Parents Shocked By Swimming Instruction Techniques reads the article title. The technique involved tying a child’s shoes and throwing him into the pool. This was to teach him how to float even in “dangerous conditions.”
Ethically, just where do you start? If the purpose of swimming instruction techniques is to teach the child to swim, an overwhelming fear of the water caused by your own actions might be a detriment. Secondly, it does not appear from the article that parents were aware of this aspect of training.
As a parent I think I would like to be aware if the class had taken a turn toward training my child what to do if a comic book villain ties his shoes together and throws him into water.
I ran an internet search to see if this practice was common but had no luck. It’s possible it happens elsewhere. But search terms like “tie shoes together” and “swimming instruction” just don’t seem to get any hits.
