Each student brings their knowledge, skills, experiences, and dispositions to learning. Navigated Learning employs AI techniques to individualize the learning experience and make individualized learning at scale possible. Navigator curates a catalog of learning activities to compute vectors such as relevance, engagement, and efficacy, and also uses AI techniques to understand each learner to compute their preferences, context, and citizenship. Navigator then uses the science of learning with its curated catalog and real-time understanding of the learner to suggest individualized pathways. Navigator is generalizable across languages, disciplines, and learners.
Navigator goes beyond codifying concepts to structure learning as a progression space (metric space of competencies with partial ordering of dependencies) of competencies that we refer to as the Navigator Competency Framework (NCF). A polyline across domains of competencies for each subject represents a learner's proficiency that we call as their skyline. NCF includes a polyline algebra to compute measures such as route, reroute, and mean-time-to-learn.
NCF enabling AI: The Navigator Competency Framework (NCF) provides a framework for organizing all learning concepts. The NCF details the competency, embeds a variety of curated learning activities, captures each learner's profile, and relates to local norms. We use LDA and word2/doc2-vec embeddings to compute competency models from a set of documents, machine learning techniques on activity stream data to curate learning activities and understand the learner, and principles of learning to personalize pathways. NCF enables AI techniques to personalize learning pathways and provide real-time dashboards to stakeholders.
We structure the vastness of the learning space as a progression space of competencies. Creating the progression space makes it possible for mathematical measures such as route and mean-time-to-learn to be computed. The structure also allows for the implementation of learning sciences research and best practices in teaching and learning.
Factors, such as depth of knowledge, common struggles on a concept, and decay functions, characterize the multidimensional competencies. The Navigator Competency Framework structures the competencies.
There are several facets to learning that relate to the many disciplines, including curriculum, skills, and non-cognitive aspects. These facets are often related. Learner’s performance in science is often associated with their proficiency in Math and their non-cognitive skills. Navigator has detailed and consistent representation of the learner across all of their facets. This enables the suggestion of personalized pathways based on an understanding of the learner.
Big data is captured across distributed systems and offline activities. Machine learning approaches are used to curate the full spectrum of learning resources and activities. As learners interact with materials, learner and activity vectors are continuously updated. We "locate the learner" using a polyline across facets of learning and have developed a polyline Algebra to compute individual pathways and re-route suggestions.
The search engine for learning is based on the structure of the learning space, the curated catalog of learning activities, and an understanding of the user (learner or teacher). We use all of these signals in query analysis and ranking to keep the search results pedagogically aware and personalized.
Operationalizing Science: Navigator encodes Event, Condition, Principles of learning, and Action (ECpA) as a set of models. These model “listens” to events, and based on the condition of a learner, triggers actions, which are suggestions based on the learning principles associated. By operationalizing the learning principles with big-data, Navigator ensures the suggestions offered to learners and their instructors are backed by learning theories and science.
