Mathematics learning has always been a problem in the world of education in Indonesia especially in the Province of Maluku, which is a thousand island area. The geographical position of Maluku, which is an area of the archipelago, is quite extensive, affecting the quality of students in mathematics. One approach that is recommended to overcome mathematical problems of rural island-based students is realistic mathematics education (RME). The purpose of this study was to analyze the effect of RME on mathematical reasoning and communication skills in a rural context. The research design used was quasi experiment. The sample size was 130 students from several junior high schools in Central Maluku Regency. The instrument developed was in the form of problem descriptions to measure students' mathematical reasoning and communication skills. The findings prove that RME has a significant influence on students' mathematical reasoning and communication skills. Thus, RME can be recommended in improving students' mathematical reasoning and communication skills in the island-based rural context.
The Covid-19 pandemic has changed the pattern of education. Especially with the Independent Learning Program, teachers are required to be creative and innovative, teachers must create a happy atmosphere in learning. One way is to develop learning media that makes students enthusiastic in learning online. Learning videos are audio-visual media as a teacher's tool in delivering material to make it easy for students to understand and the Canva application that can support learning materials to be more interesting. The purpose of this service is to improve the quality of teachers by developing learning media according to the independent learning program. This service is carried out offline at SD N 1 and 3 Waimital. The result of this training is that teachers are able to develop video-based learning media because it really helps clarify subject matter so that teachers can implement the Independent Learning Program
This research is intended to find out the differences of students’ achievement which taught by using Team Assisted Individualization model and Think Pair Share model. Population of this research are 8th grade students of SMP Negeri 19 Ambon which consists of 10 classes. Research samples are students of class VIII-5 which stated as experiment group I (using TAI model) and students of class VIII-3 which stated as experiment group II (using TPS model). Each experiment group using different learning instruments, especially on students’ worksheets. This research is a quantitative research using posttest only group design. Data of this research is analyzed using t-test which supported by SPSS software version 22.0. Result shows that students group which using Team Assisted Individualization model has better achievement compare to Students on Think Pare Share class
<p>Most students find it difficult to visualize in a three-dimensional coordinate system in a spatial analytic geometry course, so they need learning videos that can help them. The purpose of this study was to determine the results of an expert team's validation of a learning video about the three-dimensional coordinate system for a spatial analytic geometry course. In addition, this study also aimed to see the students' responses to the three-dimensional coordinate system learning video for the spatial analytic geometry course. This research used the ADDIE development research method (Analyze, Design, Develop, Implement, Evaluate). This research was conducted in the Mathematics Education Study Program at Pattimura University. The validation results of a team of 3 experts had an average score was 3.74. Based on the validation criteria, the expert team is in the very valid category. Furthermore, the total score obtained from the student response questionnaires is 1304 which is in the good category. The recommendation from this research is that further research needs to be done to see whether the use of this learning video can improve students' mathematical problem solving abilities in a three-dimensional coordinate system.</p><p><strong>BAHASA INDONESIA ABSTRACT: </strong>Sebagian besar mahasiswa kesulitan melakukan visualisasi dalam sistem koordinat dimensi tiga pada mata kuliah geometri analitik ruang sehingga membutuhkan video pembelajaran yang dapat membantu mahasiswa dalam melakukan visualisasi. Tujuan dari penelitian ini untuk mengetahui hasil validasi tim ahli terhadap video pembelajaran sistem koordinat dimensi tiga pada mata kuliah geometri analitik ruang. Selain itu, penelitian ini juga bertujuan untuk melihat respon mahasiswa terhadap video pembelajaran sistem koordinat dimensi tiga pada mata kuliah geometri analitik ruang. Penelitian ini menggunakan metode penelitian pengembangan dengan model pengembangan ADDIE (<em>Analyze, Design, Develop, Implement, Evaluate</em>). Penelitian ini dilaksanakan di Prodi Pendidikan Matematika Universitas Pattimura. Hasil validasi tim ahli yang berjumlah 3 orang diperoleh jumlah skor rata-rata mencapai 3,74. Berdasarkan kriteria kevalidan validasi tim ahli termasuk kategori sangat valid. Selanjutnya, diperoleh jumlah skor total hasil dari angket respon mahasiswa adalah 1304 berada pada kategori baik. Rekomendasi dari penelitian ini adalah perlu dilakukan penelitian lanjutan untuk melihat apakah penggunaan video pembelajaran ini dapat meningkatkan kemampuan pemecahan masalah matematis mahasiswa pada sistem koordinat dimensi tiga.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
