In prior research and development, the project team developed a StoryWorld, a computer-based intervention for English Learners (ELs) that presents children oral and written narratives in English while also providing the information in their first language. With this Phase I funding, the team will develop and test a prototype of a web-based dashboard that provides EL teachers real-time reports on children's progress in areas including for vocabulary, comprehension, fluency, and proficiency. At the end of Phase I, in a pilot study in three first grade classrooms, the researchers will examine whether the prototype functions as planned, is easy to use, and provides information teachers can understand and use to inform their language and literacy instruction?
