BKT

BKT is an acronym that can refer to more than one topic. In scholarly and technical discussions, it most often denotes Bayesian Knowledge Tracing; in industry, it can refer to Balkrishna Industries Limited, a tire manufacturer known by its brand name BKT.

Bayesian Knowledge Tracing (BKT) is a probabilistic model used in educational data mining to estimate a learner's mastery of knowledge components over time. It represents each skill as a hidden binary state (known or not known) that evolves as the learner practices. The model updates the probability of mastery after each observed response using Bayes' rule, conditioned on whether the answer is correct; it can incorporate factors such as guessing and slipping. BKT produces a trajectory of estimated mastery for each skill, which can be used to tailor instruction, select subsequent exercises, or evaluate learning progress. The approach was introduced by Corbett and Anderson in 1994 as part of intelligent tutoring system research and has since influenced subsequent models of student knowledge. Limitations include assumptions of a single skill per question, independence between skills, and static skill definitions; extensions and alternative models have sought to address these constraints by combining multiple skills, time-dependent effects, or richer representations of student knowledge.

Balkrishna Industries Limited (BKT) is an Indian multinational tire manufacturer that specializes in off-highway tires for agricultural, industrial, and earthmoving applications. The company markets its products under the BKT brand and operates manufacturing plants in India, with a global distribution network serving customers around the world. BKT has grown through product diversification and international expansion, positioning itself as a major supplier in the global heavy-equipment tire segment.
