NOTE ON THE DOUBLE CENTERING OF DICHOTOMIZED MATRICES

A method is described for the double centering of dichotomized score matrices. It is based on a modification of the r _s coefficient of Guilford in which a second set of values, based on the reversed scoring of the original set, is used. A comparison of indices from matrices centered in such a manner, with some coefficients customarily obtained from score matrices, is presented.

Cooperative Guidance and Instructional Programs for Leadership Preparation

This article outlines a sequential series of leadership programs, from elementary school to college level, that will serve to integrate the guidance and instructional processes. Leadership is viewed as one of the four main categories of talent: “academic, creative, kinesthetic (e.g., crafts, athletics), and psychosocial (e.g., leadership).” It is suggested that potential participants for leadership training might be identified by screening and nomination, case study, program planning and placement, and follow-up and evaluation. A four-front program of counseling-instructional activities including individual counseling, group counseling, seminars, and advanced classes is described. It is hypothesized that the interaction of teachers and counselors in actual curriculum building will lead to genuinely individualized educational programming.
