Abstract

Pembelajaran matematika memerlukan bantuan media pembelajaran untuk memvisualisasikan materi yang bersifat abstrak. Penelitian ini bertujuan untuk mengembangkan media pembelajaran interaktif berbasis articulate storyline 3 pada materi unsur-unsur dan bagian-bagian lingkaran untuk siswa SMP yang valid, praktis, dan efektif untuk digunakan dalam pembelajaran. Pengembangan media pembelajaran interaktif berbasis articulate storyline 3 dilakukan dengan prosedur penelitian model ADDIE dengan lima langkah yakni analisis, perancangan, pengembangan, implementasi, dan evaluasi. Media pembelajaran interaktif berbasis articulate storyline 3 telah diujicoba oleh siswa kelas VIII-G SMPN 5 Mataram. Kevalidan media pembelajaran diperoleh pada tahap pengembangan melalui analisis hasil angket validasi dengan skor 0,87 dan kategori sangat valid. Kepraktisan media pembelajaran diperoleh pada tahap ujicoba melalui analisis angket kepraktisan dengan skor 87% dan kategori sangat praktis. Keefektifan media pembelajaran dilihat dari persentase ketuntasan klasikal siswa. Diperoleh persentase ketuntasan klasikal siswa sebesar 86%, sehingga media pembelajaran memenuhi kriteria keefektifan. Media pembelajaran interaktif berbasis articulate storyline 3 dinyatakan valid, praktis dan efektif untuk digunakan dalam pembelajaran.

Abstract

This study aims to describe the types of error experienced by students by referring to indicator of errors by Kastolan theory, scaffolding that can reduce student errors, and how scaffolding test affects student. This type of study is qualitative study. The subjects in this study were 4 students. The selection of subjects used simple random sampling technique. The instruments used were test instruments and interview guidelines. The data analysis technique uses the application model of Miles & Huberman’s theory: 1) Data collection, 2) Data condensation, 3) Data display, 4) Drawing and verifying conclusions. The results showed: 1) The errors experienced by students when working on test questions included three types of errors, namely conceptual error, procedural error, and technique error. The percentage of students who made conceptual errors was 35.7%, students who made procedural errors were 54.8%, and students who made technical errors were 38.1%; 2) From the application of scaffolding to 4 research subjects who committed 3 types of errors, it was obtained that conceptual errors were more suitable given scaffolding level 2, which is explaining: showing and telling. While procedural errors are more suitable given scaffolding level 2, which is explaining: telling. In the scaffolding technique errors that are suitable are level 1 scaffolding, which is reviewing: interpreting students actions; 3) After being given scaffolding, the errors made by students were significantly reduced from before being given scaffolding.

Abstract

This study aims to determine the effect of the Problem-Based Learning (PBL) model on student activity and learning achievement. The research was conducted at SMP Negeri 1 Aikmel during the 2022/2023 academic year. This is a quantitative study with a quasi-experimental approach using a posttest-only non-equivalent control group design. The population in this study consists of all eighth-grade students at SMP Negeri 1 Aikmel for the 2022/2023 academic year. The sample includes 30 students from class VIII A and 30 students from class VIII C, which serve as the experimental and control groups, respectively, selected based on the similar or homogeneous abilities of both classes. Data on student activity and learning achievement after the treatment were collected using questionnaires and tests. Quantitative data analysis was performed using multivariate Hotelling's T² test, followed by Bonferroni t-tests, and then an independent samples t-test. The three statistical tests yielded a significance value of 0.000 < 0.05, leading to the rejection of the null hypothesis (H0), indicating a significant difference in the mean scores between the two groups in terms of student activity and learning achievement, both simultaneously and separately. The results of the study show that the Problem-Based Learning (PBL) model has an impact on student activity and learning achievement in the topic of linear equations for eighth-grade students at SMP Negeri 1 Aikmel during the 2022/2023 academic year.
