Love it!

Discrete Trial Training (DTT) Letters is a great app to utilize while teaching receptive letter identification. DTT is the primary teaching method used in Applied Behavior Analysis to teach multiple skills to children with autism, so this is a great tool to support teaching. This app is customizable with the ability to choose correct and incorrect letter cards the child is learning, allowing the target letters to be randomized. Upper or lower case letters can be chosen, as well as a variety of fonts and styles. DTT Letters also allows the instructor to change the number of stimuli in a field and it offers pictures of the American Sign Language letters. One of the most helpful things about this app is that it has the ability to track and record student progress. This log provides individual student records broken down by date, shows the letters that were presented for each trial, and the number of cards in a field. The DTT Letters app is a great way to keep students motivated and engaged while learning their letters!

Great app! Wish I could add more names so that I can review data for each student. Is that possible in your next update. Six children would be perfect for most teachers! A must have app for a special education k-2 class!

Great app!

This is much easier than having flashcards! I like all the choices that can be made as to how I want the program to work. Great app for teaching any child, special needs or not!
