摘要:Free software applications are available for most computing tasks. This article presents three examples of free software and describes how they could be useful to an Extension educator. The applications discussed in this article are Freemind, Doodle, and KPlato Project Management. Freemind is a concept-mapping tool. Doodle makes online polling easy, especially for scheduling events with multiple people. KPlato Project Management allows users to create and manage project plans. By using at least one of the three software applications discussed here, Extension educators should be encouraged to explore other free applications.
