A teacher in my school has experimented with the program and had some issues which I hope you can help me sort out.
I used this last year with the Year 1/2 students and encountered quite a few obstacles. I tried it again this year, and have documented some of the problems we have encountered:

Even when the settings are set to the lowest sensitivity, it still doesn’t correctly identify all the errors in the text. For example,
1. Students that are decoding individual words, are marked as an insertion even if they blend these sounds and read the whole word.
2. Repetitions/self-corrections are frequently marked as omission and insertions, which results in an error when it shouldn’t be.

Examples of problems encountered:

Child said, “The Fish” – should be a mispronunciation but instead marked as 2 insertions and 1 omission.

Words that are pronounced correctly (sounded out and blended) are marked as ‘Mispronounced’ – which may be due to the pronunciation of younger students.

Student said, ‘The yap… yapping” – It was marked as 3 insertions.

Student said, “She h – ol … holds….”

Only seems to recognise repetitions of single words – not phrases or sentences. In this instance, the child sounded out a lot of words, repeated them and then reread the whole sentence correctly. Instead of marking this as correct, the students received a large number of errors (insertions).

Student repeated, “There are” – was marked as an insertion rather than a repetition.

Student clearly said, ‘Beginning’ – was marked as correct. Setting is on lowest sensitivity.

For one of the higher achieving Year 1 students (she can read fluently) it worked quite well. I did still have to make some changes, however there was only a few. So, this would probably work very well for Year 3+ with more confident and fluent readers, who only make a couple of errors. However, I did still need to go through her recording to listen to it and adjust some of the errors manually. So not sure how much time it would save.
The Reading Coach – very sensitive – students will repeat the word numerous times, but it still won’t accept it. I tried myself and it did not like the way I pronounced the words – it kept telling me I had it incorrect.
