I found Mahara to be a very interesting educational program.
Mahara is designed to be a blog, social networking site, resume builder, file depository. Already used by schools and institutes, Mahara is a powerful tool which promotes user interactivity and learning.
High school business classes could benefit through this, by getting students to create portfolios on their career aspirations and building resumes for potential jobs. They could track their process and learning experiences through the blog section, upload assignments to the file depository and keep track of their peers progress.
