In scuba diving instruction, truly learning a skill goes beyond just performing it well during the course. Effective learning means that students can retain and use those skills long after the course has ended. The Kirkpatrick Model helps evaluate training effectiveness by focusing on long-term results, not just immediate reactions or knowledge retention after class. To maintain skills, it’s essential for divers to practice regularly, as skills fade without consistent reinforcement. Instructors also need to continually practice and refine their teaching methods for sustained effectiveness.
