We describe a model of the human eye that incorporates a variable converging lens. The model can be easily constructed by students with low-cost materials. It shows in a comprehensible way the functionality of the eye's optical system. Images of near and far objects can be focused. Also, the defects of near and farsighted eyes can be demonstrated.

Current reform in mathematics teaching and learning is rooted in a changing vision of school mathematics, one that includes constructivist learning, student-centered pedagogy, and the use of worthwhile tasks (National Council of Teachers of Mathematics, 1989, 1991, 2000). This changing vision not only challenges teachers' beliefs about mathematics…

This article explores the importance of vision in dance from both the teacher's and the learner's perspectives. Since vision does not function in isolation, the interplay between sight and other modes of learning movement-based material is considered as well. Movement activities are provided to assist with understanding this information…

The use of functional vision by school-age students who have visual impairments, including those with additional disabilities, is typically reported by teachers of students with visual impairments. Functional vision assessments determine how well a student uses his or her vision to perform tasks throughout the school day. The information that is…

The process of change in any organization must begin at the top. Leadership experts describe successful organizations as those that are guided by a leader who exhibits appropriate behavior and vision for the organization and its employees. In other words, leaders must model the behavior and attitudes they want to see from staff members. Therefore,…

A brief overview of the 2007 National Federation of the Blind-Jernigan Institute Youth Slam Chemistry Track, a course of study within a science camp that provided firsthand experimental experience to 200 students who are blind and low-vision, is given. For many of these students, this was their first hands-on experience with laboratory chemistry.…

The efficiency of teaching algorithms can be highly improved by utilizing the senses as educational aids. The authors have developed a new didactical method and a software tool which exemplifies, for the case of simple algorithms, how the involvement of eyesight, hearing and the kinaesthesia can help in the teaching and learning process. This…

The article describes a sequential training curriculum in the use of telescopic visual aids. The curriculum covers 29 topics, including aid maintenance, holding aid properly, focusing, scanning, target location, tracking, aid use for city bus travel, in a shopping center, and in a fast food type restaurant. (Author/SBH)

A comprehensive program of instruction in the use of low vision is proposed, including definitions, a philosophy of low vision, theoretical constructs, a flow chart of professional and individual relationships and responsibilities, goals, curriculum, and an evaluation system. (Author/JDD)

A project was developed which successfully taught individuals with visual impairments to read commercial large-print books, with either their own reading spectacles or with lower levels of magnification than usually prescribed. Over the course of the project, print sizes were systematically reduced and healthy reading habits were re-taught. (JDD)

The initial role of the low-vision teacher involves helping patients psychologically adjust to their situation and assessing patients' readiness for rehabilitation. Then training can begin to effectively use remaining vision, to determine fixation angles for reading text, and to function both with and without optical and other aids. (JDD)

The author discusses the advantages and made to measure microcomputer programs for the partially sighted student. Several strategies for using the microcomputer in the classroom are suggested. (SW)

A closed-circuit television system was used with a five-year-old girl with severely limited vision to develop visual skills, especially skills related to concept formation. At the end of training, the girl could recognize lines, forms, shapes, letters, numbers, and words and could read short sentences. (Author/JDD)

A volume in the "Dimensions in Early Learning Series" this monograph proposes suggestions for parents and teachers to supplement normal classroom procedures in the area of visual learning. Chapter I concludes that a child's development of visual skills is directly influenced by inborn tendencies, physical characteristics, and environmental…
