Abstract

Educational game media developed based on problem-based learning is one alternative designed to help students improve their mathematical literacy skills and understand sequences and series in a more interesting and interactive way. This study aims to examine the validity, practicality, and effectiveness of using media in mathematics learning. The type of research used is development research with the ADDIE research model. This study was conducted at MAN 1 Medan with class X-16 as the subject. The results showed that the use of educational game learning media could improve the mathematical literacy skills of class X-16 students. This was indicated by the results of subject matter expert validation with a percentage of 88% in the ‘highly valid’ category, as well as media expert validation results with a percentage of 89.9% in the ‘highly valid’ category. In addition, the students' response to the media reached 88.4% and was categorised as ‘very practical’, which was also supported by the N-Gain results on the mathematical literacy skills of class X-16 students with a result of 0.710, which falls into the high category, meaning that the educational game media developed is effective for use in learning the material on sequences and series

Abstract

This study aims to determine the effectiveness of the Problem-Based Learning (PBL) model in improving senior high school students’ critical thinking skills on the topic of function transformations. This research employed a quasi-experimental design with one experimental class taught using the PBL model. The subjects of the study were 30 students. The research instrument was a critical thinking test covering the following indicators: analyzing and formulating problems, providing further explanations, developing strategies and tactics, and drawing conclusions. Data were analyzed using the Shapiro-Wilk normality test, paired sample t-test, N-Gain, and Cohen’s d. The result of the study showed that: (1) the average pretest score of 46,45 increased to 85,07 in the posttest, with a classical mastery level of  75%; (2) the t-test revealed a significant difference (Sig.0,05); (3) the mean N-Gain score was 0,73, categorized as high; and (4) Cohen’s d was 4,63 categorized as a very strong effect.Keywords: Problem-Based Learning, critical thinking skills, N-Gain, Cohen’s d, t-test

Abstract

Purpose - This study critically synthesizes research on the development of technology-based assessment instruments in secondary science education (junior and senior high school) through a structured Narrative Literature Review (NLR). This review therefore identifies instrument types, implementation contexts, research dimensions examined, and learning impacts, while highlighting gaps in equity, teacher readiness, and longitudinal outcomes.Methodology - Articles were systematically retrieved from Google Scholar and Mendeley within the 2015–2025 publication range using predefined keywords related to technology-based assessment and science learning. Inclusion criteria required peer-reviewed empirical studies focusing on secondary-level science and reporting instrument development or evaluation. Fourteen eligible articles were analyzed using structured content analysis, with emphasis on instrument characteristics, evidence of validity and reliability, implementation contexts, methodological approaches, and reported limitations.Findings - The synthesis indicates that research predominantly centers on Computer-Based Testing (CBT), Computerized Adaptive Testing (CAT), gamified assessments, two-tier diagnostic tests, and LMS-based e-portfolios. Overall, these instruments demonstrate satisfactory validity and reliability and effectively measure higher-order thinking skills and conceptual understanding. They also enhance student motivation and accelerate feedback processes. However, most evidence is based on short-term, small-scale implementations, with limited attention to equity issues, teacher readiness, and sustained learning effects.Contribution - This review integrates psychometric, pedagogical, and technological perspectives into a coherent analytical framework for technology-based assessment in science education. It clarifies existing research gaps and underscores the need for broader contextual validation, stronger methodological rigor, and the integration of learning analytics to ensure sustainable and evidence-based digital assessment practices.

Abstract

The purpose of this study was to determine the quality of daily test items in mathematics subjects on SPLDV material for class IX in the 2024/2025 school year. The research method applied in this research is quantitative descriptive method, with samples in the form of 16 student answer sheets and question sheets. Data were collected through interviews conducted with Mathematics subject teachers, to find out the purpose and technique of preparing questions using documentation techniques copies of description question sheets and student answer sheets. Analysis of validity, reliability, difficulty level, and distinguishing power was carried out to determine the quality of the items. The results showed that in the validity analysis, there were 3 questions that were declared valid and one invalid. The results of the reliability analysis, the question was low with a Cronbach's Alpha value of 0,492, indicating weak inter-item consistency. The results of the difficulty level analysis showed that three questions were classified as easy (index 0,71–1,00), and one question was classified as moderate. And the results of the differentiating power analysis, the four description items have good differentiating power.

Abstract

Background: Literacy and numeracy are fundamental competencies in fostering critical thinking skills in early childhood; however, early childhood education teachers in Stabat District, Langkat Regency, face limitations in integrating literacy and numeracy instruction with the values of the Sustainable Development Goals (SDGs). Objective: This community service program aimed to enhance teachers’ competencies in implementing SDGs-based literacy and numeracy learning in a contextual and meaningful manner. Methods: The program employed a Participatory Action Research (PAR) approach over three months, comprising stages of socialization, training, and workshops; implementation of educational technology; mentoring; and evaluation. Data were collected using pre-test and post-test instruments, classroom observations, and teacher reflections, and were analyzed descriptively by comparing pre- and post-intervention conditions. Results: The findings indicate a significant improvement in teachers’ average understanding of literacy (from 56.4 to 82.1), numeracy (from 53.8 to 80.6), and the integration of the SDGs (from 48.2 to 79.3). In addition, one-way instructional practices decreased from 72.5% to 20.0%, while interactive learning increased to 80.0%, and the use of innovative learning media reached 85.0%. Conclusion: The SDGs-based literacy and numeracy approach effectively strengthened teachers’ pedagogical competencies and promoted more interactive, contextual, and sustainable early childhood learning practices.
