Description of the educational product

The educational product is addressed to upper secondary school students between 14 and 15 years old. The aim of an educational model is to illustrate a scientific concept through an image that has been chosen by a student. In this specific model the concept of diffusion is explained. Once the model has been developed, the student presents it to the classmates asking for their opinion about the usability of the model itself. The discussion, moderated by the teacher, is a training moment and a good opportunity for him to explain the scientific concept and also evaluate the students’ interaction. The student himself also translated the model, which is training of his language skills in the specific matter. The expected results from using this model would be better comprehension and understanding of a scientific concept, stimulation of the creative thinking of the students, improving their discussion and assessment abilities.

Few models are actually perfect for the phenomenon tried to be explained. This model also has its drawbacks. Specifically, The model is "static", compared to the "dynamic" change that happens in the real phenomenon. However, the students can easily understand that the model is perfoming like the real phenomenon only when the bag is being shaked. If the student stops the motion, The model is not such. Other than this issue, the model is very very good, as the studen can "see" the phenomenon

This product is not so good for studying diffusion, because they are using solid fixture which don't have fast reaction. This model is very simple, so I suggest to use it for younger students.

Good demonstration of diffusion.But the problem is that it is static.Diffusion is motion of molecules or particles.But if you shake them and said that you heat them ,it will be a good model.
I tray it in may lesson ,physics lesson ,and it works well.

The diffusion is a very abstract topic because it is related with Chemistry and implicitly with our daily life. It may seem hard to understand in the instance but when students see an experiment it will be all clarified. I will also apply it to my students but I will ask them to take observation at home and then present it in front of the class next day. Maybe this will also imply some debates and this way they will fill their knowladge's gaps.

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.
