Reasoning of pupils in the solving process of a geometrical inquiry-stimulating task
Roubíček, Filip
The poster focuses on the issue of solving geometrical problems in the context of inquiry based education, namely on the use of inquiry by pupils and on classroom mathematics discourse. The poster describes communicative situations in solving of inquiry based problems and presents examples of pupils’ solutions and discussion in the classroom.
Geometrical constructions and regular mosaics
Roubíček, Filip
In the teaching of geometry regular mosaics represent a suitable environment for developing of geometrical imagination and constructing procedures based on the use of isometries in plane. Mosaics are plane tesselations, i.e. coverages of plane by (in most case identical) shapes without gaps and overlaps. The construction of a geometrical mosaic follows from a shape of tiles and their assembling. Analyse of a mosaics is based on identification of its grid and a construction of tiles.
Geometrical imagination as a part of mathematical literacy
Roubíček, Filip
The paper deals with geometrical imagination as ability to interpret geometrical content, evoke images and manipulate with them. It describes approaches to teaching of geometry at primary school (natural geometry, principles of didactical structure of geometry) and activities for development geometrical imagination of pupils.
O jednom geometrickém prostředí podporujícím přirozenou differenciaci
Macháčková, Jana ; Roubíček, Filip
The poster deals with development of geometry thinging at primary school level and motivation of pupils via natural differentiation. The learning environment that is based on describing and drawing a way in a plan is illustrated.
Geometrical modelling
Roubíček, Filip
The paper deals with the problem of representation of geometrical objects by means of material models. It includes the description of two methods of modelling in planimetry: geometry of folding paper and geometrical puzzles.
Různé formy modelování jako podpora komunikace mezi učitelem a žákem
Roubíček, Filip
The poster includes some illustrations of representational environments investigated in the frame of mathematics classes at an elementary school, for example usage of various types of puzzles, geometry of folded sheet of paper and geometry using strings.
Rozmanitost reprezentačních prostředí v primární geometrii
Roubíček, Filip
The poster concerns the problem of representations in the teaching of geometry. It describes an experiment that was carried out with the aim to observe influences of different forms of representation on pupils´cognition.
Geometric constructions from the point of view of various didactic environments
Roubíček, Filip
The paper describes three didactic environments as an alternative to drawing. They concern constructions of geometric figures using puzzles, folding paper and using strings. These representational environments are presented on constructions of polygons.
Reprezentace jako faktor ovlivňující prostředí vyučování geometrii
Roubíček, Filip
The paper deals with the problem of representations and their roles in the teaching of geometry. Three specific representational modes - representation of a problem through a story, non-verbal representation and geometrical sketch - used in a didactical experiment are described.
Geometrical competences and their evaluation in the mathematics teaching
Roubíček, Filip
The paper deals with the cultivation of competences to orient in space, to distinguish and to represent geometric solids in primary school. Some pupul´s activities, methods of model representation and didactic games aimed to cognize geometric solids are described.
