Description of the Experience
The aim of this lesson was to rehearse the subject matter of the formation and properties of graphs of functions - linear, quadratic, exponential and power types. Students worked in a computer lab with a computer program called Geogebra. They have already mastered the basics of the program. They were supposed to construct in this program certain graphs of functions according to their formulas. By using the scroll bar they had to verbally describe how the graph of the function varies with changes in the regulation of certain constants in the function formulas. The students were working at the computer individually while they had the same assignment. They had no problem with the design of individual graphs but it was worse with the presentation of these function graphs and description of their properties. Students evaluated this type of teaching (when using computers and programs) as easier than sketching the function graphs in their notebooks. They liked it. Next time I would probably acted differently in the sense that students would not have the same assignment of sketching the function graphs but each student would receive a different type of function. Later he or she would present the result itself in front of his or her classmates. I would also like to add a worksheet in which they would have to respond to different tasks. This would act as a sort of outline according to which they could guide themselves in their oral presentations. I had a good overall impression of the lesson besides the students’ work result presentations, which was caused by the fact that students are not as accustomed to present their results by themselves. On this we still have to work together.

I'm very fond of Geogebra too. I think it's a very good program to study functions. I usually prefer this working method: previously students have to study a given function in an analitical way (using their notebooks and all the concepts studied ), then they test the function with Geogebra and find out if the two graphs agree. In this way I try to teach them the difference between numerical and analitical function studies


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.
