AMANDA, Ohio (AP) -- A substitute teacher's tool for silencing chatty kindergartners -- clothespins -- doesn't wash with school officials. Four boys said spring-type clothespins were placed over their upper or lower lips for talking too much in class, Amanda-Clearcreek Primary School principal Mike Johnsen wrote in a letter to parents this week. Ruth Ann Stoneburner, a retired school nurse who had worked as a substitute for several years, confirmed to Johnsen that she had used the clothespin discipline March 26, he said. Stoneburner will not work again in the Amanda-Clearcreek district and was being reported to the state education department, Superintendent J.B. Dick said Wednesday. Officials found out about the discipline after a parent complained. The students weren't hurt, but the punishment isn't condoned by the district, Dick said. Stoneburner could not be reached for comment.
