The curriculum development process involves piloting the offerings at various stages of development to enable iterative feedback and formative evaluation of the design. The first such endeavour attempted by CLIx was the i2C pilot in Telangana and Rajasthan schools, in 2015. This has offered rich learning not only for the i2C team but for the other CLIx curricular teams as well. Through this process we were able to identify the need to distinguish technological, pedagogical and content elements, in order to to separately evaluate each aspect. At the same time, when we analysed their inter-relationships, the design aspects to be considered for implementation at scale became clearly visible.
