On March 16, 2020, many universities in Indonesia began implementing online-based learning to replace lectures in the classroom. This is done as a way to reduce the transmission of the Covid-19 outbreak in Indonesia. There is an opinion that with the implementation of online learning, especially in mathematics education study programs, there are many obstacles when learning takes place. This study aims to determine the obstacles that arise after the implementation of online learning in mathematics learning in Higher Education. This research is a qualitative case study, assisted by an online survey. The researcher collected data through an online survey consisting of 27 questions. The survey is aimed at lecturers who teach in Mathematics Education study programs in Indonesia. The survey contains structured questions and leads to three parts, namely; basic skills challenges, teaching and learning challenges, and university challenges. The 27 questions contained questions about the ability of platform mastery to support online learning owned by each lecturer. The research involved 26 lecturers from universities in Sumatra, Java, Kalimantan, and Sulawesi. The results of this study reveal that all lecturers affected by the pandemic use a Learning Management System (LMS) based website as a means of online learning. The learning management system-based platform is the most widely used (google class and Edmodo) while video conferencing is the second choice (Zoom and Skype). What is interesting is that the LMS available on campus is less attractive to lecturers. However, there are obstacles faced such as the limitations of writing mathematical symbols and the limited basic capabilities of the learning management system and multimedia software to support online learning.

Abstract.The education sector has also felt the impact of the Covid-19 pandemic, which can be said to be quite significant. The online learning policy launched by the government has been accepted and implemented by schools without careful planning. Teachers as the frontline in facilitating learning really feel the decline in the competence and quality of students' human resources, especially in mathematics subjects caused by students' relatively low critical thinking skills. This condition was complained by members of the Mathematics MGMP of Purworejo Regency. The complaint was then answered by the service team through community service activities by implementing a mathematics learning model to stimulate critical thinking. The purpose of implementing this massive learning model is to increase the innovation and competence of teachers of the Mathematics MGMP members of SMA Purworejo in implementing learning that can stimulate students' critical thinking skills. Community service activities will be carried out on December 21-24 2021 with the target of the Purworejo Mathematics MGMP. The stages of activities include socialization, dissemination, implementation, and evaluation. Through this activity, MGMP members gain a lot of knowledge related to learning models and students' critical thinking skills, gain inspiration and innovation in implementing mathematics learning, and through implementation in students, teachers can ultimately improve students' mathematical critical thinking skills. Abstrak. Sektor pendidikan turut merasakan dampak pandemi Covid-19 yang dapat dikatakan cukup signifikan. Kebijakan pembelajaran daring yang dicanangkan oleh pemerintah diterima dan diimplementasikan oleh sekolah tanpa perencanaan yang matang. Guru sebagai garda terdepan dalam memfasilitasi pembelajaran sangat merasakan turunnya kompetensi dan kualitas SDM siswa terutama pada mata pelajaran matematika yang diakibatkan oleh kemampuan berpikir kritis siswa yang relatif rendah. Kondisi ini dikeluhkan oleh anggota MGMP Matematika Kabupaten Purworejo. Keluhan tersebut kemudian dijawab oleh tim pengabdi melalui kegiatan pengabdian masyarakat dengan implementasi model pembelajaran matematika untuk menstimulasi berpikir kritis. Tujuan kegiatan implementasi model pembelajaran secara massive ini diharapkan dapat meningkatkan inovasi dan kompetensi guru anggota MGMP Matematika SMA Purworejo dalam melaksanakan pembelajaran yang dapat menstimulasi kemampuan berpikir kritis siswa. Kegiatan pengabdian masyarakat dilaksanakan pada tanggal 21-24 Desember 2021 dengan sasaran MGMP Matematika Purworejo. Adapun tahapan kegiatan meliputi sosialisasi, diseminasi, implementasi, dan evaluasi. Melalui kegiatan ini, anggota MGMP memperoleh banyak ilmu terkait model pembelajaran maupun kemampuan berpikir kritis siswa, memperoleh inspirasi dan inovasi dalam melaksanakan pembelajaran matematika, serta melalui implementasi pada siswa pada akhirnya guru dapat meningkatkan kemampuan berpikir kritis matematis siswa.

Mathematics is one of the basic concepts needed by students at every level of education. However, students often have difficulty in understanding mathematics. This can be seen from the mistakes made when working on math problems. Errors made by students must be addressed immediately so that no more errors occur, especially on questions that have the same characteristics. The purpose of this study was to determine the percentage of conceptual errors, arithmetical errors, writing errors and the most common mistakes made by students on the subject of exponential and logarithmic equations. Sampling was done by using purposive random sampling technique. The data in this qualitative descriptive study were collected using test, interview, and documentation techniques. The instrument used to collect data was in the form of test questions and interview guide sheets. The data were analyzed by categorizing the types of errors into conceptual errors, arithmetic errors, and writing errors and then calculating the percentage of errors in each category. The results showed that the errors made by students in each category were conceptual errors of 53%, arithmetical errors of 34.78% and writing errors of 28.99%. The error that many students make is a conceptual error as much as 53% with a moderate error percentage category.

This study aims to describe and determine mathematical critical thinking skills based on students' self-esteem. This research used a mixed method with a sequential explanatory research design. The research population was first year mathematics education students who took geometry courses, and the research samples were selected by way of purposive sampling technique. Research subjects were grouped based on high, medium, and low self-esteem categories to be interviewed about students' critical thinking skills. The research instruments were tests and interviews. The results showed that students had various mathematical critical thinking skills in terms of self-esteem. Four students possessed a high level of self-esteem as indicated by the fact that two students’ mathematical critical thinking skills results were classified in high category while the remaining two students were in medium category. Of 25 students who had moderate self-esteem, 5 students obtained high category in the results of their mathematical critical thinking skills, 14 students had their result in moderate category students, and 6 students were in the low category. Of 3 students with low self-esteem, one student had their results of the mathematical critical thinking ability result in the high category and two students had their result in the low category. It can be concluded that there is less significant correlation between self-esteem and students' critical thinking skills. Meanwhile, there are three different levels in students' critical thinking skills in terms of self-esteem at high, medium, and low levels.

The Covid-19 pandemic in various countries has had an impact on changes in the education system. The implementation of learning has changed from classroom to online learning. The implementation of online learning certainly affects the learning interest of students. This study was conducted to determine student interest in learning during the Covid-19 pandemic. The subjects in this study were students of the Mathematics Education Study Program at a private university in Yogyakarta as many as 72 students who were selected using the simple random sampling method. The data in this study were collected through Google Form questionnaire. The questionnaire contains 15 items of multiple choice and each item contains “why” question to obtain in-depth data about the answers given by respondents. The data of questionnaire analyzed descriptive qualitatively. The results indicated that students' interest in online learning needed to be insreased. It can be seen from students’ responses to the questionnaire that only 15.3% of students gave a positive response to online learning and 32% to online exams. In general, students prefer classroom learning compared to online learning in terms of student attendance, interaction of lecturer-students, and technical in learning. Online learning tends to reduce student interest in attending lectures. Limitations of internet access, lecturer delivery methods and the amount of workloads are factors causing the decline in student interest. By knowing students' interest in learning and the factors that cause low students’ interest in learning, lecturers can improve the quality of learning to increase student interest in online learning.
