The Power Point content which was supplied is to be included in the DVD as well as on the website so that it is readily available to the students (computer/internet not required). A simple linear structure would be appropriate (simulating the ppt structure). The buttons "Previous" and "Next" navigate from page to page and a return button can take you back to the last menu. This navigation style is very simple and easy to use. It is not great for skipping many pages (eg. trying to get from slide 2 to slide 16 - "Next" has to be clicked fourteen times ) however, this sort of use would probably be quite rare. It would be best if lecture slide shows had relatively few slides (one which was supplied had over 100!) However, it seems to cover many topics and could therefore be divided into a series of shorter slide shows or chapters. This should be easy to create on Adobe Encore by making each page or slide a separate menu and linking each page by the 'next' and 'previous' buttons.
