Ethnomathematics can empirically improve the cognitive abilities of students in elementary and secondary schools. However, in undergraduate study, there are still limited studies on integrating ethnomathematics in learning resources. This study aims to apply interpolation in modelling polynomial functions and integral volume on the shape of Buginese and Makassarese traditional foods. Furthermore, it can be used by students as relevant learning resources regarding interpolation and the concept of volume of solid of revolution (VOSR). This is a qualitative study using an ethnographic approach. The data were collected through observations to obtain general information, interviews with informants to find out food-making techniques, and documentation to obtain physical models of each type of food. Data Analysis Techniques consist of the domain analysis to obtain an overview of Buginese and Makassarese traditional foods and the taxonomic analysis to categorize mathematical concepts obtained from the modeling and simulation. The result of this research reveals that lammang is suitable with the slabs. It can be represented as constant functions that revolved around the x-axis or the y-axis. While paso, bolu cukke, and cantik manis as well as barongko batara, Putu, and cucuru can be outlined in linear functions rotating about the x-axis, y-axis, or others fixed-line. They meet the criteria of the disks method. However, they are described in the function of polynomials of n-degree. The use of washers can be described in the model of blundered and sarang semut with a hole in the middle caused by the intersection of two curves rotated about the x-axis or the y-axis. For shells, the model can be applied to determine the cover volume of the cover of pisang ijo flour and onde-onde. Thus, all types of traditional foods in this study can be appropriate objects for a learning resource in modelling the VOSR.

One goal of learning mathematics is to foster students’ critical thinking skills, but this has not been realized well in Indonesia. This study aims to produce a learning trajectory that can help students grow their critical thinking skills in studying quadrilaterals using the Burongko cake context. This study uses a design research method that comprises three stages, namely (1) preliminary design, (2) experimental design, and (3) retrospective analysis. This research was conducted at Madrasah Tsanawiyah As’adiyyah Bontouse with 25 students, nine males and 16 females of class VIII B. The results showed that this learning trajectory could improve students’ understanding of learning quadrilaterals with ease and fun because mathematical concepts are associated with students’ daily habits. The resulting learning trajectory is relevant to indicators of critical thinking skills, including interpretation, analysis, evaluation, and decision making. It was found that there was no significant difference in critical thinking skills between students who had high mathematical abilities and low mathematical abilities. Subjects with high mathematical abilities could carry out critical thinking processes to solve problems much better than subjects with low mathematical abilities. The results provide information about the use of local Bugis culture as a context of learning mathematics to improve students’ critical thinking.

The purpose of this study is to explain the doctrine expectations of learning mathematics. Data was collected through testing, interviews, and documentation. Researchers have designed a virtual learning trajectory (HLT) based on examining the obstacles students face when learning mathematics. Next, a didactic design was developed from HLT. The method of doctrine was implemented, and the results showed that the situation of the three principles expected by researchers was the doctrine of scaffolding strategy. When determining values that correspond to a pattern of numbers, researchers want to learn lessons and provide instructions in the form of education to solve problems. The researcher's expectation of giving other examples of arithmetic progressions when choosing a definition and the arithmetic progression examples help students better understand collaborative learning. The value of the nth term and the sum of the first n math terms are sent to each shirt to confirm the work and interact directly.

Errors in problem solving indicate that there are parts of the cognitive structure that are problematic, either because they are disorganized, disconnected or experiencing cognitive holes. thinking This research uses a qualitative approach. The data analysis technique used refers to the Miles and Huberman analysis model, namely data reduction, data presentation and finally drawing conclusions. The results showed that the three subjects studied were only S1 subjects who were able to answer all the questions given correctly without going through the defragmenting process, this was because the problem-solving thinking structure of the questions was classified as good, this success was supported by the level of cognitive understanding of the prerequisite material for the questions. good. While on the subject of S2, even though the conclusions of the answers already look correct, in one of the questions, it appears that there is an error in thinking which is categorized as pseudo, this error occurs because of the tendency to only pursue similarity questions and do not emphasize understanding mathematical concepts. The defragmenting efforts given are in the form of cognitive conflict interventions, scaffoldingâ€“restructuring and scaffolding explaning. While on the subject of S3, the low literacy ability in reading the test questions, as well as understanding the concept of the prerequisite material for the questions, causes errors at all stages of problem solving. The defragmenting efforts given are scaffolding-explaning intervention, scaffolding restructuring, cognitive conflict, scaffolding-review, disequilibration. The lack of knowledge about the prerequisite material so that more emphasis is placed on providing scaffolding-explaning.

This research is focused on exploring the concepts of geometry and algebra on the equipment used in Konjo ethnic weddings which are categorized in the aspects of artistic tools, sandan, boards and food. This research is a qualitative research with an ethnographic approach whose stages include determining the scope, determining and interviewing informants, documenting and recording, domain analysis, taxonomic analysis and ethnographic writing. Based on the exploration results it is found that the observed customary equipment can be modeled into a relationship between polynomial functions, such as the relationship of two parallel lines and two perpendicular lines in the balli' and kanre anak, a quadratic function rotated about the x-axis represents the gandrang pannahan model. The relationships of constant, linear and quadratic functions which are rotated about the y-axis produce the form of the gandrang jong. Furthermore, the concept of geometry can also be explored in the songkok recca as a sandan requirement whose surface is elliptical and the volume can be approximated using the concept of volume calculation using the slab approach. Whereas in the food aspect, there are beng-beng as dumplings for cucuru which can be represented as a constant function which is rotated around the x-axis. In the process of making the equipment explored it shows the ability, skills and mathematical activities in the form of counting, designing, measuring, locating and explaining. Mathematical concepts identified in customary equipment can be used as contextual learning resources in learning mathematics in formal education.

The low ability of students to understand and transform the concept of reflection to solve everyday problems is the main problem with learning mathematics because the implementation of learning mathematics is mechanical. Mathematics is taught by conveying formulas practically without linking them to students' daily activities. For this reason, this study aims to design a reflection learning trajectory in the context of the Lipa Sabbe Bunga Caramming motif as a starting point in learning to help students understand reflection material for solving everyday problems. The method used in this study is design research, which consists of three stages: preliminary design, design trials, and retrospective analysis. The subjects of this study were 23 students in class VIII-A of SMP Negeri 1 Tanasitolo. The instruments used in this study were student activity sheets (LAS), learning achievement tests, and interview guidelines. Student activity data during learning were analyzed retrospectively, and learning outcomes data were analyzed descriptively. The results of this study found that the learning trajectory of transformation geometry using the context of the lipa sabbe bunga caramming motif has four learning stages: (1) informal; (2) modes of; (3) modes of; and (4) formal. The learning stages can easily increase students' understanding of the concept of reflection. In the learning process, mathematical concepts are connected with daily habits, so students are enthusiastic and active in the learning process. This learning trajectory can assist teachers in optimizing learning so that students can easily understand the concept of reflection, equip them with critical thinking skills, and shape their character (cooperation, empathy, respect for others, awareness of social problems, a social spirit, and responsibility).
