Core team and honorary members.
Willem-Jan Renger
Expert/Designer · Senior researcher
Designer, researcher and educator specialising in Ludodidactiek: designing meaningful learning through play. Willem-Jan bridges theory and practice across education, culture and organisations. He combines rigorous analysis with playful experimentation to help teams build engaging, resilient learning experiences. Founder of Ludodidactiek.
Evert Hoogendoorn
Expert/Designer · Playful Learning
Designer, educator and co-author of Ludodidactiek. Evert works at the intersection of game design, education and innovation, translating complex ideas into concrete ludodidactic experiences. He has partnered with Willem-Jan since the early development of the method.
Eva Den Heijer
Visual artist · Game & educational design
Visual artist, play designer and educator. Eva combines strong aesthetics with sharp didactic insight. A veteran in the team, she contributed to the wider research community through her Comenius Grant work and continues to pioneer Ludodidactiek in practice.
Robert Stieltjes
Docent Ludodidactiek (HKU) · iPabo
Teacher trainer at iPabo and Ludodidactiek instructor at HKU. Robert pushes boundaries in teacher education and pioneered a large-scale Ludodidactiek implementation in the iPabo curriculum. As one of the earliest team members, his mountaineering spirit keeps the work ambitious and grounded.
Floor Roos
Docent beeldende kunst & vormgeving
Artist and gifted teacher. Floor’s friendly demeanour hides a sharp mind and wit—students encounter it when they need feedback but struggle to accept it. A long-standing team member, she teaches what she preaches and brings craft, clarity and courage to the work.
Jessica de Schipper
Management assistant (HKU)
Management assistant at HKU Creative Transformation. Jessica keeps our work running: organiser, guardian angel and practical anchor. When programmes cross weekends and evenings, she is there—coordinating, communicating and safeguarding the details. Without her, we would fail utterly.
Frank Leone van der Weert
Assistant professor · Professional learning & technology
Assistant professor and one of our Academic Field Agents. Frank brings Ludodidactiek into academia and keeps sharpening the method with research and practice. His game ‘Social Fabric’ became a highlight in our summer school; his wit and critical eye push us further.
Lorenz Boeckhorst
PhD student · Teacher trainer
Our first Academic Field Agent. Lorenz is known for designing sophisticated learning games—famously, one with six dice. He is currently doing a PhD in this field and is building an academic track for Ludodidactiek that connects rigorous research to classroom practice.
Ina van de Brug
Honorary member
Before Jessica took over, Ina was the steady guardian angel of Ludodidactiek—present even when it was still called Creative Design for Motivational Learning and Transfer. Now retired, her name remains connected to the roots of the programme.
Thijs Spook
Team leader (De Werkplaats)
Team leader at De Werkplaats Kindergemeenschap. Thijs pioneered Ludodidactiek in music education and developed so many successful games that he ‘bored himself’ out of the teacher role. When his career moved into management he stepped back, but his ability to organise playtests remains legendary.
