Foundation: Studying the Concepts Updated - Structured, yet flexible, the updated learning path highlights author-created, faculty-vetted content — giving students what they need exactly when they need it.  The learning path directs students to resources such as videos and animations for just in time support. New - Just-in-Time Review modules at the beginning of the text and etext review the key topics from previous courses that are prerequisites for the new material in this course. Just-in-Time Review Videos in MyLab Math offer a concise presentation of each topic with additional examples. New - Skill Review, in nearly every section of the text and etext, reviews a previously presented skill at the objective level where it is key to learning the new material. In MyLab Math, Skill Review Videos, created by the authors, offer a concise, stepped-out solution for each Skill Review Exercise.  New - Chapter Opener applications with graphics use current data and applications to present the math in context. These applications are linked to exercises in the text and MyLab Math course to help students model, visualize, and learn the math.  New - Student Activities begin with real-world data and guide students to examine a key concept in each chapter, while analyzing the data and connecting other concepts. There is one activity per chapter and they are available in MyLab Math and in the printed MyMathGuide. New - Interactive Animations, available in MyLab Math, allow students to examine visual representations of concepts through both guided and open-ended exploration to further solidify their understanding of these concepts. New - Bittinger-specific Learning Catalytics questions are now available. Learning Catalytics is an interactive student response tool that uses students’ smartphones, tablets, or laptops to engage them in more sophisticated tasks and thinking. Application: Reinforcing Understanding New - Check Your Understanding with Reading Check and Concept Check exercises at the beginning of each section exercise set gives students the opportunity to assess their grasp of the skills and concepts before they move on to the homework. Margin Exercises give students frequent opportunities to apply concepts just discussed by solving problems that parallel the text Examples. Section Exercises, including Skill Maintenance, Synthesis, and real-data Applications, offer abundant opportunities for practice, review, and development of critical-thinking skills. New! Guided Solutions exercises were added to MyLab Math to reinforce the step-by-step problem-solving process, while the new Drag & Drop functionality was applied to matching exercises throughout the course to better assess a student’s understanding of the concepts. Retention: Carrying Success Forward New - Skill Builder offers adaptive practicethat is designed to increase students’ ability to complete their assignments. By monitoring student performance on their homework, Skill Builder adapts to each student’s needs and provides just-in-time, in-assignment practice to help them improve their proficiency of key learning objectives. Mid-Chapter Review with Concept Reinforcement, Guided Solutions, Mixed Review, and Understanding through Discussion and Writing allows student to pause and actively review halfway through the chapter in the text and MyLab Math Summary and Review is a comprehensive learning and review section at the end of each chapter with Vocabulary Reinforcement, Concept Reinforcement, Study Guide, Review Exercises, and Understanding through Writing and Discussion exercises. Chapter Tests, Chapter Test Prep videos, and Cumulative Review offer additional opportunities for review and reinforcement of skills and concepts in the text and MyLab Math.
