- Chemistry: The Central Science incorporates a consistent problem solving process throughout so students always know where to go when problem solving.
- Analyze/Plan/Solve/Check helps students understand what they are being asked to solve, to plan how they will solve each problem, to work their way through the solution, and to check their answers. This 4 step problem solving methodology is introduced in chapter 3 (pg. 89) and implemented throughout the book.
- Dual-Column Problem-Solving Strategies in Selected Sample Exercises explain the thought process involved in each step of a mathematical calculation using a unique layout for clarity. It provides students a conceptual understanding of those calculations. (pg. 90)
- Strategies in Chemistry teach students ways to analyze information and organize thoughts, helping to improve problem-solving and critical-thinking abilities. (pg. 106, 143, 404)
- Sample Exercises incorporate molecular illustrations to help students visualize what is happening on a molecular level when they are asked to solve a quantitative problem. (Pg 85, 130)
- Visualizing Concepts exercises precede the end-of-chapter exercises and ask students to consider concepts through the use of models, graphs, and other visual materials. (pg. 108) These help students develop a conceptual understanding of the key ideas in the chapter. Additional conceptual exercises are found among the end-of-chapter exercises.
Practice and Review:
- End-of-Chapter Exercises are grouped by topic and presented in matched pairs, giving students multiple opportunities to test each concept.Additional Exercises follow the paired exercises and are not categorized, because many of these exercises draw on multiple concepts from within the chapter.
- Integrative Exercises, which are included among the exercises at the end of chapters 3-25, connect concepts for the current chapter with those from previous chapters. These help students gain a deeper understanding of how chemistry fits together and serve as an overall review of key concepts.
- Many chapters also contain a Sample Integrative Exercise to show how to analyze and solve problems that encompass more than one concept.
Outside of the Classroom:
- MasteringChemistry steps students through problem solving while promoting understanding of chemical concepts outside of the classroom.
- Backed by NSF funding, this online homework, assessment, and tutorial system helps students figure out where they are going wrong when problem solving by providing answer specific feedback. The program enables professors to compare their class performance against the national average on specific questions or topics. At a glance, professors can see class distribution of grades, time spent, most difficult problems, most difficult steps and even the most common answer.
- Answer specific feedback to students in the form of Socratic and declarative hints so students learn where they are going wrong.
- Gradebook with detailed diagnostics that enables professors to see both at-a-glance and in-depth perspectives of their student’s progress.
- Items (problems) show difficulty and duration which demonstrates educational effectiveness and facilitates in assignment creation.
