Abstract

This research was aimed to determine: the effect of model problem based learning (PBL), project based learning (PjBL) and conventional learning to: biology learning outcomes of students in the matter of environmental pollution in SMA Negeri 2 Kota Tebingtinggi. A quasi-experiment research used pretest-posttest control group design. Samples were selected using random cluster sampling technique and divided into experiment and control classes. The tenth class of sains-2 was applied with conventional learning (control), the tenth class of sains-3 was applied with problem based learning (PBL), and the tenth class of sains-4 was applied with project based learning (PjBL). Data were analyzed using Analysis Covarian (anacova) at the level of significance α = 0.05 and followed by Tukey’s test with SPSS ver 21.0. The results showed that: There was an effect of learning model to biology learning outcomes (P= 0,025). Biology learning outcomes that learned with problem based learning (81,46 ±  6,59) was higher than the project based learning (81,43 ± 10,14) and conventional learning (65,43 ± 7,10). Based on the results showed that problem based learning (PBL) is better than project based learning (PjBL) and conventional learning.

Abstract

Pemahaman konsep bilangan cacah di tingkat dasar sekolah masih menjadi tantangan, terutama karena kurangnya media pembelajaran yang kontekstual dan menarik. Penelitian ini bertujuan untuk mengembangkan media pembelajaran berbentuk supermarket yang relevan dengan kehidupan nyata siswa guna meningkatkan hasil belajar matematika. Metode yang digunakan adalah Research and Development (R&D) dengan model Borg & Gall yang dimodifikasi. Penelitian dilakukan secara deskriptif kualitatif, melibatkan ahli materi, ahli media, guru, dan siswa kelas IV SD. Teknik pengumpulan data meliputi observasi, wawancara, angket, dan tes hasil belajar. Hasil penelitian menunjukkan bahwa media supermarket sangat valid (83,31%), sangat praktis (81,34%), dan sangat efektif (85,88%) dalam meningkatkan pemahaman siswa terhadap bilangan cacah. Temuan ini memberikan kontribusi terhadap pendekatan pembelajaran kontekstual serta mendukung penerapan Kurikulum Merdeka. Media ini berpotensi diadaptasi lebih luas di sekolah dasar untuk memperkuat kompetensi numerasi siswa. Penelitian selanjutnya disarankan untuk memperluas cakupan sampel dan menggunakan pendekatan kuantitatif maupun metode campuran.
