Being a lecturer/speaker means more than just talking. A lecturer/speaker has a responsibility to his or her student, as any professor would, as well as to his or her fellow instructors. Lecturers/speakers will spend a considerable amount of their time teaching students and building curricula. In addition to these tasks, they will need to develop course materials, attend faculty meetings, and generally test and evaluate students as needed. Once lecturers/speakers become more experienced at their work, they will have to help new instructors by showing them how to be successful and by demonstrating their responsibilities firsthand. If a student should ever need help, a lecturer/speaker must be available by having office hours so that students can reach him or her.
Lecturers have to be more than just professors. Not only do they need at least a master's degree in teaching or education, but they also generally must have years of work as a professor. This experience allows them to more thoroughly understand their duties and puts them in a position in which they may best demonstrate leadership or administrative prowess as situations call for it. Lecturer/speakers must demonstrate a firm grasp of the topic that they are speaking about, and they must show that they have a profound understanding of it that allows them to convey that information meaningfully. Source material and teaching material are also important for lecturers/speakers to know. Not only will they need to review and determine what textbooks are necessary for their classes, but they will also need to evaluate and assign reading materials for their classes.
