Trend of learning management system (LMS) platforms for science education before-after Covid-19 pandemic

The Covid-19 pandemic made massive changes in the world of education. Here we conducted a study on the trend of LMS platforms before and after the Covid-19 pandemic. Data on occasion before the Covid-19 pandemic was obtained from research article publications related to the type of LMS platform in the last ten year period. Meanwhile, data on occasion after the Covid-19 pandemic was obtained through questionnaires to junior high school science teachers in various regions in Indonesia, with bachelor's degrees and master's degrees and also different teaching experiences. The result on the first occasion data shows that before the Covid-19 pandemic, the Moodle type was mostly used by educators than other types such as Edmodo, Classdojo, Schoology, Brightspace, Google Classroom, and the Microsoft Team, both at school and in the higher education. The result on the second occasion data shows the opposite, where after the Covid-19 pandemic, the Google Classroom type was superior to the other types. It is due to the practical, speed, and satisfaction of using both platforms.
