Multimodal imaging studies targeting preschoolers and low-functioning autism spectrum disorder (ASD) patients are scarce. We applied machine learning classifiers to parameters from T1-weighted MRI and DTI data of 58 children with ASD (age 3-6 years) and 48 typically developing controls (TDC). Classification performance reached an accuracy,…

Relative adiposity (%Fat) was measured using a smartphone-based application in a convenience sample of adults aged 20-52 years (n = 32, 68.7% female, 84.3% White/Caucasian, 26.7 ± 3.5 kg/m2) across different body positions (Anterior versus Posterior) on consecutive days (Day 1 versus Day 2). A reference photo was obtained from the posterior view…

In a world 'flooded' with data, students in school need adequate tools as Visual Analytics (VA), that easily process mass data, give support in drawing advanced conclusions and help to make informed predictions in relation to societal circumstances. Methods for how the students' insights may be reformulated and presented in 'appropriate' modes are…

Together, this dissertation describes the combined importance of visuality, pedagogy, and forces like power in deaf education. It documents a multimethod qualitative research design with case study and grounded theory methods to examine conflicting issues about "how" and "why" vision is used in deaf pedagogy. Initially,…

Any body of research evolves over time. Previous understandings become more nuanced, ideas are supported or rebuked, and, eventually we arrive at a clearer view of the issue. The research on score comparability across computerized devices is no exception. CCSSO [Council of Chief State School Officers] and the Center for Assessment have published…

Although extensive research has shown the educational value of different types of interactive visualizations on students' science learning in general, how such technologies can contribute to English learners' (ELs) understanding of complex scientific concepts has not been sufficiently explored to date. This mixed-methods study investigated how…

In this paper, I describe preliminary work on a new research project in learning analytics at Arizona State University. In conjunction with an innovative remedial mathematics course using Khan Academy and student coaches, this study seeks to measure the effectiveness of visualized data in assisting student coaches as they help remedial math…

A visual regression analysis using the least absolutes method (LAB) was developed, utilizing an interactive approach of visually minimizing the sum of the absolute deviations (SAB) using a bar graph in Excel; the results agree very well with those obtained from nonvisual LAB using a numerical Solver in Excel. These LAB results were compared with…

Multimodal texts that combine words and images produce meaning in a different way from monomodal texts that rely on words. They differ not only in representing the subject matter, but also constructing relationships between text producers and text receivers. This article uses two multimodal texts and one monomodal written text as samples, which…

This article provides evidence from a 4-year longitudinal study on the comparative use of illustrative video podcasts during Economic Geography lectures vis-à-vis traditional educational methods in order to guide pedagogic practice and future research on the relative merits of technology-enhanced learning in higher education. Key benefits derived…

This paper focuses on corrective feedback and examines how trainee-teachers use different semiotic resources to soften feedback sequences during synchronous online interactions. The ISMAEL corpus of webconferencing-supported L2 interactions in French provided data for this qualitative study. Using multimodal transcriptions, the analysis describes…

Recent decades have witnessed a growing interest in intervention-based assessment to promote and enhance children's learning. In this study, we explored the potential effect of an experimental visual-spatial intervention procedure and possible training benefits of two prompting modalities: one group received training with verbal and visual…

This guide is intended for all teachers who wish to enhance their curriculum by incorporating objects and photographs into their lesson plans. Kindergarten and elementary, middle, and high school classrooms can all benefit from expanded use of these materials. The guide can be used across a range of subject areas including history, community,…

The texts that adolescents encounter today are often multimodal, meaning they incorporate a variety of modes, including visual images, hypertext, and graphic design elements along with written text. Expanding the perspectives readers use to make sense of the multimodal texts is an important aspect of comprehension instruction. Moving beyond the…

This paper explores how students, as multimodal storytellers, can weave powerful narratives blending modes, genres, artefacts and literary conventions to represent the real and imagined in their lives. Part of a larger ethnographic case study of student writing in a middle years class for immigrant students learning English as an additional…
