• Mark Clark

  Mark Clark graduated from California State University, Long Beach, and holds bachelor's and master's degrees in Mathematics. A full-time associate professor at Palomar College, since 1996, Mark is committed to teaching using applications and technology to help students understand mathematics in context and communicate results clearly. Intermediate algebra is one of his favorite courses to teach and he continues to teach several sections of this course each year. He is co-author of BEGINNING ALGEBRA: CONNECTING CONCEPTS THROUGH APPLICATIONS, INTERMEDIATE ALGEBRA: CONNECTING CONCEPTS THROUGH APPLICATIONS, and BEGINNING AND INTERMEDIATE ALGEBRA: CONNECTING CONCEPTS THROUGH APPLICATIONS published by Cengage. Mark shares his passion for using applications to teach mathematical concepts by delivering workshops and talks to other instructors at local and national conferences.

• 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.

• 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.

• APPROPRIATE USE OF GRAPHING TECHNOLOGY: Graphing calculators are used in this text to help students understand mathematical concepts and to work with real-world data. Graphing calculators are used to create scatterplots of real data and to verify reasoning related to data models. Linear, quadratic, and exponential models are created by hand, using an eyeball best-fit approach and algebraic techniques. The calculator is also used to check solutions both graphically and numerically and to do some numerical calculations. Students, however, are also required to solve problems, graph, and do other algebraic skills by hand.

• INCREASED EMPHASIS on identifying equation and function types within solving, graphing, and modeling problems. This helps students review previous material and connect it to the current topics.

• EXERCISE SETS include a balance of both applications and skill-based problems developed with a clear level of progression in terms of difficulty level. The exercise sets begin with vocabulary short-answer exercises. Most exercise sets begin with a few warm-up problems before focusing on applications. Exercise sets typically end with additional skill practice to help students master the concepts when needed. A balance of graphical, numerical, and algebraic skill problems is included throughout the book to help students see mathematics from several different views.

• FOUR TOOLKITS are included with this edition: the Equation Solving Toolkit, Factoring Toolkit, Expression Simplifying Toolkit, and Modeling Toolkit. Integrated throughout the text with visual icons, just-in-time help connects students to the solving techniques and tools used for different problem types. Each Toolkit emphasizes how these fundamental equations are used throughout the course.

• CHAPTER PROJECTS enhance critical thinking, and can be assigned either individually or as group work. Instructors can choose which projects best suit the focus of their class and allow students to demonstrate their mathematical reasoning. Some of these projects include online research or activities that students must perform to analyze data and make conclusions.

• CRITICAL THINKING FEATURE: Concept Investigations. These directed-discovery activities are ideal as group work during class, incorporated as part of a lecture, or as individual assignments to investigate concepts further. Inserted at key points within the chapter, each Concept Investigation supports student explorations of patterns and relationships represented by graphical and algebraic functions.

The exercise sets begin with vocabulary short-answer exercises. Most exercise sets continue with a few warm-up problems before focusing on applications. Exercise sets typically end with additional skill practice to help students master the concepts when needed. A balance of graphical, numerical, and algebraic skill problems is included throughout the book to help students see mathematics from several different views. End-of-book answers are written in full sentences to underscore the emphasis on student communication skills.
