The data collection technique employed will be scientific observation, understood as "the previously planned capture and controlled recording of data with a specific purpose for research, through the visual perception of an event" (Heinemann, 2003, p.135).

Therefore, it is a systematic, controlled, and structured technique of aspects of an event that are relevant to the current topic of study and the theoretical assumptions on which it is based. The fact that it is systematic and controlled means that the observer must consciously direct their attention to specific elements of the event and record those that are relevant for determining the corresponding variables. Structured means that what is perceived is organized, distributed, and documented according to established guidelines (Heinemann, 2003).

Furthermore, this observation must be recordable; it should not rely solely on the observer's intuition. Instead, the data should be recorded as objectively as possible, and for this purpose, recording allows the visualization of the event as many times as necessary.
