Abstract

AbstrakSeiring perkembangan zaman dan teknologi, media pembelajaran mengalami perkembangan yang pesat terutama media pembelajaran berbasis teknologi, yaitu smartphone. Namun sangat disayangkan bahwa penggunaan smartphone di Indonesia, didominasi oleh kegiatan komunikasi dan hiburan daripada kegiatan belajar. Masalah yang ditemukan ini, memotivasi sebuah penelitian pengembangan tentang aplikasi Mobile Learning yang dibuat dengan Android Studio sebagai sumber belajar dan sarana mengerjakan soal trigonometri SMA. Tujuan penelitian yaitu mengembangkan Mobile Learning yang valid, praktis dan efektif. Penelitian ini merupakan penelitian pengembangan menggunakan model ADDIE. Subjek penelitian yakni peserta didik kelas XI MIPA 2 dan 3 Semester 2 Tahun Ajar 2020/2021 SMA Kristen Satya Wacana sejumlah 10 peserta didik. Hasil validasi membuktikan bahwa Mobile Learning yang dikembangkan valid serta praktis. Hasil uji coba membuktikan bahwa aplikasi Mobile Learning dikategorikan layak dipakai dalam pembelajaran. Hasil pretest serta posttest juga menunjukkan bahwa Mobile Learning efektif meningkatkan hasil belajar, kemudian efektif menjadi sarana belajar serta mengerjakan soal matematika.  The Development of Android-based PINTHIR Mobile Learning as a Learning Source and Media for Solving Trigonometry Problem in High School  AbstractAlong with the times and technology, learning media has experienced rapid development, especially technology-based learning media, namely smartphones. However, it is unfortunate that the use of smartphones in Indonesia is dominated by communication and entertainment activities rather than learning activities. This problem found motivates development research on the Mobile Learning application made with Android Studio as a learning resource and a means of working on high school trigonometry problems. The research objective is to develop valid, practical, and effective Mobile Learning. This research is development research using the ADDIE model. The research subjects were 10 students of class XI MIPA 2 and 3 Semester 2 of the 2020/2021 Satya Wacana Christian High School. The validation results prove that the developed Mobile Learning is valid and practical. The trial results prove that the Mobile Learning application is categorized as suitable for use in learning. The results of the pretest and posttest also show that Mobile Learning is effective in improving learning outcomes, as well as being an effective means of learning and working on trigonometry questions.

Abstract

AbstrakKemandirian belajar, persepsi siswa, dan kemampuan pemecahan masalah merupakan faktor penting dalam belajar matematika. Penelitian bertujuan mengetahui pengaruh kemandirian belajar dan persepsi siswa mengenai guru secara bersama-sama terhadap kemampuan pemecahan masalah matematis siswa. Penelitian deskriptif kuantitaif korelasional ini dilakukan pada 120 siswa kelas X salah satu SMK di Koto Baru yang dipilih dengan teknik purposive sampling. Instrumen berupa angket kemandirian belajar dan persepsi siswa mengenai guru, serta tes soal essay. Analisis data menggunakan statistik deskriptif dan analisis statistik inferensial. Hasil penelitian menunjukkan terdapat pengaruh yang positif dan signifikan antara kemandirian belajar terhadap kemampuan pemecahan masalah matematis siswa, pengaruh yang positif dan signifikan persepsi siswa mengenai guru terhadap kemampuan pemecahan masalah matematis siswa, dan pengaruh positif dan signifikan terhadap kemandirian belajar dan persepsi siswa mengenai guru terhadap kemampuan pemecahan masalah matematis siswa. Faktor kemandirian belajar dan persepsi siswa perlu diperhatikan dengan baik untuk mengembangkan kemampuan pemecahan masalah.  Learning Independence and Students' Perceptions of Teachers on the Mathematical Problem Solving Ability of Vocational School StudentsAbstractIndependent learning, student perception, and problem-solving ability are important factors in learning mathematics. This study aims to determine the effect of learning independence and students' perceptions of teachers together on students' mathematical problem-solving ability. This correlational quantitative descriptive study was conducted on 120 students of class X one of the Vocational High Schools in Koto Baru. Selected by purposive sampling technique. Instruments in the form of a learning independence questionnaire and students' perceptions of teachers, as well as essay tests. Data analysis used descriptive statistics and inferential statistical analysis. The results showed that there was a positive and significant influence between learning independence on students' mathematical problem-solving ability, a positive and significant influence on students' perceptions of teachers on students' mathematical problem-solving ability, and a positive and significant effect on learning independence and students' perceptions of teachers on their abilities. students' mathematical problem-solving. Learning independence factors and student perceptions need to be considered properly to develop problem-solving ability.

Abstract

AbstrakGaya kognitif perlu diketahui untuk membantu pemilihan metode pengajaran yang sesuai kebutuhan siswa dalam belajar. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Conceptual Understanding Procedures (CUPs) berbantuan media handout terhadap kemampuan pemahaman konsep matematis ditinjau dari gaya kognitif. Penelitian eksperimen semu ini menggunakan posttest-only control design. Populasi pada penelitian ini mencakup seluruh siswa kelas VIII SMP di kota Metro. Penentuan sampel menggunakan teknik cluster random sampling. Sampel penelitian adalah 41 siswa (22 di kelas eksperimen dan 19 di kelas kontrol). Pengujian hipotesis menggunakan uji anava dua jalan. Berdasarkan hasil penelitian didapatkan kesimpulan bahwa model pembelajaran CUPs berbantuan media handout mempunyai pengaruh terhadap kemampuan pemahaman konsep matematis siswa, gaya kognitif field independent dan field dependent mempunyai pengaruh terhadap kemampuan pemahaman konsep matematis siswa dan tidak ada interaksi antara model pembelajaran dan tipe gaya kognitif terhadap kemampuan pemahaman matematis siswa.  CUPs Learning Model Assisted by Media Handout: Impact on Ability to Understand Mathematical Concepts in Terms of Cognitive StyleAbstractCognitive styles need to be known to help select teaching methods that are suitable for students' needs in learning. This study aims to determine the effect of the Conceptual Understanding Procedures (CUPs) learning model assisted by handout media on the ability to understand mathematical concepts in terms of cognitive style. This quasi-experimental research used a posttest-only control design. The population in this study includes all students of class VIII SMP in the city of Metro. Determination of the sample using cluster random sampling technique. The research sample was 41 students (22 in the experimental class and 19 in the control class). Hypothesis testing using two-way ANOVA test. Based on the results of the study, it was concluded that the CUPs learning model assisted by handout media had an influence on students' mathematical concept understanding abilities, field-independent and field-dependent cognitive styles had an influence on students' mathematical concept understanding abilities and there was no interaction between learning models and types of cognitive styles on understanding abilities. students' mathematical concepts.
