Massive Open Online Courses (MOOCs) are free and open for any learner classes taught in an online environment (Alraimi, Zo, & Ciganek, 2015). In recent times, this phenomenon has become widespread. This paper examines the advantages and disadvantages of MOOCs and compares them with traditional online courses. On the example of my career, I describe the main reasons to choose MOOCs and consider whether these classes are relevant. Finally, the future and potential of MOOCs are explored. Advantages and Disadvantages of MOOCs The massive open online course model has several advantages that refer to all participants. First and foremost, it is the great diversity of ideas, opinions, and perspectives that resembles the openness exhibited by individuals in everyday life (Alraimi et al., 2015). Since persons from all over the globe may enroll in such courses, they share their experiences and views and simultaneously receive a wide range of information. Another advantage is the benefit of distributing responsibility for teaching: peer assessment is an integral part of learning ( 7 things , 2011). Finally, MOOCs bring profit to colleges and universities that offer such opportunities: because a larger audience can have access to the materials, these institutes lower barriers to knowledge and outspeak in the community. As for MOOCs’ disadvantages, they deal with a great number of people. For some learners, contacts with the instructors are significant, but the format of MOOCs implies that most of the work is to be discussed with peers. In other words, there is little “teaching presence” (Bali, 2014). Further, some learners may be annoyed or distracted by nonlinear streams of information and multiple conversations in different platforms that occur simultaneously ( 7 things , 2011). As a result, people may feel overburdened. The third drawback is the possibility of improper behavior. Overall, the possible problems are more relevant to individuals and their personal preferences in teaching modes while the benefits of MOOCs are important for every learner. MOOCs and Traditional Online Courses The principle of online learning is not new: traditional online courses also take place in education. They have several common features with MOOCs but still differ. Both types are similar in training aids: videos, readings, and other materials are suggested. They are offered online. Students complete assignments, submit them and receive their grades automatically. In most cases, there are some admission requirements, for example, a student should provide their e-mail and some personal data. Both MOOCs and traditional online courses have fixed starting and finishing dates. If a person wants a credential, they need to pay for learning. As for the differences, MOOCs may be subdivided into two groups: courses with a similar to traditional course structure where content is formed by instructors (“xMOOC”) and course materials derived from students during the course (“cMOOC”) (Alraimi et al., 2015). In comparison, traditional online courses are predefined by educators only. The platforms on which these types are offered are also different: as a rule, MOOCs are based on Coursera,
