Students are more likely to participate in an activity when

While challenging activities can motivate some students, they may discourage others who lack the necessary skills or confidence to engage. If the challenge is perceived as too difficult, it can lead to frustration and disengagement rather than participation.

An activity that is too easy might not capture students' interest or push them to engage meaningfully. While it can encourage participation among some, it may not provide the stimulation needed for all students to actively participate, especially those seeking growth or challenge.

This choice implies a lack of effort or challenge, which can lead to boredom and disinterest. While some students may prefer low-effort activities, this does not universally promote participation; many students are motivated by a sense of accomplishment that comes from engaging in more demanding tasks.
