Conceptual crowdsourcing models for e-learning

Crowdsourcing tools have improved e-learning over the last few years. However, these tools vary in many aspects. This work discusses and analyzes the basic e-learning processes based on these tools, defining ways to classify them through these processes. Finally, we define conceptual models tailored to each type of process, using a standard notation for software development. These conceptual models may be used to build new e-learning crowdsourcing tools.
