QuarkNet

• The primary education program for US-ATLAS and
  US-CMS, large scale experiments
• Developing a research community of physicists,
  high school teachers their students
• Engaging teachers subsequently students in
  scientific investigations

4
Goals of QuarkNet/Grid

• Students participate in a scientific
  collaboration and make real contributions to a
  scientific field.
• Students use virtual data tools and techniques to
  upload, access, process and publish data, report
  their results as online poster, and have online
  discussions about their work with peers.
• Educational researchers evaluate the
  effectiveness of such an endeavor.
• Grid specialists explore interface designs that
  enhance accessibility to Grid data and
  computational resources.

Design Basics for e-Lab

• Requires the GriPhyN Virtual Data System (VDS)
• Serves JavaServer Pages from Apache Tomcat
• Interfaces to local and Grid planners, such as
  Euryale and Pegasus

Transformations Derivations

• Transformations stitch together code into one
  workflow for local or grid execution.
• Derivations invoke transformations with specific
  inputs, like a function call.

Provenance

• Provenance is the audit trail for the computation
  of a data product.
• Students collaborate by extending others
  computations using provenance.

Reusability Rethinking Our Original Design

• QuarkNet/Grid started as a pilot program with
  primary focus on a working model.
• Now, we aim to support new e-Labs using the same
  tools, look and feel, general architecture, etc.
• CMS test beam data is a near-term goal.

We have users!

• 243 teachers
• 240 high schools
• 259 student research groups
• 104 analyses performed since May 2005
• 200 detectors in high schools (with CROP)
• 70 more detectors ready soon

24

We have lessons!

• Grid work is bleeding-edge and harder than it
  looks.
• Professional development for teachers is
  critical.
• Developers must work within technical constraints
  of schools.
• Its premature to understand how the Grid
  enhances education.
