<![CDATA[Students' perceptions of learning influence the achievement of learning objectives. With the current online learning, students need to have good self-regulation to obtain excellent learning outcomes. Therefore, this study aims to examine the relationship between perceptions of online learning and the self-regulation of Mathematics Education students during the COVID-19 pandemic. The subject of this research is 121 students in semesters 2, 4, and 6 of the Mathematics Education Program in One University in Indonesia. Students in that semester are students who have experienced both face-to-face lectures and online lectures. To collect data in the study, researchers use questionnaires. This study uses descriptive statistical and quantitative analysis techniques. The results showed that student perception of online learning was correlated to student self-regulation during the COVID-19 pandemic (r=0.545 or moderate correlation). It means when students have a good perception of online learning, their self-regulation tends to be good, vice versa. Thus, one way to improve student self-regulation is by increasing student perceptions of online learning.]]>

<![CDATA[The concept image comprises all the cognitive structures in an individual's mind connected with a specific notion. However, if the learning situation is not relevant to help students construct knowledge and provide meaningful experiences, it will affect their concept image. This study aims to examine the concept of the image of the Pythagorean theorem during online-based learning. The research is a qualitative approach, and the method is phenomenological to understand the meaning for the participants of their concept image. Initially, this study enrolled 66 students. Two students were selected as research subjects and acted as resource persons to provide adequate contextualization based on students who answered right and wrong. Data collection combines data from the outcomes of testing the Pythagorean theorem test, interviews, and literature studies. The data analysis technique employed is Interpretative Phenomenological Analysis (IPA). There are six categories of student concept image. Based on in-depth interviews with two students who answered correctly and incorrectly, students were given inconsistent meanings of the Pythagorean theorem due to the learning situation to improve students' understanding of the subject.]]>
