Synchronous learning is when classes  occur on set schedules and time frames. Lecturing is an old-fashioned instructional method of delivering information verbally. The term lecture came into use during the 14th century as a verb meaning "to read or deliver formal discourses." All students must be online at that exact time in order to participate in the class. Lecture definition, a speech read or delivered before an audience or class, especially for instruction or to set forth some subject: a lecture on Picasso's paintings. Research shows that information is more easily learned when it is linked to what one already knows. This model represents an oral tradition  that dates back to the Middle Ages. See more. Problem-based learning (PBL) is one of the most commonly used educational methods in medical schools of different countries.

During the lecture session, the instructor wraps up the topic of the week and introduces students to the topic of the upcoming week. Students and instructors are online at the same time in synchronous classes since lectures, discussions, and presentations take place at specific hours. Based on how students are responding, the instructor discusses some of the problems. By working through this method, students think critically, generate ideas, and acquire the knowledge and skills required to become a doctor. But, new advancements in understanding about memory, motivation, and learning indicate a need to rethink how to organize and deliver a lecture. The instructor also gives mini-lectures on some topics that may be difficult to process by students on their own.
