Adaptive Grammar Instruction

摘要

A grammar teaching system maintains and updates a mastery estimate for a grammar skill and displays an updated visual indication of this estimation. Based on user answers to grammar problems, the system updates the mastery estimate for the grammar skill. Also, a step of a grammar problem is associated with an ordered list of hints. When the user requests a hint for the problem step, the system identifies a position in the list of hints based on how many times the user has previously requested hints for the step. The system displays text that is from the hint at the identified position in the list. Further, a hint for a grammar problem step includes pointer information that refers to a portion of a sentence for the grammar problem. When the system displays the hint, the system highlights the portion of the sentence that is referred to in the pointer information.

1. A computer-executed method comprising:
maintaining, at a grammar teaching system, a mastery estimate of how well a user has mastered a particular grammar skill; the grammar teaching system causing a computing device to display a visual indication of the mastery estimate for the particular grammar skill; the grammar teaching system causing a graphical user interface that depicts a particular natural language sentence to be displayed by the computing device; wherein the particular natural language sentence includes a grammar error, correction of which demonstrates the particular grammar skill; receiving input information comprising a response, from the user, that indicates one or more of:
identification of the grammar error, orcorrection of the grammar error; the grammar teaching system automatically categorizing the response as either correct or incorrect; based, at least in part, on the categorization of the response, the grammar teaching system updating the mastery estimate for the particular grammar skill; and the grammar teaching system causing the computing device to update the visual indication of the mastery estimate for the particular grammar skill to reflect the updated estimation.
