PENINGKATAN PEMAHAMAN KONSEP GRADIEN DAN TURUNAN PARSIAL MELALUI MODEL PROBLEM BASED LEARNING
type: item
description: Understanding gradients and partial derivatives is an essential competence in multivariable calculus courses. However, many students still experience difficulties in conceptual and applicative understanding. This study aims to improve students’ understanding of gradient and partial derivative concepts through the implementation of the Problem Based Learning (PBL) model. This research employed classroom action research conducted in two cycles involving second-semester mathematics education students. Data were collected through concept understanding tests, observation sheets, and student response questionnaires. The results showed an improvement in students’ conceptual understanding, indicated by increased average test scores and higher student participation during learning activities. Therefore, the Problem Based Learning model is effective in enhancing students’ understanding of gradients and partial derivatives in multivariable calculus courses.

ANALISIS KEMAMPUAN BERPIKIR KREATIF MATEMATIS SISWA MELALUI MODEL REALISTIC MATHEMATIC EDUCATION (RME) BERBANTUAN WIZER.ME
type: item
description: This study aims to analyze students’ creative thinking skills and identify the factors that influence these skills in mathematics learning. A qualitative approach was used with the Realistic Mathematics Education (RME) model. The research involved 30 seventh-grade students from Class VII A. Data were collected through creative thinking tests and documentation, with the tests administered door to door. The results show that the average level of students’ creative thinking ability was 28.13%, categorized as moderate. Further analysis indicates that students in the high and medium groups did not face significant barriers related to factors affecting creative thinking, whereas those in the low group experienced difficulties in intrinsic motivation and prior knowledge. These obstacles limited their ability to generate ideas and solve problems creatively. The findings suggest that the RME model can support the development of creative thinking skills, although additional support is needed for students with low motivation and limited conceptual understanding.

PENINGKATAN KEMAMPUAN BERPIKIR KRITIS SISWA MENGGUNAKAN MODEL PROBLEM BASED LEARNING BERBANTUAN QUIZIZZ
type: item
description: This study aims to determine the effectiveness of the Problem-Based Learning (PBL) model in improving students’ mathematical thinking skills on the Exponent topic among Grade X students at SMA Negeri 1 Simpang Empat in the 2024/2025 academic year. This quasi-experimental research employed a pre-test–post-test control group design with two classes: an experimental class receiving PBL instruction and a control class taught through conventional learning. The average pre-test scores of the experimental and control classes were 69.11 and 66, respectively. After the learning intervention, the average post-test score of the experimental class increased significantly to 84.61, while the control class achieved only 57.37. Statistical analysis using the t-test revealed that the calculated t-value (t_hitung = 4.42) exceeded the critical t-value (t_tabel = 1.67), indicating a significant difference between the two groups. These findings demonstrate that the PBL model has a positive and significant effect on enhancing students’ mathematical thinking skills in Exponent material. Therefore, PBL can be considered an effective alternative instructional approach for mathematics learning at the senior high school level.

TRANSFORMASI LKPD DIGITAL: PENERAPAN PROBLEM BASED LEARNING BERBANTUAN LIVEWORKSHEETS DI SMP
type: item
description: This study is driven by the necessity to create modern and relevant educational materials tailored to the demands of contemporary learning in the digital age. The objective of this research is to develop a Problem-Based Learning (PBL)-oriented E-Worksheet (E-LKPD) focused on two-dimensional shapes for seventh-grade students at SMP Negeri 7 Kisaran, ensuring it is valid, practical, and effective. A Research and Development (R&D) method is utilized for this study. The Thiagarajan model, often referred to as the 4-D Model, serves as the guiding framework, comprising four phases: define, design, develop, and disseminate. The tools used in this research consist of validation forms, questionnaires for both teachers and students, and tests to assess conceptual understanding. According to the evaluations from the validators, the E-LKPD achieved a final validity score of 92%, which is considered highly valid. The practicality, determined by the feedback from teachers and students, scored 93%, indicating it is very practical. The effectiveness of the E-LKPD, assessed through the conceptual understanding test results, reached 88%, categorizing it as highly effective. From these results, it can be inferred that the PBL-based E-LKPD supported by Liveworksheets on two-dimensional shapes for seventh graders is indeed valid, practical, and effective.
