Aufmann's Discovering Mathematics: A Quantitative Reasoning Approach with WebAssign is designed for today's Quantitative Reasoning course. By focusing on topics relevant to students and helping them develop critical-thinking skills they can apply beyond the course, this solution provides students with exactly what they need, in an approachable, engaging, and streamlined format. Customizable for use inall teaching models—from lecture, hybrid, or fully online to flipped and active learning environments—Discovering Mathematics: A Quantitative Reasoning Approach will empower you to accomplish all your course objectives.

Features & Benefits:
  • Prerequisite Material: Assignable Coursepacks provide a refresher of basic algebra concepts, allowing students to confidently approach more concrete and applications-based quantitative reasoning topics.
  • Short Projects and Investigations: In addition to providing good opportunities for group work and class discussion, these activities, taken from the text, also guide students on how to navigate and organize their work. They are assignable, gradable, and responsive to student input. Students enter their own values and are graded based on their input.
  • Online Appendices: These appendices give a narrative overview of appropriate algebra concepts, providing examples and practice aimed at preparing students for more conceptual assessments and discussions.
  • Class Insights: WebAssign gives you an analytical view of your students' performance on questions and topics throughout the course. Use Class Insights to tailor your classroom discussions to review topics your class may not understand, or identify specific students who may need extra help.
  • Timely Help: Robust Help functionality promotes independent learning with a wide range of tools at the question or assignment level—such as Watch It videos, Master It tutorials, and Read It links to the ebook—and feedback right when students need it to complete assignments and learn the concepts.
  • Teach Your Way: Fully customizable settings including automatic point adjustments and browser lockdown empower you to build the course to your needs and keep students motivated.
