It seems reasonable to suggest that the motivation that students bring to class is the biggest single factor affecting their success?

Indeed, student motivation plays a critical role in their academic success. Motivated students are more likely to engage actively in learning, participate in discussions, and seek help when needed, which enhances their understanding of the material. Furthermore, intrinsic motivation fosters a growth mindset, encouraging resilience in the face of challenges. Therefore, cultivating motivation can significantly influence students' overall performance and achievement in the classroom.
