By analyzing students’ tree products and oral self-reports, we identified different data-based and context-based approaches to predictor selection and stopping criteria. Students engaged with key ideas of predictive modeling, including classification, model construction, accuracy, generalization, and interpretability. Informal exploration offered rich opportunities for subsequent teaching by enabling students to begin reconstructing central technical ideas and critical tensions of predictive modeling through diverse but meaningful reasoning approaches.</jats:p>"}],"language":[{"iso":"eng"}],"_id":"66074","publisher":"Springer Science and Business Media LLC","main_file_link":[{"url":"https://link.springer.com/article/10.1007/s11858-026-01806-3","open_access":"1"}],"doi":"10.1007/s11858-026-01806-3","user_id":"37888","publication_identifier":{"issn":["1863-9690","1863-9704"]},"author":[{"full_name":"Fleischer, Franz Yannik","last_name":"Fleischer","orcid":"https://orcid.org/0000-0003-0318-0329","first_name":"Franz Yannik","id":"42660"},{"id":"16274","first_name":"Rolf","last_name":"Biehler","full_name":"Biehler, Rolf"}],"year":"2026","status":"public","title":"Informal approaches to predictive modeling: fostering data literacy and critical engagement through decision tree construction","date_updated":"2026-06-29T07:47:44Z","publication_status":"published"}]
