Abstract

Studi ini bertujuan untuk menilai dampak penggunaan metode Pembelajaran Berbasis Masalah (PBL) terhadap pencapaian akademis siswa dalam pelajaran matematika. Penelitian ini menerapkan metode pendekatan kuantitatif dengan rancangan eksperimen satu kelompok yang melibatkan pretest dan posttestPeserta dalam penelitian ini adalah siswa dari kelas VIII A SMP Katolik Padadita, terdiri dari 12 siswa laki-laki dan 13 siswa perempuan, yang mengikuti perlakuan menggunakan metode pembelajaran PBL. Instrumen pengukuran yang digunakan adalah tes tertulis yang terdiri dari lima pertanyaan esai. Analisis data menggunakan uji independent t-test menunjukkan hasil yang signifikan, menunjukkan adanya dukungan untuk hipotesis alternatif (H1) dan penolakan terhadap hipotesis nol (H0). Dengan demikian, dapat disimpulkan bahwa penerapan model pembelajaran PBL secara signifikan meningkatkan pencapaian belajar matematika siswa kelas VIII SMP Katolik Padadita, terutama pada topik materi lingkaran.

Abstract

Model pembelajaran hybrid atau hybrid learning model hadir sebagai pilihan model pembelajaran disaat peralihan antara offline (tatap muka) dan online (dalam jaringan) muncul. Model ini diharapkan dapat menjawab solusi bagi kampus yang akan melaksanakan perkuliahan secara offline maupun online dalam waktu bersamaan. Tujuan penelitian ini adalah untuk mengetahui bagaimana pelaksanaan perkuliahan dengan menggunakan model pembelajaran hybrid pada mahasiswa Unkriswina Sumba. Selain itu, melalui penelitian ini juga, diharapkan dapat ditemukan faktor eksternal dan faktor internal baik yang mendukung dan menghambat keberlangsungan model pembelajaran hybrid di dalam kelas saat perkuliahan berlangsung. Metode yang digunakan dalam penelitian ini adalah metode kualitatif dengan pendekatan deskriptif, dimana nanti peneliti peroleh data dari hasil wawancara dan dokumentasi di lapangan kemudian peneliti deskripsikan dengan detail. Metode ini dipilih karena dapat dengan jelas menjelaskan faktor pendukung dan penghambat dari pelaksanakan model hybrid di kelas, sehingga menurut peneliti sangat cocok bila disandingkan antara metode dan model yang digunakan dalam penelitian ini. Dalam penelitian kali ini peneliti mencoba membuat tahapan penelitian yaitu tahap pertama tahap perencanaan, tahap kedua tahap implementasi, tahap ketiga tahap penilaian. Tahapan-tahapan ini, membantu peneliti dalam melihat proses implementasi penggunaan pembelajaran hybrid selama perkulihan berlangsung di kampus Unkriswina Sumba.

Abstract

The low understanding of learning concepts among students in mathematics learning is caused by various factors, one of which is the lack of use of instructional media resulting in students being more passive. The purpose of this study is to explore the effects of implementing a learning model on students' understanding of mathematical concepts. The research method used is a quantitative approach with a one-group pre-test-post-test experimental design. The study population consists of all eighth-grade students at Anda Luri Catholic Junior High School, divided into four classes: VIII A (29 students), VIII B (30 students), VIII C (30 students), and VIII D (29 students). The subjects of this study are students from VIII C who underwent treatment using the instructional model. The research instrument used is a written test consisting of five essay questions. To evaluate the impact of the instructional model, an independent t-test was conducted. The analysis of the results shows a significant difference, thus supporting the alternative hypothesis while rejecting the null hypothesis. Therefore, it can be concluded that the use of the instructional model has a significant impact on the understanding of mathematical concepts among eighth-grade students, especially in the topic of systems of linear equations with two variables.
