Examines the problem of determining the minimum center of mass for a can with a varying height of liquid in it. Uses PC SOLVE computer software to graphically represent the problem situation. (MDH)

Reacts to Ohlsson, Ernst, and Rees' paper by initially discussing the costs of methodology that utilizes artificial intelligence (AI) to model cognitive processes. Raises three concerns with the paper: insufficient clarification of the meaning of conceptual versus procedural understanding of base-10 subtraction; realism of the learning model; and…

A study of a team-building workshop demonstrates that all four levels of Donald Kirkpatrick's classic evaluation model could be applied to soft skills training. Results show that such training can be tied to productivity measures and evaluated as a return on investment. (JOW)

The growth of personal autonomy was studies in a reflective, inquiry-oriented teacher education program, analyzing how often beginning teachers displayed critical reflection when their self-directed seminar focused on authority. Findings indicated the nondirective seminar devoted to promoting personal autonomy and collaboration did not meet…

Describes the use of Smalltalk-80, a French programing language, to teach young children to program effectively using object-oriented concepts. Learning processes involving problem solving and programing are examined, the object-oriented environment is discussed, teacher training is described, and future work is suggested. (21 references) (LRW)

Describes the use of expert systems in elementary school classes that focused on developing thinking skills and independent learning. Expert systems as tools, tutors, and tutees are discussed; differences in learning styles are considered; problem-solving skills are addressed; and uses of expert systems in science and social studies are described.…

Presented is the idea that art can be used to present early concepts of geometry, including the notion of the infinite. Discussed is the symbiosis that exists between the artistic and mathematical views of points, lines, and planes. Geometric models in art and using art in the classroom are discussed. (KR)

Presented is the best understanding of the flaw discovered in the optics of the Hubble Space Telescope and the possible solutions to the problems. The spherical aberration in the telescope's mirror and its effect on the quality of the telescope's imaging ability is discussed. (CW)

Presented is a way to provide students with a review and an appreciation of the versatility of pointers in data structures by improvising with binary trees. Examples are described using the Pascal programing language. (KR)

Discussed are the possible uses of spreadsheets in the undergraduate curriculum in chemical engineering classes. The advantages and flexibility of spreadsheets, spreadsheet instruction, graphing capabilities, assignment examples, and conclusions are described. (KR)

Examines strategic differences between more and less competent novices in story-sorting, problem-solving tasks by comparing two Hong Kong primary school teachers, two competent and two less competent secondary students on problem-solving tasks. Indicates subjects used a wide variety of solution strategies. Suggests that success depended on how…

Presents findings of a study involving 34 undergraduates, examining how exposure to different belief structures might change an individual's belief structure. Suggests that, when the individual is high in public self-conscious, their belief structures will change after encountering different belief structures. Implies that public posturing can…

The article presents guidelines for creating a thinking environment for children at home. Teachers today have little time to emphasize thinking skills, so parents must make their homes more thoughtful places by encouraging questions, open-mindedness, discussion, and practice time using simple everyday experiences to teach critical thinking and…

Argues that educational computing is a discipline and discusses issues that need to be addressed in this discipline, including similarities with experimental psychology; networks and integrated learning systems; problem-solving software versus domain-specific software; computer labs versus classroom integration; software quality; computer equity;…

Included are probability models for various strategies that contestants on the television game show, "Let's-Make-a-Deal," might use when given the option to stick with their original choice of three unopened doors or switch to the unopened door after one of the other two doors has been opened. (JJK)
