Specicically, the study aims to test AI companion for solving these three sets of Fermi problems and seek the ways of extending the solution categorization framework proposed by Albarracín and Gorgorió (2014), which puts forward a theoretical implication for further research with Fermi problems.enGesellschaft für Didaktik der MathematikBeiträge zum Mathematikunterricht; 58ProblemlösenModellierenMathematik im AlltagKünstliche IntelligenzExplorative Studie510ConferencePaper
