In this paper we deal with constructive mobile learning, i.e., a positive approach to combining learning with moving, field education with ICT, personalized and learner-enhanced learning material. Technically it is based on location dependency of educational content and method and desegregates moving and information processing for a learner community. A comprehensive example for a 101 grade class studying history coupled with several interdisciplinary educational goals is given. Analysis and organization of information leads to the specification of m-learning objects dynamically created based on learner's location, movement, learners' profile and curriculum.
