Interpreting Data & Science• Identifying change, Cycles? Periodicity? what could it mean? • When do we expect the next one?•How does this movement relate to plates? everywhere? How would we test our hypotheses?

Integrating data:• How does this movement relate to plate movement you see on the map? How does it relate to where earthquakes occur…where volcanoes occur? What other kind of data might we need to gather?

Quantitative skills• Rate and direction of movement• Use of spreadsheets, graphs, precision versus accuracy, Error, Averaging

Getting students beyond…

… the theoretical and without context …

… to exploring data and making interpretations

What is meant by the term data

• Scientific context Numerical information collected from an

instrument Raw vs processed Observation vs model Images vs digital underpinnings Real-time vs recent vs archived

• Educational context Any information that supports student inquiry

and participation in the scientific method.• Includes: numerical data, plotted data, data

visualizations, and othersReference: Using Data in the Undergraduate Classrooms - Carleton College April 2002

Using data and visualizations to teach

• Explore concepts & relationships with visualization tools: Jules Verne Voyager tools and Google Earth overlays

• Digging deeper: Examine evidence through data products. Data for Educators & GPS time series plots

• Starting at the source: Access & analyze GPS data to investigate trends. GPS data sets

• Putting data sets together: Yellowstone Case Study

• Going beyond GPS: LiDAR, InSAR, Polar activities, and more in the works

Jules Verne Voyager

• Provide on-line, interactive geophysical data visualization tool

• Develop conceptual understandings of relationships among many complex types of data

GPS Stations

Starting with the basics: GPS Time Series Plot

Y-axis:

• North (N/S)

• East (E/W)

• Height (up/down) (sometimes called Vertical)

• In millimeters

X-axis: Date of the measurement In 10ths of year or months

Red data points are rapid position estimates

BEMT & SBCC Times Series Plots

Adding vectors

North

3.1 mm

3.4 mmEast

Interpreting the data

• BEMT = ~7.3 mm/yr to the northwest

• SBCC = ~38 mm/yr to the northwest

Imagine you are on a 3 lane highway, driving in the middle lane…

SBCC

BEMT

SBCC is moving ~5 times more quickly than BEMT … What does this mean?

Using observed data for modeling

Stretching beyond the typical

Multiple classroom settings

Fitting an activity to a large lecture hall (Faculty-in-Residence: Anne Sheehan: University of Colorado)

• Data ‘simplified’ No negative values Scale of all plots the same

• Developed clicker questions to check understanding• Students

Work in teams of 4 Analyze two GPS Time Series Plots (coastline and inland) and

determine velocity vectors Create combined map

Fitting to smaller class: mid-level geophysics course (Teaming with Sarah Titus: Carlton College)

• Additional stations provided• Students do more analysis of the data

From data to TSP to vector





• Putting datasets together: Yellowstone Case Study


Overlaying datasets

Students plot locations of• Hydrothermal Eruptions• Hydrothermal Activity• Areas susceptible to

volcanic gasses• Historic major

earthquakes• Areas with recent

earthquakes• Survey and GPS

stations

Unsolicited Feedback

I used the [Yellowstone] activity for a Year 11 Geography class. We

were discussing how humans interact in areas of volcanic and earthquake activity and measures taken to lessen effects. I came across your lesson and the video around the same time and saw a good fit

since they mention the same issues. I also like to use as many ‘real world’ activities as I can. So, a geologist

doing a field study and getting paid for it fit very well. It showed vocation possibilities and stressed the use of

fieldwork in geography. The kids were engaged from the beginning. … - teacher in Australia





• Putting datasets together: Yellowstone Case Study


GPS, LiDAR, and InSAR! oh my!

Southern CA: GPS and LiDAR

• Downloaded the data • Superimposed onto

Google Earth• Used Google Earth tools

to make analysis & interpretations: offsets on faults, relative lengths of GPS vectors

Workshop evaluationsThe workshop was well organize and

The objectives of the workshop were stated and fulfilled

I found the relative time devoted to the various workshop activities to be

appropriate

The workshop included a variety of effective instructional strategies

As a result of this workshop, I feel my preparedness to instruct about plate tectonics and seismology has

increased

As a result of this workshop, I will definitely implement some additional and plate tectonic science content to

my teaching.

This workshop provided me with new and challenging content for using

GPS data that was not overwhelming.

Overall this workshop was a valuable use of my time

I can apply the information/skills learned in this workshop to my

teaching with limited modifications

Workshop feedback

“So well organized and executed - these 3 folks made an Awesome team” –NSTA teacher

“… Actually getting to use and do things that I can use in my classroom. … I also enjoyed the teaching tips.” –NM teacher

“Some of the activities were a bit confusing since there wasn’t enough time to explain all aspects. At first I thought the monument was a bit elementary, and then I saw how sophisticated it could be.” – NM teacher

“Some a bit too complicated for my 6th graders, I'll have to adapt some of it.” – NSTA teacher

“… I've been to a variety of workshops and few of them would be better than this one. The activities were obviously well vetted and organized in a logical fashion. Thanks!” – Nebraska teacher “Thank

you so much for bringing your expertise and enthusiasm to the learning at University of Portland.” –TOTLE teacher

Continual Improvement

• More sign-posting (pre, during, after) during workshops

• College Faculty want lots of examples and ideas for creating activities but don't necessarily want to work through the complete activity

• Secondary Ed teachers EXPECT activities to be worked through as part of the workshop

• More follow-up with teachers, faculty, etc.

• Longer duration professional development workshops (~5 days)

• Scientists want feedback on how they did (did they have an impact?)

Guidelines for Data and Data Access

• Single interface, easy to figure out, data products grouped into themes.

• Multiple-pathways to access the data Visual display of GPS station locations Quick previews of time series plots of the data Capability to download multiple sets of data at one time

• Online visualizations/animations with legends online manipulation of variables downloaded data

• Data in Excel readable formats and managable sizes (<100 mb)

• Data with column headings & metadata information

• Interesting data illustrating a geo-tectonic process, the ‘story’ and the ‘so-what’ (Interpretations and relevance)

Improving data tools & interfaces for faculty often improves access for researchers in a variety fields …

For the Future

• PBO, Facility, E&O keeping in touch with each other

• Involving more scientists in workshops “More Bob [King] - scientific

explanations of the data”

• JVV, IDV, Google Maps

• Data for Educators Continued integration w/ Facility

& PBO Improving ways to indicate

connection between activities and GPS Stations
