      • Identifying young gifted children

        Hoctor, Marge University of Southern California 2013 해외박사(DDOD)

        RANK : 247343

        Although there is a Federal definition of gifted and talented students, there are few state policies regarding identification of and services for students in kindergarten, first, and second grade. Most school districts do not begin their gifted programs until the third or fourth grade. Consequently, identification and implementation of appropriate differentiation of the curriculum is the responsibility of the primary classroom teacher. Since the role of the primary teacher is key, it is important to determine these teachers' attitudes, beliefs, and knowledge related to gifted education. The purpose of this study was to determine primary teachers' perspectives related to gifted education in the primary grades. The findings of the survey distributed to kindergarten, first, and second grade teachers provide quantitative and qualitative data related to the teachers' perceptions of the inhibitors and facilitators of identifying and serving gifted primary-aged students. Data were analyzed in accordance with the three categories that Clark and Estes (2008) define as reasons for a discrepancy between a goal and actual practice: knowledge, motivation, and organizational barriers. The data indicate that primary teachers are motivated to meet the needs of all of their students, including gifted students; however, most teachers surveyed did not have adequate knowledge of the characteristics of gifted students, or how to meet their needs in the classroom. In addition, primary teachers are often excluded from meetings and professional development opportunities related to gifted programs.

      • Regional landscape analysis and reserve design to conserve Florida's biodiversity

        The design and management of reserve networks are driving forces in conservation biology and landscape ecology. Reserve design principles and methods are continually being developed and applied worldwide. Designing functionally integrated reserve networks is now considered essential to conserve biodiversity, ecological functions, and evolutionary processes effectively. The state of Florida has been a leader in adopting systematic, landscape-based reserve design, and thus provides an excellent opportunity to explore regional landscape assessments and reserve design strategies for effective protection of biodiversity. In this study, I develop and compare three such approaches: (1) Identify a connected statewide network of intact landscapes and landscape linkages called the Florida Ecological Network. (2) Identify important habitat blocks and connectivity options for the Florida black bear, <italic> Ursus americanus floridanus</italic>, which may serve as an umbrella species for many other biodiversity components. (3) Develop ecoregional plans for the Florida peninsula that integrate fine filter, coarse filter, and landscape approaches for designing reserve networks. The Florida Ecological Network incorporates 9.3 million ha of large, connected landscapes, over half of which lie within existing conservation lands and public domain waterways. Over 5 million ha were identified as potentially high quality black bear habitat, with an additional 680,000 ha identified as landscape linkages to facilitate connectivity. The Florida Peninsula Ecoregion site portfolio contains 3.4 million hectares (51% within public domain lands and water) and the Tropical Florida Ecoregion site portfolio contains 2 million hectares (89% in public domain lands and waters). Collectively, 85% of the bear habitat and landscape linkages were within the Florida Ecological Network, which also overlaps with 84% and 90% of the Florida Peninsula and Tropical Florida Ecoregions, respectively. The results suggest the following: (1) Even given Florida's rapid urbanization, opportunities remain to protect a statewide reserve network that could protect most biodiversity effectively. (2) Each approach I developed identifies some unique areas for protection not found in the other two analyses. (3) Collectively, the assessments address the primary steps of reserve design including representation analysis, focal species analysis, incorporation of special resource elements, and considerations for maintaining or restoring ecological and evolutionary processes.
