Teacher's versions of science textbooks commonly include the answers to problems, as well as additional notes to assist the teacher in presenting the material to the class. These editions also sometimes prove useful for homeschooling parents and students looking for additional practice problems or to verify their understanding of material.
Using a teacher's edition of a science textbook may constitute academic dishonesty, depending on the instructor's or the school's policies, so it is important to check with the teacher before obtaining a copy of one. As long as referencing the teacher's version is not against the classroom rules, it can be a valuable study tool that allows students to check their answers to practice problems to make sure they understand the material correctly. Some teacher's versions also provide detailed explanations of the answers, which are useful when students are unsure of how to approach a particular problem.
