RICHMOND, Va. (AP) — Virginia high school students are learning more about personal finance and economics thanks to two digital textbooks developed by the state Department of Education.

Gov. Bob McDonnell says the iBook textbooks will help students earn the now-required diploma credit in the topic areas.

In 2009, the Board of Education voted to require students to earn a credit in economics and personal finance to graduate with either a standard or advanced studies Diploma. The requirement became effective with students who entered the ninth grade during the 2011-2012 school year.

The books contain 2,600 pages of digital content, including graphic-novel scenarios, interactive activities, graphing tools, embedded review questions, and self-grading assessments. They are fully aligned with the Virginia Economics and Personal Finance Standards of Learning.
