Description of the Experience
There are lots of students who find geometry very difficult because they can’t design and visualize correct geometrical constructions. This calls for a spatial imagination. We used technology to promote students’ understanding of geometry. This offers a more dynamic approach of geometry (as opposed to the paper one which is static. Dynamic geometry is active; it can be explored. It enables students to visualize abstract geometrical concepts. A traditional pencil and paper environment has a limited capacity in introducing a geometrical concept. Dynamic geometry provides students with the option of generating empirical evidence to progress from particular cases to the general case. In addition, a dynamic geometry medium plays an essential role in enabling students to construct geometrical objects and visualize geometrical conjectures or ideas at a perceptive level. There are 3D programmes which can help you a lot.

I have the same experience with students; that for them the geometry is more difficult than algebra. But there are some students which are better at geometry - drawing. Students´ imagination is weak. They often lack the knowledge about basic geometric shapes. It is important for them to be able to know and imagine the geometric shapes. I think that the usage of the dynamic geometry software is very helpful. This way we can explain more and faster in comparison to the classical teaching. I use it on my lessons too. The results of students have improved.

Mám tie isté skúsenosti so žiakmi, že pre nich je geometria ťažšia ako algebra. Ale nájdu sa žiaci, ktorým ide viac geometria - rysovanie. Predstavivosť žiakov je slabá. Žiakom často chýbajú vedomosti o základných geometrických útvaroch.
Je dôležité, aby si vedeli predstaviť geometrické útvary.
Myslím, že použitie softvéru dynamickej geometrie nám v tom veľmi pomáha. Je to rýchly spôsob vysvetliť viac ako pri klasickom vyučovaní.
Aj ja ho používam na hodinách. Študijné výsledky žiakov sa zlepšili.

I think this experience is relevant because it focuses an important problem in our way of teaching plane or solid geometry : many students often find these subjects difficult, sometime even if they have good marks in algebra. During the first two years of secondary school students who are in some difficulty are also lacking in motivation and they don’t enjoy studying geometry any more.
Helping students to design and visualize correct geometrical constructions is the first step.
I think using technology is a good way to improve students’ attention and motivation towards geometry and it promotes a better knowledge and understanding.
I have had a similar experience using a software of dynamic geometry, both in first and in secondary school. I think it can be useful to construct geometrical objects with everyday materials ( like thin canes or others ) to explore some geometrical properties, for example in figures like parallelogram, rectangle or rhombus. After this “physical” experience many students are able to use programmes with more consciousness.


Dissemination Seminar in Florence

31 October 2015 The seminar has been held in ITIS “A. Meucci” one of the schools involved within Goerudio project activities. Its main aim was to promote the results of the project toward a broad sample of stakeholders even overcrossing the number of people directly involved in the production of project outcomes. This purpose has been totally achieved especially thanks to the participation of students and teachers coming from different schools or from other classes instead of those ones directly involved within the project activities.
