illocutionary development

[misspatty]

I need to know what is cohesion and propositional development and coherence and illocutionary development.

Can anyone explain to me?

Where can I find some information about that?
Where can I find the book: Teaching Language as Communication
by H G Widdowson?

I appreciate your support. Thank you in advance.

Widdowson: you will find many copies here: AbeBooks: Search Results - widdowson and Teaching Language as Communication

Have you googled these? I found lots of references using the keywords "propositional development" and "illucutionary development". Again, Google Scholar might be the better source.
