Determine the types of tasks students will be assigned. Tasks can be an online quiz with multiple-choice questions or an open discussion requiring active participation or the online submission of a document or spreadsheet the student has prepared. Make students aware that a permanent record of their contributions -- in discussion or written form -- is always available to the evaluator. Ensure they realize how this can work both for and against them during assessment of performance. Specify the methods and criteria that will be used in the evaluation so that students know what is expected of them.
Evaluate content of written work submitted by students. Check the extent of research that has gone into preparation of a written assignment by observing the references used. Assess the student's ability to grasp fundamental concepts, interpret data and arrive at definite analyses of the topic provided to him. Allot higher grades to students who show evidence of critical thinking skills. Rank students on their ability to take a coherent stand on issues.
Assess the expression used to convey the content. Look for correct grammar, spelling and level of vocabulary. Check if sentence construction is sufficiently refined to allow the flow of ideas in a logical, smooth manner without compromising on clarity. Give a higher grade to a student whose assignments show an ability to express complex ideas in language that is well structured. Have a separate set of less stringent guidelines for evaluating expression during online discussions that are informal.
Use postings to online discussions and bulletin board systems as a measure of assessing student participation. Check the number of times a particular student has posted or replied to these forums to determine his involvement. More importantly, pay attention to the quality and quantity of the contribution. Give higher grades to students who contribute frequently and promptly in a proactive manner, without seeking to dominate the discussion.
