CSTEM 5104 Ratio, Rate, and Proportion
Ratio, Rate, and Proportion is a course designed by Lesley University Center for Mathematics Achievement, which will focus on exploring the role of ratio and proportion in mathematics and the world around us. This course focuses on the development of ratio through the use of scale factors and graphing models; rate in terms of unit rates; and proportion through linear, inverse, and joint proportionality models. The course will develop the concepts using multiple representations and through problem solving. Individual and group problem solving tasks will permit students to observe, analyze, and contrast various representations and discuss the advantage of each. Each student will keep a learning log noting insights into his or her own understanding of ratio, rate, and proportions and the various ways in which they might be represented. A portfolio will also be developed illustrating what each student learned.
