eric.ed.gov har udgivet: Introduction: Many students with adventitious vision loss or progressive vision loss need to transition from print to braille as a primary literacy medium. It is important that this transition is handled efficiently so that the student can have continued access to a literacy medium and make progress in the core curriculum. For this study, we used constant time delay to teach literary braille contractions and Nemeth Code for Mathematics and Science Notation (hereafter, Nemeth Code) braille symbols to learners with visual impairments who were making the transition from print to braille. Methods: A single-subject, multiple-probe research design was used to test the effectiveness and efficiency of constant time delay to teach literary braille or Nemeth Code. Three female students, aged 13 to 15 years, participated at a… Continue Reading →

eric.ed.gov har udgivet: The Partnership for Assessment of Readiness for College and Careers (PARCC) commissioned a multi-part study to determine the viability of using the drawing response interaction on the PARCC Mathematics Assessment. This study in particular focused on students with disabilities. PARCC has over 40 interaction types on the summative assessments. Why introduce a drawing response interaction? There are several drivers to the addition of this functionality. The first is comparability. While scores across modes are comparable overall, they could be stronger at the lower grades. Students who respond to constructed response on paper can provide drawings. Feedback from students in lower grades from the mode comparability study indicated the desire for a drawing tool. Data from the scoring of paper responses indicates up to 10% of the responses… Continue Reading →

That study focused on the use of certain prosodic and lexical elements in the ClearSpeak speech style and served as a basis for further refinements in that style’s definition and implementation in the MathPlayer software. The primary parameters evaluated are students’ success in drawing conclusions about the content and structure of certain math expressions and their perceptions regarding the helpfulness of the pace and wording of different text-to-speech renditions of… Continue Reading →

eric.ed.gov har udgivet: Introduction: This study analyzed survey responses from 141 teachers of students with visual impairments who shared their experiences about the implementation of Unified English Braille (UEB). Methods: Teachers of students with visual impairments in the United States completed an online survey during spring 2016. Results: Although most respondents knew if their state had a UEB transition plan, few participated in its development. Half attended workshops to learn about word-based UEB, but few attended workshops about math-based UEB. They believed their students would be successful in transitioning to word-based UEB but were less sure about their transition to math-based UEB. Discussion: The teachers believed they were more confident in their own skills and their students’ future success with word-based UEB compared to math-based UEB. Additional clarification on the… Continue Reading →

eric.ed.gov har udgivet: The project was conducted to make an online tutoring program for math word problem solving accessible to students with visual impairments (VI). An online survey of teachers of students with VI (TVIs) guided the decision to provide the math content in the form of an iPad app, accompanied by print and braille materials. The app includes audio descriptions of images that illustrate the math problems, an integrated Scratch Pad, options to adjust color and contrast, hints, and videos showing how to solve sample problems. In order to provide access to those needing screen reading technology or screen enlargement, the app utilizes the Apple built-in accessibility features of VoiceOver and Zoom. A study with 19 TVIs and 29 students with VI was conducted to obtain feedback about the… Continue Reading →
