Abstract

Calculus is a branch of mathematics that must be studied in school, especially at the high school level. One of the subjects in calculus is the application of integral on the volume of solid of revolution. The use of learning video as media can help students in a conceptual understanding of the volume of solid of revolution, which is one of the abstract objects in calculus. This article discusses the development of solid revolution learning videos' volume. It describes students' perception, pre-service mathematics teachers, and in-service mathematics teachers in the video. The subjects who participated in this study were 48 students in grade 12 in one state high school in Sambas Regency, West Borneo, 8 pre-service mathematics teachers of one of the universities in Yogyakarta, and 3 high school mathematics teachers in Sambas Regency. Data were collected by using a questionnaire consisting of several open questions. Through open questions, subjects were intended to express their ideas or opinions about the learning video. The finding showed that most respondents have positive perceptions of calculus learning video. 76,74% of students agree that the video is suitable for use at the beginning of learning this subject; all in-service mathematics teachers agree, and 75% of pre-service mathematics teachers also agree. This indicates that the learning video can be used as one of the teaching aids in the learning of solid revolution

Abstract

Penelitian ini merupakan penelitian pengembangan yang bertujuan untuk mengembangkan media pembelajaran video animasi yang valid, praktis dan efektif. Subjek penelitian ini adalah 34 orang siswa yang terdiri dari 12 orang siswa laki-laki dan 22 orang siswa perempuan dari salah satu SMP Negeri di Yogyakarta. Teknik pengumpulan data dilakukan dengan angket penilaian kepraktisan media oleh guru dan siswa, serta tes kemampuan spasial yang terdiri dari 12 butir soal pilihan ganda untuk menguji masing-masing komponen kemampuan spasial yaitu spatial visualization, spatial orientation, dan spatial relation. Hasil penelitian menunjukkan bahwa penilaian yang diperoleh dari ahli materi dan ahli media menyatakan media yang dikembangkan memenuhi kriteria valid, sedangkan hasil penilaian yang diberikan oleh guru dan siswa menyatakan media memenuhi kriteria praktis. Media tersebut juga dinyatakan efektif jika ditinjau dari kemampuan spasial karena sebanyak 75,9% siswa berhasil memperoleh skor ketuntasan. Kemampuan spasial sangat penting dimiliki oleh siswa karena banyak penelitian yang menyatakan bahwa kemampuan spasial berpengaruh terhadap kesuksesan seseorang di bidang Science, Technology, Engineering dan Mathematics (STEM), serta terhadap prestasi matematika siswa. This research is a development research which aims to develop a valid, practical and effective animated learning video. The subjects involved were 34 students consisting of 12 male and 22 female students from one of the state junior high schools in Yogyakarta. Data collection were carried out with a questionnaire assessment of the practicality of the media by teachers and students, as well as a spatial ability test consisting of 12 multiple choice questions to test each component of spatial ability, namely spatial visualization, spatial orientation, and spatial relations. The results showed that the assessment obtained from material experts and media experts stated that the developed media met valid criteria, while the assessment results given by teachers and students stated that the media met practical criteria. The media was also effective when viewed from spatial ability because 75.9% of students achieved mastery level scores. Spatial ability is very important for students as reported by many studies stating that spatial ability influences a person's success in the fields of Science, Technology, Engineering and Mathematics (STEM) and related to students’ mathematics achievement
