Astronomy has an interdisciplinary aspect that in some cases is very positive. It is interesting to combine Astronomy with other topics and introduce Astronomy in general projects in school in order to integrate several courses, for instance Physics, Mathematics, Geography, Biology or History; however these kinds of projects are sporadic. In order to promote Astronomy it is better to try to introduce it as a course in its own right. The viability of this situation depends on the national curriculum and the plans of the Education Ministry in each country. In general, the majority of countries do not have Astronomy as a specific course and it is not easy to achieve. Therefore, if this option is not possible, we should adapt to the real situation, that is to say include Astronomy as a part of other courses. This contribution aims to propose a new point of view which could work to make this the case.
