ChatGPT and Learning: A Double-Edged Sword
The use of ChatGPT in the educational field is on the rise, promising quick revisions and instant explanations. However, a recent study highlights a major issue: the negative impact on students' long-term memory.
The study, led by André Barcaui, shows that the use of AI for learning could weaken knowledge retention abilities. While the tool facilitates access to information, it also seems to encourage a dependency that harms memorization.
Cognitive Load: A Barrier to Memorization
The results of the study are clear: students who rely on ChatGPT retain less information after 45 days compared to those who study without the help of AI. The difference is significant, with an 11% decrease in retention scores.
This phenomenon is attributed to what researchers call cognitive load. In other words, the brain becomes accustomed to delegating the task of memorization to the tool, remembering more about the location of the information than the information itself. This process is similar to the effect observed with Google, but even more pronounced.
The Illusion of Competence: A Trap for Students
Another concerning aspect is the illusion of competence. With ChatGPT, students feel they have mastered a subject without truly assimilating the concepts. This borrowed competence does not rest on a genuine consolidation of knowledge.
Moreover, the study reveals that students using AI spend almost twice as little time studying. This reduction in learning time translates to less cognitive effort, which is essential for strengthening memory. Even regular users of ChatGPT do not perform better in terms of memorization, and the habit of using this tool does not protect against memory loss.
Towards a More Thoughtful Use of AI
Despite these findings, researchers do not advocate for abandoning ChatGPT. Instead, they encourage a thoughtful use of the tool. It is advised to use it to verify answers or to complement learning, rather than relying on it blindly.
Memory, compared to a muscle, requires regular exercise to develop. Cognitive effort remains essential for effective and lasting learning.
