How the data should be described
CDIs
Each student will receive a specific number (subject ID) throughout the intervention. The list of names and numbers will be stored in a locked filing cabinet in a locked office where only the researcher has the key. The numbered data will be stored in another locked filing cabinet, i.e., separate from the list with names and numbers. All tests carried out, the registration forms, and the CDIs will be marked with the students subject ID from the randomization list.The data that will appear on each test will list the number of correct and incorrect responses. The data that will appear on student forms from each work session will list also the correct and incorrect responses as well as the time used. It is particularly important to measure the students work progress, because they have to achieve at least 80% correct responses before they can move on to the next folder.The data that will be collected on social validity will inform the researchers whether the students have liked working on the reading program and if they would like to continue. For children who use AAC to communicate, assessing consumer satisfaction should involve the AAC user to the greatest extent possible [
