Aplia™ for A CONCISE INTRODUCTION TO LOGIC, 13th Edition, is an online interactive learning solution that improves comprehension and outcomes by increasing student effort and engagement. Founded by a professor to enhance his own courses, Aplia™ provides automatically graded assignments with detailed, immediate explanations on every question. The interactive assignments have been developed to address the major concepts covered in the text and are designed to promote critical thinking. Aplia™ includes new supplemental exercises to provide extra practice with difficult topics such as propositional logic and predicate logic. There's also a new "indirect Truth Table" allowing for multiple correct paths to completion of this logic problem type. Students get immediate feedback on their work (not only what they got right or wrong, but why), and they can choose to see another set of related questions if they want more practice. A searchable e-book (MindTap® Reader) is available inside the course as well, for easy reference. Aplia's™ simple-to-use course management interface allows instructors to post announcements, upload course materials, host student discussions, e-mail students, and manage the grade-book. A knowledgeable and friendly support team also offers assistance in customizing assignments to the instructor's course schedule. For a more comprehensive, all-in-one course solution, Aplia™ assignments may be found within the MindTap® Philosophy digital learning solution.
