Correct spelling requires a close knowledge of the exact letters which make up a word, so knowing how to spell a word correctly should mean that the word will be very accurately read.
The program provides a mechanism for inputting spelling words, breaking them up into syllables and providing sounds for the words, syllables, phonics or letters. Also there are many spelling exercises for various grades available with the installation of the program, the included CD and the website.
The student part of the spelling module includes a way to see and hear the proper spelling of a word and then to practice the spelling. After taking a test, the student can review the incorrectly spelled words and make corrections and practice again. A teacher or parent can review the test results and see where any spelling weakness may be.
It would be impractical for a teacher to give a different set of spelling words to different students in the same class. However, with the Teaching-Engine, assigning different lessons to different students in a school computer lab is simple. If the program is being used at home, then it is really quite easy.
Analyzing the misspellings also can give further clues. For example, if the student consistently just spells words with a rough phonetic guess, and it never changes with every try, then he is likely not getting anything out of the practice. A student who is trying and does pay attention to the practice will have spelling results that successively come closer to the correct spelling with every practice-test cycle.
Other clues could be reversals such as with saw and was, letters mixed up such as a and o, m,n and w, and the very typical b,d,p and q. These kinds of problems can easily drop a spelling score from 80 to 45 percent.
