Unit Zero – Sample Unit

Introduction Normal units
 
A normal unit consists primarily of pages of text. Many people find reading from a screen very difficult and so it might be argued that text is best presented in the form of a document that can be printed off and studied like a book. However a normal unit is more than just text, and there are at least two ways in which it is a much richer experience than reading printed matter:
  • Text is presented in a number of different formats that provide more variety and encourage closer engagement with the material than the rather passive activity of reading printed words.
  • Text is supported by audio, interactive images, links and tasks.

Normal units provide opportunities for reflection and formative self-assessment with the use of Exercises and Tasks. They are described below.
