Personalized AI Benchmarks Comparison For ESL
+ New Speaking Activity and Future of Work Lesson
Summary: AI Benchmarks for ESL Lesson Creation
I compared Claude, ChatGPT, and Gemini across 22 metrics while creating multi-exercise lesson packages on various contemporary topics. Each package includes 10-12 exercises: brainstorming, visual vocabulary, listening quizzes, gap-fills, collocations, grammar, critical thinking, and role plays.
Disclosure: I use Claude most frequently and prefer its workflow, so there’s inherent bias. These are personal impressions, not scientific results. Download the PDF for the full list of metrics and scores.
Final Scores (out of 220):
Claude: 174
Gemini: 162
ChatGPT: 141
Key Takeaways:
Claude excels at workflow — zip packaging, multiple formats from one prompt, task chaining, format fidelity. Strong on innovation, proactively suggesting improvements. Weakness: no native image generation.
Gemini leads on image generation and infographics (speed and quality). Good step-by-step monitoring. Major weakness: no zip downloads.
ChatGPT produces nice minimalistic infographics but struggles with reliability — dropped files, inconsistent outputs, weaker task chaining.
Universal issues: All three need checking for answer key accuracy, randomization patterns, and vocabulary drift. Autonomous planning without prompting produces repetitive content. Human oversight essential.
