Class Journal

We’ll use this page to keep track of what has happened each day in class. It won’t contain any of the nitty-gritty details, but will instead serve to summarize what has transpired each day.

Week 1

  • Monday, August 27: Our first day! Dana attempted to learn names and then spent some time discussing the syllabus and course expectations. With the remaining time, students began working in groups on Are You Ready for Calculus? (PDF). While the students were working, Dana walked around and personally greeting students.
  • Wednesday, August 29: After Dana attempted to learn names again, the students continued working on Are You Ready for Calculus? (PDF). During this time, Dana wandered the room answering questions and gathered a list of problems that students seemed to be struggling with. For the last 15 minutes of class, Dana presented some of the problems that were causing the most issues.
  • Thursday, August 30: Class started with students working in small groups on the second half of Are You Ready for Calculus? (PDF). During the last 15-20 minutes, a few students volunteered to present problems, and we finished class by discussing the work that the volunteers presented. Yay, our first day of student presentations! I was impressed.
  • Friday, August 31: Dana spent nearly the entire class session lecturing on the first half of Chapter 1 of the course packet.

Week 2

  • Monday, September 3: Labor Day, no class!
  • Wednesday, September 5: We finished up the rest of Chapter 1.

  • Friday, October 12: Students took Exam 2.

Week 8

  • Monday, October 15: Since we had an exam on Friday last week, we didn’t need to discuss any homework problems. Instead we dove right into Section 4.1: L’Hospital’s rule, which is a tool for evaluating limits involving certain indeterminate forms.
  • Wednesday, October 17: The first half of class was spent discussing a few homework problems involving L’Hospital’s Rule. Then we blasted through content from Sections 2.9, 2.10, 2.11, and the first half of 4.2. Some of the topics discussed included: increasing/decreasing, contant, critical numbers, First Derivative Test, concavity, and Second Derivative Test.

All of this came from Section 5.3: The fundamental theorem (PDF).
