It can be used in contexts related to scientific, philosophical, or theoretical discussions where a theory is currently being applied or tested.
Example: "The researchers are currently working on an active theory that explains the behavior of dark matter in the universe."
Alternatives: "dynamic theory" or "current theory".

Firstly, based on stability criterion of linear system, chaotic synchronization is achieved with the help of the active theory, and accordingly, the simulation results are given for verifying the feasibility of the method.
Yet in some writings, Baudrillard has a somewhat more active theory of consumption than that of the Frankfurt School's that generally portrays consumption as a passive mode of social integration.
This new view of learning, operant conditioning (for the organism is "operating" on its environment) was not merely the passive learning of Pavlov, but a species-nonspecific, general, active theory of learning.
