SAM Learning, publisher of Web-based curriculum for high school exit exam prep, now offers science content in biology, chemistry, and physics.

In addition, "Improvement Lessons" with audio support have been added to selected objectives to help students refresh their understanding of intermediate and advanced mathematics or to learn critical concepts in another manner.

The new content is aligned to national learning standards and state standards for California, Florida, Georgia, Texas, and New York. Seven additional states will be added in fall 2008.

SAM Learning uses a scaffolded pedagogy and student-driven learning that enables students to navigate through the program in a manner that makes sense to them. Teachers can assign exercises or allow self-directed student work.
