In this project, researchers will develop a prototype of Science Quest, a tool to assess the science skills and understanding for students in grades 1 to 3. The prototype will deliver psychometrically validated assessment items in a game-like format. Educators will be able to assign and monitor completion of science assessments, view assessment results in real-time with reports at the individual a ...

Chlorinated hydrocarbons represent the most prevalent contaminants of groundwater in the country. When released in the subsurface, they tend to persist below the water table, and it can take decades or centuries before slow-moving groundwater completely dissolves accumulations of chlorinated solvent product. Analytical methods currently available for monitoring these compounds require extensive ...

Heavy metal species mobilized and released into the environment by technological activities tend to persist indefinitely, circulating and eventually accumulating throughout the food chain, posing a serious threat to the environment, animals, and humans. Typical industrial metal-containing discharges can be considered as point-source emissions, which in turn offer the possibility of feasible remed ...

CSMP is an exciting K-6 math program, designated as an "exemplary educational program that works¿ by the U.S. Department of Education, which funded its development, evaluation, and dissemination. Its spiral, problem solving approach uses picture languages, abaci, and technically challenging games. Simple problems subtly introduce sophisticated concepts. While class and teacher-student intera ...

THIS PROPOSAL ADDRESSES THE DEVELOPMENT OF A MODEL PLAN FOR ANALYZING ARCHITECTURAL BARRIERS AS WELL AS RECOMMENDING GENERALIZED METHODS FOR OVERCOMING SUCH BARRIERS IN PUBLIC AND PRIVATE BUILDINGS. IT INCLUDES THE RESEARCH AND DEVELOPMENT OF A COMPUTER DATA SOFTWARE SYSTEM WHICH WILL ORGANIZE AND STORE THE LARGE AMOUNT OF INFORMATION NEEDED INTO A MANAGEABLE RETRIEVAL SYSTEM THAT WILL GUIDE THE U ...

CONTAMINATION OF GROUNDWATER BY TRICHLOROETHYLENE AND OTHER VOLATILE HALOGENATED SOLVENTS REPRESENTS A SERIOUS THREAT TO THE NATION'S DRINKING WATER. CURRENT TREATMENT TECHNIQUES FOR CONTROLLING SUCH CONTAMINATION ARE LIMITED TO AERATION, ADSORPTION, AND LINKING. A PROMISING ALTERNATIVE IS PHOTOCHEMICAL OXIDATION, BUT THIS PROCESS IS AS YET UNOPTIMIZED, POORLY UNDERSTOOD, AND LARGELY LIMITED. PHOT ...
