry into problems of physics and to determine the effects on performance test scores of three groups of students (elementary education majors). The curricula programs developed were: (1) a laboratory curriculum of self-directed programs of…

Presents a definition of problem solving and discusses process and stages. An outline is given of particular uses of problem-solving networks. (SA)

Explains cognitive basis for change in science paradigms using Watson-Crick DNA model to illustrate concepts of "normal" versus "revolutionary" science. Examines these concepts in light of teacher preception of science, and discusses implications for the practice of science education. (JM)

The game "Pythagoras" is an adaptation of the tangram puzzle. Describes the process of finding all the possible convex polygons with seven sides to prove that the solution to a given puzzle shape of seven sides difficult to find was not possible. (MDH)

The Invent America program addresses the need to provide K-8 students with opportunities to learn critical and creative thinking skills through the process of inventing. Students apply problem-solving skills as they turn their own creative ideas into inventions. It is an effort to integrate the curriculum, help students synthesize knowledge, and…
