NLDB / PLK Framework
A complexity-aware educational perspective for interpreting visible learning signals within broader developmental conditions.
Open frameworkPortfolio Architecture
From conceptual framework to classroom implementation.
This portfolio is organized for teacher education and school development: first the observation framework, then university-level teacher education, followed by a dedicated mathematics education hub, embodied physics and broader science-society transfer.
Educational Observation Framework
Teacher Education & University Teaching
Mathematics Education
Embodied Physics & Science Transfer
Science Dialogue & Public Engagement
Language note: The conceptual framework is presented in English. The applied learning environments, seminar examples and implementation-oriented materials are currently available in German, reflecting their direct use within German-speaking teacher education and school contexts.
Educational Observation Framework
Understanding Learning Development Through Longitudinal Observation
The central framework connects process-oriented competencies, structured observation, developmental trajectories and reflective professional judgment. It supports a shift from isolated performance snapshots toward a more complexity-aware understanding of children’s learning over time.
Children’s learning trajectories
Process competencies
Observation culture
Professional judgment
Cognitive sustainability

PeerLearningKompass WebApp
Structured child observation, learner profiles, QR-based workflow and longitudinal documentation for real classroom settings.
Open WebApp / QR prototypePrintable Introduction
A concise introduction for quick adoption: purpose, observation fields, workflow and next pedagogical steps.
Open PDFTeacher Education & University Teaching
University-level teaching in primary teacher education.
Selected examples of university-level teaching in primary teacher education. They reflect three core pillars of my work: innovative mathematics didactics, research-based cognitive learning design, and reflective professional learning through science transfer. The course designs integrate scientific inquiry and AI-supported tools to reduce cognitive load and strengthen meaningful professional reflection.
Gute Aufgaben – guter Unterricht
Task quality, productive practice, reflective planning and competence-oriented mathematics teaching.
Open pageDidaktische Konzepte Arithmetik
Arithmetic structures, flexible calculation strategies and the transition from insight to diagnostic teaching.
Open pageReflexionsseminar
Organization, reflection and professionalization in teacher education with clear institutional relevance.
Open pageMathematics Education
Mathematics is not a subject. It is a way of understanding the world.
A dedicated mathematics education hub presents the complete architecture of this work: Premium Tasks, family mathematical ecology, 21 research-based learning environments, embodied cognition, observation culture and primary teacher education.
Dedicated Hub
Mathematics Education for a Complex World
Exploring how children develop mathematical understanding through participation, observation, movement, modelling and reflection.
Open Mathematics Education
What the page includes
12 Premium Mathematics Tasks · Family Mathematical Ecology · 21 Learning Environments
Tasks that make mathematical thinking visible
Classroom-ready task environments designed around modelling, reasoning, representation, communication and problem solving.
Open tasksMathematics as lived experience
Everyday life, family participation, movement, nature, health, art, music and ecological systems as mathematical learning spaces.
Open environmentsFrom observation to understanding
A research-based perspective connecting mathematics education with observation culture, human development and complexity-aware educational systems.
Open research perspectiveEmbodied Physics & Science Transfer
Physics as lived experience.
Research-based educational formats that translate physical phenomena into embodied experience, nature-based exploration and scientific thinking.
Education in movement, nature and everyday life
Embodied learning, outdoor exploration, real-world phenomena and scientifically grounded educational transfer.
Explore Physics LearningMARÉS
Portuguese for tides
An international science-learning experience developed in Pernambuco, Brazil, where the highly dynamic equatorial environment provides a living laboratory for embodied scientific observation and physics learning.
Explore MARÉSScience Dialogue & Public Engagement
Education as a bridge between scientific excellence, culture and human development.
Public dialogue formats connect science with questions of meaning, culture, art, religion, sport and society. They strengthen the portfolio by showing public communication, intercultural dialogue and institutional visibility beyond the classroom.
AstroMum · Education with Excellence
Science. Learning. Human Potential.
This portfolio is designed as a visible transfer space: from scientific thinking to educational innovation, from observation of children’s learning to teacher education, and from concrete learning environments to institutional cooperation.
