Deductions for Mac Publisher's description
from Wandering Mango
Logic software designed to help students learn and construct natural deduction proofs in formal logic.
Educational software designed to help students learn proofs in formal logic. It is intended to be used by instructors and students of college-level logic courses in philosophy, mathematics and computer science. It gives immediate feedback at each stage of a proof, provides hints about how to complete proofs, and comes with a set of video tutorials that explain and review several challenging concepts in logic.
Deductions aims to solve the three problems that make proofs the most difficult component of formal logic courses: not knowing whether rules are applied correctly, getting stuck in the middle of a proof, and uncertainty about the rules and strategies. Deductions addresses these issues by flagging errors, including a hint engine to make suggestions about how to complete a proof, and having multimedia tutorials to help students through complex rules.
What's New in This Release:В· Sees the addition of 45 new rules and aliases, to bring the total number of rules supported to 85 (!), with each rule being able to be turned on and off individually.
Expanded the number of textbooks supported вЂњout of the boxвЂќ to ten:
