There are many tools to aid in virtual learning, including virtual classes using audio/video-enabled two-way communication, blogs and wikis where students can share documents and learning products, podcasts that can be used to disseminate lectures, and e-portfolios where students can post work or projects. All of these technologies must be carefully evaluated before use to ensure they actually meet the needs of the students, require technology that is readily available to students, and facilitate interaction between students and the content, students with the instructor, and students with other students.
