Semipartial geometries, arising from locally hermitian 1-systems of $W_{5}(q)$ - Luyckx, D.; Thas, J. A.
It is known that every 1-system of $W_{5}(q)$ is an SPG
regulus and thus defines a semipartial geometry. In this paper, the semipartial
geometries arising from locally hermitian 1-systems of $W_{5}(q)$, $q$ even,
will be investigated. It will be shown that non-isomorphic locally hermitian
1-systems of $W_{5}(q)$ yield non-isomorphic semipartial geometries, which
implies the existence of new semipartial geometries.

Sobre las formas efectivas de incorporar el software Cabri-Geometrie en la enseñanza de conceptos geométricos en el bachillerato - Bohórquez, Luis Angel
The following literature review attempts to answer the question of how to use the Cabri-Geometrie software effectively for the learning of geometric concepts. It is important to consider this question in order to allow the design of pedagogical practices which effectively support this learning. In the present literature review I summarize research reports, classroom experiences and theoretical documents that support the design of pedagogical practices based on giving the students problems to generate different solving strategies and the use of the program as a natural resource for doing so. This literature also supports collaborative discussion of strategies as an effective...
