Reported is one researcher's efforts to solve a classic mathematical problem called the "sphere packing problem." The historical barriers to solving this geometry problem are discussed. (CW)

Discusses various aspects of artificial intelligence, focusing on three interrelated issues: (1) representation of knowledge, which is roughly the machine equivalent of human memory; (2) control and use of knowledge, which corresponds to human abilities in problem solving and planning; and (3) the acquisition of knowledge, or what humans call…

Presents evidence that the psychological principles that govern the perception of decision problems and evaluation of probabilities and outcomes produce predictable shifts of preference when the same problem is framed in different ways. (Author/SK)

Focuses on human information processes and problem solving. Although a large body of knowledge is prerequisite to acquiring skill, the authors state that knowledge must be indexed by patterns that guide the person in a fraction of a second to relevant parts of the knowledge store. (Author/SA)

Highlights findings from cognitive science which suggest new approaches for science and mathematics instruction, addressing role of naive theories and qualitative understanding of situations in problem-solving. Also considers nature of the learner based on the findings. (JN)

Cites changes to occur on the Medical College Admissions Test to include: a reduction from six to four sections, biology and physics content-specific sections to absorb chemistry, elimination of multiple-choice questions to a problem-solving format, and the inclusion of graded essay questions. (RT)

Traces the history and function of State, Operator, And Result (SOAR), a general-purpose artificial intelligence program for solving problems. The SOAR can "chunk" the result of a subgoal and learn from previous experiences. The SOAR could be applied to various expert systems. (YP)

Describes the current states of artificial intelligence in education and assesses probable future developments and problems. Reviews the National Science Foundation's strategy to aid research in the area. (JM)
