Ready to learn? Children's pre-academic achievement in pre-Kindergarten programs

We examined children's growth in school-related learning and social skills over the pre-Kindergarten (pre-K) year in state-funded programs designed to prepare children for kindergarten. We expected that children's gains in academic and social skills could be attributed to variations in the structural and classroom process dimensions of program quality. Nearly 3000 (n = 2800) children were randomly selected, four per classroom, from approximately 700 randomly selected, state-funded pre-Kindergarten classrooms in eleven states. Enrollment in pre-K appeared related to gains in academic skills. Children showed larger gains in academic outcomes when they experienced higher-quality instruction or closer teacher–child relationships. Gains were not related to characteristics of the child or program (i.e., ratio, teacher qualifications and program location and length). These findings have implications for a range of state and local policy and program development efforts as well as for theories of contextual influences on development.     

Identifying High-Quality Preschool Programs: New Evidence on the Validity of the Early Childhood Environment Rating Scale–Revised (ECERS-R) in Relation to School Readiness Goals

Research Findings: The Early Childhood Environment Rating Scale–Revised (ECERS-R) is widely used, often to evaluate whether preschool programs are of sufficient quality to improve children’s school readiness. We examined the validity of the measure for this purpose. Item response theory (IRT) analyses revealed that many items did not fit together to measure single dimensions, particularly when rated by consultants as indicating aspects of quality relevant for multiple domains of child development. IRT results also conflicted with the scale developers’ expectations in terms of whether markers that they attached to higher response categories represented higher quality empirically. When reanalyzed based on experts’ ratings, IRT results also showed that relatively few indicators captured the moderate to high range of quality. Practice or Policy: Our results suggest that policymakers should carefully consider whether measures designed for specific purposes are appropriate for other high-stakes uses. We encourage continued refinement of existing quality measures, development of new measures, and the accumulation of evidence for their various uses.     

The Intellectual Structure of Research on Educational Technology in Science Education (ETiSE): A Co-citation Network Analysis of Publications in Selected Journals (2008–2013)

The main purpose of this paper is to investigate the intellectual structure of the research on educational technology in science education (ETiSE) within the most recent years (2008–2013). Based on the criteria for educational technology research and the citation threshold for educational co-citation analysis, a total of 137 relevant ETiSE papers were identified from the International Journal of Science Education, the Journal of Research in Science Teaching, Science Education, and the Journal of Science Education and Technology. Then, a series of methodologies were performed to analyze all 137 source documents, including document co-citation analysis, social network analysis, and exploratory factor analysis. As a result, 454 co-citation ties were obtained and then graphically visualized with an undirected network, presenting a global structure of the current ETiSE research network. In addition, four major underlying intellectual subfields within the main component of the ETiSE network were extracted and named as: (1) technology-enhanced science inquiry, (2) simulation and visualization for understanding, (3) technology-enhanced chemistry learning, and (4) game-based science learning. The most influential co-citation pairs and cross-boundary phenomena were then analyzed and visualized in a co-citation network. This is the very first attempt to illuminate the core ideas underlying ETiSE research by integrating the co-citation method, factor analysis, and the networking visualization technique. The findings of this study provide a platform for scholarly discussion of the dissemination and research trends within the current ETiSE literature.
