Abstract

The rapid integration of digital technologies in educational environments has sparked critical debates on the ethical implications of such changes. While digital transformation offers unprecedented opportunities, it simultaneously raises concerns about privacy, equity, algorithmic bias, and the dehumanization of learning. This opinion article, grounded in current literature, explores the urgency of addressing digital ethics in education. It presents a conceptual framework that links ethical principles to digital educational practices and analyzes pressing ethical challenges. Through a structured discussion supported by data and literature, the paper highlights the necessity for a proactive and inclusive dialogue among stakeholders to ensure a morally responsible future for education.

Abstract

This study examines the influence of the Realistic Mathematics Education (RME) approach on eighth-grade students’ ability to solve plane geometry problems at Ensino Básico 3° Ciclo São José Operário Balide during the 2025 academic year. The research followed a quantitative pre-experimental design using a one-group pre-test and post-test structure. Prior to data collection, a try-out test consisting of 15 items was administered to 10 non-sample students to determine the validity and reliability of the research instrument. The results indicated that 10 items met the validity criteria, while 5 items were invalid. All 10 valid items demonstrated acceptable reliability, allowing their use as the main instrument for measuring students’ problem-solving ability. After administering the pre-test and post-test to the sample class, normality testing using the Lilliefors method showed that both pre-test (Lmax = 0.3707 > Ltabel = 0.14) and post-test data (Lmax = 0.4562 > Ltabel = 0.14) were normally distributed. Linearity testing further revealed that Fcount < Ftable (−28.18 < 2.78), indicating a linear relationship between the two sets of scores. Given the conditions of normality and linearity, the paired-sample t-test was conducted to determine the effect of the RME approach. The results showed a significant difference between the pre-test and post-test mean scores, demonstrating that RME positively influenced students’ geometry problem-solving abilities. These findings support the view that RME, grounded in constructivist principles, effectively encourages active student participation and enhances conceptual understanding in mathematics learning.

Abstract

Background: The ability to distinguish between fact and opinion is a critical component of academic literacy and scientific reasoning, particularly in the digital age where students encounter complex information flows. However, misconceptions and reliance on intuition are common among higher education students, undermining critical evaluation of scientific claims. Purpose: This study aims to analyze the abilities of English Literature students at Halu Oleo University in classifying facts and opinions, and to identify factors influencing this process. Method: A mixed-methods design was employed, involving a questionnaire completed by 82 students and an argumentative analysis of their written responses based on Toulmin’s model. Quantitative data were analyzed using descriptive statistics, while qualitative data were thematically coded to assess claim construction, warrant application, use of evidence, and consideration of rebuttals. Results: The results of the study show that students tend to rely on intuition, everyday empirical experience, and common sense. sense compared to critical evaluation based on scientific evidence in determining facts and opinions. Furthermore, students’ abilities in constructing claims, providing warrants, using scientific evidence, and considering rebuttals are still relatively low. This study also found that low levels of critical digital literacy affect students’ ability to verify information and recognize digital information bias. Conclusion: These findings highlight the urgent need to strengthen epistemological literacy, argumentative skills, and digital critical literacy in academic curricula to improve students’ scientific reasoning and information evaluation capabilities.
