Guiding students to do remedial learning in school campus with learning objects' spatial relations

There are more and more students learning in the real environment. Remedial learning is an educational process of providing supplemental learning materials and directions to students according to their learning assessment results. Due to the ubiquitous learning environment may have numerous and various learning objects, for example, a garden in the school campus, how to plan an effective path for students doing remedial learning activities and searching the supplemental learning objects is very important. This paper proposes a method to plan a shortest path for students when they are doing remedial learning activities outside of the classrooms, for example, in the school campus. The shortest remedial learning path planner applies Formal Concept Analysis (FCA) to build learning scenes for students; uses spatial relation map to switch learning scenes for students; uses one-third theory to decide learning priority of the concepts students have to learn; and, finally generates shortest paths for students doing remedial learning activities. At the end of this paper, an example with many rounds shows how to plan a shortest path and switch the learning scenes for students when they are doing remedial learning activities of elementary school's botanical learning unit.
