Anchored instruction does not imply that instruction needs to reflect actual situations with 100% fidelity. The maturity and ability of the learners and the nature of the content must be taken into consideration when creating a context for the instruction. The role of the instructor is contingent on how much complexity and detail is necessary to make the learning activities meaningful. Students have to learn to deal with a variety of stimuli within the context. Unfortunately, this is often a difficult leap for students because their typical higher education classroom-based problem solving activities have required them to deal with and handle only a limited set of stimuli in a decontextualized situation. In other words, students are used to solving the same simplified, decontextualized problems in the same way, over and over again. But, in anchored instruction, the students must learn to handle and work with authentic problems that have the natural complexity and ill-structuredness of actual problems. Therefore, the amount of scaffolding that the instructor must provide varies, depending on the previous problem-solving experiences students have been exposed to and the level of complexity and ill-structuredness of the problems they now have to tackle.
