Understanding neurocognitive mechanisms in children with autism spectrum disorder (ASD) is an essential goal of autism research. Studying young children with ASD or other neurodevelopmental conditions in demanding experimental settings, however, can pose many practical and ethical challenges. In this article, we present practical strategies that…

An essential part of understanding number words (e.g., "eight") is understanding that all number words refer to the dimension of experience we call numerosity. Knowledge of this general principle may be separable from knowledge of individual number word meanings. That is, children may learn the meanings of at least a few individual number words…

In this article, which includes three video clips, the author argues that the small experiments, inventions, strategies, and pauses in young children's play seen in the clips reveal a legitimate form of scientific thinking. He notes that science and play both represent a frame of mind, an attitude toward the events one observes. (Contains 3…

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…

Children learn about properties of materials as they walk through a fabric store, help in the kitchen, or dig in the garden. Directed explorations in the classroom build on these early experiences. In the inquiry-based activity described here, students prepare to learn about wet and dry ingredients (liquids and solids) and how they mix together by…

Teachers at the Freeburg Early Childhood Program know that experimentation with physical science is of great interest to young children, and can begin as early as the age of 3. The constructivist teachers at this experimental school at the University of Northern Iowa worked for six years to develop a center-based approach to physical science with…

Young children are fascinated by how things "work." They are at a stage of development where they want to experiment with the many ways to use an object or take things apart and put them back together. In the process of exploring tools and machines, children use the scientific method and problem-solving skills. They observe how things work, wonder…

SEDL is providing analytic and technical support to three large-scale randomized controlled trials assessing the efficacy of promising literacy curriculum in afterschool settings on student academic achievement. In the field of educational research, competition among research organizations and researchers can often impede collaborative efforts in…

The body is probably one of a child's first science experiments. Young children are curious about their own bodies and how they work. They love to explore how they move (and do not move), the sounds they makes, how they look, how different textures feel on their skin, even how it tastes when they suck their thumb. Activities suggested in this…

Children are fascinated with the world of nature. From the tiniest of seeds to the highest of birds, they wonder "Why?" "How?" and "What can I do with it?" This paper provides intriguing nature activities that provide a solid starting point for expanding children's thinking and learning. Through these activities, children will be building skills…

Two experiments explored whether children's correct answers to counter factual and future hypothetical questions were based on an understanding of possibilities. Children played a game in which a toy mouse could run down either 1 of 2 slides. Children found it difficult to mark physically both possible outcomes, compared to reporting a single…

The development of conceptual understanding in arithmetic is a gradual process and children may make use of a concept in some situations before others. Previous research has demonstrated that when children are given arithmetic problems with an inverse relationship they can infer that the initial and final quantities are the same. However, we do…

What happens when children pour water through a funnel? They begin to understand science and math concepts such as flow, force, gravity, and volume. What happens when children mold sand to create a tunnel? They develop skills in areas such as problem solving and predicting. They also gain knowledge about absorption and the properties of sand and…

Start at the end; that's the way to improve children's plans for investigations. Strange as it may seem, there are times when beginning at the beginning of an investigation is not the best way to start things off. To give children the opportunity to ask questions and plan what to do, sometimes it is best to get them first to consider others' data…

The present paper focuses on the application of a structured template, maximum impact flow (MIF), in order to encourage young students in the area of optics and optical engineering. MIF introduces a template in terms of individual steps and linked functionality and is shown to fuse separate learning tools together into a cohesive unit.…
