Introduction

The DAP lets you quickly set up an on-line form to allow students to enter observations. You can use it to have students in class enter observations and all download the aggregated data. In this way a whole room can enter measurements much more quickly than if they all had to enter them using one machine. Even better, we use the system to allow us to aggregate data across multiple lab sections. By having all 30 sections contribute measurements, we can build a dataset with n=600 in a week. This gives students a much more robust dataset to analyze where even phenomena with a small effect size can be studied. Furthermore, it provides a rationale for using technology: we let them analyze those 600 data points in any way they want.
