The data obtained are qualitative data with data sourced from observation and participant observation (fieldwork), interview and questioner, document and text, impression, and the reaction of the researcher. The technique of validity was using triangulation. The result of the research showed that from several kinds of Tapis cloths: 1) They had a philosophical sense on every Tapis motif related to the Lampung people's existence. 2) Two activities exist in Tapis Lampung that was measuring activity and counting activity. 3) Mathematical concepts on Lampung filters include One-dimensional geometry found in the star's motifs that applied the line concept. The two-dimensional geometries were triangles, rhombus, and elliptical rectangles derived from Tapis Pucuk Rebung, swaying headers, stylish headlines, and geometric motifs. Transformation Geometry concept of Reflection and Rotation was on mangosteen flower and leafflower. Dilatation was on the rhombus motif. The translation was on the motives of humans and riding animals.<br><br></p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">Penelitian ini bertujuan untuk mengetahui apa saja aktivitas etnomatematika pada kain tapis yang dapat dijadikan sebagai sumber belajar matematika.

The method used in this study is Quasy Experimental Design. A random sampling technique took a sample of 60 students. Data collection is carried out with written tests and documentation. The method uses an analysis of variance (ANOVA). Hypothesis testing uses two different path tests of variance analysis in cells. The results showed that there were mixed effects of each learning model on students' mathematical literacy abilities. There was no influence between female and male gender on students' mathematical literacy abilities. There was no interaction between learning models and gender differences in students' mathematical literacy abilities. The teacher must strive to improve the mathematical literacy skills of middle school students so that students are more motivated to learn.</p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran <em>MASTER (Motivating, Acquiring, Searching, Triggering, Exhibiting, and Reflecting)</em>terhadap literasi matematis ditinjau dari perbedaan gender.

The type of this research is a quasi-experimental design with "respondent's pretest-posttest control design," the population in this research were all eighth-grade students of SMP N 7 Kotabumi. The sampling technique used random classes where VIII H as experimental class I, class VIII A as experimental class II, and class VIII E as the control class. The test instrument used was a description test. Based on the results of data processing using the ANAVA test, N-Gain data was obtained, , it means &nbsp;was rejected. It means that there was an influence of the Advanced Organizer learning model assisted with didactic design modules to increase understanding of mathematical concepts of students. The test continued with the Scheffe' analysis with acceptance , as well as denials &nbsp;and. Based on the results of the trial, it concluded that the Advanced Organizer learning model with didactic design modules is better than conventional learning models. However, the Advance Organizer learning model with instructional design modules is as good as the Advanced Organizer learning model.</p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran&nbsp;<em>Advance Organizer&nbsp;</em>terhadap pemahaman konsep matematis berbantuan modul desain didaktis persamaan garis lurus SMP kelas VIII.

Leveling the mental model of students is one way in which a teacher can review the extent to which students understand based on their respective levels. The purpose of this study was to describe the six degrees of student's mental models in understanding the concept of using the Pythagoras theorem in junior high school students. The method used in this study is a qualitative research method. The subjects in this study amounted to 61 students who were a combination of 30 students of class VIII A and 31 students of class VIII B. The two classes of subjects were taken so that the six levels of the mental model were founded. The sixty-one items test questions were given. Each of the representatives of mental models who found the criteria was selected, namely two students to be interviewed so that 12 students were interview respondents. To ensure the validity of the data, researchers analyzed the data in two ways, namely data source triangulation and method triangulation. The results of the study showed a description of each level of the student's mental model in understanding the concept of using the Pythagoras theorem.</p> <p style="text-align: justify;">&nbsp;</p> <p style="text-align: justify;">Suatudomain belajar, pemahaman merupakan prasyaratan mutlak untuk meningkatkankemampuankognitif.&nbsp; Pelevelan model mental siswa merupakan salah satu cara dimana seorang pengajar dapat meninjau sejauh manakah pemahaman siswa berdasarkan tingkatan masing – masing. Tujuan penelitian ini adalah untuk mendeskripsikan enam level model mental siswa dalam memahami konsep penggunaan teorema pythagoras pada siswa SMP. Metode yang digunakan dalam penelitian ini adalah metode penelitian kualitatif. Subjek dalam penelitian ini berjumlah 61 siswa yang merupakan gabungan dari 30 siswa kelas VIII A dan 31 siswa kelas VIII B. Dua kelas subjek tersebut diambil agar terpenuhi keenam level model mental. Keenam puluh satu subjek tersebut diberikan soal tes, kemudian dipilih masing – masing dari perwakilan model mental yang telah memenuhi kriteria yaitu 2 siswa untuk diwawancarai. Sehingga terdapat 12 siswa yang menjadi respondenwawancara. Untuk memastikan kevalidan data, peneliti menganalisis data dengan dua cara yaitu triangulasi sumber data dan triangulasi metode.
