This model was used to assess water environment and obtain sea water quality categories of offshore area in Bohai Bay through calculating. The calculations shown that pollution index in river＇s wet season was higher than that in dry season from 2004 to 2007, and the pollution was particularly serious in 2005 and 2006, but a little better in 2007. The assessed results of cases shown that the model was reasonable in design and higher in generalization, meanwhile, it was common, objective and practical to sea water quality assessment.展开更多

That is, instead of creating an extra assessment outside the normal activities of the course, this paper examines an assessment that is part of the course. Additionally, not only is the course embedded assessment part of the course, it measures 100% of assessments employed in the course, instead of only a sample of the assessments. This paper presents background information regarding the utilization of a course embedded assessment, including The Association to Advance Collegiate Schools of Business International [AACSB] requirements for fulfilling assessment of learning outcomes. Discussion of course embedded assessments takes place. The dialogue then illustrates an approach that can be used for the data organization and analysis stages of assessment. It is hoped that the use of such an approach may save instructors time and effort in their assessment endeavors, while providing a superior quality assessment encompassing the entire course instead of merely a sample. This occurs by transferring the objective nature of the assessments into a computerized format.展开更多
