Lesson 1 • Emergency Action Plan Development
Covers EAP components, role assignments, communication protocols, and drill scheduling. Ensures instructors can activate and execute a coordinated emergency response.
Lesson 2 • Risk Identification and Hazard Control
Teaches systematic hazard identification, risk rating, and control hierarchy for aquatic facilities. Establishes the proactive safety mindset required before any lesson begins.
Lesson 3 • CPR, AED, and First Aid Integration
Reviews CPR and AED protocols and their integration into aquatic emergency response. Reinforces certification requirements instructors must maintain throughout their careers.
Lesson 4 • Aquatic Rescue Techniques for Instructors
Introduces reaching, throwing, and wading rescues appropriate for instructor-level response. Distinguishes instructor rescue responsibilities from lifeguard duties.
Lesson 5 • Incident Documentation and Reporting
Covers incident report writing, near-miss documentation, and post-incident review processes. Builds the administrative skills needed to fulfill legal and organizational obligations.
Chapter 5HideHide detailsSee detailsStroke Mechanics and Skill Progressions
Stroke Mechanics and Skill Progressions
Lesson 1 • Breaststroke Technique and Progression
Analyzes the simultaneous pull, kick, and glide cycle unique to breaststroke. Addresses the most technically complex stroke for beginner swimmers.
Lesson 2 • Backstroke Technique and Progression
Covers supine body position, alternating arm recovery, and kick coordination. Builds on freestyle body position concepts introduced in the previous section.
Lesson 3 • Survival and Elementary Strokes
Covers sidestroke, elementary backstroke, and treading water as survival skills. Ensures instructors can teach life-saving movement patterns beyond competitive strokes.
Lesson 4 • Freestyle Technique and Progression
Breaks freestyle into body position, kick, pull, and breathing components with drill sequences. Establishes the foundational stroke taught first in most learn-to-swim programs.
Lesson 5 • Butterfly Technique and Progression
Teaches the dolphin kick, simultaneous arm pull, and undulation rhythm of butterfly. Presented last due to its high coordination and strength demands.
