Kegiatan pelatihan penggunaan metode jarimatika dan perkalian cepat dilaksanakan di SMP Negeri 4 Watampone yang dilaksanakan selama satu jam pelajaran. Dari hasil kegiatan pelatihan yang telah dilaksanakan disimpulkan bahwa pada kegiatan pelatihan siswa sangat antusias dan memberikan respon yang positif dalam mengikuti kegiatan tersebut. Siswa merasa sangat terbantu dengan penggunaan metode jarimatika dalam perhitungan cepat yang tadinya hanya mengandalkan hafalan. Pada proses pelaksanaan pengabdian terlihat siswa sangat aktif dalam mempraktekkan metode jarimatika dan dengan cepat mampu memahami metode perhitungan yang diberikan. Dengan pelatihan ini dapat merubah pandangan siswa mengenai matematika dengan perhitungan yang sulit menjadi matematika itu mudah dan menyenangkan.
The purpose of this study was to determine the activities, responses, and student learning outcomes with multi level instruction learning. Multi level instruction assignment learning strategy is a selling system adoption from multi level marketing strategy with special characteristics that there are students in first level and second level downlines and a teacher as an upline. Type of research is quasi-experimental by comparing two experimental groups. Experimental group one was given the STAD model with multi level instruction, and the other group was given regular STAD model. The research instruments used were student activity observation sheets, student response questionnaires, and learning outcomes test. The data obtained were analyzed descriptively and inferentially. The result indicates that both of them are effective to be applied in mathematic learning, but inferentially the outcomes of the experiment group one was higher than the experiment group two.
<p>This study describes students' ability to solve HOTS problems according to their self-confidence level in a grade 8 class at a junior high school in Pallangga. The type of research used is descriptive qualitative research. The research procedure includes the preparation, implementation, and analysis stages of research results. The subjects in the study were 3 grade 8 students at SMP Negeri 5 in the district of Pallangga. The subjects were selected by giving a questionnaire to all grade 8 students to select students who had high self-confidence, moderate self-confidence, and low self-confidence. The research refers to the four stages of the ability to solve mathematical problems based on Polya's steps, namely: understanding the problem, planning problem-solving strategies, carrying out calculations, and evaluating the results of problem-solving. The research instrument was a self-confidence questionnaire, an ability test to solve HOTS math problems based on Polya's steps, and interview guidelines. The results showed that there were differences in the ability to solve mathematical HOTS questions based on Polya's steps by the three selected subjects. The results showed that subjects with high self-confidence and moderate self-confidence were able to meet the indicators of understanding the problem, while subjects with low self-confidence were unable to meet the indicators of understanding the problem. At the stage of planning a problem-solving strategy, subjects with high self-confidence and moderate self-confidence were able to meet the indicators, while subjects with low self-confidence were unable to meet the indicators. At the stage of carrying out calculations, subjects with high self-confidence were able to meet the indicators, while subjects with moderate self-confidence and low self-confidence were unable to meet the indicators. And at the stage of re-examining the results of problem-solving, subjects with high self-confidence were able to meet the indicators, while subjects with moderate self-confidence and low self-confidence were unable to meet the indicator.</p><p><strong>BAHASA INDONESIA ABSTRACT: </strong>Penelitian ini bertujuan untuk mendeskripsikan kemampuan menyelesaikan masalah matematika soal HOTS ditinjau dari kepercayaan diri pada siswa kelas VIII SMP Negeri 5 Pallangga. Jenis penelitian adalah penelitian deskriptif kualitatif. Prosedur penelitian meliputi persiapan, pelaksanaan dan tahap analisis hasil penelitian. Subjek dalam penelitian adalah 3 orang siswa kelas VIII SMP Negeri 5 Pallangga. Subjek dipilih dengan memberikan angket kepada seluruh siswa kelas VIII untuk memilih siswa yang memiliki kepercayaan diri tinggi, kepercayaan diri sedang, dan kepercayaan diri rendah. Penelitian mengacu pada empat tahap kemampuan menyelesaikan masalah matematika berdasarkan langkah Polya yaitu: memahami masalah, merencanakan strategi pemecahan masalah, melaksanakan perhitungan, dan memeriksa kembali hasil penyelesaian masalah. Instrumen penelitian adalah angket kepercayaan diri, tes kemampuan menyelesaikan masalah matematika soal HOTS berdasarkan langkah Polya, dan pedoman wawancara. Hasil penelitian menunjukkan bahwa terdapat perbedaan kemampuan menyelesaikan masalah matematika soal HOTS berdasarkan langkah Polya oleh ketiga subjek yang dipilih. Berdasarkan hasil penelitian diperoleh bahwa subjek dengan kepercayaan diri tinggi dan kepercayaan diri sedang mampu memenuhi indikator memahami masalah, sementara subjek dengan kepercayaan diri rendah tidak mampu memenuhi indikator memahami masalah. Pada tahap merencanakan strategi pemecahan masalah, subjek dengan kepercayaan diri tinggi dan kepercayaan diri sedang mampu memenuhi indikator, sementara subjek dengan kepercayaan diri rendah tidak mampu memenuhi indikator. Pada tahap melaksanakan perhitugan, subjek dengan kepercayaan diri tinggi mampu memenuhi indikator, sementara subjek dengan kepercayaan diri sedang dan kepercayaan diri rendah tidak mampu memenuhi indikator. Dan pada tahap memeriksa kembali hasil penyelesaian masalah, subjek dengan kepercayaan diri tinggi mampu memenuhi indikator, sementara subjek dengan kepercayaan diri sedang dan kepercayaan diri rendah tidak mampu memenuhi indikator.</p>
This study aims to determine the effect of treatment on student learning outcomes in the algebraic structure course at the Department of Mathematics Education of the University of Muhammadiyah Makassar in virtual learning through the online learning system (SPADA). This study is a quasi-experimental design with a post-test-only control group whose results were analyzed using descriptive analysis and inferential analysis (mann whitney test). The population is the class of 2019 who is programming an algebraic structure course consisting of 3 classes, then a sample consisting of 2 classes was selected, namely, one experimental class taught through SPADA, and one control class taught in addition to using SPADA, namely, zoom meeting, google meet, email, and whatsApp groups. The instrument used is a test of student learning outcomes. The results obtained are that the average learning outcomes of students who are taught through SPADA are higher than the average learning outcomes of students who are taught other than through SPADA, but the results of the Mann Whitney test show that there is no significant difference from the learning outcomes of students who have been taught through SPADA or other than SPADA. Researchers suggest that providing virtual learning not only relies on one learning media but also on the synergy between one media and another, which will further optimize virtual learning.
