Penerapan Model Pembelajaran Discovery Learning Pada Materi Operasi Hitung Matriks
Full text linkThe learning process occurs naturally in student learning activities and understanding the concepts studied. Generally, the process of delivering mathematical concepts by teachers focuses more on conventional methods, with teachers dominating the learning process leading to a lack of student involvement. Students are passive in learning, making it difficult for them to understand and build mathematical concepts, and students only memorize concepts without understanding them. This causes students not to know how to form, use, and communicate with the material they will learn in everyday life. Therefore, active learning is needed, one of which is applying the discovery learning model. The Discovery learning model is a learning process in which students are not presented with lessons/teaching materials in their final form. However, students must carry out various activities to collect information, categorize, analyze, integrate, organize materials and make conclusions that lead to discovery. The concept of the material being studied. This study aims to determine how students' activities and responses to the discovery learning model on matrix arithmetic operations in Year 12. Data were obtained from observing student activities through assessment rubrics and response questionnaires. The results of this study indicate that the student's activity during the learning process is good, and the student's response to the discovery learning model on matrix arithmetic operations is positive

Kemandirian Belajar Siswa SMP melalui Model Problem Based Learning (PBL)
Full text linkAbstract. Learning autonomy of Indonesian students is relatively low because, during the learning, the teacher directly explained the materials and solved the example problem without involving the students. This situation led to students being less engaged and independent. Therefore, we need an effort to improve student learning autonomy; one of them is using the Problem Based Learning (PBL) learning model. This study was aiming at determining the learning autonomy of students who were taught using the PBL learning model and those learned in conventional learning. This study was an experimental study with a pre-test post-test control group design. The population were all Year 7 students of one of the junior high schools in Banda Aceh, and two classes were selected as the samples randomly. The instrument was a student learning autonomy questionnaire. Data were analysed using t-test and two-way ANOVA to examine the differences in the improvement of students between levels. The results revealed that the students learning autonomy in mathematics during the learning with the Problem Based Learning (PBL) model was better than their counterparts. There was also no interaction between the Problem Based Learning (PBL) learning model and student level (high, medium, low) on student learning autonomy.Keywords: Students Learning Autonomy, Problem Based Learning (PBL) Model
