Automated text scoring and real‐time adjustable feedback: Supporting revision of scientific arguments involving uncertainty

This paper describes HASbot, an automated text scoring and real‐time feedback system designed to support student revision of scientific arguments. Students submit open‐ended text responses to explain how their data support claims and how the limitations of their data affect the uncertainty of their explanations. HASbot automatically scores these text responses and returns the scores with feedback to students. Data were collected from 343 middle‐ and high‐school students taught by nine teachers across seven states in the United States.

Principles for Designing Large-Format Refreshable Haptic Graphics Using Touchscreen Devices: An Evaluation of Nonvisual Panning Methods

Touchscreen devices, such as smartphones and tablets, represent a modern solution for providing graphical access to people with blindness and visual impairment (BVI). However, a significant problem with these solutions is their limited screen real estate, which necessitates panning or zooming operations for accessing large-format graphical materials such as maps.

Touchscreen-Based Haptic Information Access for Assisting Blind and Visually-Impaired Users: Perceptual Parameters and Design Guidelines

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.

Comparing Haptic Pattern Matching on Tablets and Phones: Large Screens Are Not Necessarily Better

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.

The current study investigates two questions: (1) Do screen size and grid density impact a user's accuracy on pattern-matching tasks? (2) Do screen size and grid density impact a user's time on task?

Advancing Online and Blended Professional Development Through NSF's DRK-12 Program

The STEM education landscape continuously shifts in response to factors such as changing workforce demands; new knowledge about how children and adults learn; better strategies for broadening participation in under-served and underrepresented populations; and changes in local, state, and national policy. Empowering teachers with new knowledge and approaches to navigate this changing landscape requires ongoing, high-quality opportunities for professional growth.

Classroom Learning Partner Tools Documentation

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.
