Lesson

A lesson or class is a structured period of time where learning is intended to occur. It involves one or more students (also called pupils or learners in some circumstances) being taught by a teacher or instructor. A lesson may be either one section of a textbook (which, apart from the printed page, can also include multimedia) or, more frequently, a short period of time during which learners are taught about a particular subject or taught how to perform a particular activity. Lessons are generally taught in a classroom but may instead take place in a situated learning environment. In a wider sense, a lesson is an insight gained by a learner into previously unfamiliar subject-matter. Such a lesson can be either planned or accidental, enjoyable or painful. The colloquial phrase "to teach someone a lesson", means to punish or scold a person for a mistake they have made in order to ensure that they do not make the same mistake again. Lessons can also be made entertaining. When the term education is combined with entertainment, the term edutainment is coined. The potential format and speaks to one or more people in the same room or space. This may be supplemented with gestures and tools. A lesson may range from a lecture, to a demonstration, to a discussion or a blend of some of these common presentation methods. Some lessons may involve work by the student. Traditionally this might include reading and writing or creating something, perhaps when the instructor is not present. The student may work independently or collaborate with others. More recent technologies have expanded the way a lesson can be delivered. For example: film strips, pre-recorded audio and video tapes, television programs and podcasts are some ways to deliver or add to a lesson. Distance education techniques such as video conferencing, or electronic learning in a virtual learning environment have allowed interactive lessons to be presented to students who may not be in the same physical location. These tools offer new synchronous, asynchronous and blended ways to deliver lessons.
