Our online courses, open to visiting high school, undergraduate, and graduate students, are designed to foster active learning and use an interactive style of problem solving that improves student understanding and retention. Our courses are designed to be flexible, with prerecorded lectures, online assignments, and weekly deadlines. Live online sessions, led by the instructor, are held in Zoom, which allows for video, voice, text, screen sharing, and whiteboard interaction. Online course materials, such as videos, notes, interactive webpages, and practice problems with solutions, are provided for the student.

Students can contact their instructors via email with questions or concerns at any time. Live one-on-one online review sessions can be scheduled as well to prepare for the graded assessments, which include homework, quizzes, and a cumulative midterm and final.

The workload in these 4-credit online courses is comparable to those that meet face-to-face. Students should expect to work a minimum of 5-10 hours per week to be successful. This requires that you be self-disciplined, motivated, and have basic skills using a computer and a Web browser.
