Paper Abstract:	In the context of learning platforms for on-the-job training, we expect from an intelligent tutoring system (ITS) that it effectively brings learners to the learning program that suits their aspirations and ambitions and guides them through an individual course or even their entire course program. The better the ITS "understands" the learners' goals, behavior, misconceptions, and errors, the better it can guide the learners along their learning journey, and the more effectively learners acquire their desired knowledge. Guidance usually includes observation of learners, evaluation of their behavior, which leads to the analysis and evaluation of their input, and eventually provides helpful and useful feedback to the learners. Digital learning platforms increasingly focus on self-paced or self-directed learning, which gives learners the freedom to learn whenever they want and at whatever learning pace that suits their personal learning preferences and attitudes. This trend fosters a shift away from predefined and rigidly wired sessions towards flexibly arranged learning nuggets and tests. There are different paradigms for the design of learner guidance or instructions in ITS. This paper draws attention to natural language (NL) as the prominent mean of communication between system and learners. The benefits of emphasizing natural language bring a number of benefits for guiding and instructing learners. The paper describes the architecture and design of an ITS in the context of a prototypical platform for self-paced learning and demonstrates the role and importance of natural language processing (NLP) as key technology for learner guidance and instruction.
