Abstract

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.BAHASA INDONESIA ABSTRACT: 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 (Analyze, Design, Develop, Implement, Evaluate). 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.

Abstract

This study aims to determine the ability to understand the concept of fractions in grade VII students of SMP Kristen Kusu-Kusu Sereh Ambon. The type of research used is qualitative descriptive research. This research was carried out at SMP Kristen Kusu-Kusu Sereh Ambon, with the data source being class VII-1 students totaling 20 students, and the research subjects selected to be interviewed were three students. Researchers describe students' ability to understand fractional concepts by looking at the results of student answers and interviews. The results of this student's test refer to the question instructions and the student's accuracy in answering. The accuracy of the student's answers is adjusted to the assessment criteria for the test questions and the scoring criteria for the ability to understand fractional concepts with four indicators, namely indicators of the ability to provide examples and non-examples, indicators of the ability to present concepts in various forms of mathematical representation, indicators of the ability to use, utilize and select specific procedures or operations and indicators of the ability to apply concepts or algorithms in problem-solving. Based on the results of the fractional concept comprehension ability test and student interviews, one student met three indicators of concept understanding ability, namely indicators of the ability to provide examples and non-examples, the ability to present concepts in various forms of mathematical representation, and the ability to apply concepts or algorithms in problem-solving, and two students who met one indicator of concept understanding ability, namely indicators of ability to provide an example and non-example.
