WHY YOU NEED A CUSTOM CONTEXT PROVIDER

"Naked" React Context providers can be bad for performance due to unnecessary re-renders.

ANTHROPIC EDUCATION REPORT: HOW UNIVERSITY STUDENTS USE CLAUDE

Anthropic's Education Report analyzes one million anonymized student conversations with Claude.ai to understand AI usage in higher education. The study found that STEM students, especially those in Computer Science, are early adopters who use AI for tasks like problem-solving and output creation. Students mostly use AI for higher-order cognitive functions like creating and analyzing, which means there are concerns in creating a dependence and over-reliance on AI.
