Before I tell you about how you might use a blog in the classroom, let’s look at one of the easiest ways you can put your toe into the warm blog waters. There are several blog platforms available. Some require a web hosting plan, but two of the most popular do not and are free.
My personal favorite is WordPress. It offers a free beginners website that allows you to try out many of its features. If you desire more features, you can purchase a web hosting plan and install WordPress on that host. On most hosting plans, installing WordPress software is free . A WordPress installation on your own hosting service adds flexibility and allows you to use a wide array of tools to customize how your blog looks.
One of my favorite activities in class involves the wireless carrier Verizon. The data for this activity comes from several years of annual reports published on the Verizon website. I have used this data in several contexts. In this post, I’ll demonstrate three of these activities. The first activity I use in the context of average rates of change. This activity is appropriate for a College Algebra or Calculus class. The second activity uses the same data in the context of marginal revenue. Finally, I’ll examine a point of inflection on the revenue at Verizon as a function of the number of wireless connections.
I originally planned this post to be about the Verizon Activity I talked about at MAA Mathfest. However, I decided to write about an activity I came up with on my way back from the Mathfest.
I guess all of you are also finishing off your first week or two of classes. Over the years I have spent less and less time going over the course policies on the first day. For me, the first day used to be an anomaly. I talked all of the hour and fifteen minutes and they sat. None of the subsequent classes would be like this. Yet this first day often turns students off and gives them the impression that my class is a one way communication channel. Many students may drop the class purely on the basis of that first day.
Instead of spending the entire class on the syllabus, I do fifteen minutes on how their grade is determined and then move on to an activity. They take a syllabus quiz over everything and that seems to be a better way to get them to review what they will be held responsible for. For my college algebra class this semester, this activity had a secret motive. I decided to add to the group activities I do in class and make the projects in the class a collaborative effort. To make these groups effective, I need to get a feel for the students and how they work together. I wanted the activity to give me a feel for their personality…leader or follower.

The first two projects in the College Costs series focus on linear and quadratic models. In this post, we’ll look at exponential models of the college cost data and use it to answer the question: If you spend your first two years of college in a two-year college instead of a four-year college, how much would you save? We will demonstrate the process by modeling the national costs y as a function of the number of years after 2000 t with
y = Pert
This allows us to incorporate exponential function into the College Algebra curriculum as well as logarithms.
No discussion of passive learning can begin without a reference to Ben Stein’s portrayal of an economic teacher in “Ferris Bueller’s Day Off” in 1986.
I think most of us could argue quite persuasively that there is no learning going on in this classroom. Although the teacher attempts to interact with the students with the infamous “Anyone, anyone?” question, there is no response from his audience. One might note that he is facing the class and attempting to gauge the student’s understanding of voodoo economics. Is he practicing active retrieval to help his students consolidate the information in memory? Continue reading Passive and Active Activities in the Flipped Classroom (Part 1)→
