The joint contribution of early parental warmth, communication and tracking, and early child conduct problems on monitoring in late childhood

The relationship of parental warmth, communication, and tracking (WCT), and child conduct problems in early elementary school (age 5.5 years) to monitoring in late elementary school (age 9.5 years) was longitudinally examined in a sample of 267 boys and girls. WCT in kindergarten was associated with lower kindergarten levels and less growth of conduct problems into the first grade, and was prospectively associated with effective monitoring in the third and fourth grades. Overt and covert conduct problems in kindergarten and growth in covert problems during kindergarten and first grade were associated with less effective later monitoring. Early conduct problems mediated the prospective association of WCT on later monitoring. The results are described in a transactional model of parent-child relationships and child problem behavior.

Best Practice in Middle-School Science

Using socio-ecological theory, this study explores best practice (educational practices correlated with higher student performance) in middle-school science. Seven schools with consistently higher student performance were compared with three demographically similar, average-performing schools. Best practice included instructional approaches (relevance and engagement, inquiry, differentiated instruction, collaborative work, moderate amounts of homework, and integration of language literacy and science) and administrative practices (nurturing a climate of opportunity to succeed in science, offering professional development based on data and dialogue, engaging teachers in standards-based curriculum revision and alignment, and recruiting the right fit of teacher). It is argued that best practice entails multiple levels of teaching and administrative praxis that together form a school-wide socio-ecological system conducive to higher performance.
