Course Scientific Writing : Geoff Hyde (National Centre for Biological Sciences, Bangalore) developed an online course Scientific Writing in which Rationale is fully integrated.

From the Introduction:

‘Rationale is mainly focussed on teaching people how to think clearly about contentious issues, and has very successfully popularized a diagrammatic method of argument development.
My experiences in the classroom have taught me that this diagrammatic approach is also a great starting point for writing all types of scientific text. It is the most practical way to outline that I have come across. Outlining is often promoted as a writing tool because it forces the writer to focus first on organising ideas, before moving onto packaging them.’
