O objetivo desse trabalho é o de apresentar algumas técnicas de análise quantitativa, potencialmente úteis na abordagem de problemas de pesquisa em ensino de ciências com muitas variáveis, destacando os conceitos e os significados das mesmas. As técnicas apresentadas (Análise de Consistência Interna e Análise da Variância) são exemplificadas através do estudo das relações que quinze variáveis sócio-econômico-culturais tiveram com o desempenho em nove provas respondidas por 35463 candidatos ao Concurso Vestibular de 1999 da Universidade Federal do Rio Grande do Sul. O estudo mostrou que as quinze variáveis conjuntamente explicaram 34,2% da variância do desempenho dos candidatos, sendo 19,0% a explicação das variáveis de escolaridade independentemente das variáveis sócio-econômicas.Date

PALS - Performance Assessment Links in Science1999-01PALS is an on-line, standards-based, continually updated resource bank of science performance assessment tasks indexed via the National Science Education Standards (NSES) and various other standards frameworks. The tasks, collected from numerous sources, include student directions and response forms, administration procedures, scoring rubrics, examples of student work, and technical quality data calculated from field testing. On-line rater training packets have also been created for some tasks. PALS is supported by a grant from the Elementary, Secondary, and Informal Education (ESIE) Division (Grant #: ESI-9730651) of the National Science Foundation.

NASA Earth Observatory: Biomes (title provided or enhanced by cataloger)This National Aeronautics and Space Administration (NASA) website allows students to investigate biomes and then test their knowledge by completing missions. The site provides basic data about each biome such as temperature, precipitation, vegetation, location, description and links. Biomes discussed include coniferous forest, temperate deciduous forest, desert, grassland, rainforest, shrubland and tundra. The two missions (available at beginner and advanced levels) are designed to teach students about the relationship between temperature and precipitation and plants in biomes. A teacher resource guide provides details about goals, expected outcomes, extension ideas, and hands-on activities.
