The LENA Research Foundation is a developer of advanced technology to accelerate language development of children 0-5 and for research and treatment of language delays and disorders. The nonprofit organization was created in 2009 through a donation of assets of Infoture Inc. by Terrance "Terry" and Judith "Judi" Paul, who are also majority owners of Renaissance Learning Inc. (RLI). The foundation’s principal product is the LENA System. The LENA System product line comprises LENA Pro, LENA Pro - Pilot Version, LENA Pro - Graduate Student Version, LENA Language and Autism Screen (LLAS), and the LENA Developmental Snapshot.〔http://www.lenafoundation.org/about.aspx〕 LENA Research Foundation customers include institutions of higher education, such as Brown University and Stanford University, and a number of schools for children who are deaf or hard of hearing ( (see list) ).〔http://www.lenafoundation.org/About/UniversityList.aspx〕 ==History== As the founder of Renaissance Learning, Terry Paul became familiar with the achievement gap caused by differences in home language environments. In 1998 he read ''Meaningful Differences in the Everyday Lives of Young American Children'' by Betty Hart, Ph.D., and Todd Risley, Ph.D. Based on data gathered through an intensive longitudinal study, ''Meaningful Differences'' revealed that the number of adult words spoken to children from birth to three predicted almost all of the variance in the children’s language ability and IQ at age three. Terry realized that with the help of advanced speech recognition technology he could streamline the data acquisition process and provide parents with a tool that was easy to use and could thoroughly chart a child’s natural language environment. He called it LENA (for “language environment analysis”). In 2004 Terry started Infoture, Inc. and hired a team of scientists, engineers, and scientific advisors to conduct the research and development work for the LENA System. Infoture launched a pilot version of the LENA System in February 2006. In February 2009 the Pauls donated the assets from Infoture and a gift of $2 million to create the LENA Research Foundation, a nonprofit organization.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「LENA Foundation」の詳細全文を読む スポンサード リンク
