MiniMandarinHowler is a mobile language learning tool for Mandarin designed to promote reflective accommodation and assimilation of vocabulary. Using an electronic dictionary interface to encourage usage, the program exposes the relations between different words to the user in a way that encourages mental links and differentiations between words, based on ideas from Constructivism and Connectivism. An evaluation approach is described to attempt to detect if reflection-in-action or on-action occurs while using mobile devices. Possible modifications are then discussed to enhance the reflective potential.
