I teach at a college for working adults. Most of our students work at least one job and have many family obligations. In short, they are busy people looking to learn in the most efficient and effective way possible. To meet these needs, we offer online classes that include a weekly 90-minute synchronous session (attendance optional), which is recorded and posted within the course along with copies of any materials that were discussed. Real-time interaction with the professor is available through weekly virtual office hours and by appointment.
