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

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.

Grid Execution

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 is the audit trail for the computation of a data product.

Students collaborate by extending others computations using provenance.

Reusability = Rethinking Our Original DesignQuarkNet/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

Grid work is bleeding-edge and harder than it looks.

Professional development for teachers is critical.

Developers must work within technical constraints of schools.

It’s premature to understand how the Grid enhances education.

We have lessons!
