The current study examined how parental cognitive stimulation, emotional support, and intrusiveness measured during children's prekindergarten year were related to children's verbal and nonverbal abilities 1 year later. Participants were 110 Head Start children and their caregivers from primarily rural and low-income backgrounds. Analysis of children's scores on the McCarthy Scales of Children's Abilities confirmed the predictive utility of cognitive stimulation, emotional support, and intrusive behavior for perceptual scores (20% of the unique variance) as well as the predictive utility of emotional support and intrusive behavior for verbal scores (15% of the unique variance). Parental emotional support during guidance of problem solving (positive feedback) explained statistically significant unique variance in children's perceptual scores beyond other measures of emotional support. Cognitive stimulation moderated the relation between positive feedback and perceptual scores. Although other syntactic forms of maternal utterances such as commands did not explain statistically significant unique variance in children's scores beyond emotional support and intrusive behavior, mothers' questions did. Specific policy implications of the effects are discussed.

Seventy-four preschool-age maltreated children's receptive and expressive language, speech skills, general language and cognitive abilities were assessed to investigate the language, speech and cognitive skills of abused, neglected, and abused and neglected children. While all three groups were delayed, neglect was the type of maltreatment most strongly associated with both expressive and receptive language delays and overall language delay. The three groups did not differ in general cognitive development. The most important feature of our data, relative to a Vygotskian perpective, is that language development is particularly vulnerable in an environment devoid of parent-child social language exchange.

State and national standards call for teaching evolution concepts as early as kindergarten, which provides motivation to continue developing science instruction and curriculum for young learners. The importance of addressing students' folk theories regarding science justifies teaching evolution early in K-12 education. In this project, we developed, implemented, and researched standards-based lessons to teach elements of evolution (speciation and adaption) to kindergarteners and second graders. Our lessons attended to the students' prior knowledge, and utilized inquiry and modeling to teach and assess their ability to recognize patterns of similarity and differences among organisms. Using their products and comments as evidence, it was apparent the students were able to communicate recognition of patterns and effectively apply their knowledge in near transfer activities, indicating they achieved our learning objectives. This provides support for teaching evolution concepts in the early grades and evidence of the ability for young children to effectively engage in supported inquiry and modeling for learning science. ). Yet, there are mixed perspectives of how and when various aspects of science, e.g. evolution, should be included in the elementary curriculum (NRC 2000). There is a range of pedagogical and philosophical perspectives influencing how to approach teaching evolution to early elementary students (Metz 1995). The range of perspectives of early childhood science education raises the question of how effectively early elementary students can learn from lessons structured to teach evolution. We address this question by assessing kindergarten and second grade students' learning in response to biological similarities and differences, concepts that are fundamental to the evolutionary concepts of adaption and speciation. Teaching Science in Early Elementary GradesRegardless of mandates to improve science education for early elementary students, the efforts may not be widely embraced by educators. Eshach and Fried (2005) report reluctance to include scientific concepts in early elementary courses based on the belief that these concepts are too abstract for younger Evo Edu Outreach (2009) 2:458-473
