In this model, the pupil is "situated" in the learning experience and knowledge acquisition becomes a part of their learning activity. From their experiences pupils "construct" their own knowledge in various learning situations. The success of situated learning experiences depends upon social interaction and kinesthetic activity. Critical Problem Solving Skill is an intellectual process wherein one skillfully conceptualizes, applies, analyses, synthesises, and evaluates knowledge that was constructed through observation, experience, reflection, reasoning, and communication in order to solve a problem.
