Math 148 Announcements

5/30/2021   a. Your grades have been uploaded to your discussion Blackboards. You will notice that the columns
    QSum • QuizAdj • HwSum • HwAdj • TotSum • TotAdj • TotAdj+5
now contain data and that there are to new columns,
    TotAdj+5 • Grade.
I do not think I have to explain to you the meaning of the Grade column but you should understand how the others were used to determine your grade.
  •   QSum: Contains the sum of all 12 quizzes.
  •   QuizAdj: QSum minus the two lowest point quizzes.
  •   HwSum: Contains the sum of all five graded homework sets.
  •   HwAdj: HwSum minus the lowest point homework.
  •   TotSum: QSum + HwSum + sum of all four major exams.
  •   TotAdj: QuizAdj + HwAdj + sum of all four major exams. This figure contains the points that count according to the syllabus for your letter grade but instead there is ...
  •   TotAdj+5: Five points that were added to TotAdj for each one of you. This means that it shows a value of say, 848 points, then you are not two points but seven ponts away from an A-.
      Accordingly I will ignore any pleas to give you a better grade since you are "so close".
  •   Your letter grade has been computed from the TotAdj+5 points according to the grading scale (no more tentative now) displayed in the syllabus.
b. The last thing that remains for me is to say goodbye to you. I wish you all a wonderful summer break,
that worrying about masks and six feet distancing will be a thing of the past when you return to school this fall, and that you will be successful in your further studies and beyond.
Best wishes for the future -- Michael Fochler --
5/20/2021   a. I have updated my Zoom link for tomorrow, Friday May 21 @8:00, the start time of the final exam. I will only clarify issues that concern the problems themselves. Everything else your TA will help you with.
b. There are no images to upload: all free form problems are "ESSAY" type questions and you must type the responses.
This means that you should save frequently so that you do not lose more than a few minutes of work in case there are internet or Blackboard issues. The time will be set for 122 minutes, so that is a 2 minute bonus for you.
Good luck!
5/17/2021   a. I just verified that I did not receive any request for a make-up final due to scheduling conflicts. If you did send such a request on time then you must forward the original email to both me and your TA. The deadline has passed more than a week ago (May 7) so there will be no makeup exam except for illness. That makeup will be at a time mutually agreed upon with your TA, but it will begin no later than Monday, May 24, 11:00 AM.
b. Remember that there will be another UTS review session this Thursday, May 20 from 3:00pm-5:00pm.
5/12/2021   a. I already announced this one by email: There is a UTS review session for Math 148 today, 3:00-4:00.
If you have not signed up for it yet then you must email directly Birgit Nicolaisen at birgit@binghamton.edu.
b. I will also have a Zoom session active during the time of the final exam but only to clarify issues concerning the problems such as unclear wording or seemingly contradictory information.
If you have any technology issues such as Blackboard or internet connectivity related problems then your TA will take care of that.
c. Today's lecture recording has been posted.
5/12/2021   a. Your TA will have a Zoom session active during the time of the final exam. Using the chat feature or speaking up will be your fastest response if you have questions.
You are not required to attend via Zoom per se but you must raise an issue first by chat or speaking up in Zoom if you expect a response.
b. Lecture and discussion recordings are up to date.
5/12/2021   a. Two finals review sessions this coming Friday and Monday
b. Lecture recordings are up to date.

5/5/2021   IMPORTANT for today's midterm:
a. If you claim that internet issues caused you to lose time then you must see to it that you have evidence in form of a screenshot.
Be sure that that screenshot does show the computer clock!
A lecture in Darwinism: Turn on the time stamps on your cell phone so that if you take pictures of your handwritten work you have that as evidence.
b. If you do encouter a problem then contact your TA IMMEDIATELY! You can put me in the cc but s/he is the one to take care of you. By all means, put me in the cc.
c. Good luck!
5/2/2021   You will have 70 minutes to complete midterm #3. The reason: There will be five problems for which you need to take screen shots.
Be mindful that your TA will not grade what s/he cannot read. I will not say more than that.

4/22/2021   a. Discussion recordings are up to date.
b. Here is a clarification about grading issues in case your TA was not the one who graded the problem at issue. Before I become involved in any such matter you will always go through your TA. S/he will then consult with the TA who actually graded the exam if necessary. Only if that does not resolve the problem will I make a final decision.
4/18/2021   HW 10 has been posted. Due next Thursday by email to your TA. There are only three problems for ch.22 since I still have to cover a substantial part on Monday and you may decide to wait until then to work on them.

3/15/2021   Monday's lecture recording has been posted
3/13/2021   a. HW 5 has been published. Start with the chapter 11 problems since you may not know enough to do the ch.12 problems before I am finished with Monday's lecture. Due as usual on Thursday.
b. If you ran out of time when uploading your work to BB then you have to show evidence in form of a time stamp to get some points back.
Here are some things you can experiment with in preparation for the upcoming exams, not only for this course.
  • To cut down on transfer time: Do not choose the highes quality setting. Writing a jpg (jpeg) file of size 400K should give you more than sufficient quality. It's more important that your pen is sufficiently dark and thick.
  • To avoid email phone to PC altogether: If you have an Android device you can try out Droid Transfer or (in Windows) just use your native file explorer to transfer your pics via USB to your laptop and then upload them from there to BB.
  • If the problem is with BB as so many of you have claimed then email the screenshots to your TA (not to me) with a clear indication in the email subject similar to
    "BB trouble: pics for problems #__, #__, ... attached". But you have to do so BEFORE THE TIME HAS PASSED or points will be taken off

3/11/2021   a. You all should have been notified by your TA about the exact time when they will release the exam in their discussion Blackboard.
b. All discussion recordings for this week have been posted.
9/22/2020   Midterm 1:   •   Given online, in your discussion Blackboard, on Fri, 3/12, at 12:00 PM.
  •   Duration: 60 minutes + 5 extra minutes for uploading.   •   Procedure: Just like a 60 minutes long quiz.
  •   Consult the syllabus on what is considered cheating and what will happen to you if we catch you.
  •   Scope: ch.1 - ch.8 and ch.10
a. Be sure to follow the instructions. Here is an example of what you might see:
>>choose the one closest to your answer: one of A = 0, B = 1.25, C = 2.5, D = 5 , E = 25, F = 50, G =75, H = 95, I = 97.5, J = 98.75, K =100<<
This means the following: If you computed an answer of 2.486 then the closest selection would be 2.5, and that one comes with the letter C.
Be sure to enter the letter C, NOT the number 2.5 or the number 2.486! The computer will not be able to figure out that you had the right thing in mind!
b. There are no practice exams, but here is how you prepare:
  • Consult the Finals prep sheet (link on course materials page) to see what you may safely ignore for the exam.
  • Read the summary and the glossary of terms at the end of each chapter.
  • Focus on doing problems for which you know the solution. Ideal are the fully worked examples in the chapters of the text.
  • Review your quizzes.
c. The Zoom recording of today's lecture is available.
3/7/2021   a. Your TAs will release a test called Sample-File-Response-Problem in their discussion Blackboards where you will take next week's exam 1, same as you do with your quizzes. Its only purpose is to let you practice file uploads which you must do for the problems which are of type "File Response".
b. Monday's lecture has been posted.
