This software was designed by professor Austen Clark, at the University of Connecticut. The first program, Twootie, is particularly relevant to Meaning and Argument as it deals with truth trees. The second program, Bertie3, focuses on natural deduction. For background information on the software, visit the Twootie and Bertie3 Home page.
Students working with Meaning and Argument are encouraged to use Twootie, in addition to practicing truth trees by hand. The program offers helpful hints, and is a great way to become more familiar with truth trees. Bertie3 offers support for the student who wants to learn more about natural deduction.
