If We Tear It Down, We Might Build You A New One: The Troublesome Use Of Eminent Domain And Urban Neighborhood Swimming Pools, Steven N. Waller Ph.D., James H. Bemiller

International Journal of Aquatic Research and Education

Public swimming pools are a vital part of America’s recreation and sport culture since the early 1900’s. Municipal swimming pools were initially built to provide recreation and hygiene to urban communities, regardless of race or class. However, a complex history of segregation, civil unrest, suburbanization, and funding challenges has resulted in a significant decline in public pools, depriving many communities of vital recreational spaces. In many communities, options for sustaining the operation of swimming pools have resulted in pool closures. Unfortunately, once swimming pools close, especially those in aging neighborhoods in central city areas, they are seldom resurrected. They quickly …

Teaching Swimming To Children With Disabilities: A Qualitative Analysis Of Swim Instructorstea, Stephanie S. Garcia-Hidalgo, Martin E. Block

International Journal of Aquatic Research and Education

When teaching children with disabilities, swim instructors need to be able to assess the unique strengths and needs of each child to determine modifications needed to instruction, equipment, and the setting and then be flexible enough to make changes in real-time to ensure success for the child. Unfortunately, many swim instructors only work seasonally and have the occasional child with a disability, and as a result are likely to have limited training and experiences with children with disabilities. The purpose of this pilot qualitative study is to examine backgrounds, training, and experiences of six swim instructors who work with children …

Promising Practices For Increasing The Number Of Equity-Owed Lifeguards In Canada And The United States Of America, Sofia Pantano, Audrey R. Giles

International Journal of Aquatic Research and Education

Currently a shortage of lifeguards exists in Canada and the United States (US) (Frommer, 2023; Santucci, 2024), and those who are working as lifeguards often do not reflect the diversity of the communities they serve (Martinez, 2020). Increasing the number of lifeguards from equity-owed groups is a potential way of increasing the lifeguard workforce and decreasing the shortage of workers in these important roles, as well as a moral imperative. In this paper I explore challenges to and promising practices aimed at increasing the representation of members equity-owed groups in lifeguarding. I begin with an overview of lifeguarding in Canada …
