Abstract

Set is one of the main materials contained in the mathematics subject for 7th-grade junior high school in odd semesters. In the set material, there's no formula used, but there are various kinds of notations, symbols, and also diagrams. Basically, some or even most students still face various difficulties in understanding and working on problems in set operations. This study aims to determine the types of errors and the percentage of errors in 7th-grade junior high school's responses to set material test questions using Newman's error analysis procedure. In this study, we used a qualitative descriptive method, while the data processing technique was done by analyzing student answers based on questions that were test instruments. The research subjects were taken from students in the VII-E class at SMP IT Fithrah Insani, which included as many as 22 students. Then the subjects were analyzed, and based on the results of the research, it turned out that there were still errors in solving set questions. The most frequent error made by students is an encoding error of 40.91%. In this error, the student did not write a complete final answer, or even the conclusion of the solution, so that he did not answer the question posed by the problem.

Abstract

Tujuan penelitian adalah untuk mengembangkan media pembelajaran Visual Basic Application (VBA) Microsoft PowerPoint pada materi himpunan. Adapun metode yang relevan dalam mencapai tujuan tersebut yaitu metode pengembangan ADDIE. Tahapan-tahapan ADDIE yaitu Analyze, Design, Development, Implementation,dan Evaluate. Teknik pengumpulan data pada penelitian ini dengan instrumen lembar validasi media dan ahli materi, serta wawancara pada validator ahli tersebut. Teknik analisis data yang digunakan menggunakan pendekatan kuantitatif dengan menghitung persentase setiap indikator capaian yang kemudian diinterpretasikan. Hasil penelitian menunjukan berdasarkan ahli media yakni indikator access 90%, cost 93%, technology 87%, interactivity 80% dan organization 90% sedangkan berdasarkan ahli materi rata-rata capaian indikator tujuan pembelajaran 83%, kesesuaian materi 88% , kesesuaian dengan karakteristik siswa 88%, kesesuaian teori 92%, kesesuaian lingkungan 85% dan kesesuaian dengan gaya belajar 78% . Simpulan dalam penelitian ini menunjukkan tingkat validitas media pembelajaran VBA PowerPoint pada materi himpunan berdasarkan ahli media dan materi sangat valid untuk digunakan dalam pembelajaran matematika. The aim of the research was to develop the Visual Basic Application (VBA) learning media for Microsoft PowerPoint learning media on set material. The relevant method for achieving this goal is the ADDIE development method. The stages of ADDIE are Analyze, Design, Development, Implementation, and Evaluate. Data collection techniques in this research used validation instruments sheets for media experts and material experts, as well as interviews with both experts. The data analysis technique used uses a quantitative approach by calculating the percentage of each achievement indicator, which is then interpreted. The results showed that based on media experts, namely access indicators at 90%, cost at 93%, technology at 87%, interactive at 80%, and organization at 90%. Based on material experts, the average achievement indicators for learning objectives were 83%, material suitability 88%, suitability with student characteristics 88%, theory suitability 92%, environmental suitability 85%, and learning style suitability 78%. The conclusions in this study indicate the level of validity of VBA PowerPoint learning media on set material based on media experts, and the material is very valid for use in learning mathematics.
