The purpose of this study is to determine whether the mathematical conceptual understanding ability of 11th grade MIPA students at SMAN 1 Camapalagian, taught using the Novick learning model, is higher compared to those taught using the direct learning model. This research is a quasi experiment with a nonequivalent control grup design. The study was conducted at SMAN 1 Campalagian during the academic year 2023-2024, with class XI MIPA 2 designated as the experimental group and class XI MIPA 1 as the control group. Data collection techniques involved administering tests on mathematical conceptual understanding ability and observation sheets. Data analysis techniques included descriptive and inferential analysis using SPSS 23. Descriptive statistical analysis showed that the average pretest score for the experimental group was 15,84 while for the control group, it was 15,17. The average posttest score for the experimental class was 78,72, while the average posttest score for the control class was 65,09. Hypothesis testing using an independent sample t-test yielded a significance value of 0,00000045 < 0,05 , therefore, the null hypothesis (H₀) was rejected, and the alternative hypothesis (H₁) was accepted, indicating that the mathematical conceptual understanding ability of 11th grade MIPA students at SMAN 1 Campalagian, taught using the Novick learning model, is higher compared to those taught using the direct learning model.

This research discusses the design and implementation of GeoGebra media and Student Worksheets (LKPD) for three-dimensional material. The main focus is to explore the potential use of media, such as 3D simulations, learning videos, and mathematical modeling applications, in increasing students' understanding of complex concepts. This research aims to analyze the benefits of using media in LKPD, including increasing student involvement, facilitating abstract understanding, and developing critical thinking skills. The research method used is Research and Development (R&D), which involves the needs analysis, design, development, implementation and evaluation stages. The research subjects consisted of 30 students taking the Mathematics Teaching Materials course. Data was collected through a questionnaire on student responses to the media used in the LKPD. The research results show that the use of media in LKPD significantly increases understanding of three-dimensional concepts. In addition, students responded positively to the use of media, which was considered to help visualize concepts and increase interest in learning. Media implementation strategies in LKPD, such as demonstrations, group assignments and class discussions, have proven effective in overcoming the challenges of three-dimensional mathematics learning. Thus, media integration in LKPD is recommended as an effective strategy to increase students' understanding and involvement in mathematics learning.
