Description of the Experience
This experience has been performed in a four year High School Course (17-18 years old students).
In an Analytical Instrumentation Chemistry Course there is a lot of
information to remember, especially for huge subjects as Chromatography:
several different techniques, chemical laws and principles, a big amount of
information about stationary and mobile phases (different sets of it for
normal and reverse phase chromatography), other information such as
different types of injection and/or detection devices, and so on. This
kind of information is not easy to handle and difficult to remember. So I
started to think to a way to make easier this task.
The better way I found was to make students work in groups (3-4 membered
groups) and I selected different techniques to work with, than I assigned them to each group. To make work harder and more stimulating I made two groups work on the same subject at the same time. They had to select information from the book and from the Net, and, in a second time, built up a computer presentation with slides. The work was done in three different steps:
1. In class, working in group and selecting materials and plan the project work;
2. In the computer room, doing the first part of computer work;
3. At home, doing the final part and afterwards sending the work by
e-mail or giving the presentation to teacher at school. There is another important step: presenting the work to the teacher and to classmates.
The final evaluation involved a group evaluation of: a) group work organisation, b) evaluation of the digital product, c) evaluation of oral presentation.
At the end of work a test exam has done to assess the individual comprehension of the subject, giving sufficient to good results.

A very important thing for the group work is to assign a precise job to everybody. The most important job to assign is that somebody has to draw everyone attention to work and remember to the others to be quiet; another key task is to pay attention to the watch, making sure there will be results in the assigned time.

Dear Chiara, thank you for your positive evaluation. I planned and proposed this work to a weak class, one you expect that cannot afford a very deep study on a difficult subject. Anyway I think that every kind of class/ student can have an opportunity of better results if stimulated in a proper manner.
Another point was that in our School there aren't a lot of resources to learn more practically some techniques.

This experience is relevant because it helps the students to build up their knowledge through traditional and online research. Moreover it aims to provide the students with a methodology based on the sharing and the responsibility.
This experience explains the causes of the lack of motivation towards the study of the scientific subjects. It tries to overcome them with a direct involvement of the students and not having them as spectators.
Many teachers of scientific subjects have, certainly, faced with the low motivation issue. I am used to it. This issue often affects a few number of students, but sometime the teacher deals with an entirely apathetic class. In these last cases it is absolutely necessary to find new communicative strategies. The use of ICT certainly helps to support this scope.


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.
