To assess student understanding of our vocabulary words, we wrote short vocabulary quizzes for each topic, ranging from 3 to 13 questions each. The database includes a total of 195 questions with multiple choice, true/false, matching, multiple answer, fill in the blank, and drop down menu question formats. Questions are identified by topic, number of points possible, and question type. The question database is currently available in two formats: MS Word files and Respondus archive files for upload to the CMS Blackboard. Student responses can be downloaded from Blackboard and the ePort package used to summarize overall performance on each topic and each question within the topic. Click on the vocabulary words below to view some example questions for Topics 06 and 19.
