Hawkins, J.; And Others – Developmental Psychology, 1984
Examines the relationship between development of logical processes required in deductive reasoning and their use by preschoolers, also considering possible explanations for children's deductive reasoning. The relationship of problem content to real-world knowledge and the sequence of presentation of problem types were found to affect the display…

Casey, M. Beth – Developmental Psychology, 1986
Experiment 1 examined the position that mirror-image confusions reflect an inability among three- to five-year-olds to determine whether their performance level differences reflect differences among nonreaders already attending and those not yet attending to reading cues. Experiment 2 examined the Experiment 1 four- and five-year-olds, identified…

Beineke, Lowell W. – College Mathematics Journal, 1989
Explored are various aspects of drawing graphs on surfaces. The Euler's formula, Kuratowski's theorem and the drawing of graphs in the plane with as few crossings as possible are discussed. Some applications including embedding of graphs and coloring of maps are included. (YP)

Gliner, Gail S. – School Science and Mathematics, 1989
Examines the students' understanding of mathematical structure and the relationship between problem solving and the identification of the structure in 13 word problems. Multidimensional scaling and hierarchical cluster analysis were used to assess how subjects organized word problems in their minds. (YP)

Garrett, Roger M. – Research in Science and Technological Education, 1989
Reviewed are 15 studies on cognitive style and problem solving in science education. The effects of problem context, problem type, and three kinds of cognitive style on subjects' abilities to encounter and solve problems are investigated. Three protocols of the subjects' encountering activities are provided. (YP)

Stacey, Kaye – Educational Studies in Mathematics, 1989
Explored are responses of students aged 9 to 13 to linear generalizing problems from both a technical and strategic point of view. The methods commonly used were the same in all age groups and across all three questions, although some students choosing each model varied. (YP)

Puchalska, Ewa; Semadeni, Zbigniew – For the Learning of Mathematics, 1987
Describes an exploratory investigation of how children reacted to problems with missing, surplus or contradictory data. It was found that the majority of children gave unsatisfactory answers to such problems. (PK)
