This work addresses visual content accessibility for blind and low vision communities through the lenses of technique development and community engagement with an overarching question of "How can we make tactile pictures more available?" This inquiry takes a participatory, action-based design approach to break this question down based on…

Providing effective mathematics instruction to learners with disabilities is challenging enough in a classroom. Providing the same level of high quality instruction can be more difficult in an online environment. This article describes an effective use of virtual tools for mathematics that can both engage students and provide the supports they…

Online learning has become a daily mode of modern education, and its effect on learning outcomes has also been widely discussed. Engagement, satisfaction and academic performance are often used to measure learning outcomes, while factors such as physical motorization, information presentation and embodied learning experiences are often used to…

Fifty-one 23-to-55-month-old-infants faced two apparatuses that required the use of a rigid (box apparatus) or flexible (hose apparatus) stick-like tool to retrieve a toy stuck inside. Before attempting the extraction, however, they had to pick the only one tool (of three) on display that had the appropriate rigidity/flexibility to be effective.…

Empirical evidence indicates that students are not learning geometry with relational understanding of the concepts. Studies have shown that digital technologies can support students in mathematics. The purpose of this study was to find which technologies and technological affordances are specific to learners of geometry. This paper presents the…

Learning content-specific vocabulary is critical for students especially in content areas such as science. However, direct vocabulary instruction is lacking in many classrooms. This case study examined vocabulary instructional strategies within a 6th grade science classroom. The following questions were addressed: (1) What science vocabulary…

We conducted two experiments to address questions over whether 9-month-old infants believe that objects depicted in realistic photographs can be picked up. In Experiment 1, we presented 9-month-old infants with realistic color photographs of objects, colored outlines of objects, abstract colored "blobs," and blank pages. Infants most commonly…

This study aims to assess whether the handling of concrete ball-and-stick molecular models promotes translation between diagrammatic representations and a concrete model (or vice versa) and the coordination of the different types of structural representations of a given molecular structure. Forty-one Algerian undergraduate students were requested…

We analyze the interaction of 3 students working on mathematics problems over several days in a virtual math team. Our analysis traces out how successful collaboration in a later session is contingent upon the work of prior sessions and shows how the development of representational practices is an important aspect of these participants' problem…

An extensive body of scholarship has documented the way disciplinary texts and activities are produced and mediated through their relationship to a wide array of extradisciplinary discourses. This article seeks to complement and extend that line of work by drawing upon Witte's (1992) notion of intertext to address the way disciplinary activities…

The primary purpose of the present study was to determine whether recent findings documenting the benefits of text-related motor activity on young children's memory for reading passages [Glenberg, A. M., Gutierrez, T., Levin, J. R., Japuntich, S., & Kaschak, M. (2004). Activity and imagined activity can enhance young readers' reading…

Two experiments tested the DeLoache, Pierroutsakos, Uttal, Rosengren, and Gottlieb (1998) claim that 9-month-old infants attempt to grasp objects depicted in photographs. In Experiment 1, 9-month-olds viewed an object, a photograph of the object, and 2 flat, nonpictorial displays. On average, they reached for the photograph and nonpictorial…

The purpose of this study was to examine the effects of an animated agent that provides instructional scaffolding strategies via a story mnemonic or cuing question with feedback versus instructional scaffolding strategies alone on student achievement of different educational objectives in multimedia learning. Specifically, the study investigated…
