Scroll or paginate?

Having a debate with a colleague about scrolling or pagination, specifically in elearning modules.  I’m a fan of the styles of Cathy Moore or Presentation Zen – as few words as possible making as strong a message as possible. When you’re dealing with subject experts it’s a struggle but one I enjoy engaging in.  When I approached colleagues for their wish list for a new template I’m designing (for page-turners) he said what he wanted was ‘more space to display content’. When I queried it he said there was research – in Australia, he thinks – that concluded users prefer to scroll down to read information than page through many pages of short texts.  I’m wondering if this was specifically research on tutorial-style elearning or was it for reference information (in which case I agree.)

Can anyone point me to the actual research report, or to any useful writing on the subject?
