Across multiple age groups and academic disciplines, research has shown that incorporating multimodal signs into instruction can enhance student learning. For instance, gesture might be synchronized with speech or written signs. The present study reports on the semiotic resources used by a teacher-researcher to support kindergarten students'…

While traditional anatomy education often emphasizes passive learning and rote memorization, it seldom employs constructivist theories that focus on active, hands-on experiences for effective learning. This study tests the hypothesis that tactile experiences with modeling clay enhance geometric mental representation more effectively than verbal…

Objective: This study reviews the status of materials in curriculum and reform, as reflected in a network case study of curriculum in one kindergarten classroom in the United States. This paper focuses on the events leading up to and building upon one inquiry unit that became a focal point in promoting progressive curriculum reform at the school.…

This study aimed to examine whether withholding answers coupled with physical manipulation of material strengthened by the self-explanation effect (SEE) contribute to the development of a deeper conceptual understanding and retention of learning about motion content in a hands-on (HO) learning environment. The correlation between students'…

This article presents an original puzzle that supports students' development of visual thinking and geometry ideas based on the Van Hiele levels of geometric thought. The "Triangle Puzzle" is one of many tools teachers can use to guide students' learning of geometry. The Van Hiele's theory provides a way to assess and support this…

Magnetic molecular models help students explore molecular structures and interactions. In this study, we investigated how pairs of students used magnetic models to explore hydrogen bonding and the 6-fold symmetry of snowflakes. Fourteen first-year students enrolled in a chemistry unit participated in pairs. Students' interactions with the magnetic…

Many students struggle to understand the sometimes counterintuitive and complicated organization of the retina. As soon as they begin to grasp these complex relationships, we add another confusing concept: the organization of receptive fields of individual ganglion cells. Publishers provide figures in textbooks and videos, but like many topics in…

In 1981 I published a note on "Balancers" as part of a series of illustrations drawn from 19th-century physics texts. Some months later a wonderful present arrived from a physics teacher in Japan, showing the range of our journal. This was the Horse and Rider Balancer in Fig. 1 that was just like the woodcut in my note. The little…

The objective of the current study was to assess how a LEGO intervention, implemented by a grandparent and a parent at home, affected social interactions for four children (two girls, two boys; ages 6-7 years) on the autism spectrum in China. A multiple probe design across four families was used. Grandparents and parents were trained to use…

To understand the ways that manipulatives might support changes in students' reasoning about algebraic generalizations, a constructivist teaching experiment was conducted with two sixth-grade students. The students interpreted numerical situations with units of one and could construct units of units in mental activity. Initially, the students'…

Similarity is a crucial concept introduced in the 8th grade, and it is further developed and reinforced through associations during high school. This research aims to investigate how 8th grade students construct the concept of similarity using concrete manipulative support within the framework of APOS theory. The research was conducted as a…

The authors discuss loose parts -- pipe cleaners, acorns, fabric, stones, and so forth -- as versatile materials not originally intended for children's play that they can manipulate, modify, and use in their play activities. The authors review the historical foundations of loose parts play, focusing on influential individuals and theories, and…

Phylogenetic trees are used throughout biology to represent evolutionary relationships and communicate ideas about evolutionary processes. Dedicated instruction in how to read and interpret phylogenetic trees (i.e., tree thinking) is necessary for students to be able to access this information. There are many cognitive barriers to mastering…

Despite the growing popularity of both flipped classrooms and digital manipulatives, there is a need for empirical research to examine the impact of combining these instructional strategies in the context of an Algebra 1 course (Alsaeed, 2017; Brown et al., 2001). This study is grounded in Kolb's learning cycle, the Technological Pedagogical…

Background: Young people with learning disabilities use many digital technologies to undertake meaningful and social activities in their everyday lives. Understanding these digital activities is essential for supporting their digital participation. Including them in exploring their digital activities can be challenging with conventional…
