Tutoring

Just a reminder: tutoring is available and if you ask the tutor for a verification slip, you can give it to me for participation credit.

I hear the tutors haven’t been too busy yet this semester, so now would be a good time to use the resource. All students can benefit from attending tutoring, even students who are already doing well in the course.

Tutoring 9am-5pm Atrium Learning Center AG-25

This week’s quiz will cover material from last week’s classes: sections 4.8, 7.2, 7.4, and 7.5.

Test #2 and Test #2 Review – OpenLab assignment

Test #2 will be held in class next Thursday, March 29. Check the schedule for the topics covered. The test will cover sessions 10-16 but you may need techniques from sessions 1-9.

Like last time, choose one question from Webwork, textbook homework, or the final exam review sheet to complete and share on the OpenLab. Don’t forget to add the category Test #2 Review before you publish your post. Let us know in the post title where the question is coming from. Posts are due by 10am on Thursday, March 29 (right before the test, though earlier is better).

Last time most of the solutions that people shared focused on only a few topics and the questions tended to be shorter and easier than the ones on the test. This time, try to make sure all the different topics are represented and try to include questions with longer or harder solutions.

This assignment will count toward your participation grade.

Test #1 solutions – OpenLab assignment

For your next OpenLab assignment, you will submit a post containing the full solution for one of the questions from test #1. Be sure to select the Test #1 Solutions category from the right-hand side of the screen before submitting your post. There were 4 different versions of the test. Some of the versions had questions in common. While it is okay if two people submit solutions for the same question, try to submit one that hasn’t been submitted yet so that eventually solutions for all test questions are online. Try to submit a solution for a question for which you did not receive full credit.

Everyone’s deadline is Tuesday, April 3 at 10am (during spring break). The first day to submit your post depends on your Test #1 grade.

  • If your Test #1 grade is below 60%, the first day for you to submit your post is today, Tuesday,  March 20.
  • If your Test #1 grade is between 60% and 80%, the first day for you to submit your post is Thursday,  March 22.
  • If your Test #1 grade is above 80%, the first day for you to submit your post is Tuesday,  March 27.

If you notice an error or have a question about someone else’s post, please comment on it.

This OpenLab assignment will count toward your participation grade.

Test #1 Review

Thanks to everyone who’s posted Test #1 Review questions and solutions. I haven’t taken a close look at all of them yet so you should read your classmates’ solutions carefully and post a comment if you have a question or notice an error.

I did notice that many of the questions involved solving radical equations. I’m glad to see these here, especially since they’re some of the longer solutions. I also noticed some of the other questions posted were shorter and easier than the questions you can expect to see on Thursday’s test.

Don’t forget to practice questions with longer solutions and from the other topics from sessions 1-9.

Also don’t forget that you can get help at tutoring. If you bring me a verification slip from the Atrium Learning Center, it will count toward your participation grade.
