Abstract

This study aims to analyse the level of students' understanding of concepts in Statistics courses and examine the impact of applying presentation methods in the learning process. The study uses a descriptive approach and was conducted in the Sharia Accounting class in Semester 3 at UINSU Medan in the 2024/2025 academic year. The research subjects were students in class AKS 3B, while the research object was a questionnaire designed to measure students' conceptual understanding of statistics material. The data obtained were analysed descriptively to describe the trends in students' conceptual understanding levels. The results showed that the average level of students' conceptual understanding ranged from 2.41 to 2.71. This range falls within the neutral category, i.e., between 2.1 and 3, indicating that students' conceptual understanding of statistical material through the presentation method is not yet fully optimal and still needs to be strengthened through more varied learning strategie

Abstract

The purpose of this study was to determine whether there was an effect of the implementation of the Collaborative Problem-Solving learning model assisted by Desmos on students’ mathematical problem-solving ability in quadratic function material for class X at SMA Negeri 1 Aek Kuasan in the 2025/2026 academic year. This research used a quasi-experimental method with a two-group pretest-posttest design. The population in this study consisted of all class X students, which were divided into six classes. The sample of this study consisted of two classes, namely class X-2 and class X-3, selected using cluster random sampling. Class X-2 was used as the experimental class using the Collaborative Problem-Solving learning model assisted by Desmos, while class X-3 was used as the control class using the direct learning model assisted by Desmos. After the learning process was completed, the posttest results showed that the average score of the experimental class was 80.027, while the control class was 67.583. The t-test result showed that t_hitung=6,722>t_tabel=1,994, therefore H_0 was rejected and H_a was accepted. Thus, it can be concluded that there was an effect of the Collaborative Problem-Solving learning model assisted by Desmos on students’ mathematical problem-solving ability in quadratic function material for class X at SMA Negeri 1 Aek Kuasan in the 2025/2026 academic year.
