To better prepare students for their future, it is important that we continually integrate new technologies and methodologies into our classrooms both with respect to instrumentation as well as data processing and sharing. New tools, such as Google Apps, have provided many new ways to engage and assess students while incorporating practices we as educators are already accustom to. In this presentation, we will specifically focus on our experience with the Google Drive app and its integration into to our General Chemistry sequence at the University of Indianapolis. We will share our experiences in redesigning our labs so as to collect meaningful data from the students regarding their experiments and how we were then able to give the students a richer educational experience than we were previously able to do using that data. Additionally, we will show how we are utilizing capabilities such as form creation so as to more effectively assess our teaching effectiveness during the progression of the semester and our observed impact on performing prelab lectures on YouTube and the impacts on student learning.

A popular technique for demonstrating the kinetics of nuclear decay is to use dice as a manipulative. Students can see the decay process and create graphs that allow them to better appreciate how first order kinetics occurs. A variation on this technique involves using dice with different numbers of sides to examine how probability affects rate constant and half-life. Here these ideas are expanded on in an effort to expose students to the nature of complex kinetic processes including equilibrium and a radioactive decay series. It also gives them an opportunity to conduct some basic computer modeling. Dice of various numbers of sides are used to collect data on a variety of A ↔ B equilibria and a simulated 5 step nuclear decay series. The results are modeled using a spreadsheet program and the fundamental rate laws of first order decay. An additional component to this experiment is its opportunity to utilize online data sharing as a way to improve statistical averaging without having each student repeat the simulation multiple times. This experiment is appropriate for students in a second semester general chemistry laboratory course.
