This study describes the relationship of two cognitive variables, logical thinking and disembedding ability, to learners' abilities to make conceptual shifts from less acceptable to more acceptable conceptual understandings of a physical phenomenon. The difference in the logical thinking and disembedding ability of students who exhibited different…

A student researcher at a nonprofit, university-based family center for learning-disabled and underachieving students designed and implemented a 7-week practicum intervention meant to improve the ability of four first and second grade level students to use reasoning skills. Piagetian theory regarding expected levels of cognitive development was…

This paper reviews some literature on the emergence of formal reasoning and reports a study of reasoning performance of 213 middle grade students in relationship to grade level and chronological age. While a number of large-scale studies have indicated that formal reasoning emerges in a regular progression across age ranges and grade levels, few…

This study investigated the flexibility of 16 supervisors in implementing a developmental approach to supervisor-supervisee interaction during the postobservation conference. Specific objectives included determining: (1) if supervisors' diagnoses of supervisees' conceptual levels (CL) agreed with the Paragraph Completion Method (PCM) measurement…

Systematic cognitive development, through planned experiences in the context of course work, should be a component of teacher education programs, together with opportunities to apply that learning in practicum settings. Training in cognitive skills (analysis of error, comparison and contrast, categorization, identifying relationships among…

This research study was conducted to investigate the interactions of specific student aptitudes with their ability to solve chemistry problems of varying structure and information. Fourteen classroom quizzes were validated and a number of in-task variables were identified for analysis. These variables included: the nature of information given…

Our linguistic environment is so polluted at every level that meaningless, uncritical pseudocommunication is becoming the preferred norm even among the highly educated. (JH)

A study was designed to develop an instrument and methodological procedure to assess transitive relations within seriation problems in elementary school children using three criteria: explanations, judgments, and strategies. A secondary analysis to assess transitivity used the three criteria according to whether the children were conservers, in…

This study investigates the pattern of teacher questioning regarding three elements: sequence, student respondent, and cognitive process. The rationale for this type of teaching rests on the claims for teaching students the process of critical (reflective) thinking. In this type of teaching it is necessary to have data before the students. Only…

Based on an address delivered at the annual meeting of the American Political Science Association (Washington, D.C., September 7, 1968). A comment on the article by Robert E. Cleary is included.

A major goal of mathematics teaching is the involvement of students in the personal process of discovering mathematical ideas and formulating problems. The process of an inductive leap followed by a deductive argument is used in mathematics courses at Phillips Exeter Academy (New Hampshire). Mathematical problems are presented in which the givens…

During socialization, individuals begin to understand increasingly broader and more abstract units of personal and social reality. Subjects (N=97) ranging in age from 13 to late middle age completed a linguistic task in which they could impose higher order conceptions on lower order descriptions by identifying different level similarities within…

Thinking-aloud protocols of human problem solvers working on geometry problems are presented and discussed. Protocols were obtained from six individuals working on nine different problems in which constructions were used. Nineteen protocols are presented with annotation and discussion, and other protocols are summarized. The primary purpose of the…

Recent efforts have been made to develop more age-appropriate intelligence measures for the elderly to determine the nature of age differences and changes in adult cognitive development. Spatial and reasoning performances of young, young-old and old-old individuals were compared on traditional versus familiar and presumably more meaningful…

The study involving approximately 300 deaf students entering the National Technical Institute for the Deaf was designed to determine the extent to which four cognitive measures could be reduced in overall length without serious threat of information loss. The measures investigated were the California Reading Comprehension Test, the Mathematical…
