Abstract

This study aims to use constructivist principles to find out how misunderstandings arise when solving arithmetic problems among students of grade 7 C of SMPN 2 Ciruas and to identify the factors responsible for them so that this problem can be presented to students and teachers as a reference for more effective learning. The subjects of this study were students of grade 7 C with high, medium and low comprehension skills. This study is qualitative and uses descriptive methods. It uses test instruments in the form of AKM sample questions and interview guides related to constructivist principles. The data analysis techniques used are data reduction, data display and inference. The results of this study explain the misunderstandings that students, especially those with low comprehension, experience when presented with numerical problems in a mathematical format. According to constructivist theory, factors that cause misunderstandings include: 1) lack of additional study time; 2) poor prior knowledge; 3) lack of understanding of the problem; 4) not taking an active role in the classroom; and 5) incorrect interpretation of the problem.

Abstract

Indonesia is known as a country with cultural diversity, one of which is the traditional house, a symbol of each tribe and region. In its implementation, the Joglo house is only used as a residence and a place to protect against exposure to sunlight. Still, after exploring it in more depth, the structure of the traditional house can be used as learning material in the field of education. One field of education that can study culture through the structure of conventional house buildings is mathematics. Learning mathematics that includes culture can help students improve their understanding of abstract mathematics. However, not many mathematics lessons incorporate culture into the material. So, this research aims to explore Banyumas Joglo houses regarding geometric concepts. The type of research used is qualitative research with an ethnographic approach. Data collection methods include observation, documentation and interviews. The data analysis consists of data reduction, data presentation, and conclusion. This research shows that the Banyumas Joglo traditional house is an example of a conventional house rich in ethnomathematics, where elements of traditional culture contain mathematical knowledge in the form of geometric concepts.

Abstract

Integrity has had plenty of impact on human civilization development, especially in the development of human technology. The primary role of an integral is not well supported by students’ skill in solving integral problems. Due to this fact, mathematics educators need solutions. Artificial Intelligence (AI) integration is one of the solutions that mathematics educators can choose. This qualitative descriptive research aims to explore students' mistakes in solving integral problems with the help of  Photomath. This research will describe student mistakes and explain how students realize mistakes during rework assisted by Photomath. This research involved ten mathematics students who joined an integral course at a university in Indonesia. The errors were analyzed based on Newman error analysis. Errors found based on research results include (1) Comprehension and transformation, (2) Process skills, and (3) Encoding. This research found that comprehension errors have implications for transformation. Students who make comprehension errors will cause transformation errors. Meanwhile, the subject's errors in the previous stage affect the encoding stage. Apart from the errors already mentioned, errors were also found due to carelessness, which was not a significant part of Newman's error analysis.

Abstract

A person's capacity to make choices and find solutions to issues in life is significantly influenced by their self-efficacy and numeracy literacy level. Using technology in education is one way to try to make it better. One learning approach that uses technology is the Moodle-assisted Problem-based Learning (PBL) model, which blends the PBL paradigm with Moodle-assisted learning. This research aims to: (1) evaluate the impact of a Moodle-assisted problem-based learning model on students' numeracy literacy; and (2) investigate the impact of students' self-efficacy on their mathematical numeracy literacy. This study uses a mixed method approach, with more quantitative data than qualitative data and an explanatory sequential design. The pupils in grade VII at SMPN 5 Cimahi comprise the study's population. A simple random sample method was used to choose the quantitative data. Qualitative data was collected based on the high, medium, and low categories of student self-efficacy. Methods for quantitative data analysis using parametric statistics, including regression, classical completeness, and mean tests. Techniques for analyzing qualitative data include data reduction, presentation, and conclusion drawing. The study's findings demonstrated that (1) Moodle-assisted PBL successfully raised students' literacy in mathematics and numeracy. (2) In Moodle PBL learning, there was a relationship between students' self-efficacy and numeracy literacy

Abstract

This study aimed to improve students' numeracy literacy skills by implementing the Problem-Based Learning model with the Teaching at The Right Level approach. The study was conducted in Class X DPIB 1 SMKN 1 Kota Madiun, Kartoharjo District. Thirty-six students participated in this study, with 30 males and six females as samples. In the 2023-2024 academic year, the research period took place from February to May, beginning the second semester. The study was conducted in two cycles, with four sessions, each meeting lasting 2 JP (2 x 45 minutes). Class X DPIB 1 students had an average numeracy literacy ability score of 55.50 in the Cycle 1 evaluation. This indicates that there is still considerable room for improvement. In addition, most students have not met the minimum required level of completeness, as seen from the percentage of classical completeness, which only reached 36.11% (13 students scored ≥ 75). Meanwhile, the analysis of the data from cycle 2 showed that there were no students in the inferior category, two students in the poor category, five in the pretty good category, twenty-two in the excellent category, and seven in the outstanding category. The implementation of cycle 2 showed a significant increase, where the average score of numeracy literacy skills of class X DPIB 1 students increased to 72.94, and the percentage of classical completion also increased to 58.33% (21 students scored ≥75). Students' numeracy literacy skills can be improved by combining the Problem-Based Learning model with the Teaching at The Right Level Approach.

Abstract

The purpose of this study is to determine whether Quiziz media has an impact on sixth-grade elementary school pupils' interest in learning. This study uses an experimental pretest-posttest one-group design. The population in this research consists of all sixth-grade students at SD Kartika 1-9 Pekanbaru, totalling 21 students. The sampling technique is saturation sampling, where the entire population is used as the sample. An interest questionnaire with 20 questions determines students' learning interests. Descriptive and inferential statistical analysis are the methods of data analysis that are employed. According to the findings of the descriptive study, the average score on the pretests was 58.19 before the use of Quizizz-assisted media (pretest) and had risen to 66.05. In the meantime, a Sig(2-tailed) value of 0.002 was derived based on the results of inferential analysis, where the value was less than 0.05 (0.002 < 0.05). Consequently, it might be said that "Hypothesis Accepted" or that H0 is rejected and H1 is accepted. Therefore, it may be concluded that a factor influences the rise in learning interest among sixth-grade elementary school pupils.

Abstract

This research aims to determine whether or not mathematical literacy skills influence students' problem-solving abilities. The research method used is quantitative research with a regression approach. The subjects were 64 class XI students, who were selected using cluster random sampling from a population of 133 students. Data was obtained using the Mathematical Literacy Ability Questionnaire and Mathematical Problem Solving Ability Test Instrument. Data were analyzed using appropriate test statistics, namely the Chi-Square and Simple Linearity Test as prerequisite tests. Hypothesis testing is carried out in stages: (1) Pearson's Product Moment Correlation analysis, (2) Correlation Significance Test, and (3) Coefficient of Determination Test. After the data analysis, it was concluded that mathematical literacy abilities (X) positively influenced mathematical problem-solving skills (Y). This is proven by the calculation results of Sig.=0.000 < Sig.α =0.05 and the coefficient of determination value of 0.906. This means that mathematical literacy skills strongly influence mathematical problem-solving abilities, and the effect is 90.6%. The regression equation Y = -53.813 + 0.8189X shows that for every additional unit of variable X, the Y value or students' mathematical problem-solving ability increases by 0.8189.

Abstract

Despite the growing interest in contextualizing mathematics education, research integrating Qur’an contexts into mathematics instruction remains limited. Prior studies have largely concentrated on conventional teaching methods, Qur’an-centered instruction, or Problem-based Learning (PBL) as independent approaches. This study addresses a critical gap by integrating Qur’an contexts into integer learning, supported by problem-based learning and facilitated through a technology-enhanced Electronic Student Worksheet (E-SW). The primary objective of this study is to design and assess the reliability and applicability of a Quran-based E-SW using the PBL framework for teaching integers to 7th-grade junior high school students. Employing a Research and Development (R&D) methodology with the ADDIE development model—comprising analysis, design, development, implementation, and evaluation phases—this research utilizes expert validation sheets and student practicality questionnaires as instruments. The study sample consists of 7th-grade students from SMP IT LHI Yogyakarta, with class 7B selected through purposive sampling. Validation results indicate that the E-SW meets established validity criteria, with scores from subject matter and media experts reaching 99 and 91, respectively, both classified as "Good." Practicality testing revealed positive student responses, yielding a practicality score of 61, categorized as "Practical." Furthermore, a paired sample t-test demonstrated a statistically significant improvement in student performance between pretest and posttest results, with a significance (2-tailed) value below 0.05 and an average N-Gain score of 0.4391, which is classified as moderate. These findings suggest that the Quran-based E-SW, structured around the PBL model, effectively enhances students' problem-solving abilities and is suitable for educational use.
