The effects of prompts-based argumentation scaffolds on peer-led interactive argumentation
(University of Missouri--Columbia, 2009)
significantly greater amount of socio-emotionally enhanced strategy use. With regard to argument behaviors, students in all three conditions made a considerable number of opposing arguments, which could be attributed to the task design of the study. More...
Methods for high-resolution soil-landscape modeling in midwest upland landscapes
(University of Missouri--Columbia, 2008)
. These methods were tested in the upland landscapes of northern Missouri. Sensors, especially DRS, successfully estimated profile clay and organic carbon. Peak functions were valuable for modeling profile clay content and covariates of clay. Coherent depth...
