ANSWERS: TO CHECK YOUR UNDERSTANDING.
ANSWERS: TO ODD-NUMBERED PROBLEMS.
This new feature is located at the end of every chapter and replaces the Conceptual Questions. It consists primarily of multiple-choice questions that deal with important concepts. Some problems are also included that are designed to avoid mathematical complexity in order to probe basic conceptual understanding. All of the questions and problems are available for assignment via WileyPLUS. These algorithmically generated questions provide extensive feedback for both right and wrong answers.
MODIFIED CONCEPTUAL EXAMPLES
Conceptual examples appear in every chapter. They are intended as explicit models of how to use physics principles to analyze a situation described in a problem before attempting to solve the problem numerically. The Focus-on-Concepts questions provide the homework counterpart to the conceptual examples.
EXPANDED CHECK YOUR UNDERSTANDING
This feature appears at the ends of selected sections in every chapter and consists of questions in either a multiple-choice or a free-response format. The questions (answers are in the back of the book) are designed to enable students to see if they have understood the concepts discussed in the section. The collection of questions has been substantially increased relative to that present in the seventh edition, and the scope of the questions has been expanded considerably. Teachers who use a classroom response system will also find the questions useful to use as clicker-questions.
EXPANDED AND MODIFIED GOTM PROBLEMS
Some of the homework problems found in the collection at the end of each chapter are marked with a special GOTM icon. All of these problems are available for assignment via WileyPLUS. There are 332 GOTM problems, an increase of about 40% relative to those present in the seventh edition. In addition and new to the eighth edition, each of these problems in WileyPLUS now includes a guided tutorial option that instructors can make available for student-access with or without penalty.
QUESTION POOLS AVAILABLE IN WileyPLUS
Pools are groups of questions on a particular concept. When assigned, each student will receive one question from the pool in their assignment. Since most exams contain multiple choice conceptual questions, and students don't get an opportunity to practice these types of questions for homework, Question Pools in WileyPLUS will give students exam style practice. Question Pools were created by a member of the author team to ensure that all pool questions are at the same difficulty level and assess the same concept.
Mathskills MODULE ADDED TO WileyPLUS
Mathskills is a self-study module within WileyPLUS for students who need a quick review of the algebra and trigonometry topics that are prerequisite for introductory physics. This module is not meant to be a substitute for a comprehensive algebra-trigonometry course but rather a refresher for students who may need it. Each of the topics within the module has algorithmic questions that the instructor can assign (either graded or ungraded). There is a pre-built quiz that instructors can use as a diagnostic.
ENHANCEMENTS TO WileyPLUS PROBLEMS
Data Tables have been added to many problems. Like the tables found in the Analyzing-Multiple-Concept-Problems examples in the text, these tables provide an organized starting point from which students can begin the problem solving process.
A substantial number of Sample Examples have been added. These examples allow students to see worked out problems that are similar, but not identical, to those in their homework assignments.
Line drawings have been added to many problems that currently do not have them in the text. Students find it easier to begin the problem solving process when they can visualize the situation.
Students need a conceptual understanding of physics to build transferable problem-solving skills. Without a conceptual framework students just struggle through the course using pattern recognition and calculators to solve problems. Helping students develop a conceptual understanding of physics is one of the primary goals of Cutnell & Johnson. To this end the authors have developed a set of features (Check Your Understanding, Concepts & Calculations, Concepts at a Glance) whose popularity among students and instructors has made their text the market leader for the past 15 years. This feature set continues to be enhanced with new items such as the Analyzing-Multiple-Concept Problems (AMP). AMP problems are more sophisticated than “plug and chug” problems and involve two or more physics concepts. By using a highly visual layout they teach the student to first identify the physics concepts, then associate the appropriate mathematical equations, and finally to work out an algebraic solution.
Showing students the relevance of physics to their lives is another goal of the Cutnell & Johnson text. There is extensive support for premed and biomedical students taking this course such as: biomedical applications in the text and end of chapter problems marked with a caduceus, practice MCAT exams, and a supplemental book of biomedical introductory physics. There are also many other diverse applications throughout the text.
Working high quality problem sets is one of the best ways for students to learn physics. However, to benefit from working problems students need immediate feedback and varying levels of assistance. WileyPLUS provides the support instructors need to efficiently and effectively manage their classroom and improve student performance. Extensive feedback in the form of hints and suggestions are provided when incorrect answers are selected. Guided-Online problems are multi-step tutorial problems that are intended to provide the structure students need to incorporate concept identification into their problem-solving methodology.
