PRINCIPLES OF HYDROGEOLOGY
Dear Hydro student of the
You found this page because you
are interested in being one of the first students
ever to take an upper-level hybrid online Earth Science
course at NEIU. "Hybrid Hydro" is offered in Fall
Each week you will complete
readings, problem-solving tasks, and practice quizzes
online, at your own pace. Then you'll come to
campus and work hands-on with lab materials, maps,
and computer modeling. Some labs will be
individual, and some will be completed in teams.
Most labs can be scheduled at your (or your team's)
The result? Learning
that combines the advantages of an online course
(flexibility, convenience, self-paced learning) with
hands-on engagement (practical experience, kinesthetic
The course framework and
materials are still in development, but that's the
Have a time conflict with another
course? No problem. Since lab sessions will
be individually scheduled, you can work on them at your
own convenience. Ask Dr. Voglesonger for help
registering (K-Voglesonger [at] neiu.edu).
I look forward to
working with you to discover exciting new ways to master
the concepts and applications of hydrogeology. Questions? Let me know.

What you see below is very much
under construction. Several people have asked for
an idea of what we will be doing, so I developed this as
a means of giving them the general outline. I'm adding and
editing and rearranging this list on a nearly daily
basis, so you can either watch it develop or ignore it
until the semester begins.
