tMAIL is a mobile training app, targeted at primary school teachers, intended to help implement classroom practices that stimulate students’ autonomy and self-regulated learning. It will help you turn your students into self-regulated learners who can make their goals come true. It has 30 short courses that you can take where and whenever you like. We'll invite you to actually try out some things in your classroom. When we want our students to self-regulate, we may as well start with ourselves, be ready to use your own self-regulation skills. We believe every student and teacher is unique, so we will personalise your learning by encouraging you to follow the training in a way that best suits you, and we'll monitor & visualise your learning. tMAIL supports English, Dutch and Spanish. tMAIL is currently in pilot phase in the UK, Spain and Flanders.

The human augmented reality heart is a unique application designed to support and enhance the learning of the structure and function of the heart as part of the Open University modules, or as a stand-alone app. The app consists of an anatomically accurate heart which can be viewed in three dimensions, in cross section and also as a ‘zoomed in’ virtual exploration. The app has a range of functions to help develop the learning and understanding of how the heart beats and the cardiac cycle. By selecting ‘Show pins’ all the major anatomical structures of the human heart are identified and selecting a pin provides the name and description. There is the option to show the blood flow through the heart. All the options are available as a stationary or beating heart, the rate of which can be fully adjusted aiding the understanding of the mechanical events of the heartbeat. The app will help students at all educational levels to develop and extend their knowledge and understanding of the heartbeat.
