• Alan S. Tussy

  Alan Tussy has taught all levels of developmental mathematics at Citrus College in Glendora, CA. He has written nine math books. An extraordinary author dedicated to his students' success, he is relentlessly meticulous and creative—a visionary who maintains a keen focus on the greatest challenges students face in Mathematics. Alan received his Bachelor of Science degree in Mathematics from University of Redlands and his Master of Science degree in Applied Mathematics from California State University, Los Angeles. He has taught across course and curriculum areas from prealgebra to differential equations. He is currently focusing on teaching courses related to Developmental Mathematics. Professor Tussy is a member of the American Mathematical Association of Two-Year Colleges (AMATYC).

• Diane Koenig

  A nationally recognized educator and author, Diane Koenig actively shaped several textbooks, ancillaries and series. Since 1982 when she helped develop the Gustafson/Frisk series to her work on the Tussy/Koenig/Gustafson series, Diane’s writing continues to reflect the expertise she gains from working with students in her Mathematics courses. Throughout her work, she integrates research-based strategies in Mathematics education. She earned a Bachelor of Science degree in Secondary Math Education from Illinois State University in 1980, and began her career at Rock Valley College in 1981, when she became the Math Supervisor for a newly formed Personalized Learning Center. Earning her Master's Degree in Applied Mathematics from Northern Illinois University in 1984, Diane, enjoys the distinction of being the first woman to become a full-time faculty member in the Mathematics department for Rock Valley College. In addition to being awarded AMATYC's Excellence in Teaching Award in 2015, she was chosen as the Rock Valley College Faculty of the Year by her peers in 2005, and the next year she was awarded the NISOD Teaching Excellence Award and the Illinois Mathematics Association of Community Colleges Award for Teaching Excellence. In addition to her teaching, she is an active member of the Illinois Mathematics Association of Community Colleges (IMACC), serving on the board of directors, on a state-level task force rewriting the course outlines for the Developmental Mathematics courses, and as the Association's newsletter editor.

• JUST IN TIME SUPPORT built into questions contains direct links to the eTextbook (Read It) and videos (Watch It).

• LEARN IT MODULES address your students’ knowledge gaps with just-in-time instruction that meets their diverse learning styles. Available as an additional resource within questions, Learn Its provide targeted instruction and practice on that topic using narrative, videos and tutorials—all in one place. If the topic is still too challenging, students can choose to continue learning through associated prerequisite Learn Its until they feel confident in their knowledge and preparedness.

• RESPONSIVE QUESTIONS personalize the learning experience for your students by asking them to use their own real data, which provides the variables they will use to answer each question part.

• CONCEPT CHECK questions provide students with short, multi-step videos reviewing key math concepts. Students are required to answer a question after each video to ensure their understanding of each concept.

• EXPANDED PROBLEMS include intermediary steps to guide students to the final answer.

• MASTER IT TUTORIALS break problems down into steps to help guide students through the mathematical process.

• VIDEO EXAMPLES provide embedded videos paired with follow-up questions to ensure student understanding.

• COURSE PACKS are modifiable, ready-to-use assignments built by subject matter experts to help save time.

• CLASS INSIGHTS provide understanding of student knowledge gaps.

• FROM CAMPUS TO CAREERS chapter openers highlight vocations requiring a variety of mathematics skills. The job outlook, educational requirements, and annual earnings data provide practical information to help students make career decisions.

• STUDY SETS are enhanced with application problems that give students appropriate context for the topics they are studying and how they apply in a variety of occupations and vocations.

• STRATEGY AND WHY explanations to the solution of each worked example provides a concise answer about why a particular approach is taken.

• NOW TRY problems complete the final step in the learning process. They appear after each worked example and are linked to a similar problem found within the Guided Practice section of the Study Sets. PRACTICE PROBLEMS address every topic within each section and maintain a clear progression of level. The Practice section is divided into two categories: Guided Practice and Try It Yourself. Guided Practice takes each practice problem and keys it directly to the appropriate example in the section. Try It Yourself problems help students determine their own strategies when solving problems, just as they would when they take a test.
