Critical thinking is a very important skill for students to address the obstacles faced in this day and age. However, a number of studies show that Indonesian students have low levels of critical thinking, especially in mathematics. The problem-based learning (PBL) model is one method that can be used to overcome this problem. The Systematic Literature Review (SLR) method was used in this study to evaluate the problem-based learning (PBL) approach on improving critical thinking skills. Research published in the time span of 2018 to 2024 with related keywords were investigated. The analysis of 13 articles showed that the use of PBL improved students' critical thinking skills, especially in junior high school. These findings suggest that PBL should be applied as well as possible in the mathematics learning process to develop and improve students' critical thinking skills in Indonesia. Students' inability to explore and develop new ideas is a major obstacle in the application of PBL.

This study aims to determine the application of the peer tutor method to the mathematics learning process of 5 deaf students in class X SMALB Negeri Slawi. The method used is the descriptive method. The data collection is done by testing, observation, and documentation. Data analysis was carried out by data reduction, presentation, and conclusion, which is the model of Miles and Huberman. Based on the results of data analysis, it can be concluded that peer tutors provide convenience for deaf students with below-average abilities in working on math problems. This is because deaf students get direction and assistance from deaf students who already understand and act as tutors so they can solve math problems. The application of the peer tutor method facilitates the learning process of deaf students. Students communicate with each other to assist, increase learning activity, and solve problems together it can affect the completeness of the learning outcomes of deaf students. In the learning process, peer tutors can be used as an alternatively appropriate and effective learning method, especially for deaf students.

Mastering algebraic concepts and skills has been one of the demands in the Indonesian curriculum for the past few decades. Teaching algebraic concepts and skills is one of the materials taught from the junior high school to university level. Therefore, it is mandatory for pre service mathematics teacher students to master and even fluently use algebraic concepts in order to develop students' algebraic thinking skills. Thus, this study aims to understand and obtain a description of students' algebraic thinking abilities and misconceptions in solving problems. This research using descriptive qualitative. Analysis was conducted using tests and in-depth interviews with students who had taken linear algebra courses in semester 3 of the Mathematics Education Study Program at private university in NTT. Student’s algebraic thinking skills in solving problems were analyzed using Kieran's (2004) indicators consisting of: generational activities, transformational activities, and global meta-level activities. The results of the research show that…. In generational activities, students in the low, medium, and high categories have misconceptions. In transformational activities and global meta-level activities, misconceptions are only carried out by low category students.

In learning mathematics, reflective thinking is often overlooked due to an excessive emphasis on final results, which causes students to struggle in evaluating and reconstructing their problem-solving processes. Reflective thinking skills are necessary for students to solve problems, including numeracy. This study adopts a qualitative approach, focusing on the problem-solving process of two seventh-grade students with a Dependent Field (DF) cognitive style and similar initial mathematical abilities. Data were collected through the Group Embedded Figures Test, in-depth interviews, and initial mathematical and reflective thinking ability tests. Based on the research results, DF students couldn't analyze arguments from various perspectives and see if there were deeper implications. This finding reflects the characteristics of DF, who don't perform the 'result in context' process, leading to a lack of ability to understand, interpret, and use numerical results in concrete/situational contexts. This also includes the ability to relate numbers to real-world situations, make appropriate interpretations, and take suitable actions based on those numerical results. The results of this study can serve as a foundation for designing differentiated instruction that emphasizes the development of reflective thinking skills, particularly in numeracy, through approaches involving technology, models, pedagogy, or other learning strategies.

The differences in the development of students' thinking levels, especially in adolescence, impact the way they perceive problems. Contextual learning with ethnomathematics can provide opportunities for students to develop problem-solving abilities based on their level of thinking. This study examined the contextual learning with ethnomathematics to enhance problem-solving abilities based on thinking levels.This experimental research was conducted by posttest only control group design. The participants of this research were 60 students at a junior high school in Gowa Regency, South Sulawesi Province.Data were collected using observation sheets to determine local cultural characters that appeared at the time of treatment. The thinking level category uses the group assessment for logical thinking (GALT) test. The students' mathematical problem-solving abilities use the curved side space material to suit the local cultural context. The data analysis technique used descriptive statistics and covariance analysis (ANCOVA). This study results indicate that contextual learning with ethnomathematics influences problem-solving abilities based on the level of thinking. Furthermore, local cultural characters appear in each category of students' thinking levels. Students with formal thinking levels have better problem-solving abilities than transitional and concrete thinking levels. Contextual learning with ethnomathematics fosters problem-solving abilities based on the thinking levels.

In educational settings, reflective thinking is often overlooked, with an excessive emphasis on final answers, resulting in students needing more ability to evaluate and reconstruct their problem-solving processes. The ability for reflective thinking is required by students in solving problems, including numerical problems. This study uses a qualitative approach to focus on field-independent students' numerical problem-solving processes. The data collection technique begins by administering the Group Embedded Figures Test (GEFT), a valid and reliable numeracy problem instrument, and conducting in-depth interviews. Two students with similar initial mathematical abilities and field-independent cognitive styles were selected as research subjects. Findings reveal that these students face challenges such as lengthy problem descriptions and a lack of confidence but gradually develop strategies, emphasizing repeated problem analysis, concept interconnections, and error awareness. Researcher-provided scaffolding facilitates critical reflection, enabling the construction of new ideas. These results have practical implications for teachers, suggesting the need to design lessons that cater to diverse cognitive styles, providing more complex problems to field-independent students to enhance their problem-solving skills.

Cervical cancer is one type of disease that has the highest risk of death in the female population in Indonesia. Almost 95% of cervical cancer in women is caused by Human Papillomavirus (HPV) infection, which is common in women of reproductive age. In this study, a mathematical model is discussed for the case of the spread of the HPV virus to become pre-cancerous with immunotheraphy treatment. This research was conducted by building a mathematical model, analyzing the equilibrium point, and interpreting the mathematical model with numerical simulations using Maple software. This study divides the population into 5 sub-populations including susceptible (S), infected (I), precancer (P), and treatment (T) sub-populations. From the model formed, the disease-free equilibrium point and endemic equilibrium point are obtained as well as the basic reproduction number . The disease-free equilibrium point is locally asymptotically stable when and the endemic equilibrium point is locally asymptotically stable when . Based on the results of numerical simulation analysis, it is obtained that the immunotheraphy treatment is greatly affects on individual recovery.
