Abstract

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.

Abstract

This study is motivated by the lack of creative thinking skills of students in learning mathematics as well as one-way learning patterns from the teacher. The interview results confirmed that the creative thinking ability of students of SMA Negeri 1 Langke Rembong class XI MIPA is still relatively low. Therefore, the purpose of this study is to improve the creative thinking ability of students in class XI D SMA Negeri 1 Langke Rembong by applying the STAD type cooperative learning model and open-ended approach assisted by interactive video on trigonometric function material. The type of research used in this study is Classroom Action Research referring to the Kemmis & Mc Taggart model which is carried out in 2 cycles, where each cycle consists of 4 stages, namely: 1) Planning, 2) Implementation, 3) Observation, and 4) Reflection. The data collection techniques were observation, tests, and documentation while the data analysis was descriptive and qualitative. The results showed that the percentage of creative thinking ability of students in the innovative category of 7.14% in cycle 1 increased to 70.37% in cycle 2 of the 27 students' test results analyzed. The application of this learning approach and media learning model also increased the student activity score from 83.5 in cycle I to 100 in cycle II and the teacher activity score increased from 95 to 100 in cycle II. Thus, the application of the STAD-type cooperative learning model with an ended approach assisted by interactive video can improve the creative thinking ability of students of class XI D SMA Negeri 1 Langke Rembong on trigonometric function material.

Abstract

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.

Abstract

This study aims to improve students' mathematics learning outcomes by implementing the discovery learning model assisted by quizizz. The subjects of the study were 30 eighth-grade students from SMP Negeri 1 Labuhan Haji, Lombok Timur. The research used a classroom action research (CAR) method conducted in two cycles. Each cycle consisted of planning, action, observation, and reflection stages. The results showed a significant improvement in learning outcomes from the pre-cycle to cycle I and cycle II. In the pre-cycle, only 23.33% of students achieved mastery, with an average score of 45.31. After the implementation of the discovery learning model assisted by Quizizz in cycle I, the mastery percentage increased to 56.70%, and in cycle II, it reached 90.00% with an average score of 86.21. Based on these results, it can be concluded that the implementation of the discovery learning model assisted by quizizz is effective in improving students' mathematics learning outcomes.
