This study began with many students having low concept comprehension skills. This can be seen from the learning process that there are still many students who are less active, and there are still many students who still get grades below the KKM. the purpose of this study was to determine the ability to understand students 'mathematical concepts using the Think Talk Write learning model better than students' ability to understand mathematical concepts using conventional learning models in class VIII MTs Al-Ihsan. The type of this research is experimental, the design is Quasi Experimental, with Randomized Subjects Posstest Only Control Group Design. The sampling technique in this study is cluster random sampling, where class VIII.3 was chosen as the experimental class and class VIII.5 as the control class. Data collection techniques through concept understanding tests, then data analysis techniques used are inferential statistical analysis using the "t" test (Independent Sample t Test). Based on the results of research testing the hypothesis of this study obtained t count = 2.061 t table = -1.999. This means that the ability to understand mathematical concepts of students using Think Talk Write learning models is better than the ability to understand mathematical concepts of students using conventional learning models in class VIII MTs Al-Ihsan

The purpose of this study was to determine the ability to understand the concept with learning Bamboo Dance better than the ability to understand the concept with conventional learning VII grade students of SMP N 03 Sungai Lala. The type of this research is experimental research, with class VII B as an experimental class totaling 26 students and VII Â A as a control class with 25 students, the research design used was Randomized Subjects posttes only control group design. The results of the calculation of the hypothesis test obtained thitung = 3.159 and t table = 2.009. Because thitung is in the rejection area of H0, meaning that the average understanding ability of students' mathematical concepts with the application of the Bamboo Dance model is better than the average ability to understand mathematical concepts of students with conventional learning on line and angle material in class VII of Sungai Lala SMP Negeri 3.Keywords: Understanding the concept, Bamboo Dancing

Penelitian ini dilatarbelakangi dari permasalahan siswa dalam belajar matematika, seperti siswa beranggapan bahwa matematika merupakan mata pelajaran yang sulit dan kurang diminati. Anggapan tersebut muncul karena siswa kurang aktif, tidak serius dalam mengerjakan soal dan rasa ingin tahu yang kurang serta banyak memilih bermain dalam belajar matematika. Disaat pembelajaran berlangsung ditemukan siswa yang tertawa karena sibuk dengan aktivitasnya sendiri. Tujuan dari penelitian ini adalah untuk mengetahui ada peningkatan pemahaman konsep matematika melalui penggunaan Alat Peraga Dakon. Jenis Penelitian ini adalah Penelitian Tindakan Kelas (PTK) dengan teknik pengumpulan data dalam penelitian ini adalah tes pemahaman konsep matematika dan observasi.Â Dari hasil tes yang diperoleh menunjukan bahwa persentase ketuntasan 83,87% dengan target ketuntasan 75%. Hal ini dapat disimpulkan bahwa penggunaan alat peraga dakon matematika dapat meningkatkan pemahaman konsep matematika siswa.Kata kunci: penggunaan dakon matematika, pemahaman konsep matematika

Using the background of the problem is this research is the lack of knowledge of theachers and students about how use the application Google Classroom (GC) in learning activities, but there are still students do not have google account to log in the application GC. This research is a descriptive qualiative research. This study aims to determine how the quality of mathematics learning in the use of the application GC of combinatorics material for class XII IPA students of SMA Negeri 1 Pasir Penyu. The subjects of this study were selected based on the studentâ€™s daily test scores on combinatoric material using the application GC, where the subjects of this study included six students of class XII IPA 3 consisting of two students who had high test scores, two students who had mean test scores and two students who had low test scores. Data collection techniques are interview guidelines and questinnaire sheets. Furthermore, the data obtained will be analyzed based on indicators of the quality of mathematics learning. Data analyzed techniques in this study were data reduction, data presentation, and data verification. Based on the final results of the questionnaire sheets scores and the average posttest so that the average of both is 71,5 whit good categories, it can be concluded that the quality of mathematics learning in the use of the application GC of combinatorics material for class XII IPA 3 students of SMA Negeri 1 Pasir Penyu is good.

Abstrak: Penyebaran Covid-19 menjadi ancaman di setiap sektor kehidupan baik sektor ekonomi, sosial maupun pendidikan. Pada sektor pendidikan mengakibatkan pembelajaran yang biasanya dilakukan secara tatap muka beralih menjadi tatap maya atau daring/pembelajaran jarak jauh. Beberapa sekolah sudah siap untuk menerapkan pembelajaran jarak jauh/daring namun banyak juga sekolah belum siap untuk menerapkan pembelajaran jarak jauh/daring disebabkan karena belum terbiasa dan belum mengenal penggunaan platform pembelajaran. Maka perlu adanya sosialisasi dan workshop terkait penggunaan platform pembelajaran jarak jauh salah satunya dengan penggunaan google classroom. Google classroom dipilih karena penggunaannya cukup efisien, praktis dan dapat digunakan dengan cepat dan mudah. Metode kegiatan pengabdian kepada masyarakat ini dilakukan secara daring dengan cara penyampain materi kemudian dilanjutkan dengan workshop. Peserta kegiatan berjumlah 89 orang yang diikuti oleh guru dari berbagai daerah di Indonesia. Berdasarkan hasil angket mengenai keterlaksanaan kegiatan pengabdian kepada masyarakat diperoleh hasil respon peserta sebesar 80,30% untuk indikator manfaat kegiatan, 80,11% untuk konten/isi, 78,41% untuk umpan balik dan 77,27% untuk indikator penyampaian materi. Hal ini menunjukkan pembelajaran melalui platform google classroom dapat membantu peserta untuk menerapkan sistem pembelajaran jarak jauh, serta menjawab kesulitan yang dialami peserta dalam penggunaan google classroom. Â Abstract:Â The spread of Covid-19 is a threat in every sector of life, be it the economic, social and educational sectors. In the education sector, learning that is usually carried out face-to-face has switched to face-to-face or online / distance learning. Some schools are ready to implement distance / online learning, but many schools are not ready to implement distance / online learning because they are not familiar with and are not familiar with the use of learning platforms. So there is a need for socialization and workshops related to the use of distance learning platforms, one of which is the use of google classroom. Google classroom was chosen because it is quite efficient, practical and can be used quickly and easily. This method of community service activities is carried out online by delivering material then followed by workshops. The number of participants in the activity was 89 people followed by teachers from various regions in Indonesia. Based on the results of a questionnaire regarding the implementation of community service activities, the results of participant responses were 80.30% for indicators of activity benefits, 80.11% for content, 78.41% for feedback and 77.27% for indicators of material delivery. This shows that learning through the google classroom platform can help participants to implement a distance learning system, as well as answer the difficulties experienced by participants in using google classroom.

Penelitian ini bertujuan untuk mengetahui perbedaan kemampuan pemecahan masalah matematika antara siswa pada kelas yang memperoleh pembelajaran Talking Stick dengan siswa pada kelas yang memperoleh pembelajaran konvensional. Populasi penelitian ini adalah siswa kelas VII SMP Negeri 3 Pasir Penyu. Dari enam kelas, di peroleh 168 siswa yang tebagi di enam kelas. Jenis penelitian adalah Quasi Experimental Design, dengan rancangan penelitian Randomized Subjects posttes only control group design. Teknik analisis data yang digunakan adalah Cluster Random Sampling. Teknik analisis data yang digunakan terhadap soal tes kemampuan pemecahan masalahsiswa yaitu uji-t. Berdasarkan hasil penelitian pengujian hipotesis ditunjukkan oleh = 2,118 > = 2,005 dengan taraf signifikan 0,05. Artinya H0 di tolak, dengan demikian kemampuan pemecahan masalah matematika siswa dengan penerapan model Talking Stick lebih baik daripada hasil test kemampuan pemecahan masalah matematika siswa denan menggunakan pembelajaran konvensional pada kelas VII SMP Negeri 3 Pasir Penyu.
