Reflection: Student Ownership Speed Dating with Logarithms - Section 2: Application: Speed Dating with Log and Exponential Equations


This type of lesson is really quite difficult to run and I it took me awhile to adjust to the fact that we may not do that many problems in the hour. During those first 10 minutes when students are becoming experts on their problem it is hectic! We really need to rely on our strong students to step up and help out… which can be stressful. Students are feeling the pressure to really understand their problem and if they get stuck they need to have somewhere to turn. I begin by making sure I am available during this time to guide students who are stuck. I also start to point out students who have successfully solved their problem. “Asha is done, maybe you can ask her for help.” Or “Hey Mark, can you help Dania on that same step that I just helped you on.” I also find that blanket statements made to whole class can be helpful. “Isolate the base and exponent, you know how to do this using algebra, then use your favorite log method from there.” Sometimes my students need 15 or maybe even 20 minutes to become experts on the problem. I try not to stress. Everyone is typically busy doing something, either helping another student or learning how to solve the problem. So I think it’s ok if it takes longer. Once students understand the method the speed dating part of the activity will go quickly. If we only get through 2 or 3 rotations, I still consider it a success. It really just varies by each class and students’ current ability to solve the problem presented to them.
