Research Validated Distance Learning Labs for Introductory Physics Using IOLab

Abstract

The IOLab is a versatile, relatively inexpensive data acquisition device developed by Mats Selen and his colleagues at University of Illinois. It is self-contained in a cart that can roll on its own wheels, while an optical encoder measures motion quantities. It also contains sensors to measure a variety of other physical quantities like force, temperature, light intensity, sound intensity and current and voltage. With a current cost of around $100, students can purchase their own individual device (like a clicker), and can—in theory—use it to do hands-on laboratory, pre-lecture (flipped classroom) and homework activities at home. We report on the preliminary results of a project to develop distance-learning (DL) laboratories using the IOLab. We have developed RealTime Physics-like mechanics labs based on the IOLab, tested them in supervised laboratory classrooms and distance learning environments at Portland State University and Chemeketa Community College. We will present details of the IOLab, examples of the IOLab activities, and preliminary research on student learning—using the FMCE—and attitudes.
