Shape Coding by Susan Ebbels® is a flexible app designed for teachers and speech and language therapists / pathologists to use with children and young people who are having difficulties producing and understanding English sentence structure and grammar. It uses the SHAPE CODING® system which has been show in several research projects to help children and young people with language disorders increase the length and complexity of sentences they can understand and use and improve the accuracy of their sentence production. The SHAPE CODING® system and this app is designed primarily for children and young people with language disorders aged 7-20 years, but the system has also been successfully used with younger children, children with intellectual disability, including those with Down syndrome and adults with acquired aphasia.

The SHAPE CODING® system uses a visual coding system to show the rules for how words are put together in sentences, to develop the child’s understanding of spoken and written grammar and to develop their ability to use grammar successfully to express themselves. The system includes use of colours (parts of speech), arrows (tense and aspect), lines (singular and plural) and shapes (syntactic structure). These are all included in the app, but the professional controlling the app can choose which features display for individual students.

Multiple “teachers” can use the app and each “teacher” can have multiple students. The app is personalised for each student. The app is designed to be flexible so that professionals can adapt the levels and information displayed to suit the current levels and targets of individual students. There is no prescribed order of levels to work through, but the default first setting for each new student includes only basic sentence structures. Further complexity can be turned on (and off) by the “teacher” and individual settings are preserved for each student between uses.
The app is equipped with a basic set of words which can be inserted into the shapes to make sentences. However, additional words can be added for individual students, or indeed for all students working with a particular “teacher” (this can be useful for names and topics which are common across a class of students for example). These can either be added before a session with a student, or during a session and can be saved for future uses.
The app uses text-to-speech, so that students who struggle to read can also use the app.

Crashes Every Time

I'd love to review the content of this app but I can't as I can't get past the student login page because it crashes every single time. I use the Shape Coding system a lot and was hoping to use the app to support my SLT clients remotely during the Covid 19 crisis. I have also spent the last half hour trying unsuccessfully to track down a contact for technical support. I don't expect an immediate response under the circumstances but at least an easily accessible email address would be helpful. Really disappointed.


Inconsistent Log on

I think this app is great but after playing around with it for 5 minutes it now won’t let me log back in, standard username/password not recognised appears. I have uninstalled the app and tried again, it works fine on first log in but then won’t let me log back in...???
