Abstract

Communication is one of the important skills that students must have in mathematics. Engaging in communication activities helps provide an understanding of mathematical communication skills to students. However, in reality, students' mathematical communication skills are still in the low category. Therefore, a more interactive learning method is needed. This study was conducted to analyze the effectiveness of the Realistic Mathematics Education (RME) approach in improving mathematical communication skills.The method used in this research is a literature review with inclusion and exclusion criteria focusing on studies containing quantitative or qualitative data. The data collection technique involved gathering relevant National and International Journal articles published between 2019 and 2023. From the numerous articles found, researchers selected 21 articles related to this study. The data processing technique applied in this study examined the effectiveness of using Realistic Mathematics Education (RME)  to improve communication skills in the collected articles. The results showed that RME is an effective learning approach for improving students' mathematical communication skills. In addition to Realistic Mathematics Education (RME), classroom learning can be enhanced with various media, such as Audio Visual Media or Learner Worksheets (LKPD). This approach makes classroom learning more interactive and receives positive responses from students, helping them understand the material better by expressing mathematical ideas through oral and written language and making arguments with confidence.

Abstract

Students frequently respond to problems posed by their instructors through trial and error, without first grasping the underlying concepts. They often perceive the problems as entirely new and unrelated to their previous experiences, leading to a lack of confidence and reinforcing the belief that mathematics is a difficult subject. Consequently, their responses are often incorrect or incomplete. The objective of this study is to describe the mathematical problem-solving abilities of grade XI students on the topic of sequences and series in one of the schools in Bekasi Regency. This research employed a descriptive qualitative method, with data analysis techniques based on the interactive model developed by Miles and Huberman. The subjects of this study were 25 grade XI students selected using purposive sampling. The test instrument consisted of problem-solving tasks, while non-test data were obtained through interviews. The results indicate that students' mathematical problem-solving abilities fall into three categories: 4% of students demonstrated high problem-solving skills, 4% were in the medium category, and 92% were classified as low. A detailed analysis of problem-solving indicators reveals that: (1) in understanding the problem, many students struggled to identify the given information and the goal of the problem; (2) in devising a solution plan, most students failed to select an appropriate strategy, often guessing rather than structuring a logical approach; (3) in executing the plan, students in the low category frequently made calculation errors and misapplied formulas; and (4) in reflecting on the solution, very few students revisited their answers to verify accuracy or consider alternative methods. These findings suggest that students’ mathematical problem-solving abilities remain relatively low, with significant gaps in comprehension, planning, execution, and reflection. Strengthening these aspects through targeted interventions is necessary to enhance students’ overall problem-solving skills.

Abstract

Problem-solving ability is an essential skill that must be possessed by students, especially in Vocational High Schools (SMK), in order to apply the concepts learned in real situations. However, many students have difficulty in identifying and solving mathematical problems because the learning method is still centered on the teacher and the minimal use of interactive learning media. This study aims to analyze the mathematical problem-solving ability of vocational high school students whose mathematics learning uses the Problem Based Learning model assisted by interactive media canva and quizizz compared to those who use regular learning. This study uses a quasi-experimental method with a Nonequivalent Control Group Design. The research sample consisted of 64 grade XI students of SMKN 1 Cariu, which were divided into an experimental class (32 students) who received learning using PBL assisted by interactive media Canva and Quizizz, and a control class (32 students) who used regular learning methods. Data collection was carried out through problem-solving ability tests (pretest and posttest), questionnaires and observations. Data analysis using inferential statistics, namely the average difference test with N-Gain as a measure of learning outcomes, and thematic analysis for qualitative data. The results of the study showed that the mathematical problem-solving ability of vocational high school students whose mathematics learning used the Problem Based Learning model assisted by interactive media canva and quizizz was better than those who used regular learning.

Abstract

Abstract. The National Examination in Indonesia has been abolished since 2020. Hence, the Indonesian Junior High School (SMP) makes its final examination items for the 9th-grade, and from the results, the school determines success in the course. The final examination has an important role and significant value in making decisions about students' graduation. Therefore, this study is aimed to analyze the Online Final Examination items in one of the public junior high schools in Bandung. The sample was 234 students in grade 9 using their mathematics examination tests, comprising 20 multiple-choice items with 4 options (A-D), while the data processing used Winsteps software with the Rasch modeling technique. Subsequently, the Rasch model results showed an acceptable people separation statistic of 1.54 and poor person reliability at 0.7<0.8. The item separation statistics was in a good category at 2.21, while the reliability at 0.83 was excellent. Although 4 online final examination items were in the fit category, 16 were good and capable of dividing students according to their abilities. They also provided very detailed data about the quality of the items and the ability of each grade 9 student. Since each test item is included in the fit category, this study contributes information on preparing and analyzing the Online Final Examination to teachers.
