As you research the right online program for you, you may come across the terms “asynchronous” and “synchronous." You might not know what these words mean yet, but you’re probably already considering your work schedule and other responsibilities and how well each program would fit into your life. Are you able to log on and attend classes at specific times? Or is it more realistic for you to complete work each week at times that suit you best – no matter if it’s 3 p.m. or 3 a.m.? And, how do online classes even work?
Here's what you should know: Asynchronous online learning allows students to view instructional materials each week at any time they choose and does not include a live video lecture component. On the other hand, synchronous online learning means that students are required to log in and participate in class at a specific time each week. The main difference between asynchronous learning and synchronous learning is this live instruction component occurring at a set time. We'll describe more differences in the sections below, as well as some of the pros, cons and best practices of each style.
We tapped Ohio State experts to explain the difference between asynchronous and synchronous learning and what each style actually means when it comes to online classes.
Asynchronous online classes: complete work each week on your schedule, receive immediate feedback on quizzes, schedule group work when it's convenient for everyone.
Synchronous online classes: attend class virtually each week with instructors and classmates, participate in real-time discussions during class time, improve presentation skills.
Both: attend class from anywhere*, communicate regularly with instructors, network and make connections with classmates.
*The majority of our programs have no on-campus requirements. Please see your specific program's page for state authorization information.
What is asynchronous learning?
Asynchronous learning allows you to learn on your own schedule, within a certain timeframe. You can access and complete lectures, readings, homework and other learning materials at any time during a one- or two-week period.
“A big benefit to asynchronous classes is, of course, the flexibility. Asynchronous online classes mean that you don’t always need to be online at the same time as your instructor or classmates,” said Instructional Designer John Muir, who works with faculty to develop classes for Ohio State's online programs. “We know that students who are looking to take an entire program online are partially looking for that flexibility.”
Online asynchronous classes might include short videos teaching key concepts that you can watch over and over again, if necessary. In some classes, students can also complete homework assignments and receive immediate feedback, as opposed to waiting for instructors to grade them.
But don't get the idea that asynchronous classes are any less rigorous than their synchronous or on-campus counterparts.
“Just like a student on campus, you should expect to be doing work one week at a time,” Muir said. “You should also expect to have contact with your instructor and classmates every week in a substantial way.”
For example, in HTHRHSC 4300: Contemporary Topics in Health and Society, a capstone course in the B.S. in Health Sciences program, students do most of their work according to their own schedules. However, they also sort themselves into groups based on schedule and availability, meeting weekly via video conferencing to collaborate on a research project that spans the semester.

What is synchronous learning?
Synchronous learning means that although you will be learning from a distance, you will virtually attend a class session each week, at the same time as your instructor and classmates. The class is a firm, weekly time commitment that cannot be rescheduled. Much like an on-campus class, you will have readings and assignments to complete outside of class time to help prepare you to participate in the discussion. This kind of preparation from students, along with a dedicated agenda set by the instructor, ensures each class session is productive.
“A lot of careful planning and set up ahead of time makes those sessions into meaningful connections," Muir said. “If the students can do it, and it’s thought through well by instructors, it can be a really powerful thing to add.”
Online synchronous learning doesn’t always just take the form of a live video lecture or an instructor-led discussion. Often, students will lead discussions themselves or give presentations to the rest of the class. In an online class, group work doesn’t go away, it just looks a little different. Muir explains that some instructors will pose case studies to students, who then have to negotiate an answer first as a small group and then together, as a class. Specific types of activities included in a synchronous course depend on the course and the program.
“There’s a lot of discipline-specific, really active things that go on in those sessions that aren’t just the equivalent of a recorded lecture,” Muir said. “It really is the same as doing some sort of activity in the classroom, just in a virtual setting.”
Ohio State's Doctor of Nursing Practice program is one example of a program with synchronous online class requirements. One of the classes, NURSPRCT 8600: Organizational Culture, requires that students attend weekly evening class sessions using CarmenZoom. Class discussion and interaction with the instructor occurs mainly during these meetings, with homework and readings available at any time in CarmenCanvas, Ohio State's online learning management system.
