Information density

  • Reduce short-term memory load. Do not overload the page with information
  • Ideally, submit one piece of information per sentence
  • Change the page when you change the subject
  • Use a maximum of 2 sentences per line (i.e., 60-70 characters per line)
  • Provide ways in which the student may recognize information, rather than be required to recall it
  • Use indicators such as colour, text layout, shape/texture, and audio to provide contextual clues and easy recognition
  • Be consistent in the use of the indicator: An indicator must signify the same thing throughout the text
  • Use visual cues to highlight important points or sections of the content
  • Remove information the student doesn’t want or need
  • Avoid sounds, animations, and other moving content that are played without the student specifically interacting with the interface
  • Don’t suppose any knowledge to be already acquired by the reader. Describe as much as possible
  • Use examples to clarify complex concepts. Examples help to explain by linking prior experiences with new information
  • Minimize cross-references to other documents, fields of knowledge or events. If the reference is necessary, it is better to join the other document and ensure it also meets the simplification rules
  • Avoid presenting the student with noise stimuli. Extensive use of illustrations, audio background, pop-up windows, etc. may distract the reader
  • Reduce the number of instructions needed for the student to perform the required task
  • Ensure that the procedure for executing a task (e.g. searching on the Web) is always the same
  • Present the student with one instruction at a time. Avoid simultaneous tasks
  • Repeat the instruction each time you refer to it
  • Provide simple reminders such as “step 2 of 4” to help the student keep track of what he has already done and what he has left to do
  • Replace the comma with a newline when enumerating or listing many items
  • Provide the student with clues to estimate the duration of an activity and when it ends
  • Avoid time based events (e.g. auto refresh, redirects, shut outs). Allow the student to interact with the interface at their pace
