VIEW is an intelligent computer-assisted language learning (ICALL) system designed to provide supplementary language learning activity resources to language learners. It can be viewed as an intelligent automatic workbook, providing an unlimited number of activities designed to foster awareness of English grammatical forms and functions. Because it is a web-based system, it can be used anywhere there is a computer with internet access.
The VIEW activities are automatically derived from authentic texts, obtained from any web page of interest. The task of retrieving texts appropriate for learners is handled by a separate Information Retrieval for Language Learning (IR4LL) project.
VIEW uses state-of-the-art Natural Language Processing (NLP) technology to generate exercises, identifying targeted lexical and phrasal material through a combination of tokenization, lemmatization, morphological analysis, part-of-speech tagging, chunking, and parsing.
The activity types VIEW provides follow a pedagogically motivated progression from receptive presentation, to productive presentation, to controlled practice. Specifically, activities include the coloring of targeted forms, having the learner find and click on targeted forms, and finally, controlled practice activities such as multiple choice, fill-in-the-blank, or editing tasks. VIEW provides these activity progressions for a variety of grammar topics.
VIEW History
VIEW is a multilingual extension of the WERTi system (Working with English Real Texts), which has been under development since 2006.
The original WERTi system was designed by Detmar Meurers, Vanessa Metcalf, Luiz Amaral, Chris Kovach, and Cory Shain at Ohio State University. Work on WERTi continued at the University of Tübingen after Detmar moved there in 2008. The original Python-based code was ported to Java and the UIMA framework by Aleksandar Dimitrov and developed further by Niels Ott and Ramon Ziai. A demo of the first Java version is available for reference. In 2010, Adriane Boyd developed the firefox extension, which improves usability and compatibility, in particular for web pages with dynamically-generated content and special session handling.
We are continually working on new topics and activities and are grateful for ideas and contributions in this area from Magdalena Leshtanska, Emma Li, Iliana Simova, Maria Tchalakova, and Tatiana Vodolazova.
