Three research ideas. Five classroom investigations. Read the evidence, make a prediction, then test it with a model.
Teacher setup, model choices and notebook guide →Pip and the library that guessed
How can we help a model check, correct and learn from made-up answers?
Open investigation →When time becomes a calculation
Does a calendar-shaped representation mean a model calculates directly on a calendar?
Open investigation →A story leaves a trail
How does a model’s picture of a story change as it reads another sentence?
Open investigation →Stories through representation space
How much of a story trajectory comes from context, model, readout or projection?
Open investigation →Based on three Goodfire research papers. Original demonstrations are attributed and embedded from Goodfire. Spark’s classroom activities are independent adaptations, with their limits stated beside the results.
