Which factor is least likely to influence students' attitudes toward learning?

Homework assignments are least likely to influence students' attitudes toward learning when compared to the other factors listed. While homework can impact a student's perception of their workload or capability in a subject, it typically does not shape their overall attitude toward learning in the same significant way that other factors can.

Parental involvement often creates a foundation for a child's perspective on education by demonstrating the value of learning and providing support. The classroom environment plays a critical role in shaping students’ experiences and can enhance or hinder their engagement and motivation. Similarly, peer relationships can strongly influence a student's interest and attitude toward learning, as social dynamics and friendships often drive a student's desire to participate in educational activities. Therefore, while homework is an important aspect of education, its direct influence on shaping a student's overall attitude is generally less impactful than the other factors mentioned.
