Weld et al.  discussed personalized online education in crowdsourcing. They suggested maximizing learners’ skills, whereas the typical goal in crowdsourcing is minimizing the costs to obtain high quality results.

RABJ tried to educate workers by selecting managers from the workers. These managers are responsible for creating task-specific guidelines and validating workers’ output.

Although some studies have proposed frameworks to solve complex tasks via micro-tasking, they paid little attention to skill development.

This paper proposed a micro-tasking framework that supports skill development of individual workers. Researchers designed the framework based on the review of two micro-tasking projects we have conducted. It consists of four key components, a tutorial generator, a task dispatcher, a feedback visualizer, and a skill assessment engine. The framework will help developers create sustainable micro-tasking systems

In Crowdwork, the quality of the outcomes is controlled by filtering for workers who have higher skills, without considering the development of the individual workers’ skills. However, if micro-tasking systems support skill development, they can produce outcomes of higher-quality and make their use more sustainable, expanding the new labor market.

Researchers describe two micro-tasking projects conducted and analyze them to clarify the requirements for our framework. The two projects have similar implications for the skill development of the workers. These implications span many of the issues discussed in existing crowdsourcing research.
