Syllabus Description:

Welcome to PHYS 121A. My name is Marjorie Olmstead (pronouns she/her) and I will be your instructor. 

In this class everyone is welcome, regardless of other identities you hold in addition to that of physics student.  I expect everyone in this class to treat each other with respect.

 

Getting started

  • Read this syllabus page in carefully and explore the rest of the course Canvas site
  • Click on your settings in Canvas (top left picture of you), select “Notifications” then under “Announcements” select the checkmark to ensure you get announcements from me sent immediately not later in the day or later in the week.
  • Purchase your textbook and online homework system access (see "Course Material" below)
  • Click on the “MyLab and Mastering” link to activate your Mastering Physics homework link.   For more information on how to connect to the online homework system, see the instructions found here.
  • Click on the "Panopto Recordings" link in the left side navigation to activate your Panopto recording link
  • For labs, we will use Pivot to perform video experiments.  Note that you have already paid for access to Pivot through the course fee as part of registration.  Your TA will announce details on how to get access during the first week of the quarter.
  • Slack will be the primary space where you can communicate with your pod and your TA. To get started with this space, please:
    • Complete this survey, so that we can try to match you to a group of people you will learn with effectively, and who you feel more comfortable with.
    • Use your UW email to join our Slack workspace. Note that you will only see course-wide channels at first. Your TA will place you in a learning pod by the end of your first Tutorial session.
    • Get Slack running on your device. Here are useful tips and features for using Slack. We highly recommend downloading the mobile or desktop app, and turning notifications on so that you don't miss messages from your TA and other members of your pod.
  • Fill out this Enrollment SurveyLinks to an external site..
  • Find the video assignments via the Assignments or Modules links on the left. Watch the Introduction and Logistics videos and do the Sample Quiz embedded in the Logistics video.
  • Do the ungraded Physics Primer (not graded) on MyLab and Mastering to see if you need to review some math for the course.  If needed, watch the Math Concepts video to review the concepts of graphical representation, vectors and derivatives.
  • Join the course Zoom session on the first day of class.

Overview

This is the first of a three-quarter sequence of introductory calculus-based physics. You should find this course challenging and stimulating, and I hope that you also find it interesting and enjoyable. Upon successful completion of this course, you will be able to develop calculus-based models to describe the physical world pertaining to the following:

  • one dimensional motion
  • momentum
  • energy
  • forces
  • motion in two or more dimensions
  • rotational motion
  • gravity

This course has multiple components lecture, lab, and tutorial (QZ section in time schedule) each of which has several important aspects.  These are described below after some general information critical to success in this course.  The only required synchronous activities are tutorial and exams.  All other required activities are asynchronous (i.e., complete at your own pace before the deadline).  

Resources to Succeed

This website describes recommended practices to succeed in this course, and contains a list of resources you may find helpful for a variety of issues students may encounter during your time at UW.  Contact me if you need help finding the resources you need.

One very important practice described in the above website is working collaboratively.  You will be matched with a small group of your peers in your current Physics 121 tutorial (QZ) section to form a “learning pod” that you will work with in Physics 121. You will work together during Tutorial sessions, and we encourage you to collaborate on other aspects of the course. You and your pod will be working with a single TA for all aspects of the course.  Slack, the collaboration platform we have picked for this class, will be the primary space where you can communicate with your pod and your TA.

Office Hours and Posting Questions

During the week the TAs and I will hold office hours on Zoom where you can ask questions.  Click "Office hours" in the menu on the left for the office hour schedule. 

Use Slack for physics questions or syllabus related questions.  Students are encouraged to answer each others' questions, but the TAs and I will also monitor this frequently and will respond if needed. 

Contact information

For questions send an email with your course and section (Phys 121A), your UW netID (the part before @uw.edu in your email address), and name as it appears on Canvas to:

  • Me (Marjorie Olmstead) via Canvas mail (click "Inbox" in the left-most menu) for personal correspondence related to grades, health issues, etc. If I don't reply there within 1-2 days, you may also try contacting me by email at olmstd@uw.edu.
  • the program coordinator at phys1xx@uw.edu for administrator questions related to registering, overloading, etc...
  • your TA (contact information here) for other questions.
  • the TA coordinator (Peter Shaffer) at uwttl121@uw.edu for questions about your TA, or questions about lab or tutorial your TA may not be able to answer.

Course Material

You need to purchase the following items:

Class components

This class consists of lecture, lab, tutorial and exam components.  You can see all the components required in a given week by clicking "Modules" in the menu on the left.  Note that assignments are listed in the week when they are due; you may want to start them in the previous week.

At the nominal class time, 8:30-9:20 am MW, Prof. Olmstead will hold open office hours/discussion via Zoom.  You are encouraged to work through course materials during those times and jump onto Zoom with your questions.  Friday class time is for one-on-one appointments, scheduled via the Canvas Calendar.  Weekly Schedule.

Important Note: Since each exam includes questions based on the lectures, labs, and tutorials, missing a lecture, lab, or tutorial section can have an impact on your exam performance.  You should be sure to watch all lectures, and work through any lab or tutorial that you miss as soon as possible to minimize the impact on your course grade.

Lecture components:

Before each scheduled lecture you need to complete the assigned reading (see schedule).  The lectures include the following graded components:

  • Lecture reading discussion (4% of grade):
    • After completing the reading you need to complete the associated discussion assignment before 5 pm on the day of the assigned reading (Monday, Wednesday, and Friday).
    • These are graded based on a thoughtful attempt, not on correctness, and you will be given credit for either asking a question, answering a previous question, or discussing a part of the reading you found particularly interesting.
    • This is a place for you to answer your fellow students questions about the reading.  The TAs will read these to get a sense of common questions, and I will post a general response video, but we will not respond to individual questions.
    • Your lowest three reading discussions will be dropped.  If you miss more than three due to a valid reason (family and medical emergency etc), please contact me.
  • Lecture video engagement (4% of grade):
    • After completing the reading the you need to watch the lecture video and complete the embedded quizzes before 5 pm on the day of the assigned reading (Monday, Wednesday, and Friday).
    • These will be graded based on engagement, not on correctness.
    • Your lowest three video quizzes will be dropped.  If you miss more than three due to a valid reason (family and medical emergency etc), please contact me.
  • Lecture homework (8% of grade):
    • These will be due on Tuesdays at 5 pm, and will be based on material covered in the previous weeks reading and video.
    • You can access the lecture homework by clicking "MyLab and Mastering" in the menu on the left.

Lab components:

  • Labs (12% of grade):
    • There are eight graded lab assignments, some of which may have multiple parts.
    • Each lab assignment under "Assignments" tells you the parts to be completed in Pivot.  The overall schedule is here.
    • The labs are due Wednesday at 5 pm.  Before then you need to collect and analyze data from video experiments on Pivot and answer questions based on your work.
      • After you start any of the assignments, you can save your work and go back to it as many times as you want before the deadline, thus, allowing you to talk to peers or a TA, and then go back and finish.
    • Each lab assignment will be graded based on the following:
      • Adequate (2 points): All questions answered thoughtfully, and measurements closely match those expected.
      • Needs improvement (1 point): Some questions could use more explanation, and/or some measurements do not match those expected.
      • Inadequate (0 points): Lab not done or many questions could use more explanation, and/or many measurements do not match those expected.
    • If you receive 0 points or 1 point, you can do or redo up to 2 labs without asking for permission.
      • After the deadline, you will temporarily no longer be able to submit new work. Once the lab has been graded, it will be reopened, and you can complete missing work or change your responses based on feedback.  You need to contact your TA to make sure that they grade the new work.
    • If you need to make-up more than 2 labs due to a valid reason (family and medical emergency etc), contact me.

Tutorials components:

The list of tutorials and the weeks they will be covered is here.  A calendar showing tutorial times is here.  Tutorial starts on Oct 5 (i.e., tutorials do not meet on Oct. 1).

The tutorials include the following graded components:

  • Tutorial pretest (1% of grade):
    • These are designed to get you thinking about your ideas on topics covered in this course.  They are graded based on a thoughtful attempt, not on correctness.
    • These become available Friday at 3:30 PM and are due on Monday at 5 pm.
    • Once you start a pretest, you will have 15 minutes to complete it without the ability to pause.
    • Your lowest tutorial pretest score will be automatically dropped.
    • If you miss more than one tutorial pretest due to a valid reason (family and medical emergency etc), please contact me.
  • Tutorial in-class (3% of grade):
    • You need to attend and actively participate in discussion at your tutorial section (QZ section on time schedule) each week to get participation credit.  Each tutorial will be graded based on the following:
      • Adequate (2 points): Actively engaged in discussion throughout tutorial.
      • Needs improvement (1 point):  Multiple periods not engaged in discussion during tutorial.
      • Missing (0 points): Did not attend any tutorial section.
    • If you cannot attend your tutorial section in a given week, you can attend another section.  A schedule of tutorials with their Zoom links can be found here (select "12x" then select "121 Tutorial Schedule").  Be sure to contact your TA to let them know.
    • Your lowest tutorial in-class score will be automatically dropped.  However, you are still responsible for submitting the associated tutorial homework on time.
    • If you miss more than one tutorial in-class due to a valid reason (family and medical emergency etc), please contact me.   
  • Tutorial homework (8% of grade):
    • Each tutorial has homework that is due at 5 pm the Monday after you have worked through the tutorial.
    • You need to upload a scanned pdf file to the Canvas tutorial homework assignment.
    • You can submit one tutorial homework up to one week late without asking for permission and with no penalty, but you need to contact your TA to make sure they grade it.
    • If, due to a valid reason (family and medical emergency etc), one homework needs to be submitted more than one week late, or more than one homework needs to be submitted after the deadline, please contact me.

All important tutorial information can be found under the "Tutorial Information" menu on the left.  Once at the tutorial website select "12x" for information general to all courses in the Phys 121-122-123 sequence.  Select the link for section A under "PHYS 121" to get the schedule for all assignments specific to your class.

Exams:

Exams will be done online.  The exam procedure is described here.

The following dates are preliminary and may change.

  • Midterm exam 1 on October 29th starting between 4:55 and 5:15 pm (PDT). Once you start the exam, you will have 60 minutes to finish the exam.
  • Midterm exam 2 on November 19th starting between 4:55 and 5:15 pm (PST). Once you start the exam, you will have 60 minutes to finish the exam.
  • Final exam on one of the following dates. Once you start the exam, you will have 110 minutes to finish the exam. You will be graded on the first exam you access.
    • Tuesday, December 15th starting either between 8:25 and 8:45 am (PST)
    • Wednesday, December 16th starting between 8:25 and 8:45 am (PST)
    • Wednesday December 16th starting between 4:25 and 4:45 pm (PST)

Note that there are no make-up exams.  So, students with outside professional, service, or career commitments (i.e. military service, ROTC, professional conference presentation, NCAA sports, etc.) conflicting with the exam dates must contact me early in the quarter to establish alternate examination procedures.  Exam scores for students who miss an exam without making prior arrangements will be zero.

Each exam is out of 100 points, and has three components:

  • 70 points on lecture material
  • 15 points on tutorial material
  • 15 points on lab material

Exams will count for 60% of your grade.  Your overall exam score will be based on the best of the following two methods:

  • Method 1: 20% from each of your midterms scores and 20% from your final exam score
  • Method 2: 20% from your best midterm score and 40% from your final exam score

We will design the exams such that a student who understands some of the material very well but needs some improvement in the remaining material should get a score around 65%.  If the class average on a given exam is less than 65%, then all the scores for that exam will be adjusted upward so that the average is 65%. Scores will not be adjusted downward even if the class average is higher than 65%.

If a student is found responsible for misconduct during an exam, a score of zero will be given for that exam for this student.  If the misconduct occurs during a midterm, only Method 1 is used to calculate the final grade, and Method 2 is not used.

Grades

You will get a grade of 0 for the entire course if either of the following criteria are met:

  • You receive 0 points for 3 or more lab assignments.
  • You receive less than 9 out of the 16 points possible on the lab assignments.

Otherwise your final weighted percentage is converted to a grade point using the following thresholds.

grade point course score   grade point course score   grade point course score   grade point course score
4.0 92.0 3.0 76.0 2.0 60.0 1.0 44.0
3.9 90.4 2.9 74.4 1.9 58.4 0.9 42.4
