Query: Natural Deduction and the Isabelle Proof Assistant   We describe our Natural Deduction Assistant (NaDeA) and the interfaces
between the Isabelle proof assistant and NaDeA. In particular, we explain how
NaDeA, using a generated prover that has been verified in Isabelle, provides
feedback to the student, and also how NaDeA, for each formula proved by the
student, provides a generated theorem that can be verified in Isabelle.
