Which would more likely result in students becoming frustrated?

The statement that telling students their work is unsatisfactory with no explanation would more likely result in frustration is accurate. When students receive negative feedback without context, they have no opportunity to understand what they did wrong or how to improve. This lack of clarity can lead to confusion and feelings of inadequacy, as students may feel they are being judged without a fair assessment of their work or a pathway to success. Constructive feedback is essential for learning, as it guides students on how to enhance their skills and knowledge, rather than simply discouraging them.

In contrast, while giving meaningless praise might seem counterproductive, it may not evoke the same level of frustration because students may simply dismiss it without feeling attacked or criticized. Similarly, covering up mistakes or bluffing might create a sense of distrust or disillusionment over time, but it doesn't directly impact the students' understanding of their own work in the way uncontextualized harsh feedback does. Providing constructive feedback, on the other hand, is beneficial and essential for guiding students toward improvement and success, rather than leaving them in a state of frustration.
