FeedBook Developing an interactive workbook for English foreign language teaching

FeedBook will provide individual, intelligent feedback for students working in a web-based workbook. While working with FeedBook at home students receive hints regarding form and meaning, just as a tutor would provide hints. This enables a stepwise understanding of the concepts and mastering of the exercise. Based on the learning gains students achieve at home teachers can focus their classes more on communicative and task-based activities, while at the same time being informed about what issues their students face at the moment.


The FeedBook is an intelligent electronic workbook is designed to accompany the English teaching at the German Gymnasium. It is developed by computational linguists at the University of Tübingen in collaboration with the publisher Diesterweg on the basis of a current workbook for 7th grade English classes, Camden Town.

The main goal of the FeedBook is to develop a system that provides immediate, individualized feedback to English language learners working on a range of tasks. To provide this kind of scaffolding feedback, state-of-the-art compuational analyses of meaning and form are implemented and further developed.

A first version of the FeedBook is already used and tested at 4 German schools, containing 55 exercises. These include fill-in-the-blank and reading comprehension exercises that cover the entire English curriculum for the 7th grade at the Gymnasium.


The University of Tübingen is one of the oldest universities in Europe and one out of only 11 excellence universities in Germany. It hosts the project and provides financial resources.

Diesterweg is a publisher of educational materials. They manage the pilot classes and provide the materials used as a basis for the digital form.

The development of the FeedBook is funded through the Knowledge Transfer Project (T1) as part of the of the collaborative research center 833 "The Construction of Meaning". The computational analyses implemented in the FeedBook are based on research results of the SFB Project A4 (Comparing Meaning in Context) on state-of-the-art meaning assessment of learner answers.
