•
Why teach students high precision GNSS tools?
•
If you want to measure small changes (a few cm or
less), you have to use high precision instruments.
Applications include:
–
Tectonics (intra-plate and plate boundary)
–
Volcanic Activity
–
Geomorphic Change Detection
–
Hydrologic Change
–
Tracking or mapping other fine-scale objects

Curriculum is constructed around three goals:
–
Students can
design and conduct
a GNSS survey to address
a geologic research question.
–
Students can
justify when and why different techniques
are appropriate
in different situations.
–
Students can
apply the findings
of GNSS surveys to
societal issues

We accomplish these in three, field-based units

OTHER LOGISTICS
•
Meet hotel foyer 7:40 am
•
Tomorrow is on campus but we will be
outside up to several hours total so bring:
–

TOMORROW
Explore the benefits and challenges of integrating high-precision GNSS tools in field courses for geoscience students. Discover how students can develop valuable skills, apply GNSS surveys to societal issues, and tackle geologic research questions. Uncover strategies to overcome barriers and motivate students to learn GNSS techniques for precise positioning.

HIGH PRECISION GNSS INTHE GEOSCIENCES Why teach students high precision GNSS tools? If you want to measure small changes (a few cm or less), you have to use high precision instruments.

BENEFITSTO INTEGRATING GNSS IN FIELD COURSES What are your experiences? Students developing desirable/saleable skills Provide differing approaches to similar questions Integrate quantitative skills into traditionally qualitative learning environments Broaden the types of data incorporated into field observations
BARRIERSTO INTEGRATING GNSS IN FIELD COURSES What are your experiences? Traditional vs. Modern Tools How to keep all students engaged? Technology is expensive We may not be experts in the technology yet
