Abstract

Penelitian ini bertujuan untuk mengetahui apakah ada perbedaan keefektivitasan antara Real Lab dan Virtual dengan melihat hasil belajar siswa yang mendapat pembelajaran model problem based learning (PBL) menggunakan Real Lab atau pembelajaran model PBL menggunakan Virtual Lab. Populasi dalam penelitian ini adalah seluruh siswa kelas XI SMA Negeri 3Medan yang mengambil jurusan IPA. Sampel yang digunakan dalam penelitian ini diambil secara purposive sampling sebanyak dua kelas, yakni satu kelas sebagai kelas eksperimen I yang dibelajarkan dengan penerapan model PBLmenggunakan Real Lab dan satu kelas sebagai kelas eksperimen II yang dibelajarkan dengan penerapan PBL menggunakan Virtual Lab. Instrumen yang digunakan pada penelitian ini terdiri dari instrumen tes yang disusun dalam bentuk tes objektif dengan jumlah soal sebanyak 20 soal yang telah dianalisis dan dinyatakan memenuhi syarat uji validitas isi melalui validator ahli, tingkat kesukaran, daya pembeda, distraktor validasi butir dan reliabilitas, perhitungan rata-rata, varians, dan standard deviasi. Berdasarkan hasil uji persyaratan data, diketahui bahwa data hasil pretest dan posttest pada kelas eksperimen I dan eksperimen II berdistribusi normal dan homogen. Untuk uji hipotesis mengenai hasil belajar dengan taraf 0,05 diperoleh data thitung > ttabel yakni2,25 > 2,00, yang berarti Ha diterima dan tolak Ho yaitu Ada perbedaan antara hasil belajar siswa pada materi pokok Titrasi Asam Basa dengan model PBL menggunakan media Real Lab dan model PBL menggunakan media Virtual Lab sehingga dapat dikatakan dari hasil temuan peneliti bahwasannya media real lab lebih efektif daripada media virtual lab

Abstract

This study aims to show: (1) the difference between the student learning outcomes taught by the PBL model using weblog media (PBL-WM)  and taught by the same learning model but not using the media (PBL); (2) the correlation between student learning motivation and PBL-WM improvement; (3) differences in student learning motivation  based on PBL-WM and PBL. The sample studied was class XI student of SMA Negeri 1 Percut Sei Tuan in the academic year 2019/2020 on the reaction rate teaching in 2013 curriculum. The instrument that used by test (learning outcome) and non-test (motivation). The results showed the average increase in PBL-WM was 74.7; while the average increase in PBL was 62,658. The average student motivation based on PBL-WM was 85.92; while the average student motivation based on PBL was 78.45. The statistical analysis results of SPSS 22.0 at α=5% can be stated that (1) PBL-WM was higher than PBL; (2) there was a significant correlation between student learning motivation and increase in PBL-WM , with a correlation coefficient of 0.925 and the contribution of learning motivation to increase PBL-WM of 85.5% while 14.5% was influenced by other factors; (3) student motivation based on PBL-WM  was higher than PBL.

Abstract

This study aimed to determine the needs of learning media in schools, the feasibility of the media created following the National Education Standards Agency (BSNP) criteria, and the effectiveness of the learning media on student learning outcomes. This research employed the ADDIE method (Analysis, Development, Design, Implementation, and Evaluation) involving 30 class X (tenth-grade) students. According to the analysis results of the Lectora Inspire media, the mean score of the content feasibility aspects was 3.88 (highly feasible), and the mean score of the presentation feasibility aspects was 3.89 (highly feasible). Furthermore, the developed media was implemented in the teaching and learning process to determine its effect on student learning outcomes. The test incorporated multiple-choice questions. In the implementation phase, the mean score of the pretest was 46.83, while the mean score of the posttest was 81.66. Afterward, the evaluation stage compared the posttest results and the school's passing grade (81.66 70), revealing that the developed learning media significantly affected student learning outcomes.
