TAGARELA is an intelligent computer-assisted language learning (ICALL) system designed to be fully integrated into the Portuguese Individualized Instruction Program at The Ohio State University. It can be viewed as an intelligent automatic workbook that provides students with opportunities to practice their reading, listening, and writing skills. Because it is a web-based system, it can be used anywhere there is a computer with internet access. TAGARELA uses state-of-the-art Natural Language Processing (NLP) technology to analyze students' input, and detect spelling, morphological, syntactic and semantic errors. Its NLP components allow the system to handle activities that go beyond the usual multiple choice or fill-in-the-blanks used by regular CALL systems. Its exercise types are similar to the ones typically found in current workbooks, such as: * listening and reading comprehension * picture description * vocabulary practice * phrasing and re-writing TAGARELA has a student model that keeps track of each student's individual performance, and an instructor model that carries information about activity and error types. Together the student and instructor models allow the system to choose the best feedback strategy to use with each individual learner based on the level of the activity, type of task, characteristics of error, and learner profile.
