The ability to observe a class and make these decisions is not a skill that comes easily. As with many of the pedagogical skills, it takes time and practice. In the beginning it is helpful to have several cues in mind and then scan the class to determine which of the refinements will benefit the class. If the majority of the students are gripping their rackets correctly, then it is of little use to explain the grip to the entire class. It can be done individually. In contrast, if the children are swinging their rackets in uneven pathways causing them to miss or mis-hit the ball, then time needs to be spent on their swing pathways. This is a decision best made through observation, however.
