WEBINAR FORMAT
• Presentation (~35 minutes)– Geodesy & its applications– GETSI Project– Existing geodesy teaching resources
• Discussion (~35 minutes)– Most valuable future module topics to address– Types of curricular items of greatest value– Other geodesy teaching resources you know of– Questions
GEODESY IS…
5
…the science of accurately measuring the Earth’s size, shape, orientation, mass distribution and the variations of these with time. Traditional geodesy:
Precise positioning of points on the surface of the Earth Modern geodesy:A toolbox of techniques to better measure the Earth

UNPACKING THE GEODESY TOOLBOX
• GPS (Global Positioning System)• InSAR (Interferometric
synthetic aperture radar)• LiDAR (Light detecting and
ranging)• Strain meters, tiltmeters, creep
meters• Gravity measurements• Sea level altimetry

WHY GEODESY FOR STUDENTS?
• Topics align well with Earth Science and Climate Literacy Principles
• Real world applications are shown to increase interest and learning
• Data analysis can increase critical thinking skills and quantitative skills
• Measurement are on a human timescale• Earth science majors are often not learning
about these critical research techniques
GETSI PROJECT OVERVIEWMission: Develop and disseminate teaching and learning materials that feature geodesy data applied to critical societal issues such as climate change, water resource management, and natural hazards• Funded by NSF’s Transforming Undergraduate
Education in STEM Type I grant• Collaborators – UNAVCO, Mt San Antonio College,
and Indiana University in partnership with SERC and NAGT.
• Will develop four modules (~2 weeks each)– Two Intro-level – Two Majors-level
GETSI PROJECT MODULES
• Module development and assessment following model of SERC’s InTeGrate Project
• Year 1 module topics– Intro Ice mass and sea level change
Becca Walker (co-PI) & Leigh Stearns (co-author)– Majors Active tectonics and hazards using InSAR
and LiDAR dataBruce Douglas (co-PI) & Gareth Funning (co-author)
• Year 2 – tell us what you would like to see
GETSI PROJECT INVOLVEMENT (WITH STIPEND)• Two module co-authors in Year 2 ($7500; over ~15
months)• Five beta-testers for each module ($200-500
depending on involvement level)• Technical experts for some modules ($200-500
depending on involvement level)
Everyone from this webinar will receive announcements when we solicit for the above but contact me ([email protected]) if you have particular interests.

DISCUSSION FORMAT
• I will pose some questions• Start by raising your hand to speak or typing in
Chat• Use *6 to unmute yourself and talk (then
mute again)
If needed, I may call on people to make sure a variety are heard from.
DISCUSSION
What topics would you like to see modules address and why?• Hazards
– Volcanic, earthquakes, landslides…• Climate change
– Ice mass changes, ice velocity, sea level…• Water resources
– Ground water mass, surface water…
What level? What course? Particular data types?
DISCUSSION
What types of teaching resources do you adapt/adopt most?• Instructor notes/technical background info• “Prepared” data sets for students use• Accessible data portals• Lab/class activities• Homework• Presentations/animations• Assessments (rubrics, criteria)• Other?
Helpful formats?
Could you see doing full two weeks material?
Course or level difference?
DISCUSSION
Do you already teach about or using geodesy data?
Other resources we should
know about?
Pitfalls?Successes?
DISCUSSION
Comments/suggestions?
Questions?– About GETSI?– About existing resources?
