Abstract: In accordance with some embodiments of the present disclosure, an apparatus for adaptive learning is provided. The apparatus may include a memory and a processing device. The processing device is configured to receive a user input providing a portion of an annotation to be associated with a practice problem and a user; identify one or more knowledge components relating to the user input; and autocomplete the annotation to include information of one or more of the knowledge components. The information of the one or more of the knowledge components may include at least one of a definition of a first knowledge component of the knowledge components relating to the first user input or an equation relating to the first knowledge component. In some embodiments, the knowledge components relating to the user input are identified by processing the user input using a trained machine learning model configured to recognize knowledge components.
