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.

This study aimed to 1) to find out the effectiveness of the integration technique module in integral calculus learning, and 2) to find out the increase in the mathematical creative thinking ability after implementing the integration technique module in integral calculus learning. The development of module was conducted by using ADDIE model with five stages: Analysis, Design, Development, Implementation, and Evaluation. The subjects in this study were 16 students in the 3rd semester of Mathematics Education Study Program, the Faculty of Teacher Training and Education, Universitas Riau. The research instruments were an expert validation questionnaire, a student response questionnaire, and a mathematical creative thinking ability test. The data obtained were analyzed by using quantitative and qualitative descriptive analysis methods. Based on the results of the validity test, the integration technique module was declared valid and suitable for students to use in the integral calculus course. Judging from the results of the module practicality test, the average percentage of practicality values was 77.8125 and was in the practical category. Referring to the results of the module effectiveness test, the n-gain average of students' mathematical creative thinking abilities was 0.64 and in the medium category. Because the integrated engineering module met the criteria of validity, practicality, and effectiveness, it could be stated that the developed integration technique module improved students' mathematical creative thinking skills in the integral calculus course.

Perubahan paradigma pembelajaran tatap muka ke daring akibat pandemi Covid-19, memunculkan berbagai pandangan mahasiswa terkait pelaksanaan pembelajaran daring. Berbagai penelitian sudah membahas persepsi tersebut, tetapi masih sedikit yang membahas instrumen pengukurnya. Berdasarkan hal tersebut, tujuan penelitian ini adalah menghasilkan instrusmen angket untuk mengukur persepsi mahasiswa pendidikan matematika terhadappembelajaran daring yang valid juga reliabel. Penelitian ini adalah penelitian pengembangan ADDIE. Subjek dari penelitian ini yaitu dua validator yang merupakan dosen ahli dan 59 mahasiswa pendidikan matematika Universitas Riau sebagai responden. Penelitian ini memperoleh data kualitatif dan kuantitatif dengan teknik analisismenggunakan deskriptif kualitatif dan deskriptif kuantitatif. Nilai validitas dan reliabilitas angket berturut-turut sebesar 0,495 dan 0,85 yang berarti kriteria valid juga reliabel terpenuhi. Angket yang dihasilkan memuat 21 butir pernyataan yang mewakili 12 indikator, yaitu masing-masing 1 butir pernyataan untuk indikator menumbuhkan sikap aktif dalam proses pembelajaran, menumbuhkan motivasi dalam proses pembelajaran, dan menumbuhkan sikap belajar mandiri; masing-masing 2 butir pernyataan untuk indikator meningkatkan pemahaman, penyajian materi kuliah yang diharapkan, pengelolaan kelas yang diharapkan, penilaian yang diharapkan, akses yang diharapkan, penyajian materi kuliah yang terjadi, pengelolaan kelas yang terjadi, penilaian yang terjadi, dan akses yang terjadi. The change in the paradigm from face-to-face learning to online due to the Covid-19 pandemic has raised various student views regarding implementing online learning. Various studies have discussed this perception, but few discuss the measuring instrument. So, this research aims to produce a questionnaire instrument to measure the perceptions of mathematics education students towards valid and reliable online learning. This research is ADDIE development research. The subjects of this study were two expert lecturers as validators and 59 students of Mathematics Education at the Universitas Riau as respondents. This study obtained qualitative and quantitative data using analytical techniques using qualitative and quantitative descriptive. The validity and reliability values of the questionnaire are 0.495 and 0.85, respectively, which means that the valid criteria are also reliably met. The resulting questionnaire contains 21 statements representing 12 indicators, namely 1 statement each for indicators of growing an active attitude in the learning process, growing motivation in the learning process, and fostering an independent learning attitude; 2 statements each for indicators of improving understanding, presentation of expected lecture materials, expected class management, expected assessment, expected access, presentation of lecture material that occurs, classroom management that occurs, assessment that occurs, and access that occurs.

Perubahan pelaksanaan kegiatan pembelajaran yang semula dilakukan secara tatap muka harus dilakukan secara daring akibat munculnya virus Covid-19. Pelaksanaan pembelajaran daring sampai saat ini masih memiliki kekurangan di beberapa hal, seperti pencapaian kemampuan berpikir kreatif matematis yang belum optimal akibat kurangnya keterlibatan mahasiswa dalam kegiatan belajar mengajar. Hal ini menyebabkan, mahasiswa memerlukan bahan ajar seperti e-LKM yang tidak hanya bisa meningkatkan aktivitas mahasiswa tetapi juga kemampuan berpikir kreatif matematis. Jenis penelitian yang dilakukan adalah penelitian kualitatif deskriptif dengan instrumen penelitian berupa es kemampuan berpikir kreatif matematis, kuesioner, pengamatan, analisis bahan ajar, dan wawancara. Hasil penelitian menunjukkan bahwa mahsiswa membutuhkan e-LKM yang memuat petunjuk, kegiatan, atau langkah kerja, dapat digunakan secara mandiri dimanapun dan kapanpun, serta dapat meningkatkan aktivitas mahasiswa dalam belajar sekaligus meningkatkan kemampuan berpikir kreatif matematis.

This study aimed to determine the difference in self-regulation of students of Mathematics Education FKIP Riau University during online lectures regarding gender. The subjects of this study were students of Mathematics Education FKIP Riau University batch 2017, 2018, and 2019 as many as 30 students, with details of 15 male and 15 female students. To collect data in this study, the authors used a self-regulation questionnaire. After the self-regulation questionnaire is valid and reliable, the questionnaire is then distributed to students who are research subjects. The self-regulation score data was then processed using descriptive statistical techniques. The results of data processing are then interpreted for each gender. Next, to see if there is a difference in self-regulation between students who take online lectures between male and female students, a t-test is carried out. Based on the results obtained, it can be concluded that there is no significant difference in self-regulation between male and female students. As a follow-up, lecturers can provide equal treatment between male and female students to optimize self-regulation. However, if we look at each indicator, there are indicators of task strategy and seeking help that reach different score categories between male and female students.
