Two conflicting hypotheses were investigated in this study. The first is based on an interference theory of forgetting and assumes that forgetting is largely a function of proactive interference, i.e., a result of interference by previously learned material. The second is based on the improvement of memory due to basic mechanisms that may operate…

The two major objectives of this study were: (1) to develop techniques for quantifying and evaluating properties of a "learning context" (i.e., a sequence of observations generated by subjects in solving a problem), and (2) to determine whether or not there is a relationship between properties of observational sequences generated in solving a…

Examination of 48 Black third and fourth grade students revealed that students presented tasks in a varied format perform no better than those presented tasks in an unvaried format. Low achievers may learn better in varied format conditions. High-achieving Black students more easily adapt to the school learning environment than do low-achieving…

To test the hypothesis that pupil achievement is inversely related to class size, a 5-year study (1959-1964) examined the relationship between class size and pupil achievement in reading and arithmetic. Data were taken from records of the Baltimore public school system for all 16,449 grade 3 pupils in the class of 1959, comprised of 6,568 regular…
