The Relationship between Perceptions of Online Learning and Self-Regulation of Mathematics Education Students
Full text linkStudents' 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
Students' Critical Thinking Process in Solving Jumping Task According to Gregorc's Thinking Style
Full text linkIndonesian students are lacking in critical thinking skills, however, studies analyzing critical thinking processes and their relation to thinking styles are limited. This study aimed to describe students critical thinking processes in solving jumping task problems according to Gregorc's thinking style. The subjects of this present qualitative research were eight Year 7 students. The instruments included a thinking style questionnaire, tests, and interview guidelines. The results showed that concrete sequential subjects tended to write the completion stages sequentially and analyzed them well. Abstract sequential subjects were inclined to solve the problems based on the known concepts without completing the work. Concrete random subjects tended to write information in their own way without completing their work. Meanwhile, abstract random subjects were inclined to write incomplete information and did not complete their work. Generally, based on the IDEALS model, the two sequential subjects were similar in the identity, define, and enumerate steps, while the two random subjects only had similarities in the identity step. This study results imply that jumping tasks can be used as an alternative in developing students critical thinking skills

Improving Teachers Self-Efficacy through Training: An Impact for the Freedom of Students Mathematical Thinking
Full text linkTeacher self-efficacy is an important component of teacher competence. At present, efforts to improve teacher competencies have not been carried out simultaneously for teacher activities in the classroom (open class) and outside the classroom (training). This quasi-experimental study aimed to examine the effectiveness of soft skills training and the practice of lesson study on improving mathematics teacher self-efficacy and describe the impact of teacher self-efficacy on the freedom of students' mathematical thinking. The study involved three mathematics teachers and 90 students from three different junior high school regions in Bandar Lampung, Indonesia (city center, semi-urban, and suburban). Data was collected through questionnaire, observation, and interview. The data were then analyzed descriptively. The effectiveness of soft skills training and the practice of lesson study on improving mathematics teachers self-efficacy was examined using Wilcoxon Test. The results showed the differences in the average teachers self-efficacy before and after participating in soft skills training and the practice of lesson study (with an increase of 0.82/high). The increase in teachers self-efficacy also positively affected the freedom of students mathematical thinking
Profil Kemampuan Berpikir Kritis Mahasiswa dalam Menyelesaikan Soal Pemecahan Masalah Matematika Ditinjau dari Jenis Kelamin
Full text linkCritical thinking is a careful and calculated thinking activity using complex reasoning. The purpose of this study is to describe the students' ability to think critically in solving problems based on gender. The research subjects were two second semester students of Mathematics Education Program Universitas Pendidikan Mandalika. The instruments were a mathematics problem-solving sheet and interview guidelines. Data were analyzed qualitatively by three stages: data reduction, data presentation, and concluding. The results of the study found that the two subjects could bring up the five indicators of critical thinking. The male student was better in providing analytical analysis on the further explanation of the solution given, and the female student was better providing a complete, clear and detailed explanation so that it takes a longer time. However, the two students could not accurately draw conclusions and analysis. It is recommended that the lecturer provides various questions with different levels so that students are accustomed to thinking critically and they, later, as teachers also can train students' critical thinking
Pengembangan Soal Higher Order Thinking Skills (HOTS) pada Materi Aljabar di Sekolah Menengah Pertama
Full text linkThe Indonesian curriculum year 2013 requires students to have Higher Order Thinking Skills (HOTS) that match the competence needs in 21st century. Based on international assessment, Indonesias student rank is insufficient because the student is not familiar with solving problems requiring reasoning and analysis, including topic of algebra. This research aims to produce HOTS questions about algebra at Junior High School, which is valid, practical, and effective. This research is development research which consists of two stages, namely preliminary and formative evaluation. The participants in this study were grade 7 and 8 students in one Junior High School at Banda Aceh, Indonesia. The instruments were validation sheets, student response questionnaires, practicality test questionnaires, and HOTS questions. The result shows that the HOTS algebraic questions were meet the criteria: valid because all validators stated that the HOTS questions are suitable to use and the average value of the validation was reach very valid criteria; practical because all validators suggested that the learning tools can be applied in the class; effective because students response toward problems was positive dan the ability of students to solve questions is diverse. Thus, these HOTS questions can be used at the junior high school level
