Teachers can minimize the avoidance reaction in a child learning to catch a ball by having the child practice with which object?

Using a yarn ball to help a child learn to catch is effective because it is soft, lightweight, and typically larger than a standard baseball or tennis ball. This reduces the fear associated with catching a ball that might be perceived as hard or potentially painful upon impact. The yarn ball allows the child to gain confidence in their catching ability without the added pressure or fear of getting hurt, thereby minimizing the avoidance reaction.

When children practice with a softer object, they can focus more on developing their motor skills and hand-eye coordination without the distraction of anxiety that might come from using a harder, heavier ball. This supportive approach enables them to build confidence gradually, which is crucial when mastering a new skill like catching. In contrast, the other options, such as a tennis ball, basketball, or football, are generally firmer and may trigger an avoidance response due to their weight or hardness, making them less effective for beginner learners who may lack confidence.
