The Martin-Gay developmental math program offers a variety of print and digital resources so instructors can build the ideal learning solution for their students.
Martin-Gay’s NEW Student Success program is motivated by Elayn’s firm belief that every student can succeed. This integrated learning system combines the textbook, MyMathLab, student and video organizers, and the video program, and is designed to help students gain the math and study skills needed for success in developmental math and beyond.
- The new Ready to Go MyMathLab®courses provide students with all the same great MyMathLab features, but make it easier for instructors to get started. Each course includes pre-assigned homework and quizzes to make creating a course even easier. The Martin-Gay course provides a stepped-out learning path for students that integrates the textbook, videos, and Video Organizer to help ensure that students are using all resources.
- All videos in the video program are presented by Elayn Martin-Gay to ensure 100% consistency with the text, and are available in both MyMathLab® and on the Interactive DVD Lecture Series. The following types of videos are available:
- A complete lecture for each section of the text highlights key examples and exercises. New “pop-ups” reinforce key terms, definitions, and concepts while Martin-Gay presents the material.
- Interactive Concept Checks measure students’ understanding of key concepts and common trouble spots. After the viewer selects an answer from several multiple choice options, Martin-Gay explains why the answer is correct or incorrect.
- The Chapter Test Prep Videos help students during their most teachable moment–when they are preparing for a test. This Martin-Gay innovation provides step-by-step solutions for the exercises found in each Chapter Test. Complete solutions on video for all exercises from the Practice Final Exam (located in Student Resources) help students prepare for the real thing. Overview segments review key problem-solving strategies.
- The NEW Student Success Tips Videos are 3- to 5-minute video segments designed to be a daily reminder to students to continue practicing and maintaining good organizational and study habits (see New-to-Edition section for more information).
- Two Organizer options let you choose the option that best suits your teaching style and format.
- The NEW Video Organizer is designed to help students take notes and work practice exercises while watching the Interactive lecture series (available in MyMathLab and on DVD).
- All content in the Video Organizer is presented in the same order as it is presented in the videos, making it easy for students to create a course notebook and build good study habits.
- The Organizer provides ample space for students to write down key definitions and rules.
- The Video Organizer is available in loose-leaf, notebook-ready format and is also available in MyMathLab.
- Includes an outline for use with the new Student Success Tip videos
- The Student Organizer is designed to help students develop the study habits they need to be successful.
- This Organizer guides students through the three main components of studying effectively–note-taking, practice, and homework–and helps them develop the habits that will enable them to succeed in future courses.
- The Student Organizer can be packaged with the text in loose-leaf, notebook-ready format and is also available in MyMathLab.
- It now includes an outline for use with the new Student Success Tip Videos
The textbook, available in print or digital format, is the keystone of the Martin-Gay program. Elayn Martin-Gay is known for her accessible writing style and for the depth of resources she provides for instructors and students in her texts.
- Detailed step-by-step examples provide guidance for students.
- Practice exercises are paired with each example to actively involve students in the learning process.
- Concept Checks throughout the text allow students to gauge their grasp of an idea as it is presented in the text. By stressing conceptual understanding at point-of-use, the Concept Checks help prevent misconceived notions for important topics.
- All exercise sets have been carefully updated with this revision. Several special types of exercises throughout the text give students the practice they need: new Vocabulary, Readiness and Video Checks; Guided Applications; Mixed Practice; Concept Extension; and more!
- Martin-Gay’s presentation of Study Skills ensures that students make the most of their valuable study time in order to help them succeed in this course. In-text study skills resources include Section 1.1, Tips for Success in Mathematics and the Student Resources section located in the back of the book.
- End-of-chapter material offers students a wealth of review- and retention-oriented material to reinforce the concepts presented in current and previous chapters.
New and Updated Features
- Student Success Tips Videos are 3- to -5 minute video segments designed to be a daily reminder to students to continue practicing and maintaining good organizational and study habits. They are organized in three categories and are available in MyMathLab and the Interactive Lecture Series. The categories are:
- Student Success Tips Videos that apply to any course in college in general, such as Time Management.
- Student Success Tips Videos that apply to any mathematics course. One example is based on understanding that mathematics is a course that requires homework to be completed in a timely fashion.
- 3. Section- or Content-specific Student Success Tips Videos to help students avoid common mistakes or to better understand concept that often prove challenging.
- Vocabulary, Readiness, and Video Check questions have been added to the start of every section’s exercise set:
- The Vocabulary exercises quickly check students’ understanding of the new vocabulary words.
- The Readiness exercises assess a students’ understanding of concepts that are necessary to continue with the exercise set.
- Video Check questions for the Martin-Gay Interactive Lecture videos are now provided for each learning objective. These exercises are all available in MyMathLab and are a great way to ensure students have viewed and understood the key concepts presented in the videos. Each exercise in MyMathLab links students directly to the video for viewing.
New Student and Instructor Resources
- The NEW Video Organizer is designed to help students take notes and work practice exercises while watching the Interactive lecture series (available in MyMathLab and on DVD).
- All content in the Video Organizer is presented in the same order as it is presented in the videos, making it easy for students to create a course notebook and build good study habits.
- The organizer provides ample space for students to write down key definitions and rules.
- The Video Organizer is available in loose-leaf, notebook-ready format and is also available in MyMathLab.
- Two MyMathLab course options are now available: a standard course and a Ready to Go course.
- Standard MyMathLab courses allow instructors to build their course their way, offering maximum flexibility and complete control over all aspects of assignment creation.
- The new Ready to Go courses provide students with all the same great MyMathLab features, but make it easier for instructors to get started. Each course includes pre-assigned homework and quizzes to make creating a course even easier.
- Both course options will feature the following items:
- All videos from the Martin-Gay Interactive Lecture Series.
- Student Organizer (PDF) with hyperlinks to all video.
- Pre-made (and pre-assigned in the Ready to Go course) section-level homework assignments.
- Pre-made (and pre-assigned in the Ready to Go course) Practice Final Exam.
