Cognitive Growth or Cognitive Laziness? AI Tools in Student Education

AI-powered platforms such as ChatGPT, Gemini, Copilot, and Grammarly have become central fixtures in student academic life. This paper examines whether these tools advance genuine cognitive development or quietly erode it. Drawing on a systematic review of five peer-reviewed studies (2023–2025) and a primary student survey, the paper identifies both documented benefits — improved task efficiency, wider accessibility, and reduced entry barriers — and serious risks, including declining neural engagement, weakening critical thinking, lower autonomous decision quality, surface-level knowledge formation, and deteriorating metacognitive awareness. The cumulative effect of habitual AI use is framed through the concept of ‘cognitive debt.’ Five novel technical frameworks are proposed to redesign AI-student interaction so that cognitive effort is demanded rather than bypassed.
