Intuitive Interaction Interfaces for Elementary Mathematics Objectives, achievements and challenges Work Package 3 has a rather ambitious objective: The design and development of innovative and intuitive interaction interfaces for Elementary Mathematics, including voice and direct manipulation user interfaces. The achievement of this objective results through the following steps: Provision of speech production and voice recognition…
Fractions Misconceptions and Thinking-in-Change: Samuel and the Equivalent Fractions Misconceptions are a bi-product of children developing their own connections as they experience mathematics in school and in the world around them (Hansen, 2012, 2014). In the iTalk2Learn project we are designing tasks and task-dependent support for the exploratory learning environment, Fractions Lab (see WP3 news…
In an earlier blog post, iTalk2Learn partner, Sail, talked about the statistical nature of the two models which are employed for automatic speech recognition: The acoustic model The language model These models need to be trained on a so-called ‘corpus’ before they can be used in the recognition process. In this blog post, we’ll hear more from Sail…
iTalk2Learn partners, Birkbeck College (BBK) and the Institute of Education (IOE), went back to a school in Lancaster to run Wizard-of-Oz studies to investigate how speech can be used to tailor feedback. At IOE and BBK, we were particularly interested in how the affective state of a student can be detected through speech and other interactions with the platform,…
At the Ruhr-Universität Bochum, we’ve had a very exciting couple of weeks. We’ve taken Fractions Lab into German schools for the first time! Given the differences we had discovered between students in Germany and students in the UK when working with Fractions Tutor, we were very curious to see how German students’ react to this new state…
