Most children, when presented with the option between two drink items, will choose the one with "more." But what exactly do children consider when they recognize one object as having more than another? Is it the perceived surface area or volume of an object? Depending on children's cognitive development, the aspect of measurement on…

In this paper, we explore the challenges experienced by a group of Primary 5 to 6 (age 12-14) students as they engaged in a series of problem-solving tasks through block-based programming. The challenges were analysed according to a taxonomy focusing on the presence of computational thinking (CT) elements in mathematics contexts: preparing…

In recent years, mathematics classrooms in the U.S. and around the world have seen an increasing integration of educational robotics with interest from both students and teachers. Through their robotics coding activities, students in the present study discovered the concepts of special angle pairs in geometry--namely, complementary and…

How might teachers of elementary mathematics pursue antiracism through everyday practices such as leading whole-class discussions? This paper reports on an exploratory study of one White woman teacher's efforts to challenge manifestations of structural racism in classroom interactions with students who are predominantly Black. The results include…

Elevate [Math] is a 19-day (76-hour) in-person summer math program created by the Silicon Valley Education Foundation to help middle school students who are struggling in math to achieve math proficiency, increase their interest in math, and develop a growth mindset. Due to the COVID-19 pandemic, the in-person summer program was adapted to a…

National standards and frameworks for mathematics, computer science, and technology emphasize the importance of teaching all children computational thinking (CT) skills. These skills are important for preparing citizens that are literate in science, technology, engineering, and mathematics and for participation in a society that is rapidly…

This study aims to explore an educational learning environment that supports students to learn conceptual modelling with the unified modelling language (UML). In this study, we call the describing models "UML programming." In this paper, we show an educational UML programming environment for science, technology, engineering, art, and…

This study reports on the instruction provided in district-designed intensive summer reading programs. The Tier 3 intervention was provided to 374 students from 24 school districts who were not meeting the end of third-grade reading benchmarks; students were exiting third grade and entering fourth grade. Observations of the 40 classes were…

Students of today are digital natives who for the most part come to school with experiences that may surpass those of their teachers. They use tablet computers and other devices in their personal lives and are eager to use them in the classroom. For teachers, this means they must integrate technology in ways that allow their students to learn with…

An understanding of unit fractions, and especially of one-half, one-third, and one-fourth, is crucially important for elementary school children's development of number sense (CCSSI 2010). We describe multimodal activities designed to assist elementary school students in gaining a rich understanding of unit fractions. Research has shown (Zhang,…

The authors present the experiences of Wyatt, a nine-year-old whose mother described him as a struggling writer, in a summer digital writing camp. The authors consider how Wyatt was positioned as a writer at camp and how this may have differed from his experiences at school. They found that for Wyatt, being able to compose with digital tools along…

The Read to be Ready campaign emerged from the startling reality of Tennessee's reading achievement data. Only one-third of Tennessee fourth graders scored proficient in the last administration of National Assessment of Education Progress (NAEP) in 2015. Equally concerning, students who fell behind in the early years almost never caught up in…

Teachers who participated in a recent summer institute focused on implementing the Common Core State Standards for Mathematics (CCSSM). Throughout the summer institute, teachers had many in-depth discussions about the meanings they attributed to the Standards for Mathematical Practice (SMPs). In this article, the authors share some of the…

Over a decade ago, Borko (2004) raised the awareness of the education research community to the critical need for studies of teacher professional development (PD) programs. She states on page 13: "My challenge to the educational research community is this: We have much work to do and many questions to answer in order to provide high-quality…

When studying informal science programs, researchers often overlook the opportunities enabled and constrained in each program and the practices reinforced for participants. In this case study, I examined the normative scientific practices reinforced in one-week-long "Herpetology" (the study of reptiles and amphibians) program for…
