Abstract

Literasi berasal dari kata literacy yang bearti melek huruf/gerakan pemberantasan buta huruf (Echols&Shadily, 1990). Menurut kamus online Merriam-Webster, Literasi berasal dari istilah latin ‘literature’ dan bahasa inggris ‘letter’. Literasi merupakan kualitas atau kemampuan melek huruf/aksara yang di dalamnya meliputi kemampuan membaca dan menulis. Education Development Center (EDC) menyatakan bahwa Literasi lebih dari sekedar kemampuan baca tulis. Dengan pemahaman bahwa literasi mencakup kemampuan membaca kata dan membaca dunia. Untuk meningkatkan kemampuan baca tulis serta mengembangkan segenap potensi yang dimiliki oleh masyarakat Desa Sirnagalih, kami menggunakan berbagai media untuk menarik perhatian masyarakat agar tertarik atau berminat untuk mengembangkan kemampuannya. Melalui media masyarakat akan dengan mudah menerima dan menerapkan apa yang telah mereka ketahui. UNESCO menjelaskan bahwa kemampuan literasi merupakan hak setiap orang dan merupakan dasar untuk belajar sepanjang hayat. Kemampuan literasi dapat memberdayakan dan meningkatkan kualitas individu, keluarga, masyarakat. Karena sifatnya yang “multiple Effect” atau dapat memberikan efek untuk ranah yang sangat luas, kemampuan literasi membantu memberantas kemiskinan, mengurangi angka kematian anak, pertumbuhan penduduk, dan menjamin pembangunan berkelanjutan, dan terwujudnya perdamaian. Buta huruf, bagaimanapun, adalah hambatan untuk kualitas hidup yang lebih baik.

Abstract

Noise yang muncul pada saat perekaman data gerakan mata dapat menyebabkan ketidaktepatan dalam pembacaan data. Berbagai filter pemrosesan sinyal dapat digunakan untuk menghilangkan noise ini, khususnya. Namun, selama pergerakan mata pengejaran yang mulus, perbandingan kinerja filter pemrosesan sinyal tersebut belum diketahui saat diimplementasikan dalam kalibrasi berbasis pengejaran yang mulus. Metode, dalam penelitian ini kami membandingkan tiga filter pemroses sinyal yaitu moving average gaussian dan filter kalman untuk menghilangkan noise pada pergerakan mata pengejaran yang halus. Dalam percobaan, kami membandingkan kinerja filter rata-rata bergerak, gaussian dan kalman. Dari hasil percobaan filter moving average menghasilkan error sebesar 36,97 +_ 10,62 [1]piksel. (posisi horizontal) dan 48,07 +_ 15.11[2] pixel ( posisi vertikal ) filter gaussian menghasilkan error sebesar 37.74 +_ 11.23 [3] pixel ( posisi horizontal dan 51.06 +_ 17.62 pixel ( posisi vertikal ), filter kalman menghasilkan error sebesar 56.06 +_ 30.97[4] pixel ( posisi horizontal) dan 72.98 +_ 41,21[5] piksel ( posisi vertikal. Hasil eksperimen menunjukkan bahwa filter moving average menghasilkan akurasi terbaik dibandingkan dengan filter pemrosesan sinyal lainnya. Di masa depan, hasil kami mungkin digunakan dalam pengembangan prosedur kalibrasi yang tidak mengganggu untuk interaksi berbasis tatapan spontan.

Abstract

The use of authentic contexts in numeracy learning is important to help prospective elementary school teachers design meaningful and contextual mathematics instruction. However, a gap remains in the literature regarding how prospective teachers perceive the feasibility and potential of authentic context-based numeracy activities. This study aimed to explore how elementary student teachers in a Teacher Professional Education (TPE) program perceive the feasibility and potential of implementing the activity "Analysis of Composition Labels of Snack Foods" as a vehicle for promoting numeracy learning. A descriptive qualitative method was employed, involving 57 TPE students who completed a perception questionnaire following the learning activity. Data triangulation was conducted through semi-structured interviews and classroom observations. Quantitative data were analyzed using descriptive statistics, while open-ended responses were analyzed through content analysis using NVivo 12. Findings revealed that 92.98% of participants regarded the activity as feasible and relevant for initial numeracy assessment, recognizing its contextual nature, engaging quality, and ease of implementation. The activity was found to support the development of cognitive and practical skills, including proportional reasoning, unit conversion, critical thinking, and data interpretation. Furthermore, the activity demonstrated applicability across multiple elementary school subjects, reflecting its potential as a cross-curricular instructional approach. These findings suggest that snack food composition label analysis is a feasible and beneficial learning activity that can be meaningfully integrated into core elementary mathematics topics, including fractions, measurement, and data presentation.

Abstract

This paper explores the transformative role of character-based digital citizenship in redefining civic education in the digital era. Amid the rapid flow of information and the growing negative impact of technology on national values, civic education must be adaptive and relevant. The study highlights the strategic contribution of digital citizenship to achieving the Sustainable Development Goals, in particular Target 4.7, which emphasises education for sustainable development and global citizenship, and Target 16, which supports peaceful and inclusive societies and access to justice. This research applies a descriptive qualitative approach, using a systematic literature review strategy combined with thematic analysis, to critically and in-depth explore relevant scientific literature. These findings suggest that integrating character education into digital citizenship fosters ethical awareness, responsible digital behaviour, and democratic participation. This synergy strengthens civic competence and promotes inclusive, peaceful, and sustainable educational settings. The study provides strategic insights for educators, curriculum developers, and policymakers, proposing new conceptual models that align digital citizenship with global citizenship goals and advance 21st-century citizenship learning.

Abstract

Textbooks exert minimal influence on learning outcomes, underscoring the urgent need to develop high-quality, context-responsive teaching materials for prospective educators. This study designed, validated, and evaluated Realistic Mathematics Education (RME)-based instructional materials using the ADDIE (Analysis, Design, Development, Implementation, Evaluation) framework. Participants included 60 prospective teachers from Pasundan University, randomly assigned to experimental (RME-based materials) and control (conventional textbook) groups. Data were collected through observations, questionnaires, and achievement tests, with ANOVA used for analysis. Expert validation scores were high: material experts (91.86%), learning model experts (92.58%), and peers (92.40%), confirming strong validity. Practicality was similarly high, with small-group and large-group student assessments scoring 92.40% and 92.03%, respectively. Post-intervention, the experimental group outperformed the control group significantly (mean scores: 91.8 vs. 69.5; Δ = 22.3), supported by robust statistical evidence: F(1,47) = 45.07, p < 0.001, η² = 0.49, Cohen’s d = 1.39—indicating a large effect size. Findings confirm the RME-based materials are valid, practical, and highly effective in improving prospective teachers’ learning outcomes. Broader implementation and adaptation to other mathematics topics are strongly recommended.

Abstract

This study aims to determine the effect of the Game Based Learning model assisted by the Kahoot application on the learning outcomes of elementary school students in science. The study used a quantitative approach with a quasi-experimental design, involving two groups, namely the experimental class and the control class. The research sample was fifth-grade elementary school students selected using a specific sampling technique. Data collection was carried out through pretests and posttests. Data analysis used the Independent Sample T-test to see differences in learning outcomes between groups, as well as the effect size test to determine the magnitude of the treatment effect. The results showed that the average posttest score of the experimental class was higher than the control class. The Independent Sample T-test produced a significance value of 0.001 (<0.05) with an effect size value of 1.229 which is included in the large category. These findings indicate that the Game Based Learning model assisted by the Kahoot application has a significant and strong influence on the learning outcomes of elementary school students in science.
