The contribution of the proposed research is the innovation of computing and mobile phone tools for enhancing English literacy. Low English literacy impedes well-being for several populations. Past studies have demonstrated the value of technology in enhancing literacy. We propose to build on this work to create a suite of tools that are targeted specifically towards children and towards adults in different cultures to improve their English literacy. Specifically, we will explore answers to the following questions: 1. What features are required for computer-based tools and games to enhance English literacy education, taking into consideration available resources and education practices for children and adults from different parts of the world? 2. What tools and games work best in different modalities (for example, mobile phones versus laptop or desktop computers) and best use popular tools in society? 3. What content, exercises, and games will meaningfully enhance English literacy skills, and how can we enable easy customization of content to be relevant in different cultures? Through this work, we will advance the state-of-the-art in educational technology by developing and field testing innovative tools and games designed to improve literacy among children and among adults in several countries including Qatar, the United States, and some developing countries. Our work will advance the state-of-the-art in computer-assisted language learning and technology for development.
