The effect of sibling relationship on concept learning of young children taught by child-teachers.

CICIRELLI, VICTOR G. The Effect of Sibling Relationship on Concept Learning of Young Children Taught by Child-Teachers. CmLD DEVELOPMENT, 1972, 43, 282-287. The study investigated the effects of sibling relationship on concept learning. 30 sibling pairs were sampled from each subgroup: boys with older sisters, boys with older brothers, girls with older sisters, and girls with older brothers. For 15 pairs, the older children taught his own sib; the remainder were re-paired. The older child learned the trapezoid concept, then taught the younger. Male learners had higher concept attainment scores than female learners; female sibs were more effective teachers than male sibs or female nonsibs. Results are interpreted in terms of role theory and sibling rivalry, and have application for school practice.
