Abstract

This study aims to analyze the quality of daily test items and non-test instruments (questionnaires) on Two-Variable Linear Equation Systems in junior high school, in terms of validity, reliability, discrimination power, and difficulty level. The method used was descriptive analysis with 64 eighth-grade students (academic year 2024/2025) as subjects. The findings show that all instruments are valid (essays are very high, multiple-choice questions and questionnaires are high), but the reliability of exam questions (essays and multiple-choice questions) is still in the moderate category. Further analysis of multiple-choice questions shows a predominance of easy difficulty levels (92%) and a number of items (25%) with poor discrimination power, indicating the need for item revision.

Abstract

Developing students’ mathematical reasoning, self-efficacy, and adversity quotient is essential in supporting their academic resilience and problem-solving skills. This study compares the effectiveness of Probing-Prompting (PP) and Problem-Based Learning (PBL) models in enhancing these three domains among junior high school students. A quasi-experimental design with a nonequivalent (pretest-posttest) control-group approach was used. The study involved 56 seventh-grade students from a public junior high school in Yogyakarta, divided into two classes: an experimental group using PP and a control group using PBL. Data were collected using validated and reliable instruments, including mathematical reasoning tests and self-report questionnaires on self-efficacy and adversity quotient. Data analysis employed paired t-tests, independent t-tests, Mann–Whitney U tests, and Hotelling's T² with a significance level of 0.05. Both PP and PBL significantly improved students' mathematical reasoning, self-efficacy, and adversity quotient. However, comparative analyses showed no statistically significant differences in the mean gain scores between the two groups for all three variables: mathematical reasoning (t = 0.829, p = 0.206), self-efficacy (U = 351.50, p = 0.256), and adversity quotient (U = 334.00, p = 0.173). While PP and PBL are both effective, neither demonstrated clear superiority in improving the targeted skills. The short intervention period may have limited the full impact of the PP model. Nonetheless, the findings suggest both models offer valuable strategies for supporting students’ cognitive and non-cognitive development.

Abstract

This study examines the effectiveness of Realistic Mathematics Education, also supported by a website based on ethnomathematics, on the understanding of math concepts among junior high school students. The research method used in this study is quantitative research with a pre-experimental design, one-group pretest-posttest. The sample in the study was 29 students, which was taken from the 8th-grade students of a junior high school in Yogyakarta, picked through cluster random sampling. This study’s instruments were essay tests, which had been validated and proven reliable. The data from the research were analysed by descriptive and inferential statistics, where the inferential statistics included the Normality Shapiro-Wilk test and the One-Sample T-Test. The results indicated a significant improvement in students' understanding of math concepts after using RME through ethnomathematics-based website reach a significant change. This is evidenced by the posttest average value of 82.228, which is far more significant than the Minimum Mastery Criteria value of 75, and 79.31% of the students achieved and exceeded it. These results suggest that including local cultural contexts, batik motifs, and the Borobudur Temple structures in students’ learning process can enhance the students’ conceptual achievement level by strengthening the relationship with the learning process in their daily lives.

Abstract

This study aimed to develop an authentic mathematics assessment for elementary schools in the form of a testlet-based instrument integrated with deep learning principles and the Adiwiyata context within the framework of transformative Islamic education in the Special Region of Yogyakarta. Employing basic research with an embedded mixed-methods design, the development process adapted the Plomp model and the instrument development framework of Oreondo and Antonio. Data were collected through teacher needs surveys, expert validation, readability testing, and field trials involving 462 fifth-grade students from elementary schools and Islamic elementary schools. Quantitative analyses included Content Validity Index (CVI), Aiken’s V, Cronbach’s Alpha, Classical Test Theory (CTT), and Item Response Theory (IRT) using the 2-PL Graded Response Model. The results indicate that the developed instruments meet acceptable psychometric standards, with Aiken’s V values ranging from 0.75 to 1.00 and high internal consistency for both the testlet instrument (Cronbach’s Alpha = 0.845) and the environmental awareness questionnaire (Cronbach’s Alpha = 0.850). Item analysis shows adequate discrimination and a structured progression of difficulty, although one item exhibited low discrimination in the 2-PL GRM, highlighting the importance of IRT-based diagnostics for testlet refinement. Descriptive findings reveal that students demonstrate high levels of environmental awareness, particularly in the knowledge and attitude dimensions, while mathematical achievement remains low on non-routine items. Correlation analysis shows no significant relationship between environmental awareness and mathematical ability. Methodologically, this study contributes a validated and contextually grounded assessment framework that integrates expert judgment, reliability analysis, and complementary CTT–IRT procedures. Theoretically, the findings reconceptualize authentic assessment as a diagnostic bridge rather than a direct causal link between affective values and cognitive performance, demonstrating that environmental concern functions as a potential cognitive resource only when explicitly activated within mathematical tasks.

Abstract

This study aims to: (1) Determine the effect of the discovery learning model with the aptitude treatment interaction strategy on the mathematical concept comprehension and self-efficacy of 10th-grade students at SMA Negeri 3 Tarakan; (2) Determine the effect of the discovery learning model with the aptitude treatment interaction strategy on the mathematical concept comprehension of 10th-grade students at SMA Negeri 3 Tarakan; (3) Determine the effect of the discovery learning model with the aptitude treatment interaction strategy on the self-efficacy of 10th-grade students at SMA Negeri 3 Tarakan. The research population included all tenth-grade students of SMA Negeri 3 Tarakan in the 2024/2025 academic year. The research sample consisted of two classes selected randomly: one experimental class receiving discovery learning with an aptitude treatment interaction strategy and one control class receiving conventional learning. The research instruments consisted of a test measuring mathematical concept understanding on trigonometry material and a self-efficacy questionnaire. The data obtained were tested for prerequisites through normality and homogeneity tests before being analyzed using inferential statistical tests in the form of an independent samples t-test with the assistance of SPSS software version 26.0. The research results show that the implementation of the discovery learning model with the aptitude-treatment interaction strategy has a significant impact on students' mathematical concept understanding and self-efficacy simultaneously, with a significance value of 0.006 < 0.05. Partially, this learning model has a significant effect on students' mathematical concept understanding, with a significance value of 0.018 < 0.05. However, the effect of the discovery learning model with the aptitude-treatment interaction strategy on students' self-efficacy is not statistically significant, as indicated by a significance value of 0.089 > 0.05, even though there is a tendency for increased self-efficacy among students participating in the experimental class learning. Nevertheless, the influence of the discovery learning model with the aptitude treatment interaction strategy on students' self-efficacy is not statistically significant in partial terms, although there is a tendency for an increase in self-efficacy among students participating in the experimental class. These findings suggest that the discovery learning model with the aptitude treatment interaction strategy is effective in improving students' understanding of mathematical concepts in trigonometry material and has the potential to support the development of self-efficacy in mathematics learning.

Abstract

Penelitian ini merupakan kajian literatur dengan pendekatan Systematic Literature Review yang bertujuan untuk mengevaluasi implementasi pembelajaran berdiferensiasi dalam Kurikulum Merdeka di sekolah. Objek kajian meliputi artikel, jurnal, dan prosiding yang telah diterbitkan sebelumnya. Hasil kajian menunjukkan bahwa pembelajaran berdiferensiasi memberikan dampak positif terhadap peningkatan keterampilan berpikir kritis, pemahaman siswa, partisipasi aktif dalam pembelajaran, dan motivasi belajar. Penerapannya mendorong terciptanya lingkungan belajar yang lebih inklusif dan adaptif terhadap kebutuhan individu. Namun demikian, pelaksanaan di lapangan masih menghadapi berbagai kendala, seperti keterbatasan kompetensi guru, minimnya pelatihan, kurangnya dukungan sumber daya, serta belum optimalnya manajemen pelaksanaan di sekolah. Untuk mengoptimalkan pembelajaran berdiferensiasi, diperlukan pelatihan berkelanjutan bagi guru, evaluasi rutin terhadap praktik pembelajaran, serta peningkatan keterlibatan guru dalam Program Profesi Guru (PPG). Selain itu, pemanfaatan platform digital seperti Merdeka Mengajar dan penguatan koordinasi antara kepala sekolah, guru, dan siswa juga menjadi faktor pendukung keberhasilan implementasi. Kajian ini memberikan gambaran menyeluruh mengenai keberhasilan dan tantangan dalam pelaksanaan pembelajaran berdiferensiasi, serta menawarkan rekomendasi untuk pengembangan program yang lebih efektif di masa mendatang.
