Meeting Room:

Pre-meeting Sharing Space
Please introduce yourself to your team members. Give a brief description of your role in facilitating the use of data in education. You can also post links, files, or images.

To add text, files, or images to this page, click the "Show Editing Controls" link in the upper right of this window, then click "Edit this page." Click the Editing Help link for details. Note that the infrastructure of these editable web pages are still under development. As possible, avoid simultaneous editors.

Session 1 - Thursday Morning
Meet your team members. Learn about the data, tools, and expertise represented on your team. Review DataSheet(s) and explore data and tools.
Team members meet each other and share their experiences and viewpoints on using data in education. Review and discuss DataSheet(s) begun by the data representative(s) for your team. Explore datasets and tools and consider how the expertise on the team can complement them. If you haven't already done so, narrow down the range of datasets the team is considering using to a manageable number.

Here's a test of the rollover technique for displaying multiple images:

A list apart (a really great website)

Perceived to dos, in no particular order:

Identify comarison scenes:

already in EO
Rapidfire.sci.gsfc.nasa.gov (twice daily passes of locations)
UNEP, One planet Many People sets (Landsat)

Identify Goals:

Offer Pictures of Change over Time
In an engaging and browsable manner
So folks can admire easily observable change
RGB
tied to some text explanation
and we offer ideas for how they might take it further for some analysis

Audience:
Just across the chasm on a bell curve
Informal (so folks go there voluntarily)
Interested in Earth, environment,
Un

Topics:
glacial retreat
flooding
reservoirs/lakes
snow cover
irrigation
deforestation
urbanization
volcanoes
aquatic plants
fires and burn scars
seasonable variabilty
dust
aquaculture
mining
suspended sediment
phytoplankton bloom
tsunami
hurricanes
beach change
desertification
degradation of wetlands

Problems:

Lossy data formats

corrections for atmospheric

Analysis we'll encourage:

Measure area of change

Calculate rate of change

Go to image databases and find out how it looks now

Session 2 - Thursday Afternoon
Brainstorm data-use storylines
Brainstorm a set of possible storylines for valid investigations of the dataset(s) you have selected. Come up with at least one compelling scenario that will give users a reason to work through the technological steps necessary to perform an analysis of the data.

The Activity Outline Guide (Microsoft Word 42kB Apr9 08) provides an outline for the minimum information needed for the team's activity outline.

Add Session 2 Notes here:

Exploring functionality in this session
Looked at stack in ImageJ
Compared with rollover test - These are essentially the same

Additional items that should be included on every image:
Dates
Scale - Consider if this should be graphic (a 1 km bar)
or descriptive (Bus, Stadium, City, small state)

Sessions 3 and 4 - Friday Morning
Select a data-use scenario and perform a proof-of-concept check
Use the complementary expertise on the team to check that the task you are envisioning can actually be completed in an educational setting. Identify a target grade level for the activity and choose a working title.

Please limit the scope of the activity to tasks that can be accomplished by accessing existing data and tools. Discuss and agree upon the content limits of the activity as well. Consider that the major goal of these activities is to develop user familiarity with the data and tools.

EET Chapter Outline
Title: Exploring Change Over Time
Dataset: Earth Observatory Change Over Time Collection
Tool(s): HTML, Cascading Style Sheets and/or ImageJ

Explore Change over time in collection of EO images
Stack from a montage technique
Find an image of a place that you could expect to find some change.
Go to image collections (MODIS) to find a complementary image.

Sessions 5 and 6 - Friday Afternoon
Develop your case study storyline and outline the procedures for data access and analysis Case Study Development
Record ideas, bullet points, or actual text that will become part of the case study to introduce users to the issues and concepts of the activity. Gather links for appropriate images, diagrams, and background text.
Data Access and Analysis Procedures
Record the name and URL of all datasets and access/analysis software tools to be used. List the major tasks users will complete, then perform a deliberate walk-through of each task to capture the full sequence of procedures. Give special attention to the most difficult or least intuitive steps, and note points in the sequence where additional information will be helpful.

Add Session 5 and 6 Notes here:

Session 7 - Saturday Morning
Enhance your step-by-step procedures by adding "About" sections that provide extra information; List several ideas for "Going Further" with the data or tools
Fill in any gaps in your activity outline and add sections that can help users make meaning of the data. Suggest several ideas for the "Going Further" section that challenge users to work with the data and/or tools in other investigations. These suggestions provide launching points for scientific inquiry which is facilitated by the skills learned in the activity.

Session 8 - Final Team Breakout
Finalize your Activity outline and DataSheet, Generate PowerPoint slides for the report out session, Upload all resources to this page
Create a 2- or 3-slide ppt file for the report out session.

Slide 1: Team name, names of team members, and a brief phrase to describe each individual's contribution

Slide 2: Working title for your activity, names of dataset(s) and tool(s) utilized

Slide 3: Your choice of something to illustrate your team's vision of the completed activity

Attach the file plus any other documents produced by the team to this page. Include final versions of the team's DataSheet.
