Abstract

Penelitian ini bertujuan untuk mendeskripsikan keefektifan model pembelajaran berbasis inkuiri ditinjau dari prestasi belajar dan kepercayaan diri dalam belajar matematika siswa SMP. Penelitian ini adalah penelitian kuasi eksperimen dengan desain one-group posttest-only. Populasi penelitian ini adalah seluruh siswa kelas VII SMP Negeri 8 Yogyakarta yang terdiri dari 10 kelas. Penelitian ini menggunakan satu kelas yang terdiri dari 32 orang siswa sebagai sampel yang dipilih secara acak. Teknik pengumpulan data menggunakan teknik tes dan non tes. Instrumen pengumpulan data yang digunakan yaitu tes prestasi belajar dan angket kepercayaan diri dalam belajar matematika. Uji asumsi normalitas data menggunakan uji Kolmogorov-Smirnov satu sampel pada taraf signifikan α = 5%. Teknik analisis data untuk menguji keefektifan model pembelajaran ditinjau dari prestasi belajar dan kepercayaan diri dalam belajar matematika masing-masing menggunakan uji-t satu sampel pada taraf signifikan α = 5%. Hasil penelitian ini menunjukkan bahwa model pembelajaran berbasis inkuiri efektif ditinjau dari prestasi belajar dan kepercayaan diri dalam belajar matematika siswa. The effectiveness of the inquiry-based learning model in term learning achievement and self-confidence in learning mathematics of junior high school studentsAbstractThis research aimed to describe the effectiveness of the inquiry-based learning model in terms of learning achievement and self-confidence in learning mathematics of junior high school students. This study was a quasi-experimental with one-group posttest-only design. The population of this study was all students of 7th-grade of SMP Negeri 8 (Yogyakarta State Junior High School Number 8) consisted of ten classrooms. The research used a class consisted of 32 students as the sample that was randomly selected. The data was collected by using test and non-test techniques. The instruments to collect the data were an achievement test and a questionnaire about self-confidence in learning mathematics. The assumption test of data normality used the one-sample Kolmogorov-Smirnov test at 5% significant level. Data analysis techniques for the effectiveness of the learning model in terms of learning achievement and self-confidence in learning mathematics used the one-sample t-test at 5% significant level. The results of this study indicate that the inquiry-based learning model was effective in terms of students' learning achievement and self-confidence in learning mathematics.

Abstract

Penelitian ini bertujuan untuk menghasilkan produk berupa media pembelajaran berbasis STEM dengan augmented reality yang valid, praktis, dan efektif dalam meningkatkan kemampuan spasial matematis siswa. Jenis penelitian ini adalah penelitian pengembangan dengan model ADDIE yang diadaptasi dari Lee & Owens yang meliputi yaitu analyze, design, development, implementation, and evaluation. Implementasi media yang dikembangkan dilakukan di SMK Negeri 1 Pandeglang dengan melibatkan 25 orang siswa kelas XII RPL 2 dan 2 orang guru matematika. Hasil dari penelitian ini adalah sebuah media pembelajaran yang diberi nama "Artic" yang valid, praktis, dan efektif. Media pembelajaran dinyatakan valid berdasarkan penilaian dari tiga orang ahli media dan tiga orang ahli pendidikan, dengan persentase kevalidan secara berturut-turut sebesar 91% (sangat layak) dan 93% (sangat layak). Media dinyatakan praktis berdasarkan penilaian oleh guru dengan persentase penilaian sebesar 85% (sangat praktis) dan penilaian dari siswa dengan persentase penilaian sebesar 94% (sangat baik). Keefektifan media berdasarkan skor n-gain sebesar 0,42 dengan interpretasi terdapat peningkatan pada kategori sedang. Berdasarkan hasil tersebut, maka media pembelajaran yang dikembangkan layak digunakan untuk meningkatkan kemampuan spasial matematis siswa. AbstractThis study aimed to produce a product in the form of a learning media based on STEM with Augmented Reality which was valid, practical, and effective to improve students' mathematical spatial abilities. This study was a research and development with the ADDIE model adapted from Lee & Owens which includes analyzing, design, development, implementation, and evaluation. The implementation of the developed media was carried out at SMK (vocational high school) Negeri 1 Pandeglang, Indonesia by involving 25 students of class XII RPL 2 and two mathematics teachers. The results of this study were a learning media that was given the name "Artic" which was valid, practical, and effective. Learning media was declared valid based on the assessment of three media experts and three educational experts, with a percentage of validity respectively 91% (very feasible) and 93% (very feasible). The media was declared practical based on the assessment by the teacher with a percentage score of 85% (very practical) and an assessment by students with a percentage score of 94% (very good). The effectiveness of the media based on the n-gain score of 0.42 with the interpretation there was an increase in the medium category. Based on these results, the learning media developed was appropriate to be used to improve students' mathematical spatial abilities.
