What is the relationship between self-regulated learning and students' mathematical understanding in online lectures during the covid-19 pandemic?

Covid-19 pandemic forced online lecturing and learning from home (LFH) to be carried out on all campuses in Indonesia. One obstacle in implementing LFH is how students can organize themselves so they can learn well from home. Based on observations in class, students who can manage their learning (Self-Regulated Learning, SRL) well tend to better understand the mathematical material provided. Mathematical understanding is very important because it becomes the basis for students to be able to master other higher mathematical abilities. The purpose of this research is to determine the relationship between self-regulated learning and students' mathematical understanding in online lectures during the covid-19 pandemic. This research is qualitative descriptive research. The subjects in this research were 14 students contracted discrete mathematics courses on mathematics education department at Wiralodra University in the 2019/2020 event semester by purposive sampling technique. The instruments of this research were self-regulated learning questionnaires, mathematical understanding tests and interviews. Data analysis consist of data reduction, data display, and conclusion drawing/verification. The results showed that there are directly proportional relationship between self-regulated learning and students' mathematical understanding. Based on these findings, it is necessary to apply self-regulated learning strategies in lectures to improve students' mathematical understanding.
