Critical Thinking and Logic

Critical Thinking and Logic

Critical Thinking and Logic provides an introduction to the construction and evaluation of arguments. This learning resource contains a discussion of critical thinking and its relevance in everyday circumstances. Students learn to distinguish between statements of preference and reasoned opinions, and they gain the tools necessary to determine whether they should or should not be persuaded by particular arguments.

Students evaluate inductive arguments for strength and good reasoning, deductive arguments, and first-order logical symbolization, as well as informal fallacies of relevance, presumption, and ambiguity. Students learn to identify both tacit and implicit assumptions, and they are introduced to criteria for examining the reliability of evidence presented in support of conclusions. In the sections devoted to formal arguments, students have the opportunity to create truth tables, and construct proofs.

Games, videos, and other interactive elements motivate students to progress while reviewing the various types of arguments and methods of evaluation. Printable module summaries provide a brief, consolidated review of the key concepts introduced in each module.
