摘要:During the new coronavirus disease 2019 (COVID-19) lockdown period, the whole educational system from elementary to tertiary levels has been thrown into chaos in Indonesia and around the world. Online modes used by the College of Administration Puangrimaggalatung for learning as well as semester exams are shown in this research. It hopes that it will be able to make better academic decisions in the future when things get tough. The main goal of this study was to look at the need for an online model in education during the COVID pandemic and how educational institutions can use their existing resources to make formal education online with the help of no face-to-face class and other important things. The paper used quantitative and qualitative methods to examine how lecturers and students thought about online teaching learning modes. It also looked at how online teaching learning modes were put into practice. Moreover, the paper is aimed at providing a comprehensive picture of online teaching and learning activities during the lockdown period and demonstrates how the change management process and online teaching and learning processes were linked in the education system during the COVID-19 outbreak. This will aid in the elimination of academic disruption and ensure that instructional activities and discourses may continue as usual in the educational system.
