Early Child Language Mediates the Relation Between Home Environment and School Readiness

Home environment quality is a well-known predictor of school readiness (SR), although the underlying processes are little known. This study tested two hypotheses: (a) child language mediates the association between home characteristics (socioeconomic status and exposure to reading) and SR, and (b) genetic factors partly explain the association between language and SR. Data were collected between 6 and 63 months in a large sample of twins. Results showed that home characteristics had direct effects on SR and indirect effects through child language. No genetic correlation was found between language and SR. These results suggest that home characteristics affect SR in part through their effect on early language skills, and show that this process is mainly environmental rather than genetic in nature.     

Wirkungen zentraler Abschlussprüfungen im Mehrebenensystem Schule. Eine Zwischenbilanz internationaler und nationaler Befunde und Forschungsdesiderata

Statewide exit exams have become a central governance instrument at the end of secondary schooling in Germany. In the article, the current state of research in Germany is systematized from an international comparative perspective in relation to intended and unintended effects. Findings regarding state exam policies and effects at the school and instructional level are presented as an interim report on a comparably young field of research. The findings show differences by states, subjects and courses which suggest that there is no general effect of statewide exams. In this context, future research should account for the heterogeneity of exam procedures to a greater degree.     

Effects of Multimedia versus Live Professional Development on Teachers’ and Students’ Performance Related to the Question Exploration Routine

In each of two studies, teachers were randomly assigned to either a Virtual Workshop (VW) group that used a computerized professional development program or an Actual Workshop (AW) group that participated in face-to-face professional development, including discussion, feedback, and collaboration. In both studies, teachers’ posttest scores related to their knowledge of the Question Exploration Routine and their plans for using it were significantly higher than their pretest scores. In Study 2, both groups’ posttest scores with regard to implementation and planning of the routine were significantly greater than their pretest scores. There were no significant differences between the groups at posttesting on any measure. The posttest knowledge scores of the whole groups of students and the subgroups of students with LD being taught by both groups of teachers were significantly higher than their pretest scores. All teachers indicated that they were satisfied with the training and the routine. VW teachers in both studies indicated that they were satisfied with the software program.
