With our project T.E.S.L.A. (Technology, Education, Science, Life, Applications) we wish more teachers to learn about Web 2.0 tools in education and use them in their lessons. Additionally, developments in technology are fast and misusing possibility of it is high. We believe that we should follow technological developments as teachers no matter what our field of studies are and show our students how to use them for the benefit of themselves in education, in life and so on.
