Description
The authors examine the promise, usability, and feasibility of an intelligent tutoring system to improve the vocabulary and language proficiency in science and social studies of Latinx second-grade English learners. Participants were 217 English learners attending English-only programs or bilingual programs. Findings from the clustered randomized control trial using a researcher-developed proximal assessment indicated that students who used the intelligent tutoring system significantly improved their vocabulary knowledge of the words taught compared to students in the comparison group (ES = 0.38). Results also indicated that most students enjoyed using the intelligent tutoring system and learning new words. Teachers found the program feasible and beneficial to their students.
