ADAPTIVE GRAMMAR INSTRUCTION FOR PRONOUNS

Techniques are described for an automated grammar teaching system that displays sentences and allows a user to identify pronoun errors or noun phrases that should be replaced with pronouns within the sentences, if any. The user may be asked to complete one or more of the following: to determine whether the sentences have a pronoun error or a noun phrase that should be replaced by a pronoun, to identify the type of the pronoun error, to identify the antecedent or core nouns that determine a plurality of the antecedent, to select a replacement sentence to best correct the pronoun error, and/or to locate an incorrectly displayed pronoun or a noun phrase and type a replacement pronoun. To guide the user, user responses may trigger the display of remediation information, which may include reasons why the user response is incorrect.
