Communicating Prevention: The Effects of the keepin' it REAL Classroom Videotapes and Televised PSAs on Middle-School Students' Substance Use

This study sought to determine if exposure to two communication-oriented activities, videotapes and public service announcements, accounts for changes in substance use among adolescents participating in the Drug Resistance Strategies Project's keepin' it REAL adolescent substance use prevention curriculum. Middle-school students (4,734, 72% Latino) responded to questionnaires related to these analyses. An analysis of covariance (ANCOVA) model was fit separately to six substance use outcomes. The results suggested that intervention students who saw four or five videos engaged in less substance use in the past month than did students who saw fewer videos. Having seen the PSAs one or more times did not predict the reported change in substance use.

Children's Relationships with Peers: Differential Associations with Aspects of the Teacher-Child Relationship

Associations between children's social competence with peers and differential aspects of their teacher-child relationships were examined in a longitudinal sample of 48 4-year-old children enrolled in child care as infants. Toddler security with teacher was negatively associated with hostile aggression and positively with complex peer play and gregarious behaviors. Prosocial behaviors and withdrawing behaviors were associated with preschool security with teacher. Dependence on teachers as a preschooler was associated with social withdrawal and hostile aggression. Positive toddler teacher socialization was associated with higher perceived peer acceptance. Preschool teacher negative socialization was negatively associated with complex peer play, teacher ratings of hesitancy, friendly enactment, and accidental attribution and positively related to teacher ratings of difficulty.     

Doing time—Killing time at school: An examination of the perceptions and allocations of time among teacher-defined at-risk students

“Doing time” is an expression that is generally associated with prisoners who are disconnected from society and find themselves counting the days and minutes until their release from prison. In many respects, at-risk students attending our nation's large, urban, inner-city middle and high schools also consider themselves as not being connected to school or society and to be “doing time” in the classroom. Qualitative and subjective impressions of doing time at school have become the theme of many movies, books, and research articles. This study extends this qualitative type of research by quantitatively framing time allocation preferences and temporal dominance characteristics for a large sample of teacher-perceived “at-risk” students at several large urban high school sites. A sample of normal attaining students at the same school site served as a comparison group. The findings of this research effort generally support other more qualitative studies and indicate that there are strong preferences in at-risk students toward nondirected time-consuming activities (i.e., hanging out, video games, watching TV, etc.) with low-directed to nondirected time preference ratios. Normal attaining students had the reverse pattern, i.e., higher-directed to nondirected time preference ratios and higher preferences toward directed time-consuming activities that might be associated with investments in the schooling process (homework, studying, personal development, etc.). Interpretation of the circles test, a projective psychological procedure for establishing temporal dominance for at-risk students, revealed a general lack of recognition and connectiveness between past, present, and future events in their life and weak temporal dominance or orientation toward the future.     

The Practicum in Study of Student Development: Its Relation to Counselor Preparation

This paper identifies several kinds of counselor activity for which practicum experiences have been or are being designed. These include individual and group counseling, outreach consultation, supervision of practicum students, and the study of student development. The SSD practicum is seen as sensitizing and predisposing the personnel worker to view action research as a relevant and crucial part of counselor education.
