Last week, my technical composition students explored the government website Plain Language, which is devoted to clear writing in government documents. The information on the site is useful for anyone interested in finding ways to communicate more effectively (and would make a great homeschooling resource).
You might start with the “Tips and Tools” section for specific suggestions or browse the “before and after” examples of real documents that have undergone “plain language” revision, such as this one:
Before
When the process of freeing a vehicle that has been stuck results in ruts or holes, the operator will fill the rut or hole created by such activity before removing the vehicle from the immediate area.
After
If you make a hole while freeing a stuck vehicle, you must fill the hole before you drive away.
