Technologies And Tools In Teaching Mathematics To Visually Impaired Students

In this paper we describe the effort of the Support Centre for Visually Impaired Students in Bratislava to design an effective and helpful digital tool for learning and teaching mathematics to visually impaired students. In the first phase of our research methodology, which follows the design-based approach, we focus on mapping of the actual situation of teaching math to those students at each level of education in Slovakia. The emphasis is placed on tools and technologies these students use, as well as on problems that occur when using these tools. Later on we focus on LAMBDA editor, which seems appropriate for learning and teaching math to those students. Its adaptation to local conditions, which consisted of several iterative cycles of analysis, development, evaluation and revision, is reported in the second part of the paper.
