This study aims to produce a learning design for flat-sided geometry based on Rejang Lebong ethnomathematics to improve students' mathematical problem-solving skills that are valid, practical, and effective. It is motivated by the low ability to solve students’ mathematical problems. Mathematics learning carried out in schools should involve students actively. The research procedure is guided by the Plomp development design. The development model studied by Plomp is the initial investigation, development, prototyping, and research phases. In the initial investigation phase, the implementation of needs, curriculum, concept, and student analyses was implemented. In the prototype development phase, formative evaluation consists of self-evaluation, one-on-one evaluation, one-on-one evaluation, small group evaluation, and testing. Meanwhile, at the time of its application, it was tested on students of class VIII SMP to see the learning outcomes of the learning problem-solving abilities. Based on the development that has been carried out, it is obtained that the learning design of flat-sided geometry based on the Rejang Lebong ethnomathematics in the form of HLT, teacher's books, and books for class VIII SMP students are valid, practical, and effective.

All students from every level of education should have excellent and adequate creative thinking, but in Indonesia students’ creative thinking is still low. There are a lot of factors that affect creative thinking, such as learning styles. This study aimed to investigate the comparison of students’ creative thinking based on study level and learning styles, gender, and the combination of the three to determine which factor or type of students needs to be improved. This research uses a statistics descriptive method. The participants of this study were 38 senior high school students, 35 students of the teacher professional program (PPG), 24 undergraduate students (S1), and 12 master program students (S2). The instrument used in this study is a learning styles Learning style test to determine the student’s learning styles and creative thinking questions to classify the students. The results of this study are i) Students’ level of study does not determine their creativity level; ii) Based on gender, female is more creative than a man; iii) Based on the learning style, visual students is the best, followed by kinesthetic and auditory in order; and iv) Merdeka curriculum of Indonesia, nowadays, is essential to make the best learning process to improve students’ creative thinking.

Berdasarkan hasil analisis pendahuluan yang dilaksanakan di MTs Lembah Gumanti, diperoleh informasi bahwa kemampuan komunikasi matematis peserta didik belum tercapai secara optimal. Salah satu faktor penyebabnya adalah belum tersedianya perangkat pembelajaran yang dapat memfasilitasi peserta didik untuk meningkatkan kemampuan komunikasi matematis peserta didik. Hal tersebutlah yang mendasari untuk melakukan pengembangan perangkat pembelajaran matematika berupa Rencana Pelaksanan Pembelajaran (RPP) dan Lembar Kerja Peserta didik (LKPD) berbasis Penemuan terbimbing yang memberikan kesempatan kepada peserta didik untuk dapat menemukan sendiri konsep dari materi yang dipelajari sehingga peserta didik dapat mengkomunikasikan pengetahuan tersebut baik secara lisan maupun tulisan. Data dikumpulkan melalui observasi, dokumentasi, angket, wawancara, dan tes kemampuan komukasi matematis. Subjek penelitian adalah peserta didik kelas VIII MTs/SMP Lembah Gumanti. Jenis penelitian ini adalah penelitian pengembangan menggunakan model Plomp yang terdiri dari fase preliminary research berupa analisis kebutuhan, analisis peserta didik, analisis kurikulum, dan analisis konsep. Pada fase prototype dilakukan perancangan produk yaitu RPP dan LKPD berbasis penemuan terbimbing, kemudian dilakukan evaluasi formatif untuk menentukan kevalidan dan kepraktisan produk. Pada fase asessment dilakukan penilaian uji praktikalitas dan uji efektivitas. Tujuan dari penelitian ini diharapkan dapat memperoleh perangkat pembelajaran matematika berbasis penemuan terbimbing untuk kelas VIII MTs/SMP yang memiliki karakteristik valid, praktis dan efektif.

Ethnomathematics integrates cultural contexts into mathematical learning, enriching students' comprehension of mathematical concepts and their applications. This study explores the embodiment of ethnomathematical concepts within the architecture and ornamentation of Rumah Gadang in Luhak Tanah Datar, a traditional dwelling renowned for its intricate designs. Employing a qualitative research methodology, this investigation utilizes interviews, participatory observation, and document analysis to examine the contributions of two craftsmen. The primary objective is to elucidate the mathematical principles manifest in the structural and decorative elements of Rumah Gadang, with a focus on identifying specific mathematical ideas and concepts that are applicable to educational settings. Findings reveal that the architecture and decorations of Rumah Gadang incorporate various mathematical concepts, including counting, measuring, locating, designing, playing, and explaining, which are expressed through numbers, shapes, lines, geometric transformations, trigonometry, angles, and symmetry. This research not only highlights the presence of intricate mathematical ideas in traditional architecture but also suggests the potential of these findings to serve as valuable educational resources in teaching mathematics. Additionally, these insights provide a foundation for further ethnomathematical studies related to Rumah Gadang.
