  Informal learning procedures have been changing extremely fast over the
recent decades not only due to the advent of online learning, but also due to
changes in what humans need to learn to meet their various life and career
goals. Consequently, online, educational platforms are expected to provide
personalized, up-to-date curricula to assist learners. Therefore, in this
paper, we propose an Artificial Intelligence (AI) and Crowdsourcing based
approach to create and update curricula for individual learners. We show the
design of this curriculum development system prototype, in which contributors
receive AI-based recommendations to be able to define and update high-level
learning goals, skills, and learning topics together with associated learning
content. This curriculum development system was also integrated into our
personalized online learning platform. To evaluate our prototype we compared
experts' opinion with our system's recommendations, and resulted in 89%, 79%,
and 93% F1-scores when recommending skills, learning topics, and educational
materials respectively. Also, we interviewed eight senior level experts from
educational institutions and career consulting organizations. Interviewees
agreed that our curriculum development method has high potential to support
authoring activities in dynamic, personalized learning environments.
