The hypothesis was tested that students with a field-independent cognitive style would learn most about numeration systems if they had minimum guidance and maximum opportunity for discovery through the use of manipulative materials. Data were gathered on 46 prospective elementary school teachers. The hypothesis was supported. (Author/MH)

The relationship between locus of control and three dimensions of discovery learning was investigated. Mathematics students were assigned to treatments differing in level of guidance, inductive or deductive sequencing, or use of small groups. Aptitude-treatment interaction occurred between locus of control and small-group instruction. (Author/GK)

This study examined the interaction between field independence and two treatments: small group and individual mathematics instruction. There was significant interaction when achievement was the dependent variable, but not when student ratings of the course were used. The interaction was due more to general ability than cognitive style. (Author/GSK)
