3/15/10	About Our Next Exam.  The exam will be on Thursday, 3/25, as scheduled.  I will continue discussing new material through next Monday, as detailed in our revised schedule.  We should get through section 4.5 by that time, and that is how far the exam will go.  To help students prepare I would like to hold a review sesion, either Tuesday (anytime), Wednesday (late afternoon or evening), or possibly early Thursday morning.  Please think about your preferences and availabilty so we can discuss this in class.  I will collect homework this Thursday as announced today in class: assignments from chapter 3 and section 4.1.  I will not collect any assignments next week, but you should work on them for discussion purposes.  Assignments that are not collected should be included in your portfolio.
3/15/10	Homework schedule:  Today I will discuss sections  4.3 and 4.4 up to page 249.  Homework from those sections (except 9 and 15 from 4.4) will be due for discussion on Thursday 3/18.  Any remaining assignments from section 4.2 and earlier will be due for collection on Thursday.  Please bring questions about those sections to class today.

2/4/10 (After Class)	In class today I distributed this handout concerning linear dependencies. I set up an online classroom within Blackboard.  If I am unable to make it to class Monday due to weather, I will hold the class online.  To access the online classroom, go to the main blackboard page for our course, and use the link on the left side of the page that says Online Classroom.  Before you can participate, you have to go through a set up process, which I suggest you do prior to Monday.  I didn't quite finish section 1.9 today.  Here is a brief overview of the missing material.
