Abstract

This study examines Differential Item Functioning (DIF) in an instrument developed to measure preservice mathematics teachers’ ethnomathematical knowledge in Jambi. Anchored in the Rasch measurement framework, this study employs a quantitative ex post facto design to evaluate item‑level measurement invariance of an ethnomathematics assessment instrument. Rasch‑based procedures: item and person parameter estimation, fit statistics, and DIF analyses were employed to assess item equivalence across gender, educational background, and teaching experience, and to quantify the magnitude of any detected DIF. Data from 150 preservice teachers were analyzed using Rasch estimation and Mantel–Haenszel DIF on a culturally contextualized ethnomathematics instrument. Descriptive analyses indicated strong psychometric properties of the instrument, with person reliability = 0.81, item reliability = 0.97, and fit statistics falling within acceptable ranges. DIF analyses revealed several items with statistically significant DIF predominantly across gender, while the majority of items demonstrated stable functioning across the examined participant subgroups. Graphical DIF plots revealed heterogeneous item‑response patterns in the ethnomathematics instrument, highlighting the need for culturally responsive item revision to reduce bias. Findings demonstrate the Rasch model’s effectiveness in detecting item‑level bias in instruments measuring preservice teachers’ ethnomathematical knowledge and substantiate targeted refinement of measurement instruments.

Abstract

This study aimed to develop and evaluate an ethnomathematics-based test instrument for assessing seventh-grade students’ mathematical process skills in algebraic expressions. The study employed a Research and Development design using the ADDIE model, which consists of Analysis, Design, Development, Implementation, and Evaluation stages. The research was conducted at SMP Negeri 9 Kota Jambi, Indonesia, involving one mathematics teacher, nine students in the small-group trial, and twenty-six students in the field trial. The developed instrument consisted of ten essay items integrating algebraic expressions with Jambi ethnomathematical contexts and measuring five indicators of mathematical process skills: observing, classifying, identifying relationships, calculating, and communicating results. Data were collected through expert validation sheets, practicality questionnaires, student response questionnaires, students’ written answers, and documentation. The results showed that the instrument obtained an expert validation score of 88.39%, indicating a very valid category. The practicality score reached 95.45% from the teacher and 81.71% from students, indicating that the instrument was feasible for classroom use. Empirical item validity analysis showed that all ten items were valid, with r-count values exceeding the r-table value of 0.367. Reliability analysis produced a Cronbach’s alpha coefficient of 0.846, indicating high internal consistency. Student response results reached 85.87%, showing positive acceptance of the instrument. Field implementation also revealed that most students still demonstrated low mathematical process skills in contextual algebra tasks. These findings indicate that the developed instrument is valid, practical, reliable, and appropriate for diagnosing students’ mathematical process skills through culturally meaningful algebra assessment.

Abstract

The mathematical problem-solving ability of junior high school students is still low, requiring contextual and innovative learning methods. This study aims to improve the problem-solving skills of eighth-grade students at SMP Negeri 10 Kota Jambi in statistics through Problem Based Learning (PBL) supported by Wegos media and TikTok videos. A quantitative approach with a quasiexperimental Nonrandomized Control Group Pretest-Posttest Design was applied. The sample consisted of an experimental class using PBL with Wegos and TikTok and a control class using conventional methods. Data were obtained from pretests and posttests, analyzed using the Shapiro-Wilk test, Mann-Whitney test, and Effect Size. The results showed a significant difference, with the experimental class achieving moderate improvement and a large effect size. As a result, PBL supported by Wegos and TikTok is effective in improving students’ mathematical problemsolving skills.

Abstract

Ethnomathematics is a potential alternative solution in efforts to preserve culture through the process of cultural integration (ethnography) in mathematics learning. Teachers play an important role in the successful implementation of ethnomathematics. Teachers need to have a deep understanding of the conceptual and practical aspects of ethnomathematics. This knowledge must be known from the start, even when they are still at the stage of becoming prospective mathematics teachers. Therefore, it is important to measure prospective teachers' ethnomathematics knowledge accurately to see the picture of prospective teachers' ethnomathematics knowledge. This research aims to increase the accuracy of measuring the ethnomathematics knowledge of prospective mathematics teachers by comparing several models in the Modern Test Theory approach, which include the Rasch Model, 1, 2, and 3 Parameter Logistics. Data collection was carried out using the Jambi culture-based ethnomathematics test for prospective mathematics teachers with respondents as many as 129 prospective mathematics teachers from Jambi Province. The criteria for the level of accuracy of the model are indicated by the Standard Error Measurement (SEM) and Test Information Function produced by each model. Based on the results of this research, it was concluded that using the Rasch Model produces the best level of accuracy. It is hoped that this research can open new avenues in increasing precision in measuring ethnomathematics knowledge for prospective mathematics teachers.

Abstract

This community service program aimed to enhance teachers’ understanding of the conceptual framework of the Programme for International Student Assessment (PISA) and improve their skills in developing locally contextualized assessment items. The activity responded to teachers’ limited ability to design questions requiring critical thinking and problem-solving, as well as their lack of experience in applying contextual tasks in classrooms. The program involved conceptual framework dissemination, training and mentoring on item development, classroom implementation, and evaluation through pre-tests, post-tests, response sheets, and classroom observations. Twenty-one participants, including teachers from Al-Arief Islamic schools and students from Jambi University, actively engaged in all stages. Results showed an increase in average scores from 2.62 to 4.04, with an N-Gain of 0.60 (moderate). Teachers’ knowledge, experience with assessment tasks, and problem-solving strategies all improved significantly. The novelty lies in integrating local contexts into item design, which strengthened teachers’ conceptual understanding and readiness for classroom implementation. The training proved effective in building teachers’ capacity and supporting more relevant and contextual teaching practices.
