**February 18**

Dear PHY 231C students,

At the end of this message is your personalized summary of

your scores on the work you have completed through last

week's Correction exam. In addition, I have used this data,

along with the course syllabus to give you a final grade

projection. The projection assumes your work in all

categories is represented by what you have done so far.

If you did not take exam 1, this will be your one dropped

exam. However, this does not give me sufficient data to

project a final grade and it will show up as a zero.

Below I am including: your Exam 1 post correction score (in

percent); your projected midterm exam average in percent

(for now this is equal to your midterm 1 score -- it'll

likely change after future midterm exams); your homework

average through set 3 including the bonus questions in

percent; your pre-course concept test bonus to be added to

your final exam score (1 if you chose to participate, 0 if

you did not); your pre-course survey bonus to be added to

your final exam score (1 if you chose to participate, 0 if

you did not); your projected final exam score in percent

(this is the PRE-correction score on exam 1 plus any earned

survey/concept test bonus); your pre-course; your projected

final average in percent; and the corresponding projected

final grade based on the criteria outlined in the syllabus.

These projections assume ALL future homework (both regular

and bonus), exams and corrections exams are represented by

the work you have done thus far. Clearly, if any future

work in any of these categories changes, your actual

scores/grades in some or all of these projected categories

will change as well.

Thus far, we have had 89 regular homework questions and 16

bonus questions. So, there were a maximum of 105 homework

points you could have earned through set 3; but your percent

score is based on 89 points as stipulated in the syllabus.

Anyone with homework points earned over 89 points, through

set 3 received a homework percent greater than 100%!

Here is the key to interpret my abbreviations below:

HW%: Homework percent (including bonus questions)

PMTA%: PROJECTED midterm average of all midterm exams in

percent (this is your post-correction midterm 1 score)

FE-CNPBonus Final exam pre-course concept bonus (1 if you

chose to participate, 0 if not)

FE-SRVBonus Final exam pre-course survey bonus (1 if you

chose to participate, 0 if not)

PFE%: PROJECTED final exam score in percent (your

pre-correction score on midterm 1 in percent plus any earned

concept/survey bonuses)

PFA%: PROJECTED final course average in %

Your projected final grade is: PROJECTED final grade

As an *example* of how your projections were calculated,

here is a calculated projection based on the current class

averages in each category (this calculation is based on the

class average, not your personal projection -- the bottom of

the email sent to your Lon-Capa account for your personal

projection):

The class average on the homework through set is 103% The

class average on the midterm, pre-correction is 65% The

average on the correction exam is 92%. The corrected

midterm average is 70%. The average concept bonus is 0.85

and the average on the survey bonus is 0.90. The class

average projected final exam score is 66.75% (including

bonuses).

First, we need to find the post-correction midterm score for

our class average (only your post correction score is shown

below):

MTcorrected = 65% + 0.3*(92%-65%)= 73.1%

Using these averages, we can project a final average and

grade in the course. In this projection and in your

personalized projection at the end of this message, we'll

make a these assumptions:

1. Assume homework and bonus point performance for the

remainder of the course remains as it has been thus far.

2. Assume the average final exam percent score is the same

as the average PRE-correction midterm percent score plus any

earned final exam bonus points.

Again, if the actual performance differs from these

assumptions, the actual scores will change too.

Homework is weighted at 25%, the midterms at 40% and final

exam 35% (including concept test and survey participation

bonuses). So, this average set of scores yields:

Projected final class average: 0.25*103% + 0.4*73.1% +

0.35*(65%+0.85%+0.90%) = 78.4%

Using the grading criteria in the syllabus, we see this

projected final average for this hypothetical average

student is 78.4% and is well above the

cut-off for a 3.0. It is alos *significantly* above the

historical average for

this class and its traditional equivalent. Again, the above

are all CLASS AVERAGES -- your personalized scores are at

the bottom of this message.

Lastly, a solution to this exam is now available in

Lon-Capa. It is in the form of a recorded video solution, a

reference to an online lecture where a substantially similar

example is already available or a reference to the required

text where a substantially similar example is available.

Dear PHY 231C student,

You can now view your midterm exam and your score in Lon-Capa. To see your

score, select: "View current problem status and grading information" from the

main menu. Next to MIDTERM 1 you will see your total points out of 50.

To review your version of the exam in Lon-Capa, click on Course Contents. Then

open the folder labeled EXAMS. The midterm is inside a second folder labeled

MIDTERM 1. You can view an individual problem on the exam, including your

response and the correct response by clicking on the problem (some problems you

can only see your response by clicking on the "Previous Tries" link at the

bottom of the problem's page).

You can prepare a printout of your version of the exam using the "print" option

in the upper right-hand corner of your screen; this option is visible when one

of the problems on the exam is opened/visible on your screen and selecting this

will allow you to create a pdf of your version of the exam. This will show you

how many points each problem was worth. On the original exam, you receive credit

for every correct response.

I encourage you to complete the correction exam available now as a homework

assignment. Doing so can improve your score on this exam; details are in the

message sent to you last week and in the syllabus.

It is your overall score on both the correction exam and original exam which

determines your bonus added to your original score; so complete all problems on

the correction exam (not just the ones you answered incorrectly on the exam you

took with me or a proctor)!

If a correction exam score is higher than your original score, then 30% of the

difference between the correction exam score and your original exam score will

be added to your original score as a bonus. For example, if your score on

today's exam is 40/50 and the correction exam score is 50/50, then 0.3*(50-40)=3

points will be added to today's score for an exam total of 43 points. So, 43/50

will be used as the midterm exam score for final grade calculation purposes. If

the correction exam is equal to or lower than your original score, then the

original score will be used for final grade calculation.

The correction exam is a different randomization than the original exam. So,

just like everyone receives different given values on homework problems, your

correction exam and your original exam will differ slightly.

The correction exam is due tomorrow, TUESDAY, Feb. 12 at 11:59 PM.

If your exam correction exam or your exam score are not showing up, try exiting

Lon-Capa, shutting down all windows of your internet browser and then re-logging

into Lon-Capa.

**February 7**

Dear PHY 231C student,

The correction exam/bonus point opportunity associated with exam 1 is now open

and available for you to complete. The Correction Exam is optional. If you

don't touch it, you will NOT lose any points from your in-class exam. If your

performance is better on the Correction Exam than on the in-class exam, then 30

percent of this positive difference will be added to your in-class exam score as

a bonus.

As an example, say your score on this evening's exam is 60% and you complete the

entire correction assignment with a score of 100%, then 0.30*(100-60)=12% would

be added to tonight's score for an exam 1 score of 72%.

The best strategy is to solve the Correction Exam perfectly to maximize your

gain. It is due next Tuesday, February 12 at 11:59 PM.

Exam 1 courtesy notice 3 of 3

Dear PHY 231C student,

I'm sending this as a separate message for emphasis. Your note sheet for this

(and all) exam(s) must be handwritten and original (no copies or printouts).

This is stated both in the syllabus and in the exam announcement. The use of

any other type of notes (i.e. not handwritten) is cheating. Any student using

any notes on an exam that are not handwritten will receive a penalty grade of

zero on the exam.

Penalty grades cannot be used as a dropped exam.

Your note sheet will be checked at least once during the exam.

Richard Hallstein

Exam 1 courtesy notice 2 of 3

Dear PHY 231C students,

In preparation for next Thursday's exam, I wanted to give you some additional

information. First, if you have not done so, you should review the study

suggestions in the syllabus:

https://web.pa.msu.edu/courses/2019spring/PHY231C/Study/Study.htm

I'll reiterate one point in this forum. In general, all of our exams will be

organized in the order the material is covered in class. This will help you in

both organizing a good set of handwritten notes and with recall when taking the

exam. One caveat to this organization style, sometimes the most challenging

question on an exam is early on the exam. If you're stuck on such a question,

make an educated guess and move on (don't use all your time on one question).

The practice exam problems for the first exam are now available. You can find

details in the syllabus here:

https://web.pa.msu.edu/courses/2019spring/PHY231C/Study/Study.htm

For next week's exam, here is how points are distributed:

Question on exam cover: Students may use one and only one sheet of original

handwritten notes on each of our MIDTERM exams. This single sheet must be

8.5inches by 11inches or smaller. Students may use both sides of this sheet. No

other notes are permitted. Is this true? The answer is YES and it is the only

available response: 1 point

1D motion: 15 points

2D motion: 16 points

Force: 18 points

On this and all exams, you are also responsible for units and common metric

conversions for all topics.

Richard Hallstein

Exam 1 Courtesy notice 1 of 3

Dear PHY 231C students,

The first exam will be on Thursday, February 7 from 7:45PM until 8:35PM in

Chemistry (CEM) room 138. The exam will be handed out promptly at 7:45PM;

students arriving after 7:45PM will not be permitted to enter the room until

after the students who arrived promptly have started the exam.

The exam will cover everything through and including online lecture 4 (homework

set 3). It will be based on the readings, the online lectures, and the homework.

Some of the problems will be conceptual in nature and some will have numerical

answers. There are a total of 17 separate responses on the exam. There are 50

possible points on the exam.

The exam is closed book, but you may use one 8-1/2 inch x 11 inch or smaller

sheet of original HAND-WRITTEN notes and equations. You may use both sides of

your note sheet. Your note sheet will be checked at least once during the exam.

Any notes other than described in the syllabus and restated here will be

considered a violation of the university's policy on academic integrity. As

such, a non-droppable penalty grade of zero for the exam will be given and an

official report of academic dishonesty will be filed with the university.

You should bring a few sharpened number 2 pencils, your student ID (or driver's

license) and a calculator (graphing calculators are OK). However, the use of

cell phones, PDAs or computers for any reason is NOT permitted. Pencils and

calculators will NOT be provided. Also as a courtesy to your fellow students,

you should turn off all cell phones and pagers before entering the room. When

taking the exam, all baseball caps or brimmed hats must be removed or turned

backward. Furthermore, all caps or hats covering the ears must be removed.

When you enter the room, sit in the row assigned to you based on your last name

(seating assignments will be displayed on the screen at the front of the room).

DO NOT open the exam until you are told to do so by an instructor. However, once

the answer sheets are handed out complete the student information section of

your answer sheet. Make sure you include your student ID number and your name on

the answer sheet. Make certain that your exam has your name and picture on the

cover sheet -- if it does not, you have the wrong exam! When you are finished

with the exam return both your answer sheet and your exam to an instructor or a TA.

You will have fifty minutes to complete the exam.

The whole exam will be assigned again in the same form as a homework assignment

as a Correction Exam. The Correction Exam is optional. If you don't touch it,

you will NOT lose any points from your in-class exam. If your performance is

better on the Correction Exam than on the in-class exam, then 30 percent of this

positive difference will be added to your in-class exam score as a bonus.

The best strategy is to solve the Correction Exam perfectly to maximize your

gain. The Correction Exam will be available in the morning on Friday,

February 8 and will be due on Tuesday, February 12 at 11:59 PM.

Some useful information is included on the cover page. The cover page for the

exam will contain the same information as is displayed on the practice exam's

cover page. The two sets of practice exams were outlined in an email sent

earlier today.

Note: the exam cover page is for all of the mid-term exams and not all of the

useful information listed on it is applicable to this exam.

The due date for Homework set 4 is Tuesday, February 19 at 11:59PM. This set is

a long set, so you should get started on it early.

PHY 231C course contact info, discussion board and help room (message 6 of 6)

Dear PHY 231C student,

If you have an administrative question about the course, please send it to:

phy231c-adm@pa.msu.edu Under no circumstances should requests for assistance on

homework and/or explanations of the online lectures be sent via email. Such

requests will likely go unanswered. With over five hundred students in the

course and the second semester course, it is simply impossible to answer all

potential homework questions individually via email. Instead, use the post

discussion option available on all lectures and on all regular homework

problems. This option also allows all to benefit from all such questions and

subsequent responses. These response could come from course staff or other

students.

You are encouraged to use the discussion board inside LON-CAPA. If you don't

understand a problem or you need help, just click on the "Post discussion" link

and post your question. Try to make your post as well articulated as possible;

be specific in your request. Statements like "help" or "I don't understand" do

not give us any idea about what is giving you difficulty. Again, do not use

email for help on the homework questions. More likely than not, others

will have the same question and unlike email, everyone can then benefit from

your question and the subsequent response(s). If you know the answer to a

fellow student's question, just post your answer. Please refrain from simply

posting a formula without any context or discussion. Quite often, the person

posting such a formula understands where it came from and would be able to find

a similar relationship when encountered on say, an exam. Whereas, those using

such a formula without understanding where it came from are quite often lost

when encountering the similar question on an exam.

You are encouraged to come to the Strosacker help room with your questions. Our

Teaching Assistants will be more than happy to assist you in finding your way to

the answers to our homework questions. However, they are instructed not to

simply solve these problems for you. Starting Monday, 1/14 the Strosacker help

room is in 1248 BPS and is usually open from 9:00AM to 9:00PM Monday through

Thursday and 9:00AM-6:00PM on Fridays. You are welcome to go to the help room

during any of its open hours, but there will be designated times when TAs

specifically assigned to PHY231/231C will be available. We will send you an

email when regular help room hours begin and when we have 231/231C specific

hours set.

PHY 231C Extra credit and not for credit items (message 5 of 6)

Dear PHY 231C student,

The practice exam problems provided are to help you in preparing for our exams

and are not for credit. Details are outlined in message 4 of 6 on exams and

practice exams.

The only bonus or extra credit opportunities offered in this course are as follows:

There are two optional pre-course extra credit/bonus point opportunities

currently available for completion. They are a timed pre-course concept test

and an untimed pre-course survey. These should be completed by 11:59PM on

Tuesday, January 15. A similar post course concept test and survey will be

offered over the weekend preceding our final exam (these also include a

participation bonus). We encourage you to complete them, as in addition to the

bonus outlined below, they will be used to help make future versions of this

course and its traditional equivalent.

Bonuses for concept tests and surveys:

Concept tests:

Do neither: no bonus

Do only 1(pre or post): 1 point added to final exam score

Do both (pre and post): 3 points bonus added to final exam score

Surveys:

Do neither: no bonus

Do only 1 (pre or post): 1 point added to final exam score

Do both (pre and post): 3 points bonus added to final exam score

The final exam has 100 points and is weighted at 35% of the final grade. Doing

all of these items will add 6 points for a maximum possible score of 106 (out of

100).

The extra credit for the surveys and concept tests are for participation only

and not for correctness. However, however in the case of the concept tests a

serious effort must be given to get the credit. As such, simple submission

patterns (like AAA..., or BBB...) or rapidly clicking on any response throughout

the concept test are not considered serious efforts and no bonus will be given.

There are bonus questions in the online lecture folders. You should be able to

answer these after completing the assigned reading from the required text and

watching the online lectures. These bonus questions are programmed to look like

exam questions, as such, they are all multiple choice. In addition, some of

these bonus questions are questions used on previous exams for this course and

its traditional equivalent. Lon-Capa's feedback option is disabled, so unlike

regular homework problems, Lon-Capa will not tell you if you have the correct

answer until after the due date. In addition, the discussion board on these

questions has been disabled. These questions are meant for you to work out

yourself after having read the assigned reading and watched the online lectures.

All points earned here will be added to your total homework points as a homework

bonus (so, homework scores over 100% are possible). Hints and/or solutions to

the bonus questions will not be provided.

The midterm exam will have a correction exam assigned as a homework assignment

in Lon-Capa. 30% of the positive difference between the correction exam and the

in-class exam will be added to your in-class exam score as bonus. As such, the

correction exam homework assignment can only add points to your midterm exam

score. Only students taking the original exam will have access to the correction

exam. The correction exam will be available at noon on the day after the

scheduled exam and will be due at the regular homework due date/time the

following week.

No other bonus or extra credit opportunities will be offered.

PHY 231C exams and practice exam problems (message 4 of 6)

Dear PHY 231C student,

There will be three midterm exams and one final exam for this course. The

midterm exams are scheduled as follows:

Midterm 1: Thursday, February 7 at 7:45PM Location: Chemistry(CEM) 138

Midterm 2: Thursday, March 14 at 7:45PM Location: Chemistry(CEM) 138

Midterm 3: Thursday, April 4 at 7:45PM Location: Chemistry(CEM) 138

Final exam: Monday, April 29 at 8PM Location: TBA

An alternate exam time will be provided for University approved reasons only and

prior to our scheduled exam. An alternate session will be offered for class

conflicts only. If you have a class scheduling conflict, you will need to

provide documentation of the conflict (a screenshot of your official class

schedule not the bar graph version, rather the version showing actual start

and end times) and I will arrange an alternate time for the exam earlier in the

day (possibly as early as 6:30AM). If the conflict is work related, you have

plenty of notice and you should make arrangements with your employer to get this

time off. If you have a class conflict with any of our midterm exams, you will

need to provide documentation of your schedule well in advance of the exam so

alternate accommodations can be made. In order to make arrangements for the

semester, we will need this information no later than Monday, January 21 . If,

you have a University approved conflict for the final exam (three FINAL exams on

the same day or another exam at the same time), you will need to provide

documentation of the conflict no later than Friday, March 15. Since the dates

and times of *all* final exams for *all* classes are currently available,

requests and conflict documentation received after this date will not be

honored. The alternate final exam will be at 7:45AM on Tuesday, April 30.

Again, you should know the times and dates of all your exams now, so there is no

reason to delay notifying us of conflicts.

There are no makeup midterm exams. However, if you miss a midterm exam for any

reason, you will be allowed to drop this exam and the midterm portion of your

final grade will be based on the other two midterm exams. Only one midterm exam

will be dropped. If you take all three midterms, your lowest midterm exam score

will be dropped when calculating your final grade. The dropped midterm exam

accounts for *all* unforeseen occurrences such as, illnesses, accidents, family

emergencies, etc.

In the case of missing the final exam, the MSU policy is: "A student absent from

a final examination without a satisfactory explanation will receive a grade of

0.0 on the numerical system, NC on the CR-NC system, or N in the case of a

course authorized for grading on the P-N system. Students unable to take a final

examination because of illness or other reason over which they have no control

should notify the associate deans of their colleges immediately."

If you are living or traveling far from the MSU campus at the time of an exam,

beyond a reasonable commuting distance, or if you are traveling with an

MSU-sponsored program, you may be able to arrange a proctored off-campus exam.

Arrangements must be made well in advance of the exam -- requests made after the

deadline posted in the syllabus will not be accommodated and you will have to

take the exam at MSU. For arrangement details and arrangement deadlines, see the

link in the exam section of the syllabus.

In Lon-Capa, there is a folder with practice exam problems. There are three sets

of practice problems these contain exam problems given in this course in each of

the two preceding academic years. The first includes every single problem from

midterm exams given in Fall 2016 and Spring 2017 in this course; the second

includes every single problem given on midterm exams in Fall 2017 and Spring

2018 in this course; and the third includes every problem given in the Fall of 2018 in this course. These problems are coded in Lon-Capa and appear in exam

mode for zero credit (no due date is set and correct/incorrect feedback is

disabled to allow you to return to the problem later). A second set of the same

problems is included with feedback enabled, so you can see if you answer these

questions correctly. The solutions to these problems take on one of three forms:

1. A reference to a very similar problem in the required text.

2. A reference to a similar problem worked out in the online lectures.

3. A new video solution.

You are encouraged to use these to help prepare for the exams. Try solving the

problems first before watching the solutions. Even if you answer the questions

correctly, you may find some additional useful information in the solution.

PHY 231C Readings, online lectures and bonus homework problems (message 2 of 6)

Dear PHY 231C student,

The assigned readings from our required text are outlined in the calendar

section of the syllabus. All of the online lectures and the associated homework

sets are now available in Lon-Capa. The Online Lectures folder contains the

lectures specifically designed for this online course; they are in the form of

narrated PowerPoint presentations with example problems and demonstrations.

Embedded within the online lecture folders are extra credit bonus homework

questions. These questions are optional and can only help your score in the

course. Most of these questions relate, at least in part to the assigned

reading and/or the online lecture immediately preceding the question. These

questions are programmed in exam mode (multiple choice) with correct/incorrect

feedback disabled; the correct answer will be available after the due date. The

discussion board on these bonus questions is disabled. No hints or solutions

will be provided for these extra credit bonus problems.

A reliable high speed internet connection is required, as is a computer with the

ability to view flash video. The computer will need a current, supported

operating system and a browser running HTML5 to use all the options available in

the online lectures.

PHY 231C is now available (message 1 of 6)

Dear PHY 231C student,

Welcome to the fall semester of PHY 232C – the course is now open and available.

You are receiving this message because you are enrolled in PHY 231C section 730 or section 731. Please read this message and the five subsequent messages carefully; they contain a significant amount of important information about the course. A copy of each is posted in the announcement section of the syllabus. We are sending these as separate messages to make it a bit easier for you to find specific information within an otherwise very long single message. The topics of these other five messages are: readings, online lectures and bonus homework questions; regular homework questions; exams, alternate exams and practice exam problems; extra credit and optional not for credit times; course contact information, discussion board and the physics help room.

The required text book is Rex & Wolfson: Essential College Physics, Volume 1. It is sold at the MSU bookstore, at SBS on Grand River and at many online retailers. This class will use LON-CAPA. LON-CAPA is a computerized homework and exam management system developed right here at MSU. We will NOT use d2L whatsoever in this course. Since this is an online class, you are not required to purchase an i-clicker.

Please visit www.loncapa.msu.edu and log in using your MSU Net ID and password. Select the "PHY 231C, Spring 2019 " class. The first item on the top is the syllabus. You can also review the syllabus without logging in to Lon-Capa here: https://web.pa.msu.edu/courses/2019spring/PHY231C/

Read *all* sections of it carefully. This is the official syllabus of the class and contains information like important dates (exams & homework), bonus point opportunities, homework information, exam information, grading, etc.

This is the only message(1 of 6) you will receive from us via the Registrar’s office mail system for this course. A copy of this message, as well as all future course messages will be sent to you via Lon-Capa’s mail system as critical messages.

To make certain you see these critical course messages, they will continue to pop up while you are in Lon-Capa until you move them to your Lon-Capa inbox. So, after reading the message, simply click the move to inbox button at the bottom of the message.
