Effective scuba diving instruction requires clear learning objectives for students. These objectives should focus on observable changes in behavior, rather than vague terms like “understand” or “learn.” For example, instead of saying a student will “know about decompression theory,” a better objective is “by the end of this session, you will be able to list two factors affecting No Decompression Limits.” This specificity ensures that both instructors and students can evaluate learning success. Establishing proper learning goals helps create a more productive diving education experience.
