Dr. Aardsma's Spelling Drill automatically tailors each drill to the unique needs of the individual student - spending more time on his or her weak areas. It reinforces quick recall by setting speed expectations based on each student's own past performance. Dr. Aardsma's Spelling Drill also teaches vocabulary - each word is given in context in a meaningful sentence. * Gives drills in a real, human voice not a computer-generated robot voice. * Drills nearly 8,000 spelling words in grades 1 through 6 * Accepts any number of students * Prints a progress report at the end of each drill showing the student name, date, time, score for that day (as a percent out of 100), a list of today's words, and a list of words the student may want to practice for tomorrow's drill.
