With fresh insight from new co-author Andrea Campbell, 我们人类, Twelfth Edition, once again sets the standard for showing students how government impacts their lives and why it matters who participates. Campbell relates true, personal stories of how government affects ordinary citizens. This focus is reinforced by the book’s signature “Who Are Americans?” and “Who Participates?” features which motivate critical thinking about how Americans experience and shape politics. Learning goals ensure that students maintain consistent focus on core concepts in the text, in its companion InQuizitive learning tool, and in supporting critical-thinking exercises.
