The purpose of this research is to reveal and describe how the self-efficacy of mathematics teachers in Cianjur towards the dynamics of learning during the Covid-19 pandemic. The research was conducted in Cianjur Regency. The methodology used is descriptive quantitative method. The technique of collecting data is through questionnaires given by purposive and snowball sampling techniques. Data analysis uses descriptive statistics which do not aim to make conclusions about the entire population but rather help understand the details of the sample. The results showed that the overall self-efficacy of Mathematics Teachers in Cianjur was in the moderate category. Likewise, four of the seven constructs on teacher self-efficacy are Mathematics Knowledge Self-efficacy (KS), Instructional Self-efficacy (IS), Outcome Expectancy (OE) and Technology Literacy (TL) in the medium category. This means that teachers believe they have the ability to carry out their duties in the midst of a pandemic even though they still need development related to the four constructs. However, the other constructs namely Motivational Self-efficacy (MS), Engagement Self-efficacy (ES), and Disciplinary (as in classroom management) Self-efficacy (DS) are in the high category. This condition shows that teachers are able to provide motivation, students can be actively involved in learning and learning continues to be carried out conducive even though learning is carried out in the midst of a pandemic condition.

The significant influence of the Covid-19 pandemic on the education sector has changed the learning process from face-to-face to online learning. One of the tools used in optimizing the online learning process is the Moodle Learning Management System (LMS). Students' perception of moodle becomes data that is analyzed and interpreted during online learning of mathematics. There are 18 question items distributed via google form using a semantic differential scale of 1-7. Several aspects are examined from the questionnaire, including affective, cognitive and behavioural elements to students in SMP X, data analysis technique by calculating the average of each statement item with the criteria of an average score of <5 Negative response and an average score of 5 then the indicator has a positive response. In addition, the total percentage of students who fill out each indicator is also analyzed to compare the proportions. The data obtained from this study include the affective element of students choosing the benefits of LMS Moodle on a scale of 5-7 by 76%. From the cognitive element of students' perceptions, from 5-7, as many as 68% of students were motivated to learn to use the Moodle LMS during the Covid-19 pandemic. And from the behavioural aspect, 82% of students choose from a scale of 5-7 they choose the emergence of learning independence when using this Moodle LMS.

Mathematics has six material studies in the form of numbers, algebra, measurement, geometry, data analysis and probability, and calculus. This study aims to analyze the learning obstacles contained in each study of mathematics materials. The method used is Systematic Literature Review (SLR). From the Google Scholar database, 7,060 articles match the search string. The screening process based on the 2018-2022 range found 4,560 articles. And then, there are only 275 articles whose pdf is available, and 46 articles were from junior high school level. The last stage is that there are 13 journals that examine the three learning obstacles, such as ontogenic obstacles, epistemological obstacles, and didactical obstacles. No matching articles were found in the ERIC and Garuda databases. This article analyzed mathematics material and obtained learning obstacles from each study of the materials. Ontogenic obstacles are lack of motivation, student learning interest, and student readiness to learn, as well as short-term memory abilities, epistemological obstacles in the form of students' understanding of concepts and the use of formulas that are not yet appropriate, and didactic obstacles in the form of using teaching methods and materials that do not help students understand the material well.

Linear programming is a contextual material in mathematics learning. But there are facts that show that there are still mistakes and difficulties experienced by students in linear programming problems. This study aims to conduct a literature review on mathematical abilities of students, errors and difficulties in linear programming problems. This study uses the SLR (Systematic Literature Review) research method. Data collection in this study was carried out by documenting and reviewing all articles regarding mathematical abilities of students, errors and difficulties on linear program problems published in the 2016-2022 period. This study used 40 accredited articles obtained from Google Scholar and Scopus. Based on this research, it was found that mathematical abilities of students to solve linear programming problems was still low. Students still make many errors in drawing conclusions and encoding errors, and still have difficulties in understanding concepts, making mathematical models and performing correct mathematical procedures.

Critical thinking is critical analysis and assessment ofÂ problem to makeÂ decision. Critical thinking is essential aspect to improve studentsâ€™ problem solving skills. The purpose of this research is to analyze qualitative studies on students' critical thinking skills in primary, secondary, tertiary and higher education, from 2013-2023. This research uses Syistematic Literature Review (SLR) which categorizes primary data from previous publications in proceedings journals, indexed by Sinta and Scopus. Data extraction was adjusted to the selection criteria, so that 27 articles were collected. Qualitative methods were used to analyze the data. Data grouping was based on publication year, education level, demographics, indexed journals, material analyzed, and research results. The results showed that research related to critical thinking skills became a trend in research conducted in 2013-2023 for algebra topics. Many studies related to critical thinking skills were conducted on the Asian continent. However, students' critical thinking skills are still low for all levels of education. Based on critical thinking indicators, students have difficulty in evaluating. This is because students do not really understand the basic concepts of mathematics. As a result, this is a concern for researchers and educators to conduct research related to students' critical thinking skills.
