Extends earlier studies investigating possible relationships between student aptitudes and different modes of mathematical instruction. In the study, college students were exposed to either a verbal-pictorial-numeric treatment or a verbal-symbolic-numeric treatment in quadratic inequalities. Interactions between instructional treatment and…

Fifty-nine undergraduate students, divided into two groups to compare the instructional motivational effects of auto-tutorial and conventional instruction, were tested for achievement via performance (Ac), achievement via independence (Ai), and internal-external locus of control. Significant interaction was found between Ac and the two methods of…

Examines differences in course performance and attitude of college students identified by the Rotter Internal-External Locus of Control Scale as external and those identified as internal. An interaction was found between the type of reinforcement expected, type of pacing treatment, and course performance. References are included. (Author/BK)

Effects of alternative modules designed to compensate for precourse memory and motivation differences were investigated for differences in content and task requirement. Interaction analyses on lesson times-to-criterion and criterion test scores indicated compensating treatments were partially effective in improving performance of low-memory,…

Describes research on an adaptation approach designed to extend the aptitude treatment interaction (ATI) concept by applying instructional variations to individuals as opposed to groups within the context of an introductory mathematics lesson adapted from the beginning module in an undergraduate statistics course. A 17-item reference list is…

This study compared the instructional effectiveness of both cued and noncued pictures and cued and noncued text; investigated whether a combination of pictorial and textual cues is the most effective strategy for low and average reading ability students; and compared average and low reading subjects using noncueing and cueing methods.

Describes a statistical integration of findings from 74 studies of visual-based college teaching. Results indicating that students in such instruction generally learned slightly more but that there was no effect on course completion rates or student attitudes are discussed, and 19 references are provided.
