This study sought to clarify the relationships between modes of presentation (verbal vs spatial), explicitness of presentation (little or much), and student aptitudes (verbal vs spatial). Findings are discussed and several areas for future aptitude-treatment-interaction research are suggested. (Author/JEG)

Ninth-grade students were given a battery of cognitive aptitude tests and randomly assigned to verbal or figural mathematics instruction. Learning and retention were correlated with the aptitude measures and other fixed variables; regression analysis indicated the importance of memory, semantic factors, and sex difference. (SD)

The impact of aptitude differences on learning performance is assessed. As a result of the assessment, instructional strategies are being developed to make efficient training programs for men of differing aptitude levels. Observations were that the high level group did better when left without a structured training program. The middle range was…

Describes an aptitude treatment interaction (ATI) hypothesis used to investigate relationships among aptitudes and science instructional treatments in terms of student performance. It is proposed that ATI research work in science education will systematically yield reliable generalizations about how to adapt instruction to individuals with…

The study concerned (1) identifying component processes of discovery and rule learning; (2) describing differences in learning outcomes produced by the two instructional methods, and; (3) optimizing learning. It was believed that understanding the effects of aptitude, instructional methods, and their interaction is important in the study of…

Discusses the individualization of instruction as it relates to learner characteristics, instructional environment, instructional treatment, and their interaction. Practical considerations for learners, instructional treatments, and learning outcomes emanating from the literature on aptitude-treatment interaction are suggested. (RAO)

Describes a heuristic model that facilitates the conceptualization of linguistic-imaginal processes and forms the basis for a method of relating learner aptitudes to specific instructional stimuli in science education. (MLH)

Investigates a method to predict best and least suited students for the ISCS instructional approach. Aptitude-treatment interactions associated with ISCS instruction and a set of aptitude, attitude, and skill factors were utilized to make and verify predictions on two dependent variables--achievement and success. (Author/GA)

This report is a review of current literature on the relation of aptitudes to learning outcomes under different instructional methods or conditions. Included are: (1) aptitude-instructional treatment interaction studies; (2) notes on new methodological problems; (3) and studies of individual differences in laboratory learning arrangements.…

Twelve research reports related to mathematics education are abstracted and analyzed. Four of the reports deal with various teaching methods, four with student aptitudes, four with student learning and understanding, and one with classroom practices. Research related to mathematics education which was reported in RIE and CIJE between October and…

Arguing that a thorough understanding of time and its use in school learning may help improve the schools the author reviews the research pertaining to models of school learning, mastery learning, and the parameter of time in the learning process. (JM)

This study of sixth graders showed that deductive teaching was significantly more effective than inductive instruction for some pupils. (MM)
