Background: Reading failure is far higher among disadvantaged students than among other students (National Center for Education Statistics, 2019). Many attempts to solve this have focused on schools, yet non-school factors have a substantial impact on learning (Clabaugh, 2008). One of these is uncorrected vision. Approximately 20-25% of school-age…

This article investigates the optics conceptions of 228 Thai high school students in grades 10-12 when they attempted to explain how an object can be seen both in general and in a completely dark room. To elicit students' conceptions precisely, their confidence in giving reasons for the final two diagnostic questions is also considered. The study…

This study aimed to develop a valid and reliable instrument that measures the functional vision of students with low vision. Thus, an assessment tool and performance activities were developed for three vision skill groups (near vision skills, distance vision skills, and visual field) that include functional vision skills. The universe was 1485…

This study aims to find out how society views vision impairment (VI) by bringing it closer to citizens through a specific strategy to encourage contact and dialogue with people with VI. A 'Human Library' was developed in which 14 people with or related to vision impairment discussed their experiences and concerns with 52 citizens without vision…

During the 2016-2017 school year, the Vision Partnership program provided vision services to approximately 3,353 students enrolled in the Houston Independent School District. This evaluation brief describes HISD students' participation in campus-based screenings and the Vision Partnership, and the academic achievement of students served by the…

Background: The development of context-based science curricula has been identified as one of the most effective curricular innovations to develop interest and better conceptual understanding of many areas in science. However, such a curriculum can be more fruitful if it starts with the assessment of learners' contextualized knowledge about the…

Vignette design has been largely neglected in anchoring vignette studies. This study aimed to contribute to the science of vignette design by developing and evaluating vignettes for measuring vision in rural China. Cognitive interviews were conducted among 36 participants in a Chinese middle school. The respondents either directly evaluated vision…

This study evaluates the effectiveness of an intervention programme administered to blind and sighted school students. The students were given information concerning style, author and technique of three paintings from three different artistic periods, as well as guidelines to assess the overall aesthetics of each image. This programme was…

This paper shares findings from a post-intentional phenomenological study aimed at understanding learners' experience investigating space and dimension concepts in a fifth and sixth grade mathematics class. Findings indicate experiences in this study manifest as an ontological "trying-on" of geometric dimensions (e.g., through sight,…

Introduction: Research to date on social support for adolescents with visual impairments (that is, blindness or low vision) has been primarily carried out in developed countries, and very little is known about the social support systems that are available for such adolescents in developing countries such as those in the Arab world. In the present…

One day, over four centuries ago, Daniele Barbaro, a Venetian nobleman, tried an interesting experiment (Upton & Upton, 1980). He decided to use a convex lens from a farsighted man's spectacles to expand the viewing power of his camera obscura. To his delight, "the lens projected images much superior to those previously supplied by the…

Current educational practice tends to ascribe a limiting vision of the good student as one who is well behaved, performs well in assessments and demonstrates values in keeping with dominant expectations. This paper argues that this vision of the good student is antithetical to the lived experience of students as they negotiate their positionality…

This article aims at providing insight into ways of constructing leadership for learning within a Norwegian context. The focus is on how a Norwegian principal talks about educational leadership and learning. The principal's story is juxtaposed with references to how her deputies and a group of teachers frame their experiences about leadership for…

This article presents an overview of driving for adolescents and adults who meet their states' visual requirements for low vision driving using bioptic lenses. It also discusses the outcomes of two studies of bioptic driver education.

Many simple experiments can be performed in the classroom to explore the physics of vision. Students can learn of the two types of receptive cells (rods and cones), their distribution on the retina and the existence of the blind spot.
