What is DTT?

DTT stands for “Discrete Trial Training” and is a method that teaches the letters of the alphabet in simplified and structured steps. It breaks it down for children, making it easier to learn their alphabet.


Break It Down

Identifying letters is an important skill any child needs, but can be especially important for children with autism and other developmental disorders. If you can learn letters, you can learn words and begin reading!

drBrownsApps has created Dr. Gary Brown’s DTT Letters, an app that helps children learn letters using discrete trial training (DTT). DTT Letter has been tested by Dr. Brown with children who have autism, ADHD, and other developmental disorders.

The DTT Letters app uses audio and many different visuals to keep children engaged and learning.

Choose Your Letters

In the set up, you can choose which letters you’d like to view.

Kids can choose to view letters in a different font, a different color, or as a toy block. These visual options are sure to keep children interested.



Working it Out

When kids get started, they will hear a letter and they are to tap the correct letter.

The screen is simple and easy enough for children to use on their own.

Once they tap the correct letter, reinforcement is given so they know they got it correct.




American Sign Language is also used in this app, which is helpful for children who are familiar with sign language.

They can associate the signed letter to the actual letter and hopefully make a connection when they see the letter again.





Discrete Trial Training and Visual Learners: A Great Match

Kids who are visual learners are sure to benefit from DTT Letters. Practice makes perfect, and this educational technique is no different – with repeated practice using the DTT Letters app, they are bound to learn letters and will also begin building words in no time!

Who’s Behind Autism Plugged In?

My name is Jack Kieffer and I'm a blogger sharing my love of technology at blogs like Cool Gizmo Toys, Greenamajigger, and here at Autism Plugged In where I'm trying to make a difference in the lives of children with autism.

Several years ago, I began volunteering with special needs kids, who gave me much joy and an appreciation for life. This blog is my way of giving back. Any proceeds from this effort are used to support my friends with autism. Read more about Jack or connect with him on Facebook, Twitter, or LinkedIn.
