In this paper we compare pre-COVID-19 and post-2021 Tactile Mental Cutting Test assessment data from blind or low-vision participants including scores and test duration between 2019 and 2022. Results show a statistically significant difference in how long it took participants to complete the TMCT between the two timeframes.

Spatial ability is a well-known predictor of success in science, technology, engineering, and mathematics (STEM) fields. The purpose of this study was to investigate and understand the spatial strategies that were used by blind and low-vision (BLV) individuals as they solved problems on the tactile mental cutting test (TMCT), an instrument that was designed to measure the spatial ability of BLV audiences.

This paper presents a continued reliability analysis of the parallel TMCT subtests A & B with the BLV population. Data was collected from BLV participants attending National Federation of the Blind (NFB) conventions, learning centers for the blind, and STEM-oriented NFB summer camps for high school students.

The purpose of this paper is to explore results from a qualitative study of how high school aged BLV youth used spatial language during a virtual engineering experience administered by the National Federation of the Blind (NFB). Findings from this study can provide recommendations to enhance language in curricula that better reflects BLV students' content and may ultimately encourage more BLV students to pursue careers in STEM fields.

The impetus behind this effort was to create a platform for initial support to TEE professionals who may have a blind and low-vision (BLV) student in their courses. Specific examples, instructions, and applications for many of the commonly-used tools and techniques are included here as part of this overall effort to teach TEE concepts through socially relevant contexts by adapting older methods to facilitate new opportunities in our school systems for BLV youth.

This paper describes the development and preliminary validation of a new spatial ability instrument that is designed to be accessible non-visually. Although additional work is needed to finalize the test, preliminary analysis indicates that the test has high reliability and validity.

This paper seeks to illustrate the first steps in a process of adapting an existing, valid, and reliable spatial ability instrument – the Mental Cutting Test (MCT) – to assess spatial ability among blind and low vision (BLV) populations. To adapt the instrument, the team is developing three-dimensional (3-D) models of existing MCT questions such that a BLV population may perceive the test tactilely with their hands.

This paper discusses the development of the Tactile Mental Cutting Test (TMCT), a non-visually accessible spatial ability instrument, developed and used with a blind and low vision (BLV) population. Data was acquired from individuals participating in National Federation of the Blind (NFB) Conventions across the United States as well as NFB sponsored summer engineering programs. The paper reports on a National Science Foundation funded effort to garner initial research findings on the application of the TMCT. It reports on initial findings of the instrument’s validity and reliability, as well

The Accessible Oceans study will design auditory displays that support learning and understanding of ocean data in informal learning environments like museums, science centers, and aquariums. Most data presentations in these spaces use visual display techniques such as graphs, charts, and computer-generated visualizations, resulting in inequitable access for learners with vision impairment or other print-related disabilities. While music, sound effects, and environmental sounds are sometimes used, these audio methods are inadequate for conveying quantitative information. The project will use sonification (turning data into sound) to convey meaningful aspects of ocean science data to increase access to ocean data and ocean literacy. The project will advance knowledge on the design of auditory displays for all learners, with and without disabilities, as well as advance the use of technology for STEM formal and informal education. The study will include 425 participants but will reach tens of thousands through the development of education materials, public reporting, and social media. The study will partner with the Smithsonian National Museum of Natural History, Woods Hole Oceanographic Institution Ocean Discovery Center, the Georgia Aquarium, the Eugene Science Center, the Atlanta Center for the Visually Impaired, and Perkins School for the Blind.
The project will leverage existing educational ocean datasets from the NSF-funded Ocean Observatories Initiative to produce and evaluate the feasibility of using integrated auditory displays to communicate tiered learning objectives of oceanographic principles. Integrated auditory displays will each be comprised of a data sonification and a context-setting audio introduction that will help to make sure all users start with the same basic information about the phenomenon. The displays will be developed through a user-centered design process that will engage ocean science experts, visually impaired students and adults (and their teachers), and design-oriented undergraduate and graduate students. The project will support advocacy skills for inclusive design and will provide valuable training opportunities for graduate and undergraduate students in human-centered design and accessibility. The project will have foundational utility in auditory display, STEM education, human-computer interaction, and other disciplines, contributing new strategies for representing quantitative information that can be applied across STEM disciplines that use similar visual data displays. The project will generate publicly accessible resources to advance studies of inclusive approaches on motivating learners with and without disabilities to learn more about and consider careers in STEM.
This Pilots and Feasibility Studies project is supported by the Advancing Informal STEM Learning program, which seeks to advance new approaches to, and evidence-based understanding of, the design and development of STEM learning in informal environments. This includes providing multiple pathways for broadening access to and engagement in STEM learning experiences, advancing innovative research on and assessment of STEM learning in informal environments, and developing understandings of deeper learning by participants.
Astronomy has been an inherently visual area of science for millenia, yet a majority of its significant discoveries take place in wavelengths beyond human vision. There are many people, including those with low or no vision, who cannot participate fully in such discoveries if visual media is the primary communication mechanism. Numerous efforts have worked to address equity of accessibility to such knowledge sharing, such as through the creation of three-dimensional (3D) printed data sets. This paper describes progress made through technological and programmatic developments in tactile 3D
