What instructor action is likely to result in learners becoming frustrated?

When an instructor tells a learner that their work is unsatisfactory without offering any explanation, it can lead to significant frustration for the learner. This action leaves the learner without a clear understanding of what was wrong, making it difficult for them to improve or learn from the experience. Constructive feedback typically involves not only identifying areas that require improvement but also providing specific guidance on how to enhance their performance. This supportive approach helps learners feel valued and understood, and encourages their growth by outlining the path forward.

In contrast, the other actions—providing constructive feedback, engaging learners in discussion, and offering additional resources—are designed to foster a positive learning environment. Each of these actions builds on the learners' understanding and encourages an interactive and supportive educational experience.
