Observing Student Connections

 Now let's look at how a class made connections among mathematical topics, between representations, and to reasoning and proof as they discussed an exponential function. Look at the students' work and read their statements. Notice the teacher's efforts to help students make use of connections, when applicable. As an introduction to working with exponential functions, Mr. Costa gave his Algebra II class an open-ended assignment. Over the course of several days, students were encouraged to use a variety of methods, including their graphing calculators, to make many discoveries and observations about several equations, in particular, y = 2x - x - 3. Students were also asked to create individual written reports. Let's take a look at some excerpts from students' papers and hear some of their responses to this assignment.
