The objectives of public devotion based on nationally excelled research this covers: (1) to develop a mathematical problem composing guide based on HOTS and SCE for qualified Madrasah Tsanawiyah teachers, (2) to provide training a mathematical problem composing based on HOTS and SCE for qualified Madrasah Tsanawiyah teachers using the developed guide. This study uses a 4-D (Four D) development research design model according to Thiagarajan, et al (1974: 5). This research model includes 4 main stages, namely the defining stage, followed by the design stage, then towards the development stage, and finally the distribution phase. The research instruments included: (a) the scale of the assessment of the quality of mathematical composing guide based on HOTS and SCE for Madrasah Tsanawiyah teachers, (b) scale of appraisal user response for guidebook, and (c) the Pre Test and Post Test Problem Sheets. The results of the study concluded that the guidebook for mathematical problem composing for SMP / MTs based on HOTS and SCE met the specified quality criteria, which were at least in the good category. In this study, the developed guidebook obtained an evaluation in the excellent category. However, testing to determine the level of practicality has not been done.

This research is a literature research that studies, analyzes and concludes literature and previous research on brain-based learning which expended by considering how the brain works. Then discuss and review of student's mathematical literacy which is the ability to formulate, implement and interpret mathematics in a variety of contexts, including the mathematical reasoning ability and using the concepts, procedures, and facts to describes, explain or predict the phenomena/events. Furthermore discuss how the impact of brain-based learning to improve students' mathematical literacy.

Etnomatematika dapat menciptakan pembelajaran yang lebih bermakna dan menarik bagi perserta didik.  Selain itu, dapat menumbuhkan rasa cinta terhadap budaya lokal. Penelitian ini bertujuan untuk mengeksplorasi etnomatematika dan mengkaji lebih mendalam tentang konsep matematika pada permainan tradisional layangan, menggunakan metode penelitian kualitatif dengan pendekatan etnografi. Hasil analisis dan pembahasan, menunjukkan bahawa terdapat etnomatematika pada permainan tradisional layangan. Pada bagian kerangka layangan terdapat konsep dasar matematika seperti garis, panjang diagonal, titik sudut, dan sudut. Berdasarkan pengamatan bentuk layangan dapat diperoleh rumus keliling dan luas layang-layang melalui pendekatan dua segitiga kongruen dan dua segitiga sama kaki pada bangun layang-layang. Selain terdapat unsur matematika, permainan tradisional layangan memiliki peran dalam penanaman karakter bagi peserta didik. Sehingga dapat disimpulkan bahwa layangan dapat digunakan sebagai media dalam pembelajaran matematika.

<p>This study took place in the village of Patronage UIN Sunan Kalidjaga Yogyakarta that consist of 13 hamlets (Klidon, Banjarsari, Wonosalam, Dongkelsari, Puntuk, Tanjung Sari, Karang Lo, Purworejo, Tanjung, Banturejo, Nglengkong and Surirejo), Sukoharjo Village, District Ngaglik, DIY Sleman regency. Data are collect and analysed in order to obtain results in a level of comfort. The analysis was performed by using a formula based on the comfort level Temperature Humidity Index (THI). The results showed that Hamlet Klidon, Banjarsari, Wonosalam, and Dongkelsari shows Not Comfortable, whereas Hamlet Puntuk, Tanjung Sari, Karang Lo, Purworejo, Tanjung, Banturejo, Nglengkong, Surirejo and Mujen show Strongly Comfortable mainly on the clock 10:00 to 15:00.</p>

Penelitian ini dilatarbelakangi oleh masih rendahnya partisipasi keaktifan dan prestasi siswa kelas VII C SMP Negeri 4 Geyer Grobogan Jawa Tengah dalam pembelajaran matematika. Hal tersebut berdasarkan studi awal yang menemukan bahwa siswa yang aktif baru 23,57% dari keseluruhan siswa dan rata-rata prestasi matematika hanya 66,07. Dengan menerapkan penelitian tindakan kelas dan dengan menggunakan strategi Wide Open Wonder (WOW) berhasil meningkatkan keaktifan dan prestasi matematika siswa. Penelitian ini dilaksanakan pada tahun pelajaran 2014/2015 terhadap 28 siswa kelas VII C SMP Negeri 4 Geyer Grobogan Jawa Tengah yang terlaksana sebanyak 2 siklus. Adapun teknik pengumpulan data dilakukan dengan observasi dan tes. Keberhasilan penelitian ini yaitu dapat meningkatkan keaktifan siswa hingga mencapai 58,57% dan meningkatkan rata-rata nilai prestasi matematika mencapai 75,36 serta sebanyak 85,71% siswa telah berhasil melampaui kriteria ketuntasan minimal (KKM).
