The notes for each class meeting will include the readings and other assigned background activities, such as exploring on-line resources or installing interactive software. Those notes will be posted long enough in advance to give you time to do the readings and other activities before class.
Assignments will be posted on the line corresponding to the date that they're due. Keep in mind that "assignments" here refers only to things that you're expected to turn in; the notes for each meeting include other assigned activities that you should do before class.
