The present study had two primary objectives:(1) to evaluate the relatively long-term (4-6 months) effects of dextroamphetamine on the behavior, achievement, and perceptual

Mental health consultation with individual teachers (IC) or with groups of teachers (GC) was provided in eight elementary schools. On a follow-up questionnaire, GC teachers rated the consultation program more favorably than did IC teachers with regard to "'general usefulness," amount of communication generated between teachers, and amount of knowledge of child development acquired. Ratings of improvement in child behavior and parentschool relations were not significantly different for GC and IC. Apparent effects on ratings of such variables as amount of contact with consultant, diagnosis of children referred, group composition, and administrative commitment are discussed. Results suggest that GC is not only more economical than IC but also is a more effective means of educating and supporting teachers.

Strategy selection and negative instances in concept learning.The Schenectady Kindergarten Rating Scales (SKRS) are a battery of teacheradministered behavior rating scales that have been developed as an economical means of screening large numbers of children in kindergarten so that preventive or remedial programs can be provided for those who are deficient in language, motor, cognitive, or social development (Conrad & Tobiessen, 1967). The present report is a summary of an evaluation of the predictive efficacy of empiricallyderived SKRS profiles. Two general questions were considered: Do children with different diagnoses in first grade have SKRS profiles corresponding to their firstgrade problems; if so, can first-grade diagnoses be predicted on the basis of SKRS profiles? For convenience, the scales are listed and briefly described below in the order in which they appear in the rater's booklet.2 1. Waiting and Sharing (WS), a 7-point scale measuring the child's ability to wait for things, to share possessions, and to take turns. Level ofOrganization of Play (LOP), a 5-point scale concerning the degree to which a child organizes the play material a t hid disposal. 3. CZarity of Speech (CS), a &point scale involving the clarity of a child's apeech and how easily it can be understood. 4. Use of Materials (UM), a 5-point scale concerning the child's ability to represent reality using art materials, 1This invwtigation was supported by P. H. S.
