Abstract
When teachers integrate online discussions into courses, they are faced with the challenge of deciding how to evaluate the postings. This chapter discusses a study that used a discussion board rubric to evaluate online discussions. The study tested the reliability of the instrument (rubric) to assess the quality of the content of Web-based discourse. To obtain the rubric interrater reliability, researchers used the rubric to evaluate the discussion postings of preservice teachers’ enrolled in six different sections of an English language arts methods course. Six hundred sixty two (662) postings from 165 preservice teachers were analyzed using the rubric. The study utilized the scorings from six judges. When measured with Cronbach’s alpha intraclass coefficient, the findings indicated substantial agreement between judges in two of the four rubric criteria: evocative (.8742) and reference-resource (.8209). The other rubric criteria rumination (.7256) and storytelling (.5984) scored at the moderate and fair levels respectfully.
