Generally I use objective evaluations to assess a student's knowledge of terminology, basic concepts, calculations. I use subjective evaluations to determine if the student understand the material well enough to effectively apply it in a case. For example, I teach courses in financial accounting, where the learning objective is for the student to be able to read and interpret a corporate annual report. The subjective assessment entails them selecting an annual report from a publicly traded company and, using all the ratios and comparator tools we discussed over the quarter, determine whether the company is financially stable, decline or growing, by interpreting the data they have gathered. It is effective in determining if a student really understanding the material. My issue with objective assessments is that some students are simply 'good test takers' and memorize well. It is the objective assessment that enables me to determine if they really understand the material.
