This study was conducted with the aim of knowing the numeracy errors of high school students in working on logarithm problems on the Minimum Competency Assessment (AKM). The method used in this research is a qualitative approach. The research instrument is a numeracy test in the form of multiple choice questions, short form, descriptions with three indicators and guided interviews. The research subjects consisted of 6 grade 10th subjects at one of the public high schools in Bandung. The results showed that students' numeracy skills were still relatively low. A total of 5 students were categorized as low and 1 subject was categorized as medium. The lowest score obtained was 27 and the highest was 44. Based on the results of the interview, it was found that students were lazy to read the questions because the questions were so long, the processing time went so fast, and had a low understanding of the concept of logarithm material, so they had difficulty in overcoming he numeracy problems of the Minimum Competency Assessment (AKM).

Mathematical literacy skills are important to answer various problems systematically by using facts and information. This skill is important to have, especially for students. With this skill, students will be able to face today's increasingly complex developments. This research discusses the mathematical literacy skills of class VII students at one of the MTsN in Bima, West Nusa Tenggara. This research uses a descriptive qualitative approach. Data was collected through a written test with four essay questions on the material "three-dimensional shapes" especially on cubes and blocks. The questions are created based on literacy indicators of planning mathematical situations, using mathematical concepts, and interpreting mathematical results. The research results show that the indicators for planning mathematical situations and interpreting mathematical results obtained scores of 35.71 and 31.5, so they are in the low category. Meanwhile, the indicator using concepts, facts, procedures, and reasoning is quite high, 80.80. However, overall it was found that students' mathematical literacy abilities were still relatively low, so to maximize mathematics learning, efforts were needed to improve mathematical literacy abilities.

algebra is a fundamental topic in mathematics, particularly emphasized during the junior high school years as an essential subject. In the context of linear equations in one variable, students often struggle with obstacles in basic algebra including variable degrees, variable concepts, coefficients, and constants. However, proficiency in understanding algebraic concepts is significantly lower compared to other areas and skills. As a consequence, this research aimed to explore students' learning obstacles in solving linear equations in one variable in secondary schools based on mathematical proficiency. The research design using the hermeneutic phenomenological approach. This research is a framework of the Didactical Design Research (DDR). DDR is based on two paradigms: the interpretive and the critical paradigms, and it aims to empower students in the context of generating new knowledge as justified true belief. In this study, the researcher delves into the interpretive paradigm. The research subjects involved 46 seventh-grade secondary school students from five different schools across four distinct provinces in Indonesia. The instruments used were test and non-test. The test was done by giving a diagnostic test about linear equation problems, while interviews used the non-test technique. The data collected were analyzed using the Miles and Huberman model, namely data reduction, data presentation, and drawing conclusions. The study findings revealed that students met three types of obstacles in linear equation material, namely ontogenic obstacle, epistemological obstacle and didactical obstacle. However, students faced limited knowledge to solve mathematics problems in one variable, for instance, solving mathematical operations and making modelling problems from real situations deal with linear equations in one variable. Therefore, future research can focus on developing a Didactical Design to reduce this obstacle.

Indonesian students perform inadequately in the International Mathematics and Science Study (TIMSS). Before utilising National Examination (UN) questions as measures of learning accomplishment, evaluating them within the context of a theoretical framework for mathematics education is imperative. They analyse student mathematical proficiency using TIMSS and National Examination questions and apply pedagogic anthropological theory, particularly praxeology. This study employed content analysis as a qualitative research method. An algebraic analysis was conducted using the praxeological technique. This entails evaluating concerns, approaches, and technological and theoretical alternatives (logo block). The results indicate that the TIMSS questions require careful consideration and analytical thinking. In contrast, National Examination questions restrict students' cognitive capacities to acquire knowledge on specific topics. The placement of national test question types will be determined based on analytical data. Indonesian students must enhance their arithmetic scores, which consistently remain low. To promote the growth of a highly skilled labour market, the government must comprehend the intricacies involved. Teachers should customise their classes to align with the individual learning objectives of each student.

This study aims to understand how pre-service mathematics teachers conduct prospective analyses comprehensively. A qualitative research method with a case study design was used. The participant was Mrs N, a pre-service mathematics teacher who conducted research using DDR methodology in a grade 9 junior high school in Sindang, Majalengka, involving 48 students. Data were collected by analyzing empirical evidence from Mrs. N's prospective analysis process by uncovering the various stages of a prospective analysis. An iterative approach was used to analyze the data by refining the research questions through discussions and regular meetings with Mrs. N. The process ensured adaptability to new insights and understandings from the empirical data. Our findings reveal that the teacher draws upon fundamental philosophical principles from didactical design research, including hermeneutics, phenomenology, and ethnomethodology. By embracing these approaches, the teacher gains valuable insights into conducting research within an interpretive paradigm, allowing for a deeper exploration of the meaning of concepts, the purpose of learning, and the cultural influences that shape the educational process. Additionally, our study sheds light on the emergence of transpositional didactics theory as the prospective teacher delves into understanding the meaning of the geometrics transformation concept.
