Elluminate Chat Room Recordings
Use this link to go to the chat room list. Click the Recordings tab, then
use the calendar to navigate to the date for which you want to access a
recording. Find the room in the list and click on it. The recording
of that session will be played back for you. You can pause, rewind, and
fast forward while watching the recorded session.
Grade Estimating Spreadsheet
Use this link to download a Microsoft Excel spreadsheet that you can use to keep
a record of your scores and see what class average they give. You can even
play "what if" by entering scores you hope to earn on upcoming assignments to
see what average they will produce. This should answer that ageold
question, "What do I need to make on the final to get a (insert desired letter
grade here) in the course?".
