🤖 AI Summary
This study investigates the differential cognitive functions and educational value of large language models (LLMs; e.g., ChatGPT) versus search engines (e.g., Google) in students’ self-directed learning of novel topics. Employing a within-subjects balanced experimental design, complemented by semi-structured interviews and thematic analysis, it systematically compares student-centered usage preferences, epistemic decision-making processes, and learning tensions arising during information discovery, synthesis, and verification. The study identifies, for the first time, a dynamic trade-off between “cognitive effort reduction” and “epistemic agency”—the learner’s capacity to critically evaluate, justify, and regulate knowledge claims. Six prototypical learning tension scenarios are empirically derived. Building on these findings, the research proposes a contextualized technology adoption framework that informs evidence-based design of educational technologies, pedagogical integration of LLMs, and cultivation of critical digital literacy.
📝 Abstract
Large language models (LLMs) are transforming how students learn by providing readily available tools that can quickly augment or complete various learning activities with non-trivial performance. Similar paradigm shifts have occurred in the past with the introduction of search engines and Wikipedia, which replaced or supplemented traditional information sources such as libraries and books. This study investigates the potential for LLMs to represent the next shift in learning, focusing on their role in information discovery and synthesis compared to existing technologies, such as search engines. Using a within-subjects, counterbalanced design, participants learned new topics using a search engine (Google) and an LLM (ChatGPT). Post-task follow-up interviews explored students' reflections, preferences, pain points, and overall perceptions. We present analysis of their responses that show nuanced insights into when, why, and how students prefer LLMs over search engines, offering implications for educators, policymakers, and technology developers navigating the evolving educational landscape.
