Young children are able to benefit from early science teaching but many preschool teachers have not had opportunities to deepen their own understanding of science or to develop their pedagogical content knowledge (PCK) in relation to specific science topics and concepts. This study presents the results of efficacy research on Foundations of…

The emergence and establishment of Universal PreKindergarten (UPK) programs in New York school districts have proliferated over the past ten years; nonetheless, limited attention has been paid to the "process quality" dimensions of these programs (Mashburn, Hamre, Downer, Barbarin, Bryant, Burchinal, Early, & Howes, 2008). Existing…

This paper describes findings from a blocked randomized design (BRD) field study conducted to examine the "Next Generation Preschool Math" (NGPM) program's implementation in preschool classrooms and promise in improving young children's mathematic learning. NGPM integrates traditional preschool activities with developmentally appropriate…

Biological kinds undergo a variety of changes during their life span, and these changes vary in degree by organism. Understanding that an organism, such as a caterpillar, maintains category identity over its life span despite dramatic changes is a key concept in biological reasoning. At present, we know little about the developmental trajectory of…

The need for a scientifically-literate American population has gained great prominence on the educational landscape of priorities over the past decade; young children will be increasingly exposed to the STEM fields and encouraged to excel in these areas. Professional development is key to assuring that early childhood teachers provide children…

English-speaking preschoolers who knew letters but were nonreaders (M = 4 years 9 months; n = 60) were taught to segment consonant-vowel (CV), VC, and CVC words into phonemes either with letters and pictures of articulatory gestures (the LPA condition) or with letters only (the LO condition). A control group received no treatment. Both trained…

This study explores pre-service early childhood teachers' efficacy for teaching mathematics. Thirty-eight participants completed the short form of the Teacher Efficacy Scale and the Teacher Beliefs Scale before and after they conducted a clinical interview with a child around a mathematical topic. Results indicated a significant increase in…

Described here is a study on the efficacy of a digital media-rich curriculum based on the idea that children can learn best from "media synergy", that is, when children have opportunities to learn skills by engaging in repeated practice with them in many different formats and media (Neuman, 1995). The study is part of the "Ready to…

"Let's Begin with the Letter People"[R] is an early education curriculum that uses 26 thematic units to develop children's language and early literacy skills. A major focus is phonological awareness, including rhyming, word play, alliteration, and segmentation. Children are encouraged to learn as individuals, in small groups, and in a…

A randomized-trials design was used to evaluate the effectiveness of a preschool mathematics program based on a comprehensive model of research-based curricula development. Thirty-six preschool classrooms were assigned to experimental (Building Blocks), comparison (a different preschool mathematics curriculum), or control conditions. Children were…

"Waterford Early Reading Level One"[TM] is an emergent literacy curriculum that uses computer-based technology to prepare children for reading. It begins with a tutorial to familiarize the child with the computer and mouse and a reading placement evaluation to assess and determine whether a child should work on "Level One"…
