The authors of this article, all of whom have been a part of this effort to assess argumentation in literacy-rich science curriculum, have struggled with our attempts to build 3 argument-related assessments—understanding, critiquing, and constructing arguments about scientific phenomena in both oral and written modes. Loosely affiliated with the Seeds of Science/Roots of Reading Project at Lawrence Hall of Science, this effort focused on creating a suite of assessments as models for how middle school science teachers might create their own school-based, curriculum-embedded assessments of science. After reviewing the broad scope and insights derived from a 10-year history of assessments that operate at the intersection of science and literacy, we zoom in on 3 vexing but informative challenges they encountered—and addressed (if not resolved)—as they tried to assess the comprehension, critique, and construction of oral and written arguments. 相似文献

Flavonoids extracted from the leaves of Indian holy basil, Ocimum sanctum showed promising results as radioprotector in rodents.
Hence it was thought pertinent to analyze the antioxidants of erythrocytes in oral cancer patients who were concurrently treated
with radiation and ocimum flavonoids. Oral cancer patients consisted of 2 groups. Group A (n=17) received radiation alone
while Group B(n=17) received radiation and ocimum flavonoids(OF). Samples of heparinised blood were collected prior to treatment,
15 and 30 days respectively after treatment. Blood from normal healthy volunteers were taken as controls (n=25). Erythrocytes
were analyzed for the antioxidants viz. glutathione, glucose 6 phosphate dehydrogenase, glutathione peroxidase and superoxide
dismutase by the standard methods. Results of analysis indicated that erythrocytes from cancer patients (Group A and B) had
significantly high glutathione levels before as well as after treatment compared to controls. It was observed that Group B
which received OF showed a significant reduction in glutathione levels in comparison with Group A. All the other parameters
showed no statistical significant changes. Results of the study suggest that erythrocytes from cancer patients responded to
oxidative stress by elevating glutathione levels, while a decrease in glutathione levels observed in Group B, could be due
to the free radical scavenging effect of OF, sparing the glutathione. However OF did not seem to exert its effect on other
antioxidants of erythrocytes. 相似文献
