Features and Benefits

Emphasis on 21st Century Skills

NEW! Chemistry: A Molecular Approach, Fourth Edition helps students build 21st century skills by working through Data Interpretation and Analysis problems as well as Questions for Group Work. Check back to see our video of author Niva Tro explaining how he uses these features before, during, and after class.

Data Interpretation and Analysis Problems

The first of these 21st century skills is the ability to analyze and interpret data. Today’s students can access huge amounts of data all the time, but can they understand, interpret, and draw meaningful conclusions from it? A new category of questions called Data Interpretation and Analysis questions use real data from real life situations to ask students to analyze that data, providing practice in reading graphs, digesting tables, and making data-driven decisions. These are also assignable in MasteringChemistry.

Questions for Group Work

The second 21st century skill is the ability to work well in groups. To encourage this skill, Niva Tro created another category of questions called Questions for Group Work. These questions give students the opportunity to work with their peers in small groups in or out of the classroom. The goal is to foster collaborative learning and to give students the opportunity to work together as a team to solve problems.

Unique 2 and 3 Column Problem-Solving Strategy

Two- and three-column example formats help students break down the steps of each problem. The left column is what a professor would say when solving a problem. The right column is what a professor would write when solving a problem. Tro’s procedure maps not only work out a problem for students, but in many cases also apply the same methodology side-by-side to another problem similar in concept but slightly different.

Chapter Openers

Chapter Openers have been updated to highlight the relevance of chemistry and specifically, the chapter’s content, to students’ everyday lives, future careers, and world. New topics include the origin of the confirmation of the particulate nature of matter, how chemistry allowed Felix Baumgartner to take his record-breaking skydive, how milk of magnesia works, and how and why antifreeze is poisonous. These chapter openers keep the book fresh, relevant, and exciting.

New! Solids and Modern Materials Chapter covers current topics in this specialized field of chemistry. An advisory board of Material Chemists consulted with Tro to provide professional insight into chapter discussions.

New! Instructor Resources are organized according to their suggested use before, during, and after class.

New! The treatment of entropy has been updated to include calculations on the changes in entropy associated with changes in physical state.

High Quality Art helps students see the connection between the world seen with the naked eye and through the microscope. Multi-level images include–macroscopic, molecular, and symbolic representations.

Conceptual Connections appear throughout the text and ask students to think about concepts and solve problems without doing any math. Conceptual Connections are strategically placed to help students check their understanding of the most complex concepts and incorporated into Learning Catalytics for ease of assignability.
