**Calculus 2022-2023**

(updated June 2022)

The Mathematics Department is continuing to develop and refine our Calculus courses, Math 1300, 1400, 1410 and 2400, building on the changes instituted in Fall 2020. A summary of the changes is given below. Beginning in Fall 2021, we modified the way you will register for these Calculus courses as we plan to return to on-campus, in-person teaching.

**Registering for Calculus classes**

One of the structural changes instituted in Fall 2020 was the replacement of high-stakes midterm exams with more frequent, lower-stakes “Friday quizzes” together with opportunities for “makeup” or “re-do” quizzes to improve your grade. Our experience with this indicated that learning outcomes improved with this system of assessment, so we have adjusted the course registration for Calculus so that you select your quiz times during registration.

As a result, you will need to register for **three** components rather than two: A lecture time, a recitation time, and a lab time for quizzes.

Your lecture and recitation sections must be linked (and this is indicated in Courses at Penn). For example, if you register for the MATH 1410-002 lecture, which meets on Wednesdays from 12:00-1:30, then you must also register for either MATH 1410-203 or MATH 1410-204 for your recitation, which meet on Mondays from 12-1:30.

Additionally, you must register for a section of MATH 0140 for your quiz time. All of these meet on Fridays, and it doesn’t matter which one you choose.

This means that an example of a complete MATH 1410 registration is

MATH 1410-002 together with MATH 1410-204 and MATH 0140-103

Registration for MATH 1300, 1400 and 2400 will follow a similar pattern. The quiz sections for MATH 1300 are numbered MATH 0030, the quiz sections for MATH 1400 are numbered MATH 0040 and the quiz sections for MATH 2400 are numbered MATH 0240.

Thus, an example of a complete MATH 1300 registration is

MATH 1300-004 together with MATH 1300-213 and MATH 0030-102

An example of a complete MATH 1400 registration is

MATH 1400-007 together with MATH 1400-213 and MATH 0040-104

An example of a complete MATH 2400 registration is

MATH 2400-005 together with MATH 2400-209 and MATH 0240-101

The surest way to make sure that the three components you have chosen are a valid set of choices is to begin with the lecture section in Courses at Penn. For instance, if you search for MATH 2400 and select lecture section MATH 2400-004 as shown here:

then information will be displayed listing all valid choices for this lecture section:

You can then sign up for the lab (Math 0240 in the case of Math 2400) by searching for it just as you did for Math 2400.

**What is a summary of the major changes instituted last year?**

In brief, they are:

1. **Coordinated sections. **All sections of a course have the same pace, structure, and lectures, independent of who is the instructor. This gives students a more uniform experience, less dependent on getting a particular prof.

2. **Asynchronous video lectures.** All lectures are delivered via short videos. This should help you manage your time by allowing you to watch lectures whenever you wish.

3. **Active learning.** The normal lecture time will feature active problem-solving or other activities, dependent on the instructor. This should give you a chance to interact with your peers and your instructor more.

4. **No midterms.** Midterms are replaced with quizzes at the rate of three per month. There will still be a final exam, but it will count for less that it has in the past. This lowers midterms-week anxiety.

5. **No required textbook.** We have developed our own video-based “texts” and generated additional materials to help serve as resources. This savea you an unpleasant expense.

6. **Rescheduled recitations.** Since you are spending time watching lectures online, class will not meet as often. In particular, recitations with your TA will take place within the lecture period. This means no more 8:00am recitations.

**What are the advantages of this new structure?**

· *Less stress; more fairness.* With more low-stakes quizzes and periodic re-takes, your entire grade doesn’t depend on a single high-stakes exam.

· *Better time management.* With no 8am recitations and lectures viewed when you want, you’ll have more flexibility in how your week goes. The weekly structure of the course will motivate you to stay current on the material.

· *Less variance between sections*. Since everyone views the same set of lectures, you don’t have to worry as much about which section you get into. If your friend is in a different section, you can still study together.

· *Less expense*. There is no expensive required textbook.

· *Modern curriculum*. Since we’re not bound to a given text (typically produced for mass-appeal), we can tailor our instruction to what is best for Penn students. We’ve been working hard to modernize the curriculum to show you examples and applications of relevance to you and your fields of study.

**How can I prepare?** If you’ve been away from math for a while (i.e., you didn’t take a precalculus or calculus course during your senior year of high school) it would be a good idea to review material from the last course you took – brush up on those derivative formulas and trig identities! But the most important thing is to be prepared to hit the ground running in one of these rigorous, fast-paced courses. It will be important for you to keep up with the flow, and to devote some time to learning mathematical concepts and/or practicing techniques nearly every day.

**I'm an incoming student. Which course should I take? **The Mathematics Diagnostic test that you are taking online this summer will give reasonable guidance as to which course you should take (among 1300, 1400 and 1410) this Fall. But generally, if you had AB Calculus in high school you should begin with Math 1400, if you took BC calculus and got a 5 on the exam (if you took it) and *very* confident in your ability then take 114. Work with your advisor to select the appropriate course, and if there’s real doubt, contact the Math Department.

**How will this work with my disability? **In many ways, the new format should provide enhanced opportunities for students with disabilities to take in the lectures at their own pace and repeat sections if necessary. As usual, instructors in the courses will follow the recommendations of the Student Disabilities Office regarding appropriate accommodations for the weekly quizzes and the final exam.
