This research is based on the absence of teaching materials about the concept of geometry that is able to facilitate the students connecting the culture, especially tembe nggoli which is one of the traditional woven cloth of mbojo-NTB with the concept of mathematics. Ethnomathematics is a mathematical bridge with culture, and ethnography recognizes the different ways of doing mathematics in community activities. The result of this study is to produce teaching materials in the form of students' worksheets. The method used is design research which includes: (1) preliminary design, in this phase is made Hypothetical Learning Trajectory (HLT); (2) experiments, in this phase existing designs are tested to students; (3) retrospective analysis, in this phase the researchers compare the HLT with the actual student learning process. The results of this research showed that tasks which were presented in teaching materials by considering learning obstacle and preliminary study able to facilitate students to define the properties of triangles based on their angle.

Preliminary Study

<p>Penelitian ini dilatarbelakangi oleh rendahnya kemampuan penalaran matematis siswa SMP pada materi geometri. Metode penelitian yang digunakan adalah penelitian desain didaktis (<em>didactial</em> <em>design research</em>).  Penelitian diawali dengan studi pendahuluan untuk mendapatkan data kesulitan belajar (<em>learning obstacle</em>) yang dilaksanakan di SMP Negeri 29 Bandung kelas IXE sebanyak 35 orang, SMA Negeri 1 Lembang kelas XI IPA2 sebanyak 41 orang, dan STKIP Siliwangi Bandung mahasiswa semester VI sebanyak 49 orang pada tahun pelajaran 2011/2012 semester genap. Selanjutnya, dikembangkan desain didaktis yang diujicobakan terbatas kepada 30 siswa kelas VIII B SMP Assalam Bandung. Dari uji coba terbatas dilakukan analisis untuk menyusun desain didaktis revisi. Hasil dari penelitian ini diantaranya perangkat pembelajaran yang digunakan pada pembelajaran sebelum menggunakan desain didaktis belum dapat menggali kemampuan penalaran matematis, desain didaktis penalaran matematis yang dikembangkan dapat memperkecil <em>gap</em> yang dihadapi siswa, dan siswa memberikan tanggapan positif terhadap desain didaktis yang dikembangkan.<strong></strong></p><p>The background of this research was the lack of junior high school students’ mathematical reasoning in geometry.

Local Instruction Theory

The purpose of this research is to develop local instruction theory on triangular and quadrilateral material and examine the improvement of mathematical representation ability by using local instruction theory. The method used in this research is design research method which includes three stages, namely: preliminary design, design experiment and retrospective analysis. The instruments in this study were in the form of tests and non-tests, where the tests used were aimed to determine the improvement of students' mathematical representation ability while non-tests such as interviews and observations were used to develop the local instruction theory. Subjects in this study were 40 junior high school students. The final result of this research is the development of local instruction theory teaching materials that can be used by the teacher to be used as a guide in teaching and the ability of students' mathematical representation in triangular and quadrilateral material is sufficiently increased

Teaching materials are said to be practical if the practitioners or the experts state that the developed teaching materials can be applied in the research. The purpose of this research is to reveal the practicality of redox e-modules and GDL-based electrochemical cells for XII grade of high school students. This research is a continuation of educational design research with the Plomp development model at the prototyping stage, this research was conducted at SMAN 1 Lintau Buo Utara. The data were analyzed with the Aiken V formula. The results of one-to-one evaluation showed that the e-module uses clear fonts, covers and attractive designs, the language used is easy to understand, the presentation of coherent material, videos and animations can help students to understand the material. The results of the analysis on the average Aiken V formula obtained a V value of 0.88 at the small group stage and 0.86 at the high category field test stage. This data is evidenced by the ability of students to answer questions on the e-module by 90.5 percent with a very high category. Based on the data analysis, it is concluded that the e-module redox and electrochemical cells based on GDL are practically used in the learning process with a high practicality category.

Geometry is an essential subject for students. However, geometry, especially the cone, remains a challenging material for students. Besides, we need the proper media and context for learning mathematics on cone material. This research aims to develop a learning trajectory that utilizes the Megono Gunungan tradition as a context in the learning process using the Indonesian Realistic Mathematics Education (PMRI) approach. The research method used is Design Research, which consists of three phases of the study: preliminary design, experimental design, and retrospective study. This study's outcome is designing a learning trajectory on cone material using the Megono Gunungan tradition. This learning trajectory comprises four activities, including observing the interactive video of the Megono Gunungan tradition to discover cone elements, finding the concept surface area of a cone using origami paper, and grasping the cone concept volume with magic seeds, and solving contextual problems related to the cone. Studies have shown that using the Megono Gunungan context could help students improve their understanding of the cone concept. Furthermore, this study hoped could be an inspiration for exploring another local wisdom that can be a context in learning mathematics.

AbstractThis article is intended to measure the effectiveness of using Article 33 of the 1945 Constitution for junior high school students and the improvement of teaching materials, in accordance with the principles of development. As an experimental research, the form of this research is a quasy experiment. The object of this research was 53 students in SMP Kota Singkawang. Data were collected using measurement techniques. This study uses a different test using t-test as a data analysis tool. Based on the SPSS output, the t-test results show that the significance = 0.00 <α 0.05, which indicates that there is a significant difference in learning outcomes between the pre-test and post-test results. Thus it can be concluded that the effective use of teaching materials has an impact on students' understanding of the material of Article 33 of the 1945 Constitution at SMP Kota Singkawang. Keywords: Economic Learning, Teaching Materials, Article 33 of the 1945 Constitution.
