AbstractCurrent studies on didactical physics laboratory have been based in the use of the hypothetical-deductive method, proposing the development of the experimental activities as an investigation process, that reveals its popperian inspiration. In this work, starting from a discussion about different possibilities to understand the relationships between theory and experiment, we propose, based on Thomas Kuhn's ideas, complemented by the thought of van Fraassen, a new orientation for the Physics laboratory, conceiving it, not as a verification or falsification of hypotheses, but as an adaptation process between theory and experiment.

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.
