PEM (Professional Essay Mastery) courses are designed to help individuals of all backgrounds and writing abilities become more proficient in their essay writing skills. These courses provide comprehensive training in all aspects of composition, from structure and sentence construction to research, organization and argumentation. The aim of the course is to give individuals the skills necessary to create well-crafted essays that present a clear, persuasive argument and effectively convey the writer’s thoughts and ideas. PEM courses typically include a review of the basics of English grammar and usage, and then move on to more advanced topics, such as essay organization and rhetorical strategies. Students learn what constitutes good writing style and are also introduced to essay-editing and proofreading. Other course topics may include topics such as literary analysis, argumentation, use of primary and secondary sources, and formulating logical arguments. Many PEM courses are offered in both online and hybrid format. In an online course, all assignments and materials are made available through a learning management system, allowing the student to work at their own pace and eliminate the need for physical textbooks and course materials. Hybrid PEM courses combine online and in-person course elements, making them ideal for those who are unable to attend classes in person. PEM courses can serve as an excellent introduction to essay writing for those with no prior experience, as well as a refresher and way to hone existing writing abilities for those who may have become a bit rusty. For all students, PEM courses can help them become better writers and understand how to better present complex ideas in a clear, eloquent way.
