Description of the Experience
The equation ax2 + bx + c = 0 where a ≠ 0, b and c are real coefficients is called quadric polynomial.
When a=0 the polynomial turns into linear and then it has one root. When a ≠ 0 the expression D = b2 – 4ac is called discriminant. Sometimes it’s difficult for the students to remember the expression for the discriminant. In order to facilitate remembering I tell them the formula not with mathematical terminology (which is necessary) but with their student jargon which they use in their communication with other students. In their short messages they use the number 4 instead of letter ‘ч’. In this way the part of the expression of the discriminant ‘4ас’ sounds like the word ‘hour’. Telling them this way the formula they remember it and apply it easier when they need it.

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.
