Which term describes a measurable change in a learner's knowledge due to interaction with an electronic device?

The term that accurately describes a measurable change in a learner's knowledge due to interaction with an electronic device is eLearning. This concept specifically pertains to learning that occurs through electronic means, often utilizing internet platforms and technology-enhanced resources. eLearning focuses on the interaction between the learner and the technology, and it is measured through assessments and evaluations that demonstrate improvements in knowledge or skills.

In the context of the other options, digital learning generally encompasses a broader category of learning that involves any digital tools but may not specifically focus on measurable changes in knowledge. Virtual learning typically refers to environments that simulate physical classrooms but doesn't inherently emphasize interaction with the device itself. Online learning, while closely related, primarily describes the format of instruction rather than the specific impact on the learner’s knowledge. Therefore, eLearning is the most precise term that indicates both the medium of learning and the evaluable outcomes of that interaction.
