In this article, the authors present a new way of teaching the phases of the Moon. Through the introduction of a "self shadow" (an idea of a shadow that is not well-known), they illuminate students' understanding of the phases of the Moon and help them understand the distinction between the shadows that cause eclipses and the shadows that relate…

Children observe, listen, feel, taste, and take apart while exploring everything in their environment. Teachers can cultivate nature investigations with very young children by offering infants natural objects they can explore and investigate. When adults introduce nature in the earliest stages of development, children will be open to new ideas and…

This article analyzes a hybrid after-school learning activity for children called "New School" (NS). NS is an inter-institutional, collaborative project based on a partnership between a university and local elementary schools that also involves other social actors and institutions. Using a framework of third generation activity theory, the article…

Changes in DNA base-repair may serve as an indicator of the time elapsed since divergence from a common ancestor. DNA sequences can now be analyzed. The simulation presented in this article allows students to observe the accumulation of changes in a randomly mutating sequence of playing cards. The cards are analogous to DNA nucleotide or protein…

Given a 5-peg by 5-peg geoboard, how many different lengths can be made by stretching a rubber band to form an oblique segment between any two pegs? This investigation requires students to make connections to the Pythagorean theorem, congruence, and combinations. With its use of visual representation and a range of mathematical ideas that can be…

Just as mathematical ability begins to form in early childhood, so, too, does the knowledge gap separating low-income children from their more affluent peers, who generally enter school with much greater math knowledge. This gap is troubling given that early deficits in mathematical knowledge can have profound implications for future learning. One…

One of the central challenges of ESL teaching is striking the right balance between form and meaning. In pronunciation pedagogy, this challenge is compounded because repetitive practice, which has been shown to enhance phonological acquisition and promote fluency, is widely viewed as being incompatible with communicative principles. This article…

When response activities and comprehension strategies are combined, classroom instruction can enhance student engagement and understanding of a text, enrich student response, and improve students' awareness of their own strategic reading. This article presents some activities, adapted from the new IRA book "Children's Literature in the Reading…

In this lesson, a ready-to-teach cooperative reading activity, students learn about the effects of plastics in our environment, specifically that certain petrochemicals act as artificial estrogens and impact hormonal activities. Much of the content in this lesson was synthesized from recent medical research about the impact of xenoestrogens and…

With the rapid development of wireless communication and sensor technologies, ubiquitous learning has become a promising solution to educational problems. In context-aware ubiquitous learning environments, it is required that learning content is retrieved according to environmental contexts, such as learners' location. Also, a learning content…

This study aims to strategically use computer-mediated communication (CMC) tools to build online communication environments for problem-based learning (PBL). A six-stage process was proposed for online PBL learning in this study: 1) identifying the problem, 2) brainstorming, 3) collecting and analyzing information, 4) synthesizing information, 5)…

A common challenge for choral teachers is teaching students to listen. Too often, students focus on their own singing and do not hear the other parts around them, thus creating a less unified, even disharmonious sound. Robert Russell, director of choral studies at the University of Southern Maine, has observed that confident singers often sing…

Children can have a new favorite animal every week or even every hour. The more familiar the children become with an animal, the more they will be able to understand how its body form and behavior allow it to survive. Learning about the characteristics of organisms and how organisms relate to their environment is part of the National Science…

Papers from the proceedings of the 14th Annual Conference of the Bulgarian Comparative Education Society were submitted in two volumes. Volume 1 contains papers submitted at the conference held in Sofia, Bulgaria, June 14-17, 2016. Volume 2 contains papers submitted at the 4th International Partner Conference of the International Research Centre…

Teams of students in an upper-division undergraduate Usability Engineering course used a collaborative environment to carry out a series of three distributed collaborative homework assignments. Assignments were case-based analyses structured using a jigsaw design; students were provided a collaborative software environment and introduced to a…
