We investigated students' understanding of proportional, inverse proportional, and affine functions and the way this understanding is affected by various external representations. In a first study, we focus on students' ability to model textual descriptions of situations with different kinds of representations of proportional, inverse…

Visual juxtaposition is inquiry through contrast, facilitated by side-by-side positioning of two images, or images and text. When combined with a theoretical foundation that explores interactions between the material and discursive elements of visual data, juxtaposition creates opportunities for qualitative analysis that are not as readily…

Purpose: When learning novel word forms, preschoolers with developmental language disorder (DLD; also known as "specific language impairment") produce speech targets inaccurately and with a high degree of intraword variability. The aim of the current study is to specify whether and how layering lexical-semantic information onto novel…

This study investigated the effects of multimedia and modality design principles using a learning intervention about Australia with a sample of college students and employing measures of learning outcomes, visual attention, satisfaction, and mental effort. Seventy-five college students were systematically assigned to one of four conditions: a)…

The purpose of the study was to evaluate the effects of a system of least prompts procedure and use of a graphic organizer to teach the academic literacy standard of comparing characters in text for elementary students with moderate and severe intellectual disability. A multiple probe across participants design was used to evaluate the results.…

The efficacy of a research-based fraction sense intervention for sixth graders with or at risk for mathematics difficulties (N = 52) was examined. The intervention aimed to build understanding of fraction magnitudes on the number line. Key concepts were taught with a narrow range of denominators to develop deep understanding. The intervention was…

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…

In this study, we address the research question: "How might child-created billboards about HIV and AIDS help facilitate more open discussions between parents and children?" The premise of our study is that there may be considerable potential for using multimodal forms of representation in makerspaces with young children to create more…

This paper reports some experiments on probabilistic reasoning designed to investigate the impact of the probabilistic problem presentation format (verbal-numerical and graphical-pictorial) on subjects' confidence in the correctness of their performance, other than the calibration between confidence and accuracy. To understand the potential effect…

As today's classrooms become more and more diverse, there is a growing need to explore the intersection between English Learners (ELs) and students with learning disabilities (LD) in the content-specific instruction of mathematics problem solving. The aim of this study was to determine which types of instructional scaffolds may be used by math…

Field placement allows pre-service teachers (PSTs) to gain experience teaching culturally and linguistically diverse students. However, little is known about how PSTs engage with multilingualism during field placement. This article investigates how PSTs capitalise on their own as well as their students' linguistic repertoires during field…

The purpose of this study was to examine the effects of student-generated drawing and imagination on learning recall, learning transfer, and cognitive load, and also students' attitudes towards the learning strategies when learning a computer-based science text, compared to learning with provided pictures. The study used three groups: drawing…

Tablet devices, as assistive and instructional technologies, can be highly effectual pedagogical tools with multifaceted benefits, such as the ability to integrate multimedia and the ability to track student progress over time. The unique value of particular assistive and instructional technologies explains, in part, why they are more widely used…

Objective: "MyPlate," a tool for communicating the federal nutrition guidelines in the USA, may contribute to healthy diets and behaviours, yet whether and how it is used by teachers and school principals is unknown. The purpose of this study was to examine (1) the prevalence of using nutrition lessons and MyPlate guidelines by K-12…

Reading and technology are believed to have a strong link with learner autonomy. This research aims at investigating how digital reader response tasks in a reading class promote learner autonomy. The students were given reader response tasks which challenged them to respond to texts using digital infographic and presentation tools in…
