This software is designed for the deaf and hard-of-hearing. Each volume teaches a different language skill, utilizing matching games and pop quizzes. Mainstream students can use the program also. Windmill Works specializes in software for the hearing impaired and offers other mainstream products such as trivia, e-books and a card game. President Billie Pagliolo holds a degree in deaf education and her husband, Michael Olmon, is a software engineer. Because existing programs weren’t always appropriate for Pagliolo’s special-needs students, she used her knowledge of syntactical structures to help them learn specific linguistic rules. “There isn’t a lot out there for deaf and hard-of-hearing students,” Pagliolo explained to TDmonthly.
