This site contains a pedagogical module containing two Questions of the Day and a “write-pair-share activity” involving Florida's population growth.
The task of a student completing this project is to construct a mathematical model and, as a result, recognize the differences and similarities between linear growth and exponential growth.
Type of Material:
Homework or in class group work.
Works an every browser.
Identify Major Learning Goals:
The major learning goal of this project is to investigate through data the difference between linear and exponential growth.
Target Student Population:
College Algebra and Liberal Arts Mathematics students.
Prerequisite Knowledge or Skills:
Basic understanding of linear and exponential curves.
Evaluation and Observation
This activity provides the instructor and students with everything they need in order to complete this activity on linear and exponential growth. In particular, it is based on data charts located at the U.S. Census Bureau website. The two data sets provided are clearly but not perfectly linear and exponential. Once completed, the project helps students clearly understand the differences (and similarities) between linear and exponential growth.
Potential Effectiveness as a Teaching Tool
The activities in this learning object will act as a great example that will ground the abstract concepts of linear and exponential models. The learning goals are clearly presented. Students will work in groups or partnerships and help each other to express the mathematical concepts. The site also contains teaching notes and tips and recommends assessment.
Ease of Use for Both Students and Faculty
This activity is exceptionally laid out. Students or their instructor can just open up the site and read through the simply explained instructions. The author did a great job in ensuring the ease of use.
