All eight versions of the final exams, and the answers to the exams, are available on the course website under Classes > Exams. The practice exam, with answers on the last page, is also available there. The question booklets of students who took the final exam on Saturday, December 16, will be available in the Principles Center between first day of classes (Jan 18, 2018) and Feb 15, 2018, for students to pick up.
Please read this announcement carefully and check the data on BlackBoard MyGrades before you send out emails. If it is at all possible please avoid sending me or the TFs emails until after January 3, 1918. I do not plan to be in my BU Office until that date. All emails to me or to the TFs should contain “EC101” on the subject line.
Your EC101 course grade has been submitted. Your final exam scores, and all other course data (except clicker scores) are posted on BlackBoard MyGrades. I will send you an email if your clicker score was unsatisfactory. Because the Tuesday final exams were more difficult than usual, the score was adjusted upwards by 1.67 percentage points, the equivalent of one more correct answer.
Your course grade was computed mechanically. No subjective judgment was used, except possibly by the TFs in formulating your 5 point participation score. If I reduced your letter grade because of poor attendance (insufficient clicker response), you would have already received an email from me.
Course averages are very close together, and there is no gap that forms a good place to separate letter grades. Here is a sample of actual course averages in decreasing order that covers the boarder between B+ and A-.
90.9, 90.8, 90.8, 90.8, 90.7, 90.7, 90.6, 90.4, 90.4, 90.2, 90.2, 90.1, 90.1, 90.1, 90.0, 90.0, 89.9, 89.7, 89.5, 89.3, 89.3, 89.2, 89.1, 89.1, 89.1, 89.0
As you can see, I have no choice but to use a strict rule: I round the average to one decimal place, and those at or above the limiting average receive the higher letter grade, those below receive the lower letter grade. Also, I think it’s important that grades be a reasonably accurate reflection of a student’s accomplishments in the regular coursework, so I don’t grade on the basis of need, and I don’t allow student to get points for extra work.
After the new year, I will post all 8 versions of the Final Exam and the correct answers on the course website under Classes>Exams.
I cannot investigate the entire record of every disappointed student during the intersession. But any computational error brought to my attention will be corrected, and any incorrect course grade will be changed by early in the spring semester. If you believe your TF committed an error in formulating your discussion-section score, please write to your TF (not to me).
Please check your record on My Grades carefully and use the grading formula under Course Info>Examinations and Grades before you write to me about possible errors in grading. Exams and Grades includes an exact description of how letter-grades are determined. Keep in mind that unless there is an error, I will not change your grade under any circumstances.
Believe it or not, there are more important things in your life than your grade. So have a great holiday break and a good rest. –Michael
These are questions frequently asked by students in EC101 DD/EE. When students send me emails with questions about the course, I will update this post. –Michael
- Do I have to buy a clicker?
Yes. You are required to buy a Turning Technologies student-response device, often called a clicker. I recommend that you buy it at the BU Bookstore. The clicker comes with a 1-semester, 1-year or 5-year subscription–be careful not to lose the certificate. Go to Course Information > How to Buy a Student Response Device for more information. Be prepared for many steps :-( . I no longer allow students to use smartphone apps, because they often fail to connect to the internet during the lectures.
- I am unable to register or obtain a subscription (license) for my clicker. What should I do?
Call TurningTechnologies at 866-746-3015, 8:00am–9:00pm Boston time or go to their technical-support website.
- Where are the problem-set assignments?
All problem-set assignments will be posted on the course website. Go to Classes > Problem-Set Assignments on Friday evening of the week before they are due. The problems will be reviewed in your discussion sections on the week they are due.
- Do I have to finish assigned textbook readings in the Course Schedule by the date that’s given there?
No, the dates on the course schedule are only a suggestions. But try not to fall behind. Keep in mind that the exams (80 percent of the course grade) are focused on the lectures, and the textbook is to be used mainly as a reference and for the homework assignments and quizzes.
- Can I get a copy of the lecture slides?
No, I don’t distribute those. But you can download a pdf copy of the Lecture Outlines, which are similar to the slides. The outlines omit the pictures and some of the lecture details, but they leave you a place to add your own notes. To download the lecture outlines go to Classes > Lecture Outlines.
You can review the contents of a quiz, but only after the day and time the quiz is due. To review the questions, log into MyEconLab, and then click on Results in the menu on the left (do NOT click on Assignments). After that, you will see the word Review for each quiz in the list of quizzes. Click on Review.
