Code Bits: An Inexpensive Tangible Computational Thinking Toolkit For K-12 Curriculum

The extensive research in the domain of computational thinking has identified itself as one of the critical skills that needs to be a part of regular K-12 curriculum. However, most of the tangible computational thinking toolkits that are being developed are bulky and expensive to be deployed in classroom environments. In this paper we present Code Bits, a paper based tangible computational thinking toolkit that is inexpensive, portable and scalable. The students create programs using the tangible paper bits on any flat surface and use the Code Bits mobile application to process the code, which runs on any android device with a camera and uses augmented reality based games to improve the computational thinking skills of the students. The toolkit has been designed in way so as to promote collaboration amongst students.
