| | Lesson |
 | | It is either one section of a textbook (which, apart from the printed page, can also include multimedia) or, more frequently, a short period of time (in many cases 45 minutes) during which learners are taught about a particular subject or taught how to perform a particular activity. |
 | | Lessons can be given anywhere (especially when hands-on experience is called for or when certain materials and/or surroundings are a prerequisite, for example the ocean for a lesson in deep-sea diving), but the majority of lessons are held in institutions of learning, mainly in schools. |
 | | While external factors such as the student-teacher ratio must be taken into consideration, methodological investigations very often focus on explaining, and definitely aim at increasing, students' motivation in the face of difficulties caused by the rigid school system. |
