The purpose of this study was to find out how the mathematical communication skills of students in solving the problem of flat building of class VII triangles in one of the SMP in the city of Cimahi. Data collection uses written tests for 33 students. The research method used is descriptive qualitative research that is analyzing students' difficulties in solving mathematical communication skills on indicators stating everyday events and lowering the quadrangular flat building area formula of grade VII students of junior high school. The results of this study can be concluded that there are 6.06% (2 students) who have excellent mathematical communication skills, 93.94% (33 students) have good mathematical communication skills and 0% (no students) who have communication skills mathematically is not good at problem 1 which indicator states everyday events and decreases the formula of quadrilateral flat building. This is due to the lack of ability of students to communicate their ideas so that they cannot solve problems in the given questions and even if asked they can only smile and be quiet.

Penelitian ini bertujuan menghasilkan perangkat pembelajaran matematika dengan pendekatan penemuan terbimbing untuk meningkatkan kemampuan berpikir kritis dan komunikasi matematis serta mendeskripsikan kualitas hasil pengembangan perangkat tersebut. Kualitas hasil pengembangan ditentukan berdasarkan pada kriteria dari Nieveen, yaitu valid, praktis, dan efektif. Penelitian ini merupakan penelitian pengembangan. Model pengembangan yang digunakan diadaptasi dari model Dick dan Carey. Adaptasi model Dick dan Carey menghasilkan 3 tahap pengembanan (define, design, dan develop). Subjek uji coba dalam penelitian ini adalah 60 siswa kelas 8 SMP Muhammadiyah 3 Yogyakarta. Instrumen yang digunakan antara lain lembar validasi, lembar penilaian dari guru dan siswa, lembar observasi keterlaksanaan pembelajaran, serta tes kemampuan berpikir kritis dan komunikasi matematis. Analisis data kevalidan dan analisis data kepraktisan masing-masing dilakukan dengan cara mengkonversi data kuantitatif berupa skor hasil penilaian menjadi data kualitatif berupa nilai standar skala lima. Analisis data keefektifan tes ketercapaian kompetensi dilakukan dengan cara menentukan persentase ketuntasan minimal, sedangkan analisis tes kemampuan berpikir kritis dan komunikasi matematis ditentukan peningkatannya.  Hasil validasi ahli, penilaian dari guru dan siswa, observasi keterlaksanaan pembelajaran, dan hasil tes kemampuan berpikir kritis dan komunikasi matematis siswa memberikan bukti bahwa perangkat pembelajaran telah memenuhi kriteria valid, praktis, dan efektif. Developing instructional kits using the guided discovery to increase creative thinking and mathematical communication skills AbstractThis research is aimed to produced learning kits using guided discovery approach to increase the creative thinking and mathematical communication skills and to describe the quality of the result of the development. The quality of learning kits determined based on Nieveen’s criteria, those are valid, practical, and effective. This research is development research adapted from Dick, and Carey model. The modified of this model resulted 3 stages of development steps (define, design, and develop). The subjects of this study are 60 grade 8 students of Muhammadiyah Junior High School 3 of Yogyakarta. The research instruments were validation sheet, assessment sheets from teacher and students, learning observation sheet, and critical thinking and mathematical communication skills test. The validity and practicality data analysis were done by converting the actual score into qualitative data with standard scale of five. The effectiveness of data analysis was done by determining the percentage of minimum completeness, while the analysis of critical thinking skills and mathematical communication tests determined the improvement. The results of experts’ validation, assessments from teachers and students, learning observation, and critical thinking and mathematical communication skills test, provide the evidence that the learning kits are valid, practical and effective.

AbstrakPewarisan budaya menjadi langkah kecil untuk dapat terus melestarikan budaya di suatu daerah. Namun, perkembangan teknologi terkadang mampu menggeser upaya pewarisan budaya tersebut. Penelitian ini bertujuan untuk mendeskripsikan proses pewarisan budaya keterampilan dalam pembuatan kerajinan marmer melalui kegiatan “manjing”. Penelitian ini menggunakan metode penelitian kualitatif melalui studi fenomenologi. Pengumpulan data dilakukan melalui teknik observasi, wawancara, dan dokumentasi. Analisis data dilakukan dengan menggunakan tiga tahap yakni (1) reduksi data, (2) display data, dan (3) penarikan kesimpulan. Penentuan keabsahan data dengan menggunakan teknik perpanjangan waktu penelitian dan triangulasi. Hasil penelitian menunjukkan bahwa kegiatan manjing dilakukan secara rutin. Proses pewarisan dilakukan oleh pengrajin marmer junior mulai dari upaya mengamati, menirukan, dan mempraktekkan hal-hal apa saja yang dilakukan oleh pengrajin marmer senior. Proses pewarisan budaya difokuskan pada kreativitas pembuatan kerajinan marmer. Upaya ini terdapat unsur pembelajaran di dalamnya, dalam konsep pendidikan kemudian proses ini termasuk dalam ranah pendidikan informal.AbstractCultural inheritance is a small step to be able to continue to preserve culture in an area. However, technological developments are sometimes able to shift the effort of cultural inheritance. This study aims to describe the process of cultural inheritance of skills in making marble crafts through "manjing" activities. This research uses qualitative research methods through phenomenology studies. Data collection is done through observation, interview, and documentation techniques. Data analysis was performed using three stages namely (1) data reduction, (2) data display, and (3) conclusion drawing. Determination of the validity of the data by using research time extension and triangulation techniques. The results showed that the Manjing activities were carried out routinely. The process of inheritance is carried out by junior marble craftsmen from the effort of observing, imitating, and practicing what things are done by senior marble craftsmen. The process of cultural inheritance is focused on the creativity of making marble handicrafts. This effort has an element of learning in it, in the concept of education then this process is included in the realm of informal education.

Mathematical communication skills are one of the competencies that students must have in the 21st century.  This study aims to anylize and describe students’ mathematical communication skills in terms of self efficacy on the polyhedrons material. The research used descriptive qualitative methods. The subjects were 9 grade students of An nashichah private junior high school selected purposively.  Data was collected through online test, questionnaires and interviews using WhatsApp. The data analyzed through 3 stages, namely data reduction, data presentation and conclusions. The results showed that the students’ mathematical communication skills were low. When viewed from students’ self efficacy, high self efficacy students have high mathematical communication. Meanwhile, low and moderate self efficacy students have low mathematical communication skills. The use of Whatsapp media is not able to support students mathematical communication skill and self efficacy. The tachers need to design learning media to help students improve their mathematical communication skills and self efiicacy.
