Thanks for your contribution, Petr. I will tell you how I see it. I agree with you that we should take into account teachers' needs before starting a project since any funded project is addressed to specific stakeholders' needs or problems. However, although projects' outcomes addressed these needs, the dissemination plan could not take into account aspects as which are the channels that teachers prefer or which characteristics (language, format, length, duration, cost, etc) facilitate teachers' engagement and understanding.
For example, let's say that one project's outcome consisted of a teaching and learning virtual environment with a repository of activitites addressed to facilitate the introduction of socioscientific issues in the science class. Which actions should this project carry out to disseminate these outcomes to a certain number of teachers? In case, the project had a budget for organising face-to-face workshops, which would be a suitable format for helping teachers understand and use this product? And in case the dissemination should be done through online courses?
I consider that there are also some specific needs to take into account when talking about dissemination plans.
