The Michelson interferometer is one of the key experiments in modern physics when it comes to the topic of interference (Box 1). Experiments using interferometry have a high historic relevance as well as uses in current areas of research (quantum erasers, gravitational wave detection) and are used in higher education. Because of the high cost of…

Look at your baby or toddler. They are still learning to eat from a spoon, roll over, stack blocks, walk a few steps, or say their first words. It's hard to imagine that even in these early years, young children are being shaped by the biases that surround them in the world. This is why parenting for social justice begins at birth. Get started…

The vast majority of joint attention interventions for children with autism spectrum disorder (ASD) are geared toward toddlers and preschoolers as it is an early developmental skill. However, many of the youngsters do not acquire joint attention despite these early interventions and subsequently do not exhibit joint attention later in life. In the…

Newton's cradle is often discussed in science classrooms as a clear example of the laws of conservation of momentum and energy although it has been shown that this use is somewhat misleading. Approaches to understanding the behaviour of this apparatus are often over-simplified and deficient or over-complex and with little impact among teachers. In…

This article presents the application of the problem-based learning (PBL) methodology for introducing the civil engineering task of bridge design and construction to high school students with a multidisciplinary approach. The materials (toy construction system) and methodology of the workshop are first presented. Then, three examples of arch…

Innovation in the design of curricula is widely discussed. Innovative curricula expose students to a diverse range of learning environments and prompt them to ask questions, stimulating their creativity and allowing them to develop a sense of initiative and to hone their problem-solving skills and ability to apply knowledge to practice. The…

In this essay from a teacher in Argentina, Valeria Vincent describes how she employed Multiple Literacies in Project-based Learning (MLPBL) (Krajcik, Palincsar, and Miller 2015). ML-PBL, an open education free resource, has three design principles that support teacher and student learning and satisfaction. ML-PBL builds on teacher ingenuity and…

The provision of environments that support and afford play is fundamental for young children's experiences, learning and development. Play environments of Early Childhood Education and Care (ECEC) institutions are therefore of great importance for the opportunities provided children to create and engage in a wide range of play. This study examines…

Using participatory observations accompanied by video and audio recordings, this article investigates how negotiations about play scripts evolve during play in two Waldorf kindergartens. In particular, this study aims to examine how child-initiated play can contribute to the development of basic democratic skills in early childhood. The concept of…

Research Findings: There are sparse data on children's use of executive function (EF) and spatial skills in block play. However, there are important implications for studying EF and spatial skills with blocks across cultures, especially regarding best practices for supporting social-cognitive development in under-resourced populations and…

Fidget toys have been marketed as universal educational supports in the absence of a scientific evidence base. This article gives an overview of the existing literature on the effect of fidget toy use on student attention, behavior, and learning, and a review of two competing theoretical approaches to fidget toys: sensory processing theory and…

In this study, we explored whether access to block play is beneficial to mathematical learning for young children in a low-income country. The research, conducted in Papua New Guinea, explored if access to Duplo Lego blocks, across a 7-month period, in early childhood education settings facilitated mathematical learning for children, aged from 5…

Children's block building has long been a focus of psychological research, in part because block building skills are thought to be useful indicators of other abilities such as representational thinking. Block building skills are assumed to progress through developmental stages and a number of measures have been developed to assess these skills. In…

Novice design students struggle to engage with early stage design visualization tools such as sketching and prototyping. Instead students have a preference for designing with digital tools such as CAD modelling, motivated by inhibitions around sketching skill, which in turn leads to fixation and sunk cost effects. These behaviors present a barrier…

Bagless intervention is a term used by professionals to describe early intervention (EI) services in which the provider refrains from bringing a bag of toys into the home for sessions. Instead of using a toy bag to work on child outcomes, the service provider uses materials in the child's home, as well as family routines, to address the…
