An AI tutor in Sierra Leone reportedly helped students gain a year of schooling in eight weeks, a claim even Google DeepMind cautions us to take with a grain of salt.

In this episode:

• Google DeepMind's AI tutor education trial in Sierra Leone estimated students gained a year's learning in eight weeks, using a re-engineered Gemini model.
• The AI learning tool, Guided Learning, was designed not to give direct answers, fostering productive struggle crucial for learning outcomes.
• Early findings suggest AI in classrooms might initially widen the gap for already proficient students, prompting Google DeepMind to investigate different pedagogies to support struggling learners.
• Teachers in the Sierra Leone trial adapted quickly to AI learning tools, discovering new teaching strategies and increasing one-on-one student interaction after just one day of training.
• Transparent research practices from Google DeepMind, including a public playbook and training materials, aim to allow wider adoption and scrutiny of AI for learning outcomes.

How did Google DeepMind's AI tutor impact learning in Sierra Leone?
The AI tutor education trial in Sierra Leone estimated students gained approximately one year of schooling in just eight weeks, though this figure comes with a scientific caveat from the researchers.

Can teachers trust AI learning tools not to give students answers directly?
The Guided Learning tool, designed by Google DeepMind for AI in classrooms, was specifically engineered not to give direct answers, forcing students into productive struggle, unlike many public AI models.

Do AI learning tools widen the learning gap, or help all students?
Initial findings from the Sierra Leone trial showed that stronger math students benefited most, but Google DeepMind is actively researching different pedagogical approaches for AI to ensure it helps raise the floor for struggling students too.
