Questions for each level of learning

The OpenStax version of Principles of Microeconomics further expands on Taylor’s original end of chapter materials by offering four types of end-of-module questions for students.

  • Self-Checks: Are analytical self-assessment questions that appear at the end of each module. They “click–to-reveal” an answer in the web view so students can check their understanding before moving on to the next module. Self-Check questions are not simple look-up questions. They push the student to think a bit beyond what is said in the text. Self-Check questions are designed for formative (rather than summative) assessment. The questions and answers are explained so that students feel like they are being walked through the problem.
  • Review Questions: Have been retained from Taylor’s version, and are simple recall questions from the chapter and are in open-response format ( not multiple choice or true/false). The answers can be looked up in the text.
  • Critical Thinking Questions: Are new higher-level, conceptual questions that ask students to demonstrate their understanding by applying what they have learned in different contexts. They ask for outside-the-box thinking, for reasoning about the concepts. They push the student to places they wouldn’t have thought of going themselves.
  • Problems: Are exercises that give students additional practice working with the analytic and computational concepts in the module.

Updated art

Principles of Microeconomics includes an updated art program to better inform today’s student, providing the latest data on covered topics.
