Geometry and optical illusions

Author: Daniela Leone

Methodology and tools

This is a remote learning activity, developed in March 2020 with 1st-grade students of IC21 Bologna lower secondary school.

The tools used are GSuite for Education, GeoGebra and Go-Lab resources. The activity is based on Inquiry-based Learning methodology.

Students had a little experience with GSuite, Go-Lab and GeoGebra but no experience of learning from home. To be able to communicate we used GSuite tools (email, tutorials on Google Classroom, Google Meet calls).

The Go-Lab Inquiry Learning Space used for the activity is a translated version of the French ILS “Changer de perspective” created by Valentin Roussel.

Activity

Thanks to the author, the ILS was useful to guide students in discovering basic geometry in a playful way: it aroused their curiosity about the features that add special effects to images. The questions helped students to reflect and recognize the main properties of parallel and perpendicular lines, angles, areas, by manipulating dynamic figures. The images included in the ILS were inspiring for students.

At the end of the translated version made for the IC21 school, I added an extra task for my students: they were asked to make and share their own images containing optical illusions or special effects, using the GeoGebra Geometry App.

Symmetry in Mathematics and Art

On April 23, 2019, the topic “Symmetry in Mathematics and Art” was presented at Teodor Trayanov’s 10th School in Sofia. During the hour Neda, Koya and Toni introduced the students of the 5th grade with several types of symmetry in mathematics and art. With the help of dynamic resources created with Geogebra, the pupils made an author’s works.

Glass exhibition “OpArt”

A glass exhibition called “OpArt” will be held at the New Bulgarian University. For the creation of the works, the author has used knowledge in the fields of mathematics and IT. The doors of the glass studio of the New Bulgarian University open wide, welcoming students and anyone who wants to get acquainted with different types of glass techniques and treatments.

Online competition “Mathematics and Art: Shadow”

It is a specific online competition, which connects mathematics, IT and art. The purpose of the competition is to develop key competences and popularise  mathematical instruments in front of a wide audience. The competition is a motivating tool for students to learn new knowledge and create their own environments and artworks.

To enter the competition you must fill in the data and attach an author’s photo or a dynamic file. There is no limit to the number of models that anyone can participate in. Each entry is self-registered. There are no age restrictions for the participants. After the deadline for participation, the works will be displayed in a voting gallery. There is a limit for voting from one address to 1 time a day. At the end of the second stage, the winners selected by the jury as well as the most liked work from the audience will be announced.
