Abstract

Mathematical literacy-based problems require the ability to read, interpret and connect contextual information with mathematical concepts, which is often a challenge for students. This difficulty is especially evident in modulo congruence material which requires an understanding of number concepts and mathematical logic. This study aims to analyze students' errors in solving mathematical literacy problems related to modulo congruence material. The research subjects were ten grade XI students from one of the high schools in Gowa Regency who were selected by purposive sampling. The method used was a written test to identify the types of errors, as well as in-depth interviews to explore the causes. The results showed that students had difficulty in understanding important information from the problem, translating it into a mathematical model, and composing the solution steps systematically. The conclusion of this study shows that learning interventions are needed that focus on strengthening context understanding, practicing reading problems critically, and habituation to develop coherent solution strategies. In addition, gradual integration of mathematical literacy exercises needs to be done so that students are able to develop mathematical thinking skills as a whole.

Abstract

The Problem-Based Learning (PBL) model has been widely applied as an alternative in improving students' mathematical literacy, especially in the midst of low literacy achievement at various levels of education in Indonesia. Through a systematic review of 36 empirical articles published between 2016 and 2025, it was found that PBL consistently has a positive impact on reasoning skills, problem-solving, and the application of mathematical concepts in real-life contexts. The success of this approach is also influenced by various contextual factors, such as students' thinking styles, the role of teachers in facilitating learning, and the use of digital technology. The findings confirm that PBL is an effective learning strategy in building mathematical literacy, as well as making an important contribution for educators and policymakers in developing a more contextual, adaptive, and meaningful learning approach.

Abstract

Abstract Problem-solving skills are important for students to be able to overcome problems in mathematics and everyday life. However, 12th grade students at SMK Negeri 2 Kotabumi still lack adequate problem-solving skills. This study aims to explain how male and female students solve problems in statistics with the topic of single data mean at SMK Negeri 2 Kotabumi. This study employs a descriptive qualitative method. The research subjects consist of two male students and two female students in the 12th grade of the Computer Networking Technology program, selected using purposive sampling. The research instruments include the researcher themselves, a test instrument, and an interview guide. Data collection methods included tests and interviews. To verify data validity, triangulation of time, research persistence, and member checks were used. Data analysis methods included data reduction, data presentation, and conclusion drawing. The results of this study indicate that male students successfully completed each stage of problem-solving according to Polya. The process begins with understanding the problem, formulating a solution plan, implementing the plan, and finally checking the answer. Female students successfully carried out three of the four problem-solving stages according to Polya, namely understanding the problem, designing a solution, and implementing the plan. However, in the stage of checking the answer, female students often skipped this step.

Abstract

Evaluating students' mathematical communication ability is crucial for understanding their ability to convey mathematical ideas logically, precisely, and in a structured manner. A good evaluation instrument is the primary tool for measuring this aspect objectively and purposefully. This research is motivated by the low mathematical literacy achievement of Indonesian students in the 2018 PISA survey, which indicates weak mathematical communication ability. This study aims to analyze students' mathematical communication ability from a gender perspective. This study used a quantitative method with a survey design. The survey type used was a cross-sectional survey design. The results showed that female students had higher average scores than male students, but the ANOVA test produced a significance value of 0.621 (> 0.05), indicating no significant difference. This finding shows that mathematical communication ability is more influenced by individual factors. The implication is that teachers need to use adaptive learning approaches and evaluation instruments that address individual student needs.

Abstract

Mathematics is often perceived as a difficult, anxiety-inducing, and challenging subject by many students, which in turn affects their learning achievement. Several studies have shown that students frequently experience mathematics anxiety and low self-confidence when engaging with mathematical tasks, leading to decreased performance and motivation to learn. The purpose of this study was to examine and provide evidence on the level of students’ perseverance in learning mathematics. The findings are expected to help teachers and schools develop strategies that foster students’ perseverance, enhance engagement, and ultimately improve mathematics achievement. This research is descriptive quantitative with a survey approach. This research was conducted in March 2025. The population in this study were all students in grades IV, V and VI at SD Negeri 23 Jeppe'e, Bone Regency with a total of 60 students. The sample was selected by random sampling with a sample size of 30 students. The research instrumentused was the Mathematics Learning Persistence Scale, which consists of 28 valid statements with a Cronbach's alpha coefficient of 0.78. Data collection was done by distributing math learning perseverance scale and data analysis technique was descriptive statistics. The results of the study show that the perseverance of students in learning mathematics at SD Negeri 23 Jeppe, Bone Regency, is in the moderate category with an average score of 85.8. This shows that most students have a fairly good endurance in dealing with math learning difficulties, but there is still a tendency to give up easily when encountering challenging math problems. Teachers are advised to design learning activities that encourage students' perseverance, for example by using the Problem-Based Learning or Project-Based Learning approaches, which require students to repeatedly solve problems until they succeed.

Abstract

Students’ mathematical problem-solving ability remains a challenge in secondary education, particularly due to the dominance of teacher-centered conventional methods. This study aims to analyze the effectiveness of the Problem Based Learning (PBL) model in relation to students’ learning styles (visual, auditory, and kinesthetic) on mathematical problem-solving skills. A quantitative approach with a quasi-experimental design was employed, involving 60 eleventh-grade students divided into experimental (PBL) and control (conventional) groups. Research instruments included a problem-solving test and a learning style questionnaire, with data analyzed using Two-Way ANOVA. The results revealed that: (1) there were significant differences in problem-solving abilities based on students’ learning styles; (2) the PBL model was more effective than the conventional model; and (3) a significant interaction existed between learning models and learning styles in influencing students’ problem-solving performance. Therefore, implementing PBL in alignment with students’ learning styles is proven to enhance the effectiveness of mathematics instruction in secondary schools.

Abstract

Mathematics, especially the topic of probability, is often considered abstract, complicated, and boring by students, which leads to low interest in learning. This condition is exacerbated by the use of monotonous conventional teaching methods. This study aims to: (1) provide an overview of the feasibility of developing an educational game titled “Petualangan Matematika” based on smartphones using the Scratch platform for the topic of Probability, (2) explain the validity of the educational game as assessed by expert validators, and (3) describe the practicality of the smartphone-based educational game in supporting the learning process of mathematics, specifically on the topic of Probability. The research employed the Research and Development (R&D) method by adopting the ADDIE development model, which consists of five systematic stages: Analysis, Design, Development, Implementation, and Evaluation. The visual design of the game was created using Canva, while the development of the educational game itself was carried out using the Scratch platform. The final product is an educational game that can be accessed and played on smartphone devices. The research subjects consisted of 27 students, divided into two groups: a small group of 5 students who participated in the readability test, and a larger group of 22 students who took part in the practicality test. The instruments used to assess both validity and practicality were questionnaires utilizing a Likert scale. The data analysis techniques involved evaluating the results of the readability and practicality tests. The results of the study concluded that: (1) the product, a smartphone-based educational game titled “Petualangan Matematika” for the topic of Probability, is categorized as highly feasible for use in learning activities; (2) the validity level of the game is very high, as evidenced by expert assessments: media expert validation yielded a score of 81.25%, while two subject matter experts provided scores of 93.75% and 100%, respectively; and (3) the game demonstrated a very high level of practicality, indicated by a 92% score in the readability test conducted with the small group and a 97.125% score in the practicality test with the larger group.

Abstract

This study examines the effect of implementing a GeoGebra-assisted Problem Based Learning (PBL) model on students’ mathematical problem solving abilities. It was motivated by students’ low initial performance in solving problems, as indicated by pretest scores below the minimum mastery criterion, highlighting the need for innovative, technology integrated instruction. This study adopted a quantitative method employing a quasi experimental design with a pretest posttest control group. The participants were 42 seventh grade students at SMP Negeri 2 Abung Surakarta, with 22 in the experimental group (Class VII A) and 20 in the control group (Class VII B), selected via purposive sampling. The intervention spanned five sessions on the topic of squares, with the experimental group receiving GeoGebra assisted PBL instruction and the control group receiving conventional teaching. Data were collected through problem solving tests and analyzed using normality and homogeneity tests, N-gain analysis, and independent samples t-tests. Results showed that the experimental group achieved a higher average N-gain (0.608) than the control group (0.444), and the t-test indicated a significant difference , ? = 0.05). These findings confirm that the GeoGebra assisted PBL model effectively enhances students’ mathematical problem solving skills and supports the use of technology integrated learning in teaching squares at the junior high school level.
