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

The assessment of students' critical thinking abilities is crucial for the learning process; however, numerous educators have been unable to select high-quality evaluation tools. A question that is effective must satisfy the following criteria: adequate validity, reliability, difficulty level, differentiating power, and effectiveness of the checker. A quantitative approach was employed in this study, which employed descriptive methods in one of the high schools in Yogyakarta. 15 summative test items on derivative material were administered to 30 students as the research subjects. The question is declared valid, as the content validity results using V-Aiken's indicate a value of 0.8889. This value is classified as high. The reliability test yielded a value of 0.924 for choice questions and 0.777 for description questions, suggesting that the questions were reliable. The analysis of the items revealed that item number 6 required deletion due to its low differential power, while item number 7 required revision. Questions 10 and 12 should be addressed in accordance with the level of difficulty. The exemptions are ineffective, necessitating revision of the answer options in question numbers 9 and 10. This research underscores the significance of enhancing evaluation instruments to facilitate the attainment of student learning indicators.

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

The diversity of students’ learning profiles and the limited use of data-driven diagnostic assessment in mathematics classrooms present significant challenges in implementing differentiated instruction. Current classroom practices are still insufficiently supported by digital systems capable of accurately identifying students’ learning needs in real time. This study aims to develop SIDIC (Student Identification for Diagnostic Instructional Classification), a learning analytics–based digital diagnostic assessment system designed to identify junior high school students’ mathematics learning profiles and support data-driven differentiated instruction. The study employed a research and development approach using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. Instrument validity was evaluated by seven experts across 40 items covering 10 aspects, resulting in an average Aiken’s V of 0.85, indicating high validity. Practicality testing involved 92 students and 9 mathematics teachers from three schools, showing that SIDIC falls into the very practical category (student score = 4.33; teacher score = 4.49). The findings indicate that SIDIC is easy to use, efficient, and effective in identifying students’ learning profiles. Overall, SIDIC represents a valid, practical, and adaptive digital assessment innovation that bridges diagnostic assessment, digital technology, and data-driven differentiated instruction within an integrated system.

Abstract

This study aims to analyze the effectiveness of implementing the Problem-Based Learning (PBL) model with a contextual approach in improving students’ mathematical creative thinking skills. This research employed a pre-experimental design using a one-group pretest–posttest approach involving 30 eighth-grade students in Yogyakarta, selected through purposive sampling techniques. The research instruments consisted of a creative thinking skills test and observation sheets. The results showed a significant difference between students’ pretest and posttest scores based on the paired-sample t-test (p-value = 0.0001 0.05). Furthermore, the one-sample t-test results indicated that the average creative thinking ability of students had reached the predetermined mastery criteria (p-value = 0.0001 0.05). The proportion test also demonstrated that classical learning mastery was achieved (p-value = 0.010 0.05), with at least 75% of students reaching the mastery criteria. Thus, it can be concluded that the integration of the PBL model with a contextual approach is effective in enhancing students’ mathematical creative thinking skills and supports active engagement in learning

Abstract

Blended learning has been widely implemented in education, particularly in response to the rapid development of digital learning environments. However, existing studies predominantly focus on implementation practices and general learning outcomes, while neglecting the cognitive mechanisms that underlie learning effectiveness. This study addresses this gap by analyzing research trends, conceptual structures, and existing research gaps in blended learning through the integration of Cognitive Load Theory and retrieval practice. The objective of this study is to map the development of blended learning research and identify the extent to which cognitive principles have been incorporated into instructional design studies. A bibliometric approach was employed using data retrieved from Scopus and Google Scholar databases covering the period 2020–2025. The data were analyzed using VOSviewer to examine keyword co-occurrence networks, thematic clusters, temporal trends, and research density. The results indicate that blended learning research remains fragmented and largely focused on implementation issues, student engagement, and pandemic-related educational contexts. Although there is a growing interest in theoretical perspectives, the integration of Cognitive Load Theory and retrieval-based learning strategies remains limited. Furthermore, cognitive constructs such as prior knowledge activation, working memory management, and retrieval processes are underrepresented in high-density research clusters, indicating a significant research gap in cognitively grounded instructional design. This study highlights the need for a more structured instructional framework that integrates cognitive principles, particularly through pre-learning interventions that enhance retrieval practice and optimize cognitive load management. The findings contribute to the development of a more theory-driven blended learning model aligned with human cognitive architecture.

Abstract

The importance of integrating Information and Communication Technology (ICT) into mathematics learning lies in its potential to enhance students’ critical thinking, problem-solving, and logical reasoning skills. Conventional assessments often face limitations in providing personalized and dynamic feedback. This study aims to examine the effectiveness, challenges, and pedagogical impacts of ICT-based mathematics assessment through a systematic review of literature published between 2020 and 2025. The research method employed is a Systematic Literature Review (SLR) following the PRISMA guidelines. Data were collected from the Scopus, WoS, ERIC, and Google Scholar databases using relevant keywords. The selection process involved identification, screening, eligibility assessment, and inclusion, resulting in n=15 articles for comprehensive analysis. The findings indicate that ICT-based assessment is effective in measuring cognitive domains, particularly conceptual understanding (33.3%), problem solving (26.7%), and learning outcomes (26.7%), while other aspects remain limited mathematical reasoning and self-assessment (13.3%). Furthermore, challenges in implementing ICT-based mathematics assessment include the design and development of instruments, technical and infrastructural limitations, teachers’ readiness and competencies, as well as student characteristics and the context of online learning. ICT-based assessment in mathematics also provides five main pedagogical impacts: enhancing student engagement and motivation, offering feedback and self-reflection, fostering cognitive and problem-solving skills, improving learning efficiency, and promoting pedagogical innovation.
