Description
This study compared a stimulus fading (SF) procedure with a constant time delay (CTD) procedure for identification of consonant-vowel-consonant (CVC) nonsense words for a participant with autism. An alternating treatments design was utilized through a computer-based format. Receptive identification of target words was evaluated using a computer format and the researcher conducted a generalization probe for expressive identification evaluation. Neither treatment condition resulted in consistent gains on the receptive identification measure. Both treatment conditions resulted in gains on the expressive identification assessment. The SF treatment condition was more efficient due to 1) accuracy in identifying all of the SF target words in fewer sessions than the CTD target words and 2) incidental learning that occurred as a result of exposure to additional SF words as distracter choices and in receptive identification assessments. Implications are discussed.

Description
Many English Language Learner (ELL) children struggle with knowledge of vocabulary and syntax. Enhanced Moved by Reading to Accelerate Comprehension in English (EMBRACE) is an interactive storybook application that teaches children to read by moving pictures on the screen to act out the sentences in the text. However, EMBRACE presents the same level of text to all users, and it is limited in its ability to provide error feedback, as it can only determine whether a user action is right or wrong. EMBRACE could help readers learn more effectively if it personalized its instruction with texts that fit their current reading level and feedback that addresses ways to correct their mistakes. Improvements were made to the system by applying design principles of intelligent tutoring systems (ITSs). The new system added features to track the student’s reading comprehension skills, including vocabulary, syntax, and usability, based on various user actions, as well as features to adapt text complexity and provide more specific error feedback using the skills. A pilot study was conducted with 7 non-ELL students to evaluate the functionality and effectiveness of these features. The results revealed both strengths and weaknesses of the ITS. While skill updates appeared most accurate when users made particular kinds of vocabulary and syntax errors, it was not able to correctly identify other kinds of syntax errors or provide feedback when skill values became too high. Additionally, vocabulary error feedback and adapting the complexity of syntax were helpful, but syntax error feedback and adapting the complexity of vocabulary were not as helpful. Overall, children enjoy using EMBRACE, and building an intelligent tutoring system into the application presents a promising approach to make reading a both fun and effective experience.
