PECS Phase III App

Based on research from the field of Applied Behavior Analysis (ABA), the PECS™ protocol details a specific discrimination teaching strategy in Phase III. The PECS Phase III app is an invaluable tool that allows you to implement the teaching of Phase III of PECS™ and offers a novel approach to providing new opportunities for learners to practice discrimination techniques and strategies.
The app, designed to look just like a PECS™ communication book permits a teacher to practice picture discrimination with one or several learners within a single session. Touching the correct icon results in immediate visual and auditory feedback from the device in a manner far quicker than a teacher could react. If the learner touches an incorrect icon, there is no significant feedback. A correct picture selection results in access to a desire item or activity!

For teaching simple discrimination, the learner selects from an array involving the target picture versus a distracter picture. Both options allow you to move the pictures around on the page, between trials and to vary the number of pictures per trial from 2 to 12. A Correspondence Check™ can be tested by arranging two or more equally valued items and corresponding pictures with strategies from the Phase IIIB PECS™ protocol.

*App is not intended to replace your PECS communication book and/or to serve as a standalone communication system.

Features include;
-Over 100 Pics for PECS™ images
-Male and female voice with on/off option
-Customizable Library with your own pictures
-Visual guide to the 4-Step Error Correction Procedure and Correspondence Checks

I love PECS Phase III! ,

I love this app!

I love this app! While this app is not a stand-alone communication device, it has been so helpful in teaching picture discrimination to my students. The app comes pre-stocked with 100 images which are great, but I love that I can add my own images. You can record audio for any image you add as well as re-record the audio for pre-stocked images. This is certainly a nice feature! The app allows you to customize the images and the tabbed insert pages. With the images, I've been able to adjust the size and display picture and text, picture only and/or text only for each image. With the insert pages, I've been able to change the color, change the number of velcro strips per page and adjust the spacing between the strips as needed.

I also love that there are visual cheat sheets for correspondence checks and the 4-step error correction! This comes in handy when I need a reminder!

Thanks to Pyramid for creating such a wonderful and useful app! Can't wait to see what they come up with next!

Love it!

We use PECS in our classroom. This app seems like the perfect transition to a voice output program. It is easy to manage for the children and they are able to generalize the skills they have learned from the PECS book to this. We would love it if there was a sentence strip at the bottom so the children can build sentences.

great start!

i purchased after reading the info, we have other apps for my nonverbal son but he has had the same PECs book for 6 years and i thought that he would see familiar things. i am excited that pryamid is in creation mode and i think this app works great on the basics. my son does discriminate and we are using this app more and more i dont know how to make the nest phase work like a real book but i can't wait to see what is next!
