I do not teach online but I do use assessment tools in my classroom. I use online testing and the one concern that I always have is the site user-friendly. Can the student use the username and password that I have assigned them to access the test with ease? Another item that I look for -- can the program scramble the questions so students cannot look on another student's monitor and copy the answer. Most of the online assessments sites that I have used have the ability to rearrange the questions and the answers. For reference I give multiple choice questions for my comprehensive finals. I want the student to know what grade they received on their final immediately. To sum up my criteria for online assessment tools I look for a user friendly environment; the accessibility of the site -- does the student have to download additional software in order to use it; and is the tool the right tool for the activity that I will have the students doing.
