The Efficacy of Designing a Human versus Automated Voice Advance Organizer within an E-Book on Developing Some Scientific Concepts among Visually Impaired Students in Tripoli – Libya

Abstract

The aim of the current research was to investigate the effectiveness of an advanced electronic organizer designed with two audio modes in an e-book, and to measure their impact on developing some scientific concepts among eighth-grade visually impaired students at Al-Noor Institution for the Blind in Tripoli – Libya, specifically in the unit 'Digestion in Animals' from the science curriculum. The research relied on the developmental method and applied an experimental design based on two experimental groups with pre- and post-tests. The research sample consisted of 10 students, randomly and equally divided into two groups: the first experimental group studied using the advanced organizer with automated voice, and the second experimental group studied using the advanced organizer with a human voice. The research tool was an achievement test, and the experimental material (the two e-books) was designed based on the 'Abdel Latif Al-Jazzar (2002)' instructional design model. The results showed a balance between the two groups in the pre-test and showed clear effectiveness for both audio modes in the post-test, with the students in the second experimental group (human voice organizer mode) outperforming by achieving an average score of 49.00.Compared to the students in the first experimental group (the advanced organizer with automated audio) who achieved an average of 46.00. In light of these results, the study recommended expanding the production and development of e-books based on audio technology and multimedia curricula adapted to meet the needs of visually impaired students at different educational levels.
