Increasing Student Engagement in Online Education with Virtual Field and
Lab Experiences
Abstract
In online education, student-to-student interaction can be an important
component to encouraging independent thinking and achieving learning
objectives. The course development team for “Minerals and Human
Health” will share experiences in designing and implementing a virtual
laboratory and collaborative projects for this online course. The first
of its kind to be offered fully online, “Minerals and Human Health”
encompasses the study of interactions between people and earth’s mineral
resources, and how these interactions are influenced by a variety of
natural, human health-related, economic, cultural and political factors.
The virtual laboratory takes students on a virtual field trip to
abandoned gold mines in the Mojave Desert, where students are able to
observe images of samples provided from an electron microscope that the
development team extracted for analysis. Using advanced recording
techniques, stabilized body cameras, aerial drone footage, macro
videography and wireless microphones, the team created a simulated field
geologist experience, including footage of having narrowly escaped a
massive desert dust storm. The virtual laboratory continues with a
sequence of interactive videos where students are introduced to
surveying and extraction from the field, lab equipment, and methods for
analyzing and identifying mineral particles in dust samples. After
learning principle concepts, students prepare an home-project called
“The Air we Breathe”. In this collaborative project, students interact
with each other via online discussion forums and video conferencing in
order to collect dust particles for lab analysis. Students deliver the
samples for study under optical and electron microscopes to the
instructor, who distributes the results back to the students. Students
then present their interpretation of the findings. Students are
astonished to discover the air that they breathe every day includes
hazards such as PM0.5-0.2 that are classified as carcinogenic materials.
Initial student feedback has been collected throughout this newly
developed course to identify areas that were most impactful and that
could be improved for future iterations. Join us as we share our lessons
learned while creating this extraordinary online learning experience.
