Eric.ed.gov – Enhancing Basic Academic Skills with Audio-Recordings: A Review of the Literature

eric.ed.gov har udgivet: Because teacher-to-student ratios often make it difficult for teachers to work individually with students on skill-building activities, educators and researchers have developed and evaluated procedures in which audio-recordings are used to improve basic academic skills. In the current paper, we describe and analyze reading, math, and spelling interventions that use audio-recordings to prompt and pace rapid rates of accurate responding. In this review, we provide evidence of internal and external validity of easy-to-use, low-tech, recorded interventions across students (general education students and students with disabilities) and contexts (e.g., individually administered and class-wide). Discussion focuses on future theoretical research related to causal mechanisms and applied research on modifying recorded interventions to enhance learning rates. Link til kilde

Eric.ed.gov – An Evaluation of the Usefulness of Prosodic and Lexical Cues for Understanding Synthesized Speech of Mathematics. Research Report No. RR-16-33

eric.ed.gov har udgivet: The work described in this report is the second phase of a project to provide easy-to-use tools for authoring and rendering secondaryschool algebra-levelmath expressions insynthesized speech that is useful for studentswithblindnessor lowvision.This report describes the development and results of the second feedback study performed for our project, Expanding Audio Access toMathematics Expressions by StudentsWith Visual Impairments viaMathML. 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 – Development of a Math-Learning App for Students with Visual Impairments

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

Eric.ed.gov – Fostering Early Math Comprehension: Experimental Evidence from Paraguay

eric.ed.gov har udgivet: Research indicates that preschool children need to learn pre-math skills to build a foundation for primary- and secondary-level mathematics. This paper presents the results from the early stages of a pilot mathematics program implemented in Cordillera, Paraguay. In a context of significant gaps in teacher preparation and pedagogy, the program uses interactive audio segments that cover the entire preschool math curriculum. Since Paraguayan classrooms tend to be bilingual, the audio and written materials use a combination of Spanish and Guaraní. Based on an experimental evaluation since the program’s implementation, we document positive and significant improvements of 0.16 standard deviations in standardized test scores. The program helped narrow learning gaps between low- and high-performing students, and between students with trained teachers and those whose teachers lack formal training… Continue Reading
