Lesson plan

1 Netsearch: optical illusions (15 min.)

Students use search engines to find optical illusions in order to illustrate that (modern) graphical artists too, are interested in the dilemma instinct-rationality and demonstrate how easily the mind can be fooled. Each student selects an illustration for his temporary file, which can be used to make a link with DHL and his motto: "We can go wrong in our minds..."

2 Group assembly and exchange of information (15 min.)

3 Completion group document (15 min.)

A lot of optical illusionists, the most famous of whom is Maurits Cornelis Escher (born June 17th, 1898 in Holland and died in 1972), made works of art to show that one cannot trust one's logic in all circumstances.

How remarkable that people may get the same visual impulses... but come to different conclusions. In the first drawing some see a naked woman and others see the face of a man... In the second drawing some recognize a young girl, others an old lady... It may be hard to force some minds to see what you see and what you think is so obvious to see!
