The Influence of E-Learning Platform Usage, Digital Literacy, and AI (ChatGPT) Usage Intensity on High School Students' Mathematics Achievement

Abstract

This study aimed to analyze the influence of e-learning platform usage, digital literacy, and AI (ChatGPT) usage intensity on high school students' mathematics achievement. The method employed was quantitative research with an ex post facto design. The sample consisted of eleventh-grade students from three public senior high schools in Bandung, selected using proportionate stratified random sampling. The research instruments included an e-learning platform usage questionnaire, a digital literacy test, a ChatGPT usage intensity questionnaire, and a mathematics achievement test, all of which met adequate validity and reliability criteria. Data were analyzed using descriptive statistics and multiple linear regression. The results showed that, partially, e-learning platform usage had a positive and significant effect on mathematics achievement. Digital literacy also had a positive and significant effect, contributing the most among the three variables. ChatGPT usage intensity likewise had a positive and significant effect on mathematics achievement. Simultaneously, the three independent variables significantly influenced mathematics achievement, with a strong level of contribution. These findings indicated that optimizing e-learning platforms, strengthening digital literacy, and utilizing AI in a targeted manner were key strategies for improving students' mathematics achievement in the digital era.
