(2)請簡要論述下列有關資賦優異教育之短文。It is commonly recognized that the development of the gifted and talented education (GATE) in Taiwan started in 1973, when the Ministry of Education launched experimental programs throughout Taiwan for academically talented elementary students. Generally speaking, the development of GATE could be divided into five stages: The dawning stage before 1973, the experimental stage (1973-1983), the promoting stage (1984-1994), the established stage (1995-2005), and the transformation stage (2006-present). Given these stages, educational practices of gifted and talented education, issues of pre- and in-service teacher education for GATE, and the current state of research in gifted education are thoroughly discussed. Finally, as a global vision of GATE in Taiwan, to develop the talent based on individual differences and enhance high-quality education, four prospects are proposed: (a) develop gifted and talented students with both smart brains and tender minds, (b) enhance quality of gifted and talented education, (c) replace the examination-oriented mind by adaptive education, and (d) take advantage of opportunities from the new system of 12-year national education. 資料來源：Wu, W.-T., & Kuo, Y.-L.
