This teaching manual is the fourth in a series of seven (accompanied by a manual of self-assessment units) that have been designed for use in bilingual/bicultural programs. The components of the series may be used either individually or together. This manual is intended to familiarize teachers with ways of measuring cognitive styles in children. The teacher's objective is to determine whether a particular child is field sensitive, field independent, or "bicognitive." Two techniques of measuring cognitive style in children, the Portable Rod and Frame Test and the Child Embedded Figures Test, are described, along with their shortcomings. The major part of the manual describes how teachers can determine cognitive styles by observing children in the school setting, with the aid of"Child Rating Forms." These observations are used in assigning children to one of three instructional groups, and a different teaching strategy is used with each group. (Author/AM)
