To prepare students to compete in 21st-century skills, the Ministry of Education and Culture of the Republic of Indonesia integrates character education into school subjects. However, as a medium, comics do not contain the level of character values, exploration, and critical thinking skills in problem-solving on geometry material. Therefore, the aim of this study is to produce digital media based on character values on mathematical critical thinking skills in solving problems related to learning styles for eighth-grade students. This development research employed the 4-D method (Define, Design, Develop, and Disseminate). The study indicates that the digital comic learning media is valid with a total average score of 3.60 based on the material expert’s validation and 3.50 based on the media expert’s validation. The eight-grade students' responses were positive (92%) based on the trials. The learning outcomes in terms of kinesthetic, auditory, and visual learning styles used in this study can all meet all indicators of mathematical problem-solving.

Higher-order thinking (HOTS) problems are a learning assessment system applied to the curriculum in 2013 to improve students' higher-level thinking skills. However, teachers still familiarize students to solve problems with low-level thinking, which lower the Indonesian students’ mathematical literacy. This descriptive research with a qualitative approach aimed to explore junior high school students’ mathematical literacy skills in Kotapinang in solving HOTS problems applied to the curriculum 2013. Four students were selected as research subjects. Research instruments consisted of mathematical skills tests, literacy tests, and interviews. The researchers applied the triangulation techniques with Miles and Huberman’s model as the data analysis technique. The analysis showed that students’ mathematical literacy skills in Kotapinang were poor. The researchers recommend applying technology-based learning models, such as blended learning that is suitable for limited face-to-face learning to support the improvement of mathematics literacy skills of junior high school students in solving HOTS problems in the curriculum 2013.

Assessment is an essential part of the learning process in higher education. As a result, the assessment should involve students in addition to lecturers. The purpose of this study is to examine the self and peer assessments on the answers to midterm and final-semester exams given by lecturers and their relationship with student achievement. The participants in this study were 114 fifth-semester mathematics education students who took differential equations courses. Data were gathered from student assessment scores on the middle and final test and student achievement in the lecturer's differential equations courses. The data were analyzed using descriptive statistics and an independent sample t-test to describe the self and peer assessments. Pearson correlation analysis was also used to describe the relationship between self and peer assessment and learning achievement. The study revealed no significant difference between self and peer assessments, both midterm and final semester assessments. The midterm assessment said that the average self-assessment was higher than peers. Meanwhile, the assessment average scores obtained in the semester's final exam were nearly identical between the two assessors. There is a positive and significant correlation with a high level of self and peer assessments, both in the midterm and final semester, and a positive and significant correlation with a moderate level of self and peer assessments with learning achievement. These findings can be used as a basis for lecturers to consider when involving students in assessing student achievement.

Students’ metacognition abilities based on their aspects have different levels. Metacognition aspects had categorized into parts of awareness aspects, evaluation aspects, and aspects of regulation. This study aims to describe how students are metacognitive in solving non-routine problems based on awareness, evaluation, and regulation characteristics. This research is a descriptive qualitative study with a sampled class VIII A Junior High School Batik Special Program (PK) Surakarta, which consisted of six students. The instruments in this research are non-routine problems or tests, observation sheets, and interview guidelines. The questions validator in this research are two teachers and a Mathematics Education lecturer from the University of Muhammadiyah Surakarta. The data collection technique uses tests, observations, and interviews. The data analysis technique of research had carried out through three stages: data reduction, data presentation, and conclusion drawing. This study concluded that the student's metacognition of eighth grade in solving non-routine problems had not developed better. Only one student can ideally find the metacognition aspects of awareness, evaluation, and regulation. Compared to medium-capable students, students with high abilities can discover the metacognition aspects well. In comparison, students with low skills have not been able to find all indicators of metacognition. Based on the results, further research may discover students’ obstacles in implementing metacognition for mathematical problem-solving.

In recent years, ICT development has greatly affected the education sector. The development has provided many opportunities to innovate and improve the quality of education. Dynamic mathematics software is one of the learning media that is widely used in mathematics lessons. China has always wanted to be innovative by developing Hawgent Dynamic Mathematics software with more features than other dynamic mathematics software. This research aims to determine the effect of Hawgent Dynamic Mathematics software on mathematics achievement and analyze the advantages of Hawgent compared to other dynamic mathematics software. This research employed a meta-analysis approach by analyzing 28 empirical research articles published in both Chinese and foreign journals. There are 46 effect sizes with 4137 students from 2018 to 2021. Furthermore, the data was obtained using CMA software. The results showed that the effect size of Hawgent on mathematics achievement was 2.11 (P=0.000.1), within the very high category. Further analysis showed that the number of students did not affect Hawgent’s effect size. The effect of Hawgent at the senior high school level was greater than at the elementary and junior high school levels. Furthermore, Hawgent’s effect on geometry and algebra subjects was greater than any other subjects. This research can be useful as information on the development of dynamic mathematics software since many countries tend to use Geogebra and Geometric Sketchpad.

The research about Ordinary Differential Equation (ODE) has increased more widely since 1970. Therefore, several published articles in some journals can be found in some sources. This paper aims to provide an overview of the learning differential equation in higher education based on relevant literature. Therefore, we are interested in conducting a Systematic Literature Review (SLR) methodology from 24 articles generated from Top 5 Scopus Q1 according to SJR reported by Scimago Journal Country Rank in the subject area of education. The present study focuses on two aspects, namely: 1) the learning method of ODE that is proposed in the academic literature, and 2) the topic of ODE has been put forward and discussed in the academic literature. The systematic literature review found four methods of learning ODE (active learning, mathematical modelling, information, and technology communication, and geometric and qualitative solutions). Moreover, we also concluded that the several topics of ODE in the academic literature are 1) first order of ODE, 2) Euler method, 3) application to the problem (rate of change, population model, logistic generalized, and spring-mass), 4) second-order of ODE, and 5) system of ODE. The result of this study can provide a summary of existing literature and identify the weakness or gap to be investigated further in the following research related to the topic of ODE.

Critical Thinking (CT) ability is an essential skill needed in the 21st century. However, this skill is still under-explored by paying attention to the tendency of Learning Styles (LS) students when online learning is carried out. Therefore, this study aims to determine the differences in the improvement of students' CT abilities based on LS tendencies (visual, auditory, and kinesthetic) when online learning is carried out on algebraic function derivative application materials. Consisting of 4 essay questions given twice, before the sample in this study was a collection of CT, and LS ability scores of class XI science students in Langsa City, totaling 26 students. The researchers collected the data using an LS questionnaire of 30 statements and a written test of CT ability after online learning. Both instruments have been validated. The research method is a pre-experimental design with the type of one-group pretest-posttest. The results showed that (1) students had more dominant kinesthetic LS tendencies compared to visual and auditory LS; (2) students with visual LS have criteria for increasing critical thinking skills in the high category, while auditory and kinesthetic LS is in the medium category; (3) there is a significant difference in the acquisition of CT abilities between visual, auditory, and kinesthetic LS, where students with Visual LS outperform students with Auditory and kinesthetic LS; (4) there are differences in the improvement of CT abilities between students with visual, auditory, and kinesthetic styles in online learning. The improvement in CT ability of students with visual LS is greater than that of Auditory and kinesthetic LS.

Learning mathematics that can improve elementary school students' critical thinking skills is rarely done. Therefore, students' mathematical necessary thinking skills still need to improve. The realistic Mathematics Education (RME) learning model is expected to enhance mathematical critical thinking skills because of providing contextual problems to students. This study aims to determine the effect of the Realistic Mathematics Education (RME) learning model on students' critical thinking skills in mathematics. This research uses quasi-experimental research. The population in this study were students of class VI SDN 1 Kalikoa, Cirebon Regency. The sample selection in this study was carried out using a cluster random sampling technique to determine the experimental and control classes. In this case, two classes were selected: class VI A as the practical class and class VI B as the control class. The instrument for collecting data tests mathematical critical thinking skills on integer material. The results showed that the RME learning model is more effective than the direct learning model on students' critical thinking skills in mathematics. This is because the value of , and at a significance level of 5% and DK of 40, which means , so H0 was rejected, and H1 was accepted. The results of this study can be used as input for teachers and prospective teachers to improve themselves concerning the teaching that has been done and the student's critical thinking skills that have been achieved by paying attention to the right learning model to improve students' critical thinking skills in mathematics.

Students learn mathematics through practical applications without applying it. Consequently, the concept images and definitions that students offer do not match. This study examines the gap in mathematical ability between the concept images of professionals in mathematics education and students' concept images of content, including quadrilaterals. This study employed a qualitative approach with a hermeneutic phenomenology method. Sixty-two seventh-grade students were involved in conducting this study. Some instruments, such as quadrilateral-related tests and semi-structured interview questions, were used to collect the data. The results of quadrilateral-related tests and interviews revealed that most students with high mathematical ability, some with medium mathematical ability, and a small number with low mathematical ability have a concept image that matches the definition but cannot produce proof of the properties of a quadrilateral. In addition, a small number of students with high mathematical talents, some with medium mathematical abilities, and a large number of students with low mathematical abilities were unable to completely explain each rectangle's formal definition and properties. This indicates that there are some students whose concept image is low. So, several alternatives and effective mathematics learning should be implemented to facilitate students in enhancing students concept image.
