9. A method for assessing a student's reading ability, the method comprising: associating a first mark and a first notation on a worksheet comprising a position-identifying pattern with a first word by: detecting, by a digital pen capable of both writing on a substrate and capturing data corresponding to a user's handwriting, a first mark in a first region of the worksheet, wherein the first mark is in a first indicator portion of the position-identifying pattern contained within a first indicator region that is associated with a first word, wherein the digital pen comprises an image-capturing sensor, after detecting the first mark, detecting, by the image-capturing sensor, a first note portion of the position-identifying pattern corresponding to a first notation in a note region of the worksheet, and associating all subsequently detected portions of the position-identifying pattern in the first region and the note region of the worksheet and the corresponding marks and notes with the first word until another indicator portion of the position-identifying pattern that corresponds with another word is detected; based on whether the first mark, the first notation, or both indicates that the first word was read incorrectly or correctly, determining a first reading assessment result for the first word; and storing, in a memory, a digital document file comprising the first reading assessment result, the marks and notations associated with the first word, and information identifying where on the worksheet the markings and notations associated with the first word are located.

The method according to claim 9 , further comprising: on a condition the first indicator portion corresponds to the incorrect region for the first word, categorize an error for the first word as one of an uncorrected error, a self-corrected error, or a re-read based on the first mark.
