AbstractThis paper presents the methodological lineaments that guided a research study designed to explore the language of a physics teacher through its discourse. It tries to analyse, in the teacher's discourse, the space assigned to the contents and procedures as basis to the understanding of the material environment and the conceptual organizations in a technology class. The records were made in technology classes, at High School N° 10 of the city of Tandil, by one of the authors who observed these classes during six months. The objective here is to provide the foundations of the methodological decisions that permitted to carry out the research in the ethnographic framework.

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.
