WEB 2.0 in education: Do we really always need it?

We accept interactive technology in the production of e-learning materials. It is not perceived just as valuable addition, but it becomes mandatory in e-learning material production. Therefore all new e-learning materials are either WEB 2.0 enhanced or obsolete. But is this true? We have different types of e-learning materials. Some are for self-learning, other are for blended learning and there are also electronic libraries. In our case we have prepared for the occasion the International year of astronomy 2009 the e-learning material that is fundamental for learning about Galileo´s life and work (available on: http://fizika.dssl.si/Galileo/). It does not have any WEB 2.0 capabilities and because of that it is perceived as more credible than any other e-learning material about this topic for our students. In the article we are going to show the analysis of our material compared to other similar materials which are available over the web; and the results of the survey we conduct among our primary users. In addition, it was tested in a few primary and secondary schools at the end of 2009 in the frame of the national project Development of natural science competences.
