Of the more than 400 studies presented at the 18th International Congress on Education of the Deaf, the 20 most incisive papers were selected, rewritten, and edited to construct the trenchant volume Issues Unresolved: New Perspectives on Language and Deaf Education. The resulting book provocatively challenges the invested reader in four critical areas of deaf education worldwide. Part 1, Communication: Signed and Spoken Languages, addresses matters that range from considering critical periods for language acquisition, researched by Susan D. Fischer, to assessing the impact of immigration policies on the ethnic composition of Australia's deaf community, intriguing work by Jan Branson and Don Miller. Part 2, Communication: Accessibility to Speech, continues the debate with works on the perception of speech by deaf and hard of hearing children, contributed by Arthur Boothroyd, and automatic speech recognition and its applications, delineated by Harry Levitt. Educational issues are brought to the forefront in Part 3 in such engrossing studies as Lea Lurie and Alex Kozulin's discourse on the application of an instrumental-enrichment cognitive intervention program with deaf immigrant children from Ethiopia. Stephen Powers offers another perspective in this section with his retrospective evaluation of a distance education training course for teachers of the deaf. Part 4, Psychological and Social Adjustment reviews progress in this area, with Anne de Klerk's exposition on the Rotterdam Deaf Awareness Program, and Corinne J. Lewkowitz and Lynn S. Liben's research on the development of deaf and hearing children's sex-role attitudes and self-endorsements. These and the many other contributions by renowned international scholars in the field make Issues Unresolved a compelling new standard for all involved in deaf education.
