Which instructional practice most effectively communicates high expectations for student learning?

Returning students' work that is not up to standards with suggestions for improvement most effectively communicates high expectations for student learning because it directly addresses the quality of the student's work while also providing constructive feedback. This practice demonstrates that the educator values student learning and believes that each student has the potential to improve. By identifying specific areas where a student can enhance their performance, the educator sets a clear standard of what is expected and encourages a growth mindset. This approach fosters a sense of accountability and motivates students to strive for better results, as they see tangible pathways for improvement and recognize that their current performance is not the final mark of their capabilities. It not only reinforces high standards but also actively engages students in the learning process, prompting reflection and self-assessment.
