+### Introduction
+We are committed to creating a friendly and respectful place for
+learning, teaching and contributing.  All participants in our course and
+communications are expected to show respect and courtesy to others.
+
+To make clear what is expected, everyone participating in DSCI 100 activities
+is required to conform to the Code of Conduct.  This Code of Conduct applies to
+all spaces managed by DSCI 100 including, but not limited to, class meetings,
+email communication, and online forums such as Piazza and GitHub. The DSCI 100
+teaching team are expected to assist with the enforcement of the Code of
+Conduct.
+
+The DSCI 100 Instructor(s) is responsible for enforcing the Code of Conduct.
+All reports will be reviewed by the Instructor(s) and will be kept
+confidential.
+
+### The DSCI 100 Code of Conduct
+We are dedicated to providing a welcoming and supportive
+environment for all people, regardless of background or identity. As such, we
+do not tolerate behaviour that is disrespectful to our teachers or learners or
+that excludes, intimidates, or causes discomfort to others. We do not tolerate
+discrimination or harassment based on characteristics that include, but are not
+limited to, gender identity and expression, sexual orientation, disability,
+physical appearance, body size, citizenship, nationality, ethnic or social
+origin, pregnancy, familial status, veteran status, genetic information,
+religion or belief (or lack thereof), membership of a national minority,
+property, age, education, socio-economic status, technical choices, and
+experience level.
+
+Everyone who participates in DSCI 100 activities is required to conform to this
+Code of Conduct. It applies to all spaces managed by DSCI 100 including, but
+not limited to, class meetings, email communication, and online forums such as
+Piazza and GitHub. The DSCI 100 teaching team are expected to assist with the
+enforcement of the Code of Conduct. 
+
+#### Expected Behavior
+
+All participants in our events and communications are expected to show respect
+and courtesy to others. All interactions should be professional regardless of
+platform: either online or in-person. In order to foster a positive and
+professional learning environment we encourage the following kinds of
+behaviours in all DSCI 100 events and platforms:
+
+- Use welcoming and inclusive language
+- Be respectful of different viewpoints and experiences
+- Gracefully accept constructive criticism
+- Focus on what is best for the community
+- Show courtesy and respect towards other community members
+
+Note: See the [four social rules](https://www.recurse.com/manual#sub-sec-social-rules) for further recommendations.
+
+#### Unacceptable Behavior
+
+Examples of unacceptable behavior by participants at any DSCI 100 event/platform include:
+
+- written or verbal comments which have the effect of excluding people on the basis of membership of any specific group
+- causing someone to fear for their safety, such as through stalking, following, or intimidation
+- violent threats or language directed against another person
+- the display of sexual or violent images
+- unwelcome sexual attention
+- nonconsensual or unwelcome physical contact
+- sustained disruption of talks, events or communications
+- insults or put downs
+- sexist, racist, homophobic, transphobic, ableist, or exclusionary jokes
+- excessive swearing
+- incitement to violence, suicide, or self-harm
+- continuing to initiate interaction (including photography or recording) with someone after being asked to stop
+publication of private communication without consent
+
+#### Consequences of Unacceptable Behavior
+
+Participants who are asked to stop any inappropriate behavior are expected to
+comply immediately. This applies to any DSCI 100 events and platforms, either
+online or in-person. If a participant engages in behavior that violates this
+code of conduct, the teaching team may warn the offender and or engage the DSCI
+100 Instructor to investigate the Code of Conduct violation and impose
+appropriate sanctions.
+
+### Incident Reporting Guidelines
+
+If someone violates the Code of Conduct during a DSCI 100 event or in an online
+space outside of organised events, we ask that you report it to the
+Instructor(s). The current instructor(s) of DSCI100 is(are) Trevor Campbell. An
+email to trevor[-at-]stat.ubc.ca will be seen by Trevor Campbell. To report a DSCI
+100 code of conduct violation that will not be seen by your instructor, an
+alternative contact person is Bruce Dunham, Professor of Teaching in the
+Department of Statistics at UBC. His email is b.dunham[-at-]stat.ubc.ca.

+# COVID-19 Policy
+
+## Student health
+
+If you are sick, stay home. If you feel you *might* be sick, stay home.
+No matter what you think you may be sick with (cold, flu, food poisoning, COVID, *anything*),
+just stay home. Do not come to class if you have COVID symptoms, have recently tested positive
+for COVID, or are required to quarantine. **Stay home**.
+
+**Seriously. STAY HOME. You won't miss anything.**
+
+I will be posting recorded lectures to the Canvas page.
+
+All of your assignments can be completed remotely.
+
+I will drop your lowest worksheet and tutorial grade at the end of the semester.
+
+I will make alternate arrangements for those who are ill right before/during quizzes
+(either reweight grades, offer an alternate quiz time, etc.). 
+Please fill out an academic concession form (may be found on the Canvas page) and email
+it to me in advance of the quiz. 
+Per UBC policy, students who miss the final quiz must apply for deferred standing.
+
+**You are required to perform a daily self-health assessment before attending campus**. Every day,
+before coming to class, complete the self-assessment for Covid symptoms using
+[this tool](https://bc.thrive.health/covid19/en).
+
+**You can check [this website](http://www.bccdc.ca/health-info/diseases-conditions/covid-19/self-isolation#Who) to find
+out if you should self-isolate or self-monitor.**
+
+Your precautions will help reduce risk and keep everyone safer. 
+
+## Seating in class
+To reduce the risk of COVID-19 transmission, please **sit in the same seat/area in the classroom each day**. 
+This will minimize your contacts. 
+
+## Eating/drinking in class
+
+**Eating is not permitted in class.** Please avoid drinking. If you drink something in class,
+you must lift your mask only between sips (see below).
+
+## Interacting with Instructors
+**Do not approach the front of the classroom under any circumstances.** 
+In order to minimize contact, the teaching team will remain at the front of the classroom,
+and students will remain in the seating area. 
+You are welcome to raise your hand to ask questions while I lecture as usual.
+We will offer *assistance-at-a-distance (TM)* on your in-class assignments via Zoom with screen sharing.
+
+## Masks
+**Masks are required for all indoor classes** (per the BC Public Health Officer
+orders). A mask is a medical or non-medical device that covers *both* the nose and mouth.
+You must wear the mask for the full duration of in-class meetings.
+Please do not eat in class; if you need to drink water/coffee/tea/etc, please keep your mask
+on between sips. You may be asked to remove your mask briefly on occasion 
+(e.g., for an exam ID check), but otherwise, your mask should remain on.
+
+## Vaccination
+COVID-19 vaccines are available to you, free, and on campus. 
+See the [Vancouver Coastal Health page](http://www.vch.ca/covid-19/covid-19-vaccine). 
+The higher the rate of
+vaccination in our community overall, the lower the chance of spreading the
+virus. Please arrange to get vaccinated if you have not already done so. 
+
+## Instructor health
+**If I (Trevor, the instructor) become ill:** I will not attend the in-person class. If I am well enough to continue teaching,
+I will run the class remotely on Zoom. If I am not well enough to teach, I will find a substitute instructor
+who will run the class either in-person or online. You will be notified in advance as early as possible what the 
+plan is.
+
+**If a TA becomes ill:** they will not attend class.
+If they are able to continue their duties remotely, they will do so.
+If they are not, either another TA will fill in for them, or their work
+will be postponed until they are well.

+# What if my travel to Vancouver is delayed?
+
+**If you will be late by a few weeks:** don't panic! I will be posting
+recordings of the lectures to the Canvas page, and all of your coursework will
+be completed on our course server electronically, so you won't miss anything.
+
+**If you will be absent beyond Oct 8, please do not take this course.**
+You are required to be present in Vancouver for this course. We hold 
+our quizzes in-person (for *all* sections, online and in-person!), and attendance
+is mandatory. If you have concerns, contact science advising 
+and talk to them about your options.
+
+# What if I get sick during the semester?
+
+### DO NOT COME TO CLASS.
+
+I will continue recording and posting lecture videos on Canvas throughout the
+semester, so you will not miss anything.
+
+You can complete all of your assignments electronically (and remotely).
+
+I will drop the lowest worksheet and tutorial grade from the semester.
+
+# What if I get sick right before a quiz?
+
+### DO NOT COME TO THE QUIZ.
+
+I will make alternate arrangements if you get sick right before/during a quiz.
+Please contact me as far in advance as possible, and fill out an academic
+concession form (available on the Canvas page).
+
+# What is the structure of the class?
+
+Each week (starting on Thursday) will have the following pattern:
+
+- I will release pre-lecture reading material a few days earlier (usually on Mon/Tues)
+- In class on Thursday, I will begin with a brief lecture to introduce a new
+  concept. Then you'll do a worksheet to practice the concept.
+- Your lecture worksheet will be due Saturday at 11:59pm pacific time.
+- Then you'll have until the next tutorial with no lecture/tutorial assignments
+  due. Woohoo!
+- In class on Tuesday, the TAs will run a tutorial to reinforce the concept we learned
+  on Thursday. You'll do another worksheet to practice the concept. The
+tutorial worksheets are generally harder than the lecture worksheets.
+- The tutorial worksheet will be due at the beginning of lecture on Thursday.
+
+There will be 3 quizzes throughout the semester; the first two are held in
+class, and the last is during the exam period, but they'll all be the same
+format (unless otherwise notified).
+
+There will be a class project, which you will complete with a randomly-assigned
+group.
+
+# How do I submit an assignment?
+
+**Lecture / Tutorial Worksheets:** You must complete all of your lecture and
+tutorial worksheets on our JupyterHub server. Once you are done working, just
+go to File -> Save and Checkpoint, and make sure the checkpoint is "a few
+seconds ago" at the top of your screen. We will show you how to do this in
+class. You don't need to click "submit" anywhere -- our server will
+automatically take a snapshot of your assignment at the due date. Make sure you
+do not move / rename your assignment from where it originally was on the
+server.
+
+**Projects / other assignments:** You will submit these on Canvas.
+
+# How do I get my assignment regraded?
+
+*Per the syllabus:* ask the TA who graded the assignment to take a second look
+at it. You can post on Piazza using a private message to the teaching team and
+we will respond there.
+
+*Note:* We will only regrade to correct mistakes that we made when grading.
+Please see the syllabus for our policy regarding autograding.
+
+# Where do I find due dates?
+
+All due dates are listed on Canvas.
+
+# What if I registered late? When are things due?
+
+Hi! Welcome to DSCI100 -- glad to have you on board. Since we have a new
+assignment in every class session, there are already a few assignments to catch
+up on:
+
+If you registered after a class session already
+happened, then the assignment from that class session will be due exactly 1
+week after your registration date & time.
+
+
+If you registered before a class session happens, the
+assignment from that class is due at the normal time.
+
+# I'm going to be late / absent for a class! Who do I notify?
+
+I do not need to be informed when you'll be absent from a regular class. 
+I understand that, from time to time, you will not be able to 
+attend the lecture/tutorial sessions. There are no marks assigned 
+for attending class. I am hoping the
+flexibility of this course will allow you to access the learning materials
+wherever you are and whenever you need them. 
+
+If you are going to be absent from a quiz, you need to fill out a self-declared
+concession form in a timely manner prior to the quiz. See the course policies
+on the syllabus for details.
+
+# Do I satisfy the math requirement for this class?
+
+Yes. There is no hard math prerequisite; MATH12 (or equivalent) is suggested but not required.
+
+# How do I get help in the course?
+**During Lectures & Tutorials:** You can use lecture and tutorial time to ask
+questions, discuss and receive individual feedback regarding your worksheets,
+tutorials, or group project. Myself, the TAs and your fellow classmates will be
+available to help you work through the problems.
+
+**Office Hours:** The TAs and I will hold office hours at various times
+throughout the week via Zoom. I encourage you to ask
+questions about the worksheets, tutorials, the project or any other questions
+about the course material.
+
+**Piazza Discussion Board:** You can post on the Piazza Discussion board to ask
+your questions about the course material. You can also help your classmates by
+answering their questions.
+
+**Email:** **For questions about the course material, please post your questions on Piazza.**
+If you have personal questions that do not pertain to the course
+material itself you can email me. Please note: I respond to emails M - F,
+and I try my best to answer you as promptly as possible. However, given the
+large class size I may take a few days to respond.
+
+**Do not send me email at my `mail.ubc.ca` or `.ubc.ca` account; I don't check
+those. Please send it to the email address listed on the syllabus.**
+
+# How do I do well in this course?
+**Most importantly:** complete the lecture and tutorial worksheets. These
+are intended to help you learn the concepts so you'll do well on the project
+and quizzes. The worksheets tend to be a bit easier and provide more guidance.
+The tutorials are more difficult and give you a good sense for how well you've
+learned the material. Students who make an effort to complete all of the
+worksheets and tutorials tend to perform well in the class.
+
+For lecture/tutorial worksheets, you can collaborate with your peers (this is
+encouraged!) as discussing the material while you work on it will help you
+learn. But you are not allowed to simply copy another student's work. That is
+plagiarism, which is expressly forbidden in the course policy.
+
+Time management is very important in this course. There are regular assessments
+every week to keep you on track, but we move quickly and cover a lot of
+ground. 
+
+Take an active role in the learning community that we will build together. Ask
+questions on Piazza when you have them, and try to answer each others'
+questions when you can.
