The paper presented examines how the combination of LEGO bricks and an interactive tablet can be designed using participatory design with children, to create technology that delivers engaging feedback for children ages 5-7 years old, within an educational context. It presents a participatory design workshop that was carried out with a group of eight children between the ages of 11-13 years. The study utilised the research method of participatory design (PD), as it provides researchers with the opportunity to “enhance technology for children by designing with children” (Yip et al., 2013). The overall aim of this study is to create a proof of concept prototype based on the designs gathered from the participatory design workshop with the children. A thematic analysis draws out themes that emerge from the rich, qualitative data. The contribution is an educational system, which involves digital technology used as feedback to undertake LEGO Education’s 4Cs constructionist learning using LEGO.
