The Factor Structure of Concrete and Formal Operations: A Confirmation of Piaget.
PDF on ERIC Download full text
Gray, William M.
Piaget has hypothesized that concrete and formal operations can be described by specific logical models. The present study focused on assessing various aspects of four concrete operational groupings and two variations of two formal operational characteristics. Six hundred twenty-two 9-14 year old students participating in the Human Sciences…

Testing Based on Understanding: Implications from Studies of Spatial Ability.
Peer reviewed Peer reviewed
Egan, Dennis E. – Intelligence, 1979
The information-processing approach and results of research on spatial ability are analyzed. Performance consists of a sequence of distinct mental operations that seem general across subjects, and can be individually measured. New interpretations for some classical concepts in psychological testing and procedures for abilities are suggested.…

Theory of Constructions and Set in Problem Solving.
PDF on ERIC Download full text
Greeno, James G.; And Others – 1979
Hierarchically organized knowledge about actions has been postulated to explain planning in problem solving. Perdix, a simulation of problem solving in geometry with schematic planning knowledge, is described. Perdix' planning knowledge enables it to augment the problem space it is given by constructing auxiliary lines. The planning system also…

The Construction and Comparison of Three Related Tests of Formal Reasoning.
Peer reviewed Peer reviewed
Carlson, Gaylen R.; Streitberger, Eric – Science Education, 1983
Compared formal reasoning responses of seventh-and eighth-grade students on three tests of formal reasoning. The three tests differ only in the mode of equipment presentation on identical test items and problems. Tests included three-dimension demonstration (Lawson), two-dimension showing drawings of materials used in three-dimensional test, and…

A Preliminary Report of the Relationship Between Piaget's and Klausmeier's Measures of Children's Cognitive Development. Technical Report No. 426. Reprinted December 1977.
Klausmeier, Herbert J.; And Others – 1976
Piaget's model of children's conceptual learning and development was compared with Klausmeier's Conceptual Learning and Development (CLD) model in a longitudinal study. The CLD model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known…

Third Cross-Sectional Study of Attainment of the Concepts "Equilateral Triangle,""Cutting Tool,""Noun," and "Tree" By Children Age 7 to 17. Technical Report No. 427. Reprinted December 1977.
Klausmeier, Herbert J.; And Others – 1976
The Conceptual Learning and Development (CLD) Model specifies four levels of concept attainment (concrete, identity, classificatory, and formal) and three uses of concepts (problem solving, subordinate-supraordinate, and principles). Longitudinal and cross-sectional studies of concept attainment may be conducted. The results of this study of 300…
