Abstract
Video analysis is one of the computer resources used to develop experimental activities in the teaching of Physics. It carries particular features that enables users to examine real physical systems in a virtual environment and model the changes that take place in such real physical systems. This current research paper aimed to design and implement experimental investigations assisted by video analysis in order to enhance learner performance through the exploration of real physical systems with the aid of the systematization of an experimental research procedure. As an example, the modeling of an activity is offered which is based on the need of determining the water consumption of a real-world physical system. The methodology used consisted of assessing learner performance using different assessment activities such as pedagogical tests and observations. The statistical processing of results showed significant differences regarding learner performance comparing the learning results before and after the execution of the designed experimental activities.
