Demonstrations that can be used to lead students to wonder and write about basic scientific principles are presented. Each demonstration includes the concept demonstrated, a list of materials, and procedures. Concepts include density and temperature of liquids, contracting matter with heat, atmospheric pressure, dramatic color changes, fireproof…

Four predictive models offering an ecocultural perspective on the educational and personal-social development of children at risk for learning disabilities and other learning problems are proposed: main effect, additive, multiplicative, and compensatory. Preliminary results favor the compensatory and additive models. Both risk and protective…

Fifth grade social behavioral profiles of 75 arrested and nonarrested adolescent boys were assessed to determine their ability to predict the later arrest status of the boys in grades 5-7. Using such measures as teacher ratings of social skills and observations of negative aggressive behavior, 75 percent of subsequently arrested subjects were…

This article reviews major trends in higher education of the twentieth century, noting they have often been beyond the direct control of higher education. He offers seven possible scenarios for the 1990s including restoration of the centrality of liberal education, a racial crisis, student revolts, increasing deficits in numbers of Ph.Ds, and…

Relations between aptitude variables and school achievement were investigated using a model of ability that permits simultaneous identification of general and specific abilities. Subjects were 866 Swedish students who were given aptitude tests in grade 6; results of that test were compared with course grades collected in grade 9. The usefulness of…

Research in the area of grade adjustment methods from the last 27 years is reviewed in the context of admissions selection and of prediction of student performance in college. Contemporary grade adjustment methods can often produce indexes of academic performance with greater reliability than that found with grade point average. (SLD)

This study investigated the predictive relationship between student attitudes and their subsequent achievement in a freshman composition course. Results indicated that academic background and student attitudes were significantly correlated with subsequent grade performance. Attitude variables were more closely related to overall grade performance…

A study in two high school language programs investigated students' oral proficiency (OPI) interview ratings after a typical four-year sequence, degree to which teachers could accurately predict students' ratings, and relationship between classroom achievement and OP ratings. Results provide valuable information for states and school districts as…

Does living in a neighborhood with a high school affect children's decision to continue their schooling? A study of over 300 fifth graders and their parents in three Mexican cities found community residence is a significant predictor of desired schooling, even with comprehensive controls for child and family traits.

Examined institutional advantages of school-age child care (SACC) programming in schools. A study of 63 SACC programs in 2 southeastern states revealed that community support, number of extracurricular activities, and frequency of academic activities significantly contributed to predicting advantages associated with SAC programming. (Contains 23…

Investigated long-term effects of infant temperament on problem behavior and cognitive abilities at age 5 years, taking into account interactions between infant temperament and biological and social risk. Found that when high scores on temperamental factors are combined with social or biological risk, the level of later behavioral problems is…

The use of mathematical models in the experimental analysis of behavior has increased over the years, and they offer several advantages. Mathematical models require theorists to be precise and unambiguous, often allowing comparisons of competing theories that sound similar when stated in words. Sometimes different mathematical models may make…

The current longitudinal study examined the protective effects of parenting processes on measures of adolescent adjustment (health-compromising and violent behaviors) in a sample of high-risk, inner-city, poor African American youth N = 2,867). Parenting processes played an important role in this dangerous developmental milieu. For male…

This study used an established behavioral observation methodology to examine the parenting practices of first-generation Latino parents of children 4 to 9 years of age. The study had three central aims, to examine: (1) the feasibility of using a behavioral observation methodology with Spanish-speaking immigrant families, (2) the utility of the…

The literature on somatic complaints in children without a clear physical medical cause often demonstrates connections with various psychological factors, such as negative emotions and problems handling them, poor self-image, and coping potential. We entered these elements into a structural model to elucidate the relationships among them and…
