Combination Skill (CMB)
INTRODUCTIONCombination Skill develops the ability to perform multiple skills consecutively and/or simultaneously, specifically focusing on transitioning between and sequentially performing skills from separate Aquatic Safety Competencies. It is characterized by demonstrating the following skills in order: recover, tread, swim on back, float, orient, swim on front, exit. Becoming proficient with the Combination Skill develops Combining Skills Competency, as well as Safe Entry Competency, Safe Exit Competency, Breath Control Competency, Stationary Surface Competency, Orientation Competency, Propulsion Competency, and Risk Competency.
Blending components of, or transitioning between, multiple physical skills, cognitive skills, and affective skills allows individuals to adapt to the circumstances of any given situation. This is critical for remaining safe in aquatic environments, which are innately dynamic. Proficiency with independent skills is not enough to ensure safety. For example, it is not uncommon for individuals to be able to maintain a position at the surface while propelling but are unable to transition to resting while floating or into a vertical position to waive and call for help. Combination Skill is an opportunity for students to develop proficiency linking multiple skills sequentially, and become more comfortable transitioning between independent physical skills they have previously practiced.
When first learning to combine skills the focus should be on transitioning between skills sequentially and on skill combinations that are known to blend well together. An example of a well known combination is the act of traveling and turning to navigate towards safety, which is so common that it is often overlooked as being a combination of propulsion and orientation skills. The act of combining skills is a skill in itself, and the emphasis when learning should be on performing the combination, rather than focusing on proficiency with the individual components. Because of this, it is important that individuals have a base level of proficiency with the individual skills before learning how to combine them.
As individuals become more comfortable performing multiple skills sequentially, the focus should shift towards blending components of skills and performing them simultaneously. Importantly, this includes not only the combination of multiple cognitive skills, multiple physical skills, and of multiple cognitive and physical skills at once, but also the incorporation of additional stressors; for example recalling knowledge, performing assessments, and planning ahead while performing strenuous physical skills. Emphasis should be placed on learning how different skills (or skill components) will interact, as well as learning when to combine skills, in order to provide greater efficiency or more specificity when accomplishing tasks.
The Combination Skill is defined as the following:
Component Sequence
Start from submerged position
Recover to surface
Tread for 10 seconds
Swim on back or on side for 5 yards to float location
Survival float for 10 seconds
Locate and change direction to orient toward exit location; change of direction may be performed before, during, or after the float
Swim on front for 5 yards to exit location
Perform Safe Exit
Breathing
Breathing controlled during each component
Knowledge Objective
Recommended Teaching Guidelines
Assessment Prompt
If you accidentally fall into the water, what are three skills you can use to get to safety? Why those three?
Acceptable Responses
Any combination of three skills is an acceptable answer. Encourage the ‘why those three’ portion of the answer to string together how the skills will be used. For example:
Underwater swim to the surface so you can breathe, tread to look around and find safety, then swim on your front to get to the ladder and climb out.
Students may provide answers in a shorter list format, in this case, ask them to explain why those three skills work together. For example:
Tread, swim, safe exit.
Tread to get air and look where you want to go. Swim to move to the wall. Safe exit so you can get out.
Test Course
This test uses an out-and-back course. Start at the exit location. Perform one bob. Tread for 10 seconds. Orient toward the float location. Swim on back or side for 5 yards to the float location. Stop and survival float for 10 seconds. Orient toward the exit location. Swim on front for 5 yards to the exit location and perform a Safe Exit.
Scoring
The following scoring rubric lists the gradients of key requirements and deficiencies that provide an overall description of different competence levels.
A single score of 1 - 4 is assigned based on the instructor’s judgment of the student’s performance.
✔
1
Exhibits any of the following:
✖ Needs assistance to recover to the surface
✖ Does not swim for 5 yards to the float or exit location
2
Performs all of the following:
✔ Recovers to the surface
✔ Swims for 5 yards to the float or exit location
Exhibits any of the following:
✖ Does not change direction toward the exit location
✖ Does not exit safely
OR Exhibits two or more of the following:
✖ Treads for less than 10 seconds
✖ Does not swim on back or side for 5 yards to the float location
✖ Floats for less than 10 seconds
✖ Needs verbal or visual assistance locating the exit
✖ Does not swim on front for 5 yards to the exit location
✖ Breathing is not controlled during each component
✖ Does not perform skills in specified order; instructor may provide verbal assistance reminding the student of the skill order
