Touchscreen-based smart devices, such as smartphones and tablets, offer great promise for providing blind and visually-impaired (BVI) users with a means for accessing graphics non-visually. However, they also offer novel challenges as they were primarily developed for use as a visual interface. This paper studies key usability parameters governing accurate rendering of haptically-perceivable graphical materials.
Significance: Touchscreen-based, multimodal graphics represent an area of increasing research in digital access for individuals with blindness or visual impairments; yet, little empirical research on the effects of screen size on graphical exploration exists. This work probes if and whenmore screen area is necessary in supporting a patternmatching task.
Classroom Learning Partner (CLP) tools allow students and teachers to create, annotate, and manipulate visual representations to solve math problems. The tools may be used for a number of mathematical purposes, but were mainly conceived to assist in creating visual representations for multiplication and division. The underlying model of multiplication and division assumed by the current set of tools involves a repetition of groups of the same size.
Many teachers use online professional development websites, but little is known about what teachers actually learn from them. This study explored teacher use of an online video-based learning website with over 37,000 members. It used web analytics to study user selection of video resources and coding of website commentary to analyze teacher responses to videos. The results indicated that teachers commonly view video clips designed for immediate use rather than reflection and respond to videos by evaluating the pedagogy positively.
Many teachers are turning to online professional development to meet their learning needs, but the vast array of available opportunities may be overwhelming. This article provides a framework for making sense of common online teacher learning opportunities. It also suggests situations where online professional development may be most useful and presents a challenge for educators to consider when engaging in online learning.
Does the promise of competency-based PD outweigh the challenges to implementing it? Do we really want competency-based PD or just more effective, sustained, job-embedded PD like instructional coaching, lesson study, and the like. Read this blog by Meg S. Bates as she ponders these questions and more.
