Data for sections A01 and A05 now are complete and they have been
uploaded to BB. The letter grades have also been uploaded to BU Brain.
b.
I wish you all a wonderful summer break and all the best for your

Grades for sections A01 and A05 are expected to be finalized tomorrow,
Saturday, May 19.
An announcement will be made when this is done.
|

a.
Arielle Roth is still working on completing her grading for sections
A01 and A05.
You should see the grades for the final exam at this point in time.
Your letter grade will be computed once I know that her work is completed.
b.
All other sections: Be sure to check your letter grade in BU Brain and
compare it to BB.
I managed to enter two grades incorrectly into BU Brain,
even though I had another person watching for data entry errors.
It is possible that more persons are affected.

a.
Format of the final:
The final will be a full 120 minutes and many of the problems will be like
what you saw on the midterms: some multiple choices and fill in the blanks,
some free form answers, some lengthier computations.
Whats different: There will be material from the later chapters 25, 26, 28
where you are given computer output and you must figure out what to do with it.
b.
Except for the final and attendance, all your grades should now be on BB.
Check for attendance on Thursday evening, after 8:00 PM.
If you have any issues, email your TA with me in the cc and ask to meet with
her/him. Do so asap! (except for attendance)
c.
Be early: The finals are labeled with your name and you will lose points
if you are too lazy to look for your seat and take someone elses final!
You must approach your TA if you cannot find your seat!
d.
Bring your student IDs: We will make spot checks!
Index cards are bigger than for the midterms: 8 x 5 inches. Don't turn them
in with your final. You are not allowed to write with a pencil!
e.
Pack your calculator and spare batteries or a backup
the day before the final!
f.
How to practice: I have said this many times: Best you take the fully worked
examples of the text and try to solve them closed book.
Review the summaries.
|
| 5/8/2018 |
a.
Office hours for today, Tue May 8, are canceled.
b.
Finals prep: As I advised during Monday's review session, you should
try to do the fully worked in-chapter problems of the text closed book
and compare your solutions with those in the text.
c.
Finals review session by Casey Kapklein
on Thursday, May 10 from 3:30 to 6:30 pm in Lecture Hall 10.
No need to sign up beforehand. Come prepared with questions!

I will bring the Math department's free form SOOT forms to lecture today
and on Friday. They are anonymous, so please do not write your name on
them. I read those forms and I make adjustments to the way I teach based on
your comments, so I am grateful if you let me know what you like
and what you dislike about my course.
Please bring the forms back during the final exam.
I'll designate one or two spots where you can drop the forms
(you can leave them blank if you have nothing to say).

The deadline to apply for the makeup final has passed last Friday.
Those who have done so have received an email from me earlier today.
If you did apply but did not receive that email, be sure to notify
me AND YOUR TA immediately and show proof of your scheduling conflict
to your TA during this week's discussion section.
If you forgot about that deadline: Send an email to me AND YOUR TA
immediately and show proof of your scheduling conflict to your TA
during this week's discussion section.

Notes concerning the textbook:
Do you need the access code? I stated in the syllabus that it's
required, but I also stated that
all homework that will potentially be graded can be done without
a visit to the DVB website.
However, you may achieve a lower grade because you miss out
on the practice problems I post there. Moreover you won't be able
to use StatCrunch.
You spend so much money each semester that I think you
are "penny wise and pound foolish".
Note that Pearson made a special price for the loose leaf version
with MyStatLab access. Just buying that access code will cost you
about half the price of the entire package.

Homework 2 has been posted, together with optional MyStatlab
homework "MATH-148-CH-02".

b.
Syllabus and course material page now have information
about registering with the MyStatlab website (also called the
DVB website). Once you have access to MyStatlab you can
access homework "MATH-148-CH-01" (optional) on that site.
c.
Blackboard ("MyCourses") has not yet been set up for Math 148.
We only use Blackboard to post the grades you get on your exams,
quizzes and homeworks and to provide a PDF version of the syllabus.
in addition to the HTML version found on this website.
