 **Educational cloze testing (1953)**: Wilson L. Taylor introduced the cloze procedure—systematically deleting words from passages to measure reading comprehension. It became standard in U.S. educational assessment by the 1960s.
 
-**Masked language modeling (2018)**: BERT and subsequent models rediscovered cloze methodology independently as a training objective, randomly masking tokens and predicting from context. Both domains converge on the same principle: understanding language means predicting from context.

 **This project**: Uses language models trained on prediction tasks to generate prediction exercises for human readers. While Gemma-3 uses next-token prediction rather than masked language modeling, the system demonstrates how assessment and training methodologies are now instrumentalized through identical computational systems.
