In early October, I sent a survey to our customers inquiring about the placement of answer keys. We’d had some requests to put the workbook answer key and the answer key for the chapter review questions in the books themselves, rather than in the instructor’s guides. Hundreds of people responded and the answer was overwhelmingly to leave them in the instructor’s guides. However, there were also some great suggestions for changes that can be easily incorporated. In future editions of our instructor’s guides, I’ll be creating one answer key for chapter reviews and one for workbook answers, separated by chapter, as handouts that instructors can distribute if they wish to do so. This seems to be something that will be useful. Thank you to everyone who responded!
