An Analysis of Unit Assessments in Elementary-School Mathematics Textbooks
Nam Jinyoung 경인교육대학교 교육연구원 교육논총 21 Pages
경인교육대학교 교육연구원 교육논총 제 41권 특별호 8 133-153 (21 pages)
The 2015 revised elementary-school curriculum reduced the number of standardized tests in favor of course-centered assessments. As a consequence, textbook unit assessments have become more central and important. The present study analyzes unit assessments in elementary-school mathematics textbooks, developed in accordance with the 2015 revised curriculum, to determine whether they provide even coverage of mathematical content and competencies. The findings show that main lesson content is... -

This study was undertaken to examine the effect of ethanol on Na-dependent transport systems (glucose, phosphate, and dicarboxylate) in renal brush-border membrane vesicles (BBMV). Ethanol inhibited Na- dependent uptakes of glucose, phosphate, and succinate in a dose-dependent manner, but not the uptakes of Na-independent. The H/TEA antiport was reduced by 8% ethanol. Kinetic analysis showed that ethanol caused a decrease in Vmax of three transport systems, leaving...
