Abstract: Learning management systems and methods are disclosed. A database arrangement of nodes is generated, the nodes representing respective content. The nodes include respective numeric attributes and weights associated with at least one of a difficulty or a theme of the respective content. A dimensional space is generated based on the database arrangement of the nodes. A first node of the nodes is selected based at least in part on a user characteristic of a user. First content associated with the first node is displayed, and a confidence metric is determined associated with the first content based on a user selection from the user of at least one confidence input mechanism. A user input associated with the first content is evaluated, and a second node of the nodes is selected based at least in part on the user input and the determined confidence metric.

Abstract: There is provided a learning management system comprising: a display; and a processing element in electronic communication with the display, the processing element configured to perform the following operations: generate a plurality of nodes, wherein the nodes correspond to an item of content; implement a testing module that selects a first node of the plurality of nodes to display on the display, wherein the first node outputs to the display one or more questions to a user and prompts the user to select an answer; and implement a confidence metric that prompts the user to select a value corresponding with the user's confidence that the selected answer is correct, wherein the selected answer and the confidence metric value for the first node are used to determine a second node from a plurality of nodes to display to the user next.
