This study aims to describe the symbols and geometry that exist in the traditional house of the Lio tribe of Wolokoli Village, Wolowaru District, Ende Regency in ethnomathematics perspective in terms of mathematical concepts. This type of research is qualitative research with an ethnographic approach. The subjects of this study consisted of several informants (chiefs, village heads, teachers and students). Using observation and interview techniques, and using qualitative descriptive analysis. The results showed the existence of symbol shapes and geometry in the building of traditional houses of the Lio tribe of Wolokoli Village, Wolowaru District, Ende Regency. Other symbolic forms include leke (foundation pillars made of stone and wood), there are twenty oval-shaped stone pillars and one rectangular wooden pole, Tenga (lante beam) in the form of a tube. Dalo is rectangular in shape. Rectangular lure. Wisu (four main pillars) shaped beam. Kebi (wall) is rectangular in shape. Mangu (nok pole) shaped beam. Block shaped jara. Pene / Pere is rectangular in shape. Eba beams. Lara is a block. Hubu (roof) is made of trapezoid-shaped reeds. Form symbols and geometrical structures that exist in the traditional Lio Tribe of Wolokoli Village, namely lines, angles, squares, rectangles, triangles, trapezoid, parallelogram, triangles, hexagons, beams, tubes, and triangular prisms. The shape in these parts of the house can change the paradigm of children and society that mathematics has a relationship with daily activities and relationships with culture and can be learned in a fun way in solving problems of learning geometry material.

Penelitian ini bertujuan untuk mengetahui aktivitas, minat, dan hasil belajar mahasiswa program studi Pendidikan Matematika Universitas Flores menggunakan media Geogebra dalam pembelajaran geometri ruang. Jenis penelitian adalah penelitian tindakan kelas yang terdiri dari dua siklus. Tiap siklus terdiri dari empat tahap, yakni perencanaan, pelaksanaan, observasi, dan refleksi. Subyek penelitian ini adalah mahasiswa Program Studi Pendidikan Matematika sebanyak 24 orang. Teknik pengumpulan data menggunakan teknik observasi, tes dan angket. Data yang dikumpulkan dianalisis menggunakan analisis deskriptif. Hasil analisis menunjukkan adanya peningkatan minat belajar mahasiswa dari pra siklus ke siklus I 1,37%, dari siklus I ke siklus II 0,8%. Hasil observasi pra siklus, semua aspek pada aktivitas mahasiswa belum mencapai target yang diinginkan, sedangkan siklus I semua aspek pada aktivitas mahasiswa belum mencapai target yang diinginkan kecuali pada aktivitas mengerjakan tugas. Siklus II, semua aspek aktivitas mahasiswa sudah mencapai target yang diinginkan. Nilai rata-rata hasil belajar pra siklus diperoleh 63,9 dan persentase ketuntasan klasikal 70,83%, sedangkan pada siklus I memperoleh nilai rata-rata 65,8 dengan ketuntasan belajar klasikal 75%. Siklus II nilai rata-rata hasil belajar 70,2 dengan ketuntasan klasikal 87,5%. Berdasarkan hasil analisis di atas dapat disimpulkan bahwa ada peningkatan aktivitas, minat, dan hasil belajar mahasiswa dalam pembelajaran Geometri Ruang menggunakan Media Geogebra.

Penelitian ini bertujuan untuk mengetahui hubungan antara motivasi belajar terhadap tingkat stres mahasiswa yang sedang menulis tugas akhir (skripsi). Jenis penelitian yang digunakan adalah penelitian kuantitatif. Populasi dalam penelitian ini adalah Mahasiswa Semester akhir Program Studi Pendidikan Matematika yang sedang menulis skripsi. Sampel dalam penelitian ini berjumlah 26 orang. Teknik  pengambilan sampel menggunakan teknik Simple Random Sampling. Hasil penelitian menunjukkan bahwa motivasi mahasiswa dalam menulis tugas akhir tergolong cukup yaitu sebesar 66% dan untuk tingkat stress mahasiswa berada pada kategori sedang yaitu sebesar 77%, sedangkan hubungan motivasi terhadap tingkat stress mahasiswa diperoleh nilai Sig. (2-tailed) sebesar 0.000 dan diketahui nilai r hitung sebesar 0.877. Berdasarkan  hasil penelitian, dapat disimpulkan bahwa terdapat hubungan antara motivasi terhadap tingkat stress mahasiswa dalam penulisan tugas akhir (Skripsi).

This study aims to (1). To find out the process of learning mathematics during the Covid-19 pandemic. (2). To find out what the headmaster was doing in learning mathematical during the Covid-19 Pandemic. The research method used is using descriptive qualitative research method. Data collection techniques used interview techniques and documentation. The subject in this research is the principal, mathematics teacher and four students who are randomly selected. The results obtained from this study indicate (1). The process of learning mathematics during the Covid-19 pandemic described modules or material summaries and assigning assignments to student. (2). To see what the headmaster did in learning mathematical during the Covid-19 pandemic. Thus suggested that teachers should able to prepare the material properly so that students do not get bored with online learning. Students must take advantage of their free time to always explore the material that the teacher has distributed. For subsequent researchers who conduct research related similar, we use a broader subject.

In the world of education, teachers rarely associate daily life (traditional games) with mathematical material. Traditional games are one of the media that can be used in learning. This research aims to find out the mathematical concepts contained in the game. This research uses ethnographic research. The subjects in this study were 3 people who played marbles games. The instrument of this study is the documentation and diaries used by researchers at the time of observation. The research location is Ende Selatan Subdistrict, Boa'nawa Village. Data collection techniques use observation data directly to the players marbles. The results showed that there were mathematical aspects in the game of marbles, namely the introduction of the concept of addition, the concept of subtraction, the instroduction of the concept of distance, the concept of a flat wake. These concepts are used as learning media aids.
