<![CDATA[This study was conducted with the primary aim of evaluating and deeply understanding students' abilities in solving mathematical problems, specifically focusing on Linear Equations and Inequalities with One Variable (SPLSV). A qualitative approach was chosen because it allows researchers to delve deeper into students' thought processes and how they approach given mathematical problems. Descriptive analysis was used to interpret data systematically and in detail, enabling researchers to identify specific patterns in test data and interviews. Adab Kesuma Bangsa Junior High School in Natar, South Lampung, was selected as the research site because it was considered representative of the student population being studied. A total of 32 students participated in this study, selected through Purposive Sampling method. The research instruments used included written tests and in-depth interviews. The main indicators focused on in this research were: (1) understanding of the problem, which measured how well students could identify and comprehend key elements of mathematical problems; (2) solution planning, which assessed students' ability to formulate effective strategies or steps to solve problems; (3) solution implementation, which observed to what extent students could apply their plans in practice and achieve correct solutions; and (4) re-evaluation, which evaluated students' ability to reflect on their processes and outcomes, identifying errors or areas for improvement. The research findings indicated that only a small proportion of students (21.5%) demonstrated high problem-solving abilities. Approximately 11.5% were at a moderate level, while the majority of students (67%) exhibited low problem-solving abilities. These findings provide valuable insights for educators and policymakers regarding the need for more effective educational interventions to enhance students' mathematical problem-solving abilities]]>

<![CDATA[Mathematics learning must be oriented towards achieving mathematical skills and shaping students' character. The nature of mathematics as the highest form of rationality, often results in the teacher's view that mathematics is only intended for cognitive development, but it is difficult to develop students' character. For this reason, the purpose of this research is to develop mathematics learning to improve students' cognitive abilities and character. This study uses an integrative literature review method by integrating ethnomathematical theory and project-based learning to build a theoretical framework for the Epsipo Learning Strategy (Ethnomathematics-Project-based Learning). The epsipo strategy is basically an effort that can be made to teach mathematics through a project with a cultural context. The project-based learning model has contributed to realizing meaningful mathematics learning, but it lacks value instillation. The ethnomathematics initiated by D'Ambrosio is rich in moral and social values. The two theories complement each other with their own advantages. Through the implementation of the Epsipo strategy, it is hoped that students will have the knowledge and ability to think mathematically and develop their character. It is hoped that through this strategy, mathematics learning is not only oriented towards achieving cognitive aspects but also to strengthen students' character.]]>

<![CDATA[Critical thinking skills can encourage and develop students' learning to observe, find, and solve problems. Critical thinking skills can encourage and develop students' learning to observe, find, and solve problems. Thinking skills can be improved to improve the learning activities provided by the teacher. It is still challenging to improve critical thinking skills in student learning. Students tend to be passive in learning, often without the same thinking skills as the teacher, resulting in less development of critical thinking skills. The purpose of this study is to identify Treffinger-based scaffolding. This type of research is a meta-analysis. This article examines several international and national journals regarding Treffinger, Scaffolding, and critical thinking. The scientific studies included in this study were selected according to the criteria. This article is a study by several researchers regarding scaffolding and its effect on students' critical thinking skills and provides several recommendations for teachers and researchers regarding scaffolding and learning models. The result of the research is that scaffolding will be reduced or even eliminated in learning after students get a sufficient and correct understanding. Thus, Treffinger-based scaffolding can benefit students in critical thinking learning. Can Key Scaffolding help students solve problems and improve students' critical thinking skills. Treffinger's learning model can make students solve problems with ID and ideas chosen by students.]]>
