Abstract/Description
-
A total of 96 adults (mean age 23.5 years) solved simple arithmetic problems in digit and verbal format, using Siegler's choice, no-choice method. In the choice condition, they produced the answer and gave a self report of how they solved it. In the no-choice condition, they were asked to use only retrieval. Naming latencies of numerals in both formats were assessed. Verbal problems were solved more slowly than digit problems in all conditions but format did not interact with problem size...
Show moreA total of 96 adults (mean age 23.5 years) solved simple arithmetic problems in digit and verbal format, using Siegler's choice, no-choice method. In the choice condition, they produced the answer and gave a self report of how they solved it. In the no-choice condition, they were asked to use only retrieval. Naming latencies of numerals in both formats were assessed. Verbal problems were solved more slowly than digit problems in all conditions but format did not interact with problem size effect for reaction times. This latter result does not support an effect of presentation format on calculation processes. Participants also named faster digits than verbal numerals. Smaller reaction times and three times as many errors were associated with the no-choice compared to the choice condition. Mathematical aptitude also had an effect. High arithmetic skill was related to smaller reaction times, more retrieval use and fewer errors.

Abstract/Description

This was an exploratory study of factors that predict individual differences in chemistry learning. Consistent with cognitive learning theory, working memory was assumed to be an important predictor of chemistry knowledge. Measures of chemistry affect, cognitive ability, demographics and mathematical ability were examined in relation to visual/schematic and algebra-like stoichiometry chemistry word problem solving ability and strategy use. 139 undergraduate students (91 females, 48 males) at...

Consistent with cognitive learning theory, working memory was assumed to be an important predictor of chemistry knowledge. Measures of chemistry affect, cognitive ability, demographics and mathematical ability were examined in relation to visual/schematic and algebra-like stoichiometry chemistry word problem solving ability and strategy use. 139 undergraduate students (91 females, 48 males) at a major Southeastern university participated in this study (Age ranged from 18 to 39 years (M = 20.70 years of age)). Perceived usefulness of the chemistry material, mathematical ability, GPA, and SGPA uniquely predicted conceptual stoichiometry problem solving ability.
