Despite the importance of spelling for both writing and reading, there is considerable disagreement regarding how spelling skills are best acquired. During this and virtually all of the last century, some scholars have argued that spelling should not be directly or formally taught as such instruction is not effective or efficient. We conducted a…

The present study tested the "interference hypothesis"-that learning and using more advanced representations and strategies requires the inhibition of prior, less advanced ones. Specifically, it examined the relation between inhibitory control and number line estimation performance. Experiment 1 compared the accuracy of adults' (N = 53)…

The aim of the "Tools of the Mind" prekindergarten curriculum is to enhance children's executive function skills within an instructional context that promotes the basic academic and social skills that prepare them for kindergarten and beyond. To investigate the effectiveness of "Tools" in achieving this aim, the authors are…

The purpose of this study was to investigate whether physicality (actual and active touch of concrete material), as such, is a necessity for science experimentation learning at the kindergarten level. We compared the effects of student experimentation with Physical Manipulatives (PM) and Virtual Manipulatives (VM) on kindergarten students'…

The Internet is an effective learning tool for gifted children because it allows them to independently select the areas in which they have talent. The Internet also enables children to discover and maximize their potential. However, younger children might not have a large enough vocabulary to surf the Internet, even if they are gifted. For…

We designed two experiments to investigate subsyllabic unit preference in reading Pinyin in Chinese kindergarteners. Pinyin is an alphabetic transcription used in Mainland China to assist children in learning to read Chinese characters. In Pinyin instruction, teachers rely heavily on onset-rime division. Spoken Chinese, however, encourages…

Novel word learning is reported to be problematic for children with severe language impairments (SLI). In this study, we tested electronic storybooks as a tool to support vocabulary acquisition in SLI children. In Experiment 1, 29 kindergarten SLI children heard four e-books each four times: (a) two stories were presented as video books with…

We investigate short and long-term effects of early childhood education using variation created by a unique policy experiment in British Columbia, Canada. Our findings imply starting Kindergarten one year late substantially reduces the probability of repeating the third grade, and meaningfully increases in tenth grade math and reading scores.…

We evaluated the effects of presession satiation on challenging behavior and academic engagement during subsequent classroom activities for three 5-6 year-old children with autism. The percentage of 10-s intervals with challenging behavior and academic engagement during 20-min classroom activity sessions was observed under two conditions. One…

The purpose of the study was to update previous meta-analytic findings on the effectiveness of using similarities and differences as an instructional strategy. The strategy includes facilitating student comparison, classification, use of analogies, and use of metaphors. Previously, Marzano, Pickering, and Pollock reported a mean effect size of…

Computer-based instruction in kindergarten classrooms can be controversial, but one Los Angeles charter school is showing promising results and plans to expand the hybrid approach. The school conducted an experiment with a teaching method called blended learning, in which students learn from computers as well as teachers. The kindergarten…

This paper analyzes 12 recent within-study comparisons contrasting causal estimates from a randomized experiment with those from an observational study sharing the same treatment group. The aim is to test whether different causal estimates result when a counterfactual group is formed, either with or without random assignment, and when statistical…

This research examines the development of children's understanding that people's judgments may be skewed by relationships, and that situational factors may make it difficult to be impartial. One hundred and seventy-one adults and children between kindergarten and eighth grade heard stories about judges in contests with objective or subjective…

Our purpose is to offer children tasks so they can make drawings as diverse and different from each other whilst trying to avoid imitation. Achieving this goal involves the increase of children's creativity. The paper is theoretically based on the consideration of creativity as the ability to create "something new, original, and in accordance…

This booklet provides parents of children ages 3 through 10 with information, tools, and activities they can use in the home and community to help their child develop an interest in the sciences and learn about the world around them. This brochure was drawn from the larger booklet in the "Helping Your Child" series, "Helping Your Child Learn…
