Based on our research, we know that refresher lessons are important because children change so much both cognitively and physically during the first 0-5 years of life. It is important that their water survival skills grow with their bodies. Frequency depends on the child's age, growth rate, skill level and confidence level. The goal of refresher lessons is to help your child adjust his/her new body size and weight to his/her existing skill level. Your instructor will work with your child to help fine-tune his or her aquatic experience to assist with building efficiency, which will result in self-confidence. This is especially important if your child has not been able to practice any appropriate aquatic skill between seasons.

The reason for this is multifaceted. First, repetition and consistency are crucial elements of learning for young children. Research shows that short, more frequent lessons result in higher retention. Second, most children have fairly short attention spans and will not be able to focus on the task for longer and we want to take advantage of the best time for learning. A third reason is that, though the pool temperature is maintained at 78-88 degrees, the temperature is still lower than your child's body temperature. Lessons are work and therefore will also be losing body heat. Instructors check students regularly for temperature fatigue since this is an indicator of physical fatigue.

Children often fuss during the first few lessons because they are in a new environment and around new people. As your child becomes more confident in his/her ability in the water, the fussing will decrease. It is not unlike the first time you tried a new exercise class or were asked to perform a task at work that you’d never done before: the first time you try a new task it is always challenging, until you get the hang of it. It is the same for your young child. Your child is learning to perform a skill that he/she’s never done before.

ISR instructors teach infants to swim by honoring each child's individual strengths and experiences. They understand the fundamentals of the behavioral sciences, child development and of sensori-motor learning as it relates to the acquisition of aquatic survival skills; they use this education to guide each child through the sequence of learning to swim and float.
