Requirements on a Mathematical Notation for the Blind
نویسنده
چکیده
The integration of blind people into learning and working environments of the sighted needs among other things a possibility to write and represent mathematical expressions in an appropriate way. There exist different concepts how to form a mathematical notation for the blind. This contribution presents in a first step a discussion of the variety of demands for a mathematical notation. In a second step it is shown that the "Stuttgarter Mathematikschrift für Blinde" (SMSB) meets these requirements. Particularly it is possible to transform SMSB-terms into a graphical representation, which is familiar to the sighted.

Blind students have limitations that their teachers have to apply efficient educational methods for them. Since mathematics concepts are abstract for blind students and they cannot understand these concepts deeply, this research has tried that used and introduced cooperative learning method for this reason. Blind students have high listening capacity then cooperative learning method can pro...

For visually handicapped people virtual learning environments are a chance to participate in scientific education, because they can access the written content. However mathematical expressions rendered as raster graphics are not accessible to them. MathML, the web-standard for mathematical notation, provides the possibility to describe mathematical expressions in a textual form. However, it is ...

Let $mathcal {N}_G$ denote the set of all proper normal subgroups of a group $G$ and $A$ be an element of $mathcal {N}_G$. We use the notation $ncc(A)$ to denote the number of distinct $G$-conjugacy classes contained in $A$ and also $mathcal {K}_G$ for the set ${ncc(A) | Ain mathcal {N}_G}$. Let $X$ be a non-empty set of positive integers. A group $G$ is said to be $X$-d...

Introduction: MICAP is a new notation in which the teeth areindicated by letters (I-incisor, C-canine, P-premolar, M-molar)and numbers [1,2,3] which are written superscript and subscripton the relevant letters. FDI tooth notation is a two digit systemwhere one digit shows quadrant and the second one shows thetooth of the quadrant. This study aimed to compare the short termretention of knowledge...
