Derivatives are one of the objects of calculus that is difficult for students to learn. The purpose of this study was to describe the cognitive processes of students in understanding the application of derivatives. This is a qualitative research involving one subject with the initials L. The main instrument of this research is the researcher who is guided by an assignment sheet and an interview guide. Data collection was carried out through task-based interviews. To get complete and accurate data recorded through audiovisual. Data were analyzed descriptively through genetic decomposition based on APOS (action-process-object-schema) theory. The results of this study are that L can coordinate the process-object of all the properties of a given function, with adjacent or overlapping intervals in all h domains so that a mature scheme of function graph sketches is formed. So that an accurate function graph sketch is obtained. The conclusion is that L's cognitive process of applying derivatives is at a high level. It's a trance level.

The purpose of this study was to describe the achievement of the triangular principle of junior high school students through YouTube-assisted learning during the COVID-19 pandemic. It is exploratory research. The subjects of this study were middle school students in Bengkulu City, Indonesia. We conducted task-based interviews with twenty-one people. The data from the completion of the task was analyzed early to determine their level of thinking. It was using its genetic decomposition. We classified them into five levels of schema development. We selected students who were at the trance level for further in-depth interviews. We use audio-visual recorders to get complete and accurate data. Data were analyzed by applying qualitative data analysis techniques. The results of this study were 19% of the research subjects were at the intra level, 33% were at the semi-inter level, 33% were at the inter level, and 10% of the subjects were at the inter level, and only one person who was at the trance level (= 5%). The conclusion of this study is that students who are at the highest level are able to build relationships between actions, processes, objects, and previous schemas so that a mature schema is formed about the area of the triangle.

Mathematics learning still tends to be structuralistic and mechanistic. It resulted in students' difficulties and errors in understanding mathematical concepts and principles. Whereas mathematics is a human activity that is always in contact with their culture. One of the cultures that becomes the starting point for learning mathematics is a traditional house, such as the “Rumah Tuo”. The purpose of this study was to describe the mathematical activity at the Rumah Tuo. This type of research is a qualitative-research with an ethnographic approach. The research instrument used in the form of observation, interviews, and documentation. The results of this study are that there are mathematical activities carried out at Rumah Tuo, namely counting activities using Gantang Biheh, measuring activities in making poles in the form of a 16-sided prism, and designing traditional houses in such a way that they can be shaped like ancient means of transportation, namely ships. The conclusion of this research is that there are three mathematical activities through the “Rumah Tuo” culture, namely measuring, designing and calculating.

Limit was to basic concept of derivative. The results of previous research found that learners have obstacles in understanding the limit function, consequently, the occurrence of difficulties and mistakes learners understand the concept and derived principles. This study aims to determine the obstacles of learners in applying derived properties. The approach of this research is qualitative by applying task-based interview with subject of 10 students selected by certain condition from 70 students in Mathematics Education Study Program of University of Bengkulu. The researcher is the main instrument in this research which is guided by the interview sheet and duty sheet. Data analysis was performed by genetic decomposition analysis. The results of this study indicate that the barriers of learners in applying analytic concepts and properties analytically include, the tangent line almost parallel to the y-axis, the break point (cusp) at x = -4, the second derivative, the extreme point, the emergence of contradictions, asymptotes flat, and do not understand conceptually. To overcome the obstacles of learners in understanding the concept and the nature of derivatives and its application, it is suggested to apply the mathematics learning model based on the extended triad++.

Critical thinking and political literacy are essential competencies in 21st-century education; however, they are often developed separately in school learning. This study investigates the relationship between mathematical critical thinking ability and students’ political literacy at the senior high school level. Using a quantitative correlational design, data were collected from 80 eleventh-grade students selected through stratified random sampling from three public high schools in Yogyakarta City. The instruments consisted of a mathematical critical thinking test and a political literacy questionnaire, both of which demonstrated acceptable validity and reliability. Data were analyzed using the Pearson Product–Moment correlation. The results revealed a significant positive correlation between mathematical critical thinking and political literacy (r = 0.58, p < 0.01), indicating that students with stronger mathematical reasoning tend to exhibit higher political literacy, including a better understanding of democratic values and more rational civic attitudes. These findings demonstrate that mathematical critical thinking contributes meaningfully to students’ political literacy. The study highlights the importance of integrating socio-political contexts into mathematics instruction as an interdisciplinary approach to fostering analytical and responsible citizenship in a democratic society.
