Introduction  #

The Retrieve Underwater Object skill develops Breath Control CompetencyBreath Control CompetencyBreath Control Competency is the knowledge, skill, and experience necessary to breathe effectively in a controlled manner without using excessive energy, interfering with other movements, or compromising body position while in the water. Physical abilities associated with this competency include the physical exchange of air and keeping the body in a position at the surface so that the exchange of air can occur. Cognitive abilities include determining when to breathe and when to hold the breath. Affective abilities include responding to stimuli and situations in a calm manner with the face both above and below the surface of the water. and Underwater CompetencyUnderwater CompetencyUnderwater Competency is the knowledge, skill, and experience necessary to submerge and control buoyancy to travel and negotiate hazards underwater. Physical abilities associated with this competency include being able to use the limbs to propel, to control and hold the breath, and to control and change body position and direction. Cognitive abilities include understanding position and orientation in three-dimensional space, to understand the relationship between breathing and buoyancy, to monitor and compare one’s current position to surrounding objects, and to plan navigation paths. Performing tasks underwater also requires being able to cope with depth, pressure, and reduced visibility. as its primary competencies. This skill teaches students to be comfortable with depth and pressure underwater.

Assessment  #

Test course  #

This test uses a stationary position course. Place the object on the pool bottom within reach of where the student will submerge. This assessment is not intended to test the student’s ability to swim or travel underwater; it is intended to test their ability to submerge, locate, and resurface. Therefore, the object may be suspended or held by the instructor above the pool bottom if the pool depth is more than 3 feet.

Scoring  #

The following scoring rubricScoring rubricA guide that includes rating scales and descriptions of one or more criteria used to evaluate the performance of a skill. lists the gradients of key requirements and deficiencies that provide an overall description of different competence levels. A single score is assigned based on the instructor’s judgment of the student’s performance.
