Abstract

The implementation of a realistic mathematical approach to learning the material of Pythagoras's theorem is carried out to encourage students to understand the material through everyday life so that the problems in the classroom gradually end in the secondary school. A realistic mathematical approach is an approach to learning mathematics that involves students to be more active by discussing in solving a problem or issue by connecting to daily life. The subjects in this study were 32 students of class VIII-3 SMP Negeri 2 Medan. This research is a Class Action Research (PTK) consisting of 2 cycles, with each cycle consisting from 2 meetings. after learning on cycle II by performing improvements from cycle I. Improvement is the planning of the student activity sheet that emphasizes the solution of issues with steps or indicators of problem-solving ability, because there are still many students who are not accustomed to the steps to solve problems. As for other improvements, namely planning activities in real life, in the 2nd cycle students solve the real problems of everyday life that students do. The researchers also provide motivation and reinforcement in learning to students to be active in group discussions and presentation of group work results to other groups, so that the interest of students in learning mathematics increases.

Abstract

The aim of this research is to develop learning media using Articulate Storyline 3 that are valid, practical, and effective to improve students' ability to understand flat plane topics. The study was carried out at MTSS AL KAROMAH BERASTAGI. The subjects of this research were students of class VII-A. This research is research and development (R&D) using the ADDIE Model. The data collection technique uses a questionnaire assessment sheet for material experts, teaching material experts, learning practitioners and student responses. The results showed that learning media using Articulate Storyline 3 obtained an average percentage of 93.47% with the criteria of "very valid" according to the assessment of teaching materials experts and based on media material experts obtained an average percentage of 77.5% with the criteria " very valid". Based on the practice of learning carried out by the mathematics teacher getting 91,4% with the "very practical" criteria. Based on the effectiveness assessment of the 20 students, they got an average percentage of 88.90% with the criteria of "very effective".

Abstract

This study aims to identify the difficulties faced by tenth-grade students in understanding enumeration rules and to find effective learning solutions. The research method used was descriptive qualitative, with 33 tenth-grade students of SMA Negeri 1 Percut Sei Tuan as subjects. The instruments used included a diagnostic test in the form of National Examination questions 7-11 on permutations and combinations, interviews with mathematics teachers, and classroom observations. The results showed that the majority of students (50%) were in the moderate understanding category, understanding the basic concepts but frequently making procedural errors. Thirty percent of students were in the low understanding category, having difficulty distinguishing between addition and multiplication rules and applying the concepts to word problems. The main obstacles identified included a lack of mastery of basic concepts, difficulty determining solution steps, a lack of varied practice questions, and limited interactive learning media. Recommended solutions include the use of visual media such as tree diagrams and tables, a contextual approach to everyday life problems, collaborative learning, and the provision of additional tutoring.

Abstract

Using Newman's Error Analysis (NEA) as a framework, this study will examine the many ways in which MAN 3 Medan students blunder while answering problems involving logarithms and exponentials. A total of thirty-one MIPA class X students served as subjects for this qualitative descriptive study. Essay tests, interviews with math instructors, and records of student work all contributed to the data set. Data analysis involves reducing, presenting, and making conclusions while triangulating sources to ensure the data is legitimate. According to the research, the two most common points of mistake are when people are trying to grasp the issue and when they are trying to convert it. This is because pupils have a hard time grasping the characteristics and fundamental ideas of logarithms and have a habit of rote memorization rather than critical thinking. Other factors that also affect include the lack of utilization of learning media and low student learning motivation. After being given discussion-based learning and interactive media, the post-test results showed an increase in comprehension and a decrease in conceptual errors. This research recommends that teachers should emphasize student-centered learning by strengthening basic concepts and implementing contextual problem-solving strategies.

Abstract

This study aims to analyze students' understanding and difficulties in probability in grade XII of SMA Negeri 1 Tanjung Morawa and identify the contributing factors. The research method used is descriptive with quantitative and qualitative approaches. Quantitative data were obtained from the results of the problems given to students, then analyzed to determine the level of understanding, types of errors, and the percentage of difficulties experienced. Meanwhile, qualitative data were obtained through interviews with subject teachers to deepen information regarding the obstacles faced by students and the learning strategies implemented. The results showed that most students experienced difficulties in determining the sample space, applying probability formulas, and interpreting calculation results. Contributing factors include limited understanding of basic concepts, a lack of variety in practice questions, and learning that still focuses on procedures. Based on these findings, the researcher offers solutions in the form of contextual learning, conceptual reinforcement through class discussions, and the provision of step-by-step practice questions with teacher guidance. This research is expected to contribute to teachers in improving the effectiveness of probability learning in schools.

Abstract

This study aims to describe the improvement of mathematical problem-solving skills after applying the realistik mathematics learning assisted by digital media of class VIII students of SMP Dharma Patra Sei Lepan for the 2022/2023 academic year. The subjects in this study were 32 class VIII-A students of Dharma Patra Private Middle School. Data collection techniques used were teacher observation sheets, tests of mathematical problem-solving skills, and documentation. This research is a classroom action research (PTK) which consists of 2 cycles, each cycle consisting of 2 meetings. Before taking action, first given the initial test and at the end of each cycle is given a test of students' mathematical problem-solving abilities. The test results of students' mathematical problem-solving abilities increased from the initial test, cycle I, and cycle II. In the classical pre-test, 3 students (9.38%) passed and the average pre-test ability was 49.12% with a very low level of ability. In the first cycle test, there was an increase classically, 17 students (53.13%) completed and the average ability test obtained 69.01% with the ability level in the medium category. Then the second cycle test also experienced an increase in classically obtained 28 students (87.5%) completed and an average ability obtained 81.05% with a high level of ability category. Thus it can be concluded that the application of realistik mathematics learning assisted by digital media can improve the mathematical problem-solving skills of class VIII students of SMP Dharma Patra Sei Lepan.
