Model of Learning Assessment to Measure Student Learning: Inferring of Concept State of Cognitive Skill Level in Concept Space

This research presents a novel learning assessment model to measure student learning in terms of learning cognitive skill levels and the current concept state towards achieving the level. The cognitive skill levels refer to levels such as whether a student has acquired the concept at the level of understanding, or applying, or analyzing, or evaluating, or creating. The concept state refers to whether a student has already learned, or is ready to learn, or is not ready to learn a certain concept. The model is comprised of four constructions: graph paradigm of a semantic/ontological scheme, concept mapped testing and evaluation method, analysis algorithms and methods which produce the sets of concept states, and the assessment analytics, which is the process to estimate the students' concept states. The concept states involved three basic sets of the concepts in the domain: Verified Skills (VS), Derived Skills (DS), and Potential Skills (PS). VS means the concepts are known by evidence. DS means the concepts are known by inference. PS means the concepts are ready to be known by inference. The experiment is conducted to validate the accuracy of the concept states VS, DS, and PS.
