Description

Method for Managing and Supervising Online Lecture Students and System for Implementing the Same The present invention relates to a method for managing and supervising online course students and a system for implementing the same. Starting with the growth of the online education market targeting students and exam takers, online courses are being actively utilized in various educational fields—including vocational training, corporate in-house training, early childhood education, foreign language education, and general education and hobby fields—to replace or supplement offline methods. Recently, due to the impact of the pandemic, not only has reliance on online course systems increased dramatically, but there has also been a surge in cases where non-face-to-face activities are being conducted even outside of course attendance, such as exams and assessments. However, despite the increasing demand and utilization of online course enrollment and non-face-to-face assessment methods, there are many instances of inconvenience due to the lack of proper systems for their management and supervision. For instance, when verifying online course attendance or checking results, it is practically difficult to ensure clear verification unless students voluntarily maintain an honest attitude. In particular, it is impossible to expect a level of fairness comparable to offline exams during non-face-to-face assessments conducted alongside online courses. Furthermore, in addition to aspects of accuracy and fairness, there is a need for the management and supervision of online course students as a safety measure. Online courses are made available to be taken via portable electronic devices, such as mobile phones or tablets, rather than PCs, to ensure student convenience and time autonomy. Consequently, there is a risk of safety issues arising if students take courses while driving or walking.
