A Course is Born
• Summer of 2005
• On the Cutting Edge – Professional Development for Geoscience Faculty Workshop: Teaching Hydrogeology in the 21st Century
• Need for people teaching hydrogeology to learn field tools and techniques

Teaching Issues
The Good, The Bad, and the Impermeable Layer

5 Components
1.To think
2.To be professional
3.To communicate
4.To be fearless (does not include stupid)
5.To achieve the Zen of fieldwork

The Zen of Fieldwork
• Rarely see fist fights in class, not true in field courses
• Discuss this with class• Instead of fights, people will
actively monitor their distance from Zen (generally walk around repeating “Must be Zen” when equipment or students not cooperating)
![Page 7: Teaching Field Methods in Hydrogeology Todd Halihan Shemin Ge F. Ed Harvey (adapted from 2007 GSA Short Course)](https://reader035.vdocuments.mx/reader035/viewer/2022062407/56649ea85503460f94bab3c2/html5/thumbnails/7.jpg)
Your background
• Math phobic? • 5 senses – data input
– Sight– Hearing– Taste– Touch– Smell
– None of these work for well for ground water problems – need INSTINCTS
![Page 8: Teaching Field Methods in Hydrogeology Todd Halihan Shemin Ge F. Ed Harvey (adapted from 2007 GSA Short Course)](https://reader035.vdocuments.mx/reader035/viewer/2022062407/56649ea85503460f94bab3c2/html5/thumbnails/8.jpg)
Project Course Sites
• http://www.basecamphq.com/
• Project management websites
• Hard to keep people using them
• May be useful for some courses/situations, but students generally just meet somewhere
![Page 9: Teaching Field Methods in Hydrogeology Todd Halihan Shemin Ge F. Ed Harvey (adapted from 2007 GSA Short Course)](https://reader035.vdocuments.mx/reader035/viewer/2022062407/56649ea85503460f94bab3c2/html5/thumbnails/9.jpg)
Round Robin System
• 3 “companies” conducting projects(Encourage company names)
• 1 project manager for each company
• For three weeks, three projects will be conducted by the three companies
• Each project will be written into a letter report detailing results (provide examples)
![Page 10: Teaching Field Methods in Hydrogeology Todd Halihan Shemin Ge F. Ed Harvey (adapted from 2007 GSA Short Course)](https://reader035.vdocuments.mx/reader035/viewer/2022062407/56649ea85503460f94bab3c2/html5/thumbnails/10.jpg)
Importance of Project Manager
• Removes your responsibility for project fuzz – little details that the students can take care of if someone feels responsible
• Gives contact for several students in class to communicate info
• They understand the different issues that occur as manager instead of just student
• Reports are better

Example Round Robin 1
• Project 1: Basin Assessment
• Project 2: Well Rehabilitation
• Project 3: Long term monitoring
• Setup of field site and researching background can be initial projects
• Similar to a Tier 1 investigation
![Page 12: Teaching Field Methods in Hydrogeology Todd Halihan Shemin Ge F. Ed Harvey (adapted from 2007 GSA Short Course)](https://reader035.vdocuments.mx/reader035/viewer/2022062407/56649ea85503460f94bab3c2/html5/thumbnails/12.jpg)

![Page 19: Teaching Field Methods in Hydrogeology Todd Halihan Shemin Ge F. Ed Harvey (adapted from 2007 GSA Short Course)](https://reader035.vdocuments.mx/reader035/viewer/2022062407/56649ea85503460f94bab3c2/html5/thumbnails/19.jpg)
Beware
• Single disgruntled student can wreck project
• Need to manage as quickly as possible
• Set expectations early
• Single biggest problem in field classes
• Cultivate cheerleaders
![Page 20: Teaching Field Methods in Hydrogeology Todd Halihan Shemin Ge F. Ed Harvey (adapted from 2007 GSA Short Course)](https://reader035.vdocuments.mx/reader035/viewer/2022062407/56649ea85503460f94bab3c2/html5/thumbnails/20.jpg)
Include peer evaluation
• Student perform better when the group evaluates their own performance
• Key metrics– % of contribution (to field and to reporting)– Ranking of contribution– Easily see who the group felt performed
and who sat back
![Page 21: Teaching Field Methods in Hydrogeology Todd Halihan Shemin Ge F. Ed Harvey (adapted from 2007 GSA Short Course)](https://reader035.vdocuments.mx/reader035/viewer/2022062407/56649ea85503460f94bab3c2/html5/thumbnails/21.jpg)
