The prototype is extensively used in Design Thinking as a method to test theories, to negate the fear of failure and iterate based on valuable feedback from the user.
At Atisa, we used prototyping as a tool for the tactile experience. Here the creator was an involved owner of the subject. The closest we came to constructionism is with prototyping. As an extension of the previous project of visualization, now we asked the children to create prototypes of the gifts desired by their partner which they presented to the class.
They were provided with limited stationery (because of budgets) and asked to improvise whenever required. At first, they were reluctant to use the material. The lack of familiarity with tactile experience and the predisposed notion of thinking with instructions made them very uncomfortable. Most wanted to look for options like drawing, writing, etc. However, there was much explanation made to quench the inquisitive minds. The results were unexpected, and of course, they were proud to have created something that was appreciated by their partners.
