Math 2C03

FYI, the practice pb set #5 is available on webassign, and I have posted a copy of all assignments and practice pbs on the website.

I will be looking at my e-mail and at the team’s group chat during the test starting today at 5:30pm. Good luck!

By 5:30pm on Monday Feb 8th, you will receive an email from Crowdmark with a link to the test. Once you click on the button “Start the assessment now” you will have until 6:45pm in which to do the 4 problems (50 minutes for the test), scan them to PDF, and upload them to Crowdmark (25 minutes.) (SAS students excepted.) There should be 4 pdf files, one per question and they should be uploaded at the appropriate place, otherwise we cannot grade them. Late submissions will be penalized per minute past the deadline. As it takes time to create each pdf and upload your solutions, you should keep the timeline as above.

Test #1, will be on Monday February 8th, 5:30-6:20 (during normal class time,) plus extra time (25 min) for uploading your answers. The test covers all lecture material from the beginning through Monday’s class Feb 1st, so up to n-th order constant coefficient linear homogeneous ODE’s (but not including it), as well as the content of all homeworks, practice, examples in class and in tutorials. (See the “plan” for the topics.)

We will be using Crowdmark for the Tests. You will receive shortly an e-mail with a Mock assignment, so that you practice using Crowdmark. The idea is for you to log in to Crowdmark, create a password, and to go through the process of seeing what an evaluation looks like and how you are to submit your solutions. In particular, you will need to use a good scan app to upload: a phone picture is not good enough as it is too difficult to read. Here is some info about Crowdmark.

Once you have created your account, you will be able to see the Mock assignment. You can do this Mock assignment anytime until 11pm on Saturday, but once you start and look at it, you will have 30 min to submit your answers. Again this is a Mock assignment, coming from the practice problems, so it is NOT graded. This is for you to practice using Crowdmark before the 50 min Test on Monday February 8th at 5:30pm.

Calibration Exercise. Kritik requires a short Calibration exercise once in the term. Here’s how it works: each student will review the same three submissions, randomly chosen from Assignment #1, and give stars just as you would in the Evaluate phase. No written comments, and no Feedback stage. The idea is to set the baseline for how you are interpreting the Rubric, so that Kritik can better score you on your Evaluate steps throughout the term. As you’ve just gone through these problems, and there is no writing to do, I expect it will only take you 10-15 minutes to do the Calibration. It is due on Tuesday Feb 9th at 11:00pm. There will be a bonus for participation in this exercise.

The webassign assignment #3 has been posted on Friday. I will post the pdf files of all the assignments and practice problems under the practice problem page, for people who did not purchase webassign.

From the McMaster Student Union:

-“it takes less than 30 seconds to nominate someone who has had such a positive effect on their lives!” This term’s Teaching Awards nomination period is open from Monday February 1st, 2021 until Saturday February 13th, 2021 at 11:59PM EST. Students are welcome to nominate any and all of their current instructors from this semester (Winter 2021). 

Your TA is Pritpal Matharu: Survey link to nominate your TA: https://bit.ly/3iwoTBi

“For more information, please refer to our website (msumcmaster.ca/tac) or please feel free to reach out to us for any questions, comments, or concerns. “

Remember when doing the evaluation that there may be many approaches to a mathematical question, and part C in the Kritik assignment #1 is an example of that. Another solution to that part is to note that both y(x)= 1 + x^4 and y(x)=1-x^4 are solutions to the initial value problem (again this is due to non-uniqueness!)

Following the last poll, my office hour will be on Fridays 10:30-11:20, via Teams.
