New York, NY, July 11, 2007 — Computer science teachers now have access to the largest collection of K-12 computer science teaching materials in the country, thanks to the Computer Science Teachers Association (CSTA). The organization today launched its Source web repository and is offering the resource free of charge to its members through its web site at

CSTA´s Source web repository offers more than 75 resources in a searchable, downloadable collection, including lesson plans, learning modules, code segments, presentations, and even complete course descriptions. Educators can also access information about how to promote their computing courses.

"The Source repository will be a constantly evolving database of teaching materials, launched by CSTA to make it easier for computer science instructors to incorporate well-researched and up-to-date material into their lessons," said Chris Stephenson, executive director of CSTA.

All of the materials in the searchable database have been classified in accordance with the ACM Model Curriculum for K-12 Computer Science so teachers can easily identify resources to use for specific courses and student learning levels. Users can also search on keyword, author, and submission date.

All of the materials included in the Source repository have been reviewed by a volunteer committee of educators from all education levels to make sure that they are classroom ready and classroom appropriate

Stephenson notes that CSTA is also encouraging teachers and vendors who have created good curriculum materials for computer science education to submit these items for inclusion in the Source. "The Source is completely vendor and software neutral and we encourage everyone to submit good materials to help improve teaching and learning," said Stephenson.

The Source web repository and all of its resources are open to submission and viewing by anyone but free full-text downloads are restricted to CSTA members. Membership in CSTA, however, is free, and anyone can become a member by visiting the organization´s web site at
