20. The system of claim 1 wherein the position-identifying pattern covers the entire worksheet.
1. A student reading performance assessment system, comprising: a worksheet having a position-identifying pattern configured to be read by an image-capturing device printed thereon, the worksheet comprising: a plurality of indicator regions, each comprising at least one indicator portion of the position-identifying pattern; a plurality of words each associated with at least one of the indicator regions; and a note region, comprising a note portion of the position-identifying pattern; and a digital pen capable of both writing on a substrate and capturing data corresponding to a user's handwriting, the digital pen comprising an image-capturing sensor, a processor, and a tangible, computer-readable memory with instructions that, when executed, cause the processor to: associate a first mark and a first notation on a worksheet comprising a position-identifying pattern with a first word by: detecting, by the image-capturing sensor, a first indicator portion of the position-identifying pattern corresponding to a first mark in a first one of the indicator regions that is associated with a first word, after detecting the first indicator portion, detecting, by the image-capturing device, a first note portion of the position-identifying pattern corresponding to a first notation in the note region, and after the first indicator portion of the position-identifying pattern is detected by the image-capturing sensor, associating all subsequently detected portions of the position-identifying pattern in the first indicator region and the note region of the worksheet and the corresponding marks and notations with the first word until another indicator portion of the position-identifying pattern that corresponds to another word is detected by the image-capturing sensor; based on whether the first mark indicates that the first word was read incorrectly or correctly, determine a first reading assessment result for the first word, and store, 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.
