The document discusses contrived experiences in teaching and learning. It defines contrived experiences as representative models or mock-ups of reality used for practical reasons to make real life accessible to students. Some examples of contrived experiences mentioned are models, mock-ups, specimens, simulations, games, and objects. The purposes of using contrived experiences in teaching are to overcome limitations of space and time, edit reality to focus on specific parts or processes, overcome difficulties of size, understand inaccessible concepts, and help students understand abstractions.
