The 8 Great Diagnostic is a Comprehensive, free educational application to determine what level to start individualized lessons using the 8 Great Word Patterns apps. Each level is downloaded separately. In this diagnostic a student will be asked to spell (type) words of increasingly harder word patterns. The student will progress through the levels as they get a score of 80%. When the diagnostic is done, a score will appear revealing which level to start on. The level has more relevance to the pattern complexity than to a grade level.

These apps were developed by Dr. Gary Moser, a fourth grade teacher who has a doctorate in Reading and over 20 years experience tutoring struggling readers. Informal research has proven four times the growth expected for Special Education students in 3-6th grade. Current research is being conducted in school year 2013-2014. Findings will then be shared.

The absolute biggest issue with this is the ability for words to be autocorrected. Every time I entered a word, the little menu was there for highlight, copy, etc. I know that would not work for my students.

Also, at what point does it stop? I intentionally entered misspellings over and over. It keeps going.

Not sure I would find this useful.

Great job

This is great for little kids who need to learn spelling and reading.

Doesn't work

I would think the reason it doesn't work is so parents will buy all levels. Bad business!
