Course Goals

  1. Stay physically and mentally healthy and maintain intellectual and personal connection in a time of dispersal and isolation.
  2. Experience the challenge, joy, and beauty of calculus.
  3. Improve your problem solving skills and mathematical confidence. Leave this course with an increased ability to do mathematics.
  4. Gain a firm, grounded, enduring understanding of two of the big ideas of calculus: limits and the derivative.
  5. Be able to correctly perform mechanical calculations using the course content, apply problem solving skills to new areas, and effectively communicate problem solving strategies in writing.
  6. Have fun while learning a lot.

Course Structure and Pacing

This is the twelfth time I've taught this course, so on the one hand I have a very good feel for how this will go. But this is my first time doing this class on zoom, so there are some things I am uncertain of:

  • It will take me a little while to get used to the mechanics of the class: writing with a sharpie on paper instead of a chalkboard, looking for questions in the chat, etc. Your patience and feedback is appreciated.
  • It will also take time for me to figure out the pace of the class: how much we can comfortably cover in sixty minutes on Zoom.
  • In addition to zoom, it is easy to for me to make videos presenting content or working through examples. We can adjust the ratio of recorded content to live zoom as needed.
  • This class meets three times a week instead of the usual two. This gives us of flexibility, room to experiment, and the ability to take a snow day or two.
  • Ruminations on help sessions are below in a separate section.

There are four parts to this class (corresponding to the first four chapters in the textbook), each with a distinct feel:

  1. Review of functions. This may seem both too slow and too fast at the same time. The last week of this part of the class is always difficult. Experience has shown, however, that the review of functions is definitely worth it. It is essential for the rest of the course.
  2. Introduction to the derivative. Here we will learn what the derivative is and what it means. This is more conceptual and sometimes seems odd to those used to less conceptual and more algebraic ways of thinking about math.
  3. Techniques of differentiation. Having learned what the derivative is, we now learn lots of short cuts to calculate it. This part of the class is the most traditional, in that you'll learn some formulas and techniques, and then do lots of practice of those techniques.
  4. Applications of derivatives. Here we will learn several different ways derivatives get used. This is the most applied part of the course. It is somewhat more difficult, but most students find it the most interesting, too, and a good way to end the class.

We will cover most of the first four chapters of the text, at a pace of approximately one section per class.

Class Meetings

  1. This class meets three times a week on zoom. Class sessions will vary in length but will almost never be more than an hour.
  2. Video stuff:
    • As much as possible, please keep your video turned on during class. This will help you stay engaged and will help me have a sense of how class is going. I have been teaching a long time and am generally good at gauging whether or not a class is following what I'm teaching. But I won't be able to do this if I'm looking at a screen full of black rectangles.
    • Of course if you have connection problems or if you need to turn the camera off for a few minutes, that's fine.
    • It's ok to wear pajamas to class.
    • Pets are welcome to join in. Especially cats.
  3. I plan on turning on zoom at 9:30 but not starting class until 9:45. Please feel free to come early and hang out. Some days I might still be getting ready for class. Some days I might play some music (which you can mute if you don't like). Other days I'll be available to chat. Most days class will end around 10:45, but I'll keep zoom open until around 11:00 in case people have questions, want to talk, etc.
  4. I strongly encourage you to take handwritten notes. The physical component of taking notes helps to keep you engaged. And taking handwritten notes requires you to do some on-the-fly synthesis and prioritization, deepening your understanding.
  5. During class there will frequently be times where you will work in small groups on problems. Figuring out the best way to do this on Zoom might take some trial and error.

Homework and Exams

  1. There will be a homework assignment due almost every Friday. It is essential that you do these assignments, as this is how one learns math, and also this is most of what your evaluation will be based on.
  2. As discussed in this video there will be two parts to almost every homework assignment:
    1. Problems to be submitted on Edfinity
    2. Problems to be submitted on "paper" (a scanned pdf) on google classroom
  3. Edfinity is an online homework system. I use this system even when the world is not in a global pandemic. There are three reasons why I use Edfinity:
    1. You get instant feedback while doing the work, so you can learn right away from your mistakes. You can submit solutions many times until you get everything correct.
    2. Some problems are randomized so that you will all get slightly different versions of the questions. This means that collaborating with other students will be maximally effective, since you'll have to share solution methods and not just the final answer.
    3. Since the problems are automatically marked, I can spend more time helping you and won't have to spend as much time grading.
  4. If you need extra time for one or two of the homework assignments, it's not a big deal. But be mindful to not fall farther behind every week.
  5. I do not expect all of the homework assignments to be easy; I don't expect you to be able to sit down and do them easily the first time. Don't let yourself get frustrated. I strongly suggest working with others and seeking help if you need it.
  6. You are strongly encouraged to work together on homework. You can also consult me, class tutors, other faculty, friends, and family. However, the homework you hand in should represent your own understanding.
  7. As I plan on sending out homework assignments and other information via email/google classroom, it is important that you check your email/classroom regularly.
  8. I anticipate that there will be two exams one around week six and the other during the last week of the term. These exams will be open-notes and (essentially) untimed.
  9. You will want to have at your disposal a scientific calculator or phone/tablet app. I strongly suggest an actual calculator. You do not need a graphing calculator for this course (or, in my opinion, ever).

Help Sessions

The Teaching Assistants and I will have a handful of help sessions every week. You are warmly invited and encouraged to attend these sessions. Help sessions are relaxed, informal, and hopefully fun. Things that happen at help sessions:

  1. The TAs and/or I am around to offer help on the homework.
  2. Some students do most of the homework while at a help session. They work through problems alone or with others, and find it comforting to know that help is immediately at hand if needed.
  3. Others do the problems at home and come to the help session with specific questions.
  4. We can experiment with breakout rooms for folks who want to work together in small groups during the help session.
  5. Help sessions are also a chance to ask general questions about the course. Conversations also sometimes wander into other areas: politics, the state of the world, what's for dinner, what classes are offered next term, and so on.
  6. Help sessions are a great way to meet other students in the class.

Everyone is welcome at help sessions! Attending these sessions help students do well in the class and get as much out of it as possible.

You should also feel free to reach out to me and the Teaching Assistants with questions. If you're stuck on a problem, it might help to take a photo of what you've done so far and include it in an email to us. We might be able to help you with a short email, or we could set up a time to meet on zoom

Diversity and Inclusion

It is my intent that students from all backgrounds and perspectives be well served by this course, that students' learning needs be addressed both in and out of class, and that the diversity that students bring to this class be viewed as a resource, strength, and benefit. It is my intent to present materials and activities that are respectful of diversity: gender, sexuality, disability, age, religion, socioeconomic status, ethnicity, race, and culture.

Learning about diverse perspectives and identities is an ongoing process. I am always looking to learn more about power and privilege and the harmful effects of racism, sexism, homophobia, classism, and other forms of discrimination and oppression. Your suggestions are encouraged and appreciated. Please let me know ways to improve the effectiveness of the course for you personally, or for other students or student groups. If something was said or done in class (by anyone, including me) that made you feel uncomfortable, please talk to me about it. You can also reach out to Provost Ken Hill, or Associate Deans Bonnie Tai or Jamie McKown.

Evaluation

Roughly...

  • Weekly Homework Assignments: 70 percent.
  • Midterm: 15 percent.
  • Final: 15 percent.

I do not have any quota of A's, B's, etc. This is an unusual time. I'd strongly consider taking this class without letter grades. Perhaps for some of you not having letter grades will reduce anxiety. I'm happy to talk through options if anyone wants.

Textbook

We will be using the following textbook for Calculus I in winter 2021 and Calculus II in spring 2021: 5th edition, Hughes-Hallett et al, Calculus. Single variable. Paperback: ISBN-10: 0470089156. ISBN-13: 978-0470089156 Hardcover: ISBN-10: 0470131594. ISBN-13: 978-0470131596.

There are many different editions of this book. When you buy it, be sure you are getting the correct one. The best way to do this is to search for it via the ISBN. The ISBN is unique for each version of the book. E.g., the 3rd and 4th version of the same book will have different ISBNs.

This book costs as much as $120 dollars if you buy it new. However, you can get a used copy of the book for around $5 online plus a few dollars for shipping. Yup. For under $10 you can get your very own copy of an excellent calculus textbook.

Why is the book so inexpensive? The edition of the book that we're using is not the newest edition. As a result, there are many, many used copies available online. Most colleges have already switched editions, but I thought it didn't make sense to, since so far as I can tell there is no significant difference between the different editions, other than switching around the exercises. (The only reason publishers come out with new editions of calculus textbooks is to undercut the used book market. Calculus itself hasn't changed in over a century.)

To find the book online go to amazon.com or abe.com (or your favorite used bookseller) and search using one of the ISBNs above.
