The letter grades at the end of the course are curved, however 55% is passing.  For those who do pass, we give, very roughly, equal numbers of As, Bs and Cs.   We do use + and – as well.  

What if I have to miss a class where there is graded material?


The grading concept is this:

30% of your grade is related to your effort, 70% to your understanding.   Effort is measured in 4 things:

1.   Pre-lecture reading Quizes: 10% 

You have to read the chapter(s) before Monday lecture.  There will be a multiple-choice quiz on line, via Sapling, and it's due Sunday night, before the lecture.   The 10% is based on you getting 3 points per week.  The sapling quiz is worth 5 points.   That's a bonus, and you can carry it forward.

2.   Homework 10%

In Wednesday recitation, you are responsible for doing ALL the assigned problems.  Only one will be collected, but your TA will decide that in recitation.   (So do them one per page)  You may not ask your TAs how to do the homework prior to the recitation itself--that's what recitation is for.   A perfect answer is worth 3 points.  ANYTHING handed in is worth 1.   The 10% is based on the 3 points.    On the Friday recitation  we will do review problems, which will be like the free response exam problems or in-class quiz problems, as well as any on-line problems you had trouble with on the HW.  Just like exam problems, they cover multiple chapters.   Think of them as early (and repeated) review for the exams.

3.   Sapling Bonus points.   

You will also have 3 bonus-point on line problems (Sapling):  due Tuesday,  Thursday, and  Friday.   Like learning a language, frequent repetition is  helpful.   That's why they are  posted only one day ahead:  we  want you to practice this skill daily if possible.   If you can't get to it, of course, remember it is extra credit, not mandatory.   Get all three right (Sapling grade =5 for each), and it translates into  3 bonus points in our scoring system.    (like a perfect homework problem).  

4.      Labs 10%

There will be a quiz at the start of lab: 3 questions about the lab you are to do. That's the 10%.   The purpose of the labs is to reinforce the lecture material through hands-on experimentation. It is not to teach you how to do lab reports:  Bio already taught you that. Thus, although there are no lab reports, we expect you to understand the material before you leave, and the TA will check you out.   IF YOU LEAVE WITHOUT BEING CHECKED OUT, YOU LOSE CREDIT FOR THE LAB.

Note that you NEVER have to hand in any "Pre-Lab" material, no matter what the write up says. 

Because of our bonus system, you could theoretically accumulate more than 30 POINTS, but this part of the course is capped at 30% of your grade.  You can think of the bonuses like an insurance policy, for when a particular lab has tricky questions, or you totally misunderstand a homework problem. 

Reading Quizes: 10%

Homework 10%

Quizzes 10%

Labs 10%

2 Midterms: 30% (15% each)

These are given in the lecture period that week.

On those weeks there is no lecture, but you are still responsible for reading the chapters and doing problems in recitation.

What if I fail a midterm?

Final: 30%    (cf. our Spring Senior policy below)

Advice:   save all your returned, graded papers.  If there is any doubt at the end of the course, it is valuable that you show what papers you got back.   We have a LOT of graded material, so occasional errors happen copying grades.  You don't want to say "I got 86 on the first midterm, not 68" and have no way to prove it.

Cheating:   We follow the University guidelines.   If you are caught, your grade in that test becomes zero (and in Midterms, no reset option.)  Depending on the degree of premeditation we observe, you may also have your course grade set to an F and no option of withdrawal.   This course has an elaborate safety net to eliminate your perceived need to cheat.   Don't be stupid and cheat.  We will catch you.

Sapling License: To register go to: https://community.macmillan.com/docs/DOC-5972-sapling-learning-registering-for-courses

You can also purchase access through the bookstore.
  The ISBN for the multi-term Sapling physics is  9781319079901
 However, it may cost you more than $60 due to the bookstore's own markup for handling the transaction.  

HELP!   Any issues during sign up, or throughout the term can be addressed by phone or by webform via the Student Support Community. https://community.macmillan.com/docs/DOC-6915-students-still-need-help

Once you have registered and enrolled, you can log in at any time to complete or review your homework assignments.

Missing Grades:  the main rule is that we do not make up missed material, since we have such an extensive data base of your performance. Here are some specifics:

Homework: We NEVER accept late homework. You can always hand it in early if you have to be away. If you have some emergency, we will discount that assignment --and your HW grade (10%) is then based on all the other homeowork.

Friday Quiz: Same as Homework. No makeups, ever.

Online Reading Quiz for Lecture-- Same as homework.

Labs: NO MAKE UP LABS. A valid excuse will be needed; your other labs therefore count more.

Midterms: Again, we do not do makeup midterms. If you miss one, AND HAVE A VALID EXCUSE, then the other carries the weight for your entire midterm grade.

Final: OK, we'll work out an option if you have an iron-clad excuse. Leaving early for the term break is NOT one of those excuses.

Midterm Reset Any student may apply for a ONE TIME midterm grade reset to 55, the passing grade.   This may not be used on both exams, just one. 

To get reset to 55 points on a given midterm, all incorrect multiple choice questions must be explained fully, in writing, and submitted at least 24 hours before the next exam (Midterm 2, or Final).Example:  A student gets 35 points on a midterm.   She got 20 points in free response, and 15 points in multiple choice--that is, she got 3 right out of 15 questions.  She then needs to explain the other 12 MC questions, to get the extra 20 points.  If she messes up 4 of those 12 questions, she then gets only 20 x (8/12) = 13 extra points, or a partial reset. 

Since this is a one time option, you may not want to squander it if you got, say, a 53 on the first Midterm. 

Senior Policy

(Spring only)  Seniors graduating this Spring can have their two midterm exams count for 30% each, in lieu of a final.    This includes midterm reset .
