Three classrooms in one school district, each constituting a separate case,…

The formal operations skills and problem solving performance of 60 gifted girls (grades 4 through 6) were investigated. Ss were given Piagetian tasks which involved conservation of mass and weight, use of proportion, oscillation of the pendulum, and projection of shadows. Among findings were the following: (1) no relationship between IQ and either…

The concern of this paper is with techniques for improving the understandability of statistics textbooks for novices. Understandability is measured by tests of the reader's performance on creative transfer problems that require using text material in novel situations. The focus is primarily on the instructional objective of conceptual…

Children three through six years of age were asked to imitate actions depicted in photographs to determine whether they could interpret information of action in photographs. Twenty children at each of four age levels, 3, 4, 5, and 6 years, were asked to imitate two photos, each showing a young child performing a physical action. Following this…
