Explores the role that symbolic-graphical calculators can play in the current calls for reform in the mathematics curriculum. Discusses symbolic calculators and graphing calculators in relation to problem solving, computational skills, and mathematics instruction. (MDH)

A model for the development of scientific reasoning in adolescents was formulated largely upon the basis of Piagetian theory. Included as potential determinants of scientific reasoning were experience, age, locus of control, field independence-dependence (FID), rigidity/flexibility, intelligence quotient (IQ), and sex. Causal relationships between…

The purpose of this study was to investigate the relationship between the achievement of some abstract concepts in "molecular genetics" and prior knowledge, formal reasoning ability, and sex. The major findings of the study were: (1) prior knowledge had a high significant correlation with the achievement of abstract concepts; (2) the…

In this seventh-grade language unit, the study of semantics is introduced by an examination of the relationships between words and their referents, particularly in terms of changes of meaning and degrees of abstraction. Classroom activities are suggested to help students become aware of "language liveliness" and the processes of…

The difficulties experienced by deaf parents' hearing children (n=10) as they approached puberty were studied and compensatory education programs sought for them through residential and regular schools. The children exhibited conversational difficulties, memory problems, reasoning difficulties, and poor language comprehension. Children's…

Investigated relationship of teachers' cognitive levels and cognitive level demand of textbooks in relation to students capability to learn biology. Based on findings, teaching units were designed to help science teachers acquire skills, use innovative formats of instruction for abstract topics, and develop logical thinking skills through biology…

Evidence from the research literature suggests that a variety of cognitive factors are responsible for chemistry achievement. This investigation examined the role that four cognitive factors, namely, prior knowledge, formal reasoning ability, memory capacity and field independence/dependence, play on achievement in chemistry as measured by tests…

The results of studies that examined the logical reasoning of secondary students in Jamaica are analyzed. A logical reasoning test was administered to 205 Jamaican students in grades 7, 9, and 11. Also analyzed were data collected using the same instrument on three other groups of Jamaican students in grades 7, 8, 9, and 10. As expected, test…
