Mathematic has several goals that must be achieved, one of which is to make the students have the ability to understand concepts, to explain the interrelationships between concepts and apply these concepts appropriately in problem solving. For this reason, teachers are required to be a medium in transferring knowledge to students so that students are motivated in learning mathematics at school. This training of newsprint-waste processing was aimed at Mathematics teachers at SMP Negeri 3 Bireuen to stimulate the ceativity of the teachers in providing satisfying math teaching aids. The implementation of this community service activity was carried out in two stages, namely the preparation stage and the implementation stage, where the implementation stage consisted of two activities, namely the presentation of training material and direct practical assignments in the form of making mathematical teaching aids made from newsprint. The training on processing newsprint-waste into math teaching aids for teachers showed a positive impact on students' interest and learning outcomes at SMP Negeri 3 Bireuen. The outputs of this activity were: 1) various types of mathematical teaching aids made from newsprint that can be used in the teaching and learning process; 2) increase the creativity of teachers and students in their work; 3) produce math teaching aids that have the potential to generate high selling points for other schools.
The low level of literacy and numeracy skills for elementary school students is something that deserves attention so that it can change the level of children's abilities to be better at strengthening literacy and numeracy. The purpose of this activity is to increase the learning interest of elementary school students from various levels related to literacy and numeracy skills. This activity was carried out in Bandar Bireuen Village by utilizing existing village facilities and places. In addition, the service team from the lecturers and students also brought and provided some reading materials and mathematics learning media that could be used as a reference for children while studying. This activity took place in an orderly manner, the children looked enthusiastic with innovative and fun learning methods so as not to make children get bored quickly in learning. The children's vacation time is utilized by useful activities which are continuously accompanied and facilitated by a team of lecturers and students from the Mathematics Education Study program Almuslim University.
Tujuan penelitian ini adalah untuk mengetahui adanya peningkatan kemampuan berpikir kritis matematis siswa dengan penerapan model pembelajaran Problem Based Learning (PBL) dibandingkan model pembelajaran konvensional pada materi Teorema Pytagoras. Penelitian dengan pendekatan kuantitatif ini mengambil sampel 2 kelas di SMP Negeri 1 Peusangan, yaitu kelas VIII-7 sebagai kelas eksperimen dan kelas VIII-5 sebagai kelas kontrol dengan jumlah siswa masing-masing kelas 25 orang. Data dianalisis dengan menggunakan tes dan observasi. Hasil pengujian dengan hipotesis menggunakan uji t dengan taraf signifikan α = 0,05 diperoleh > ( 3,77 > 1,68 ), sehingga ditolak dan diterima. Dengan demikian, pembelajaran dengan model Problem Based Learning lebih baik dalam meningkatkan kemampuan berpikir kritis matematis siswa dari pada model pembelajaran konvensional pada materi Teorema Pytagoras.
Pengabdian ini dilakukan untuk dapat meningkatkan kemampuan guru dalam menyusun instrumen Penelitian Tindakan Kelas (PTK) dan mempu merancang pembelajaran PTK dengan sistematika hingga tahap refleksi dan evaluasi sehingga dpaat dilakukan perbaikan terhadap hasil yang kurang optimal pada tahap atau siklus selanjutnya. Pendekatan yang dilakuan pada kegiatan pengabdian ini adalah participant active learning dimana peserta ikut berpastisipasi dalam kegiatan pengabdian secara aktif. Jumlah peserta yag mengikuti adalah 20 orang yang terdiri dari beberapa perwakilan dari Sekolah Dasar di Kabupaten Bireuen. Berdasarkan hasil Pengabdian dan proses evaluasi pada kegiatan ini diperoleh bahwa terjadi peningkatan kemampuan para guru dalam merancang intrumen PTK dan melaksanakan PTK yang sebenarnya secara sistematis dan hasil respon yang diperoleh juga dengan capaian respon yang sangat baik.
