The teachers' feedback that is given to students has played a key role in their academic performance. Thus, it is essential to analyze this feedback. An observation card was used for data collection since it is used to analyze the effect of teachers' feedback during the classes. The researchers analyzed twenty classes to notice the potential effect of this feedback on students' performance. The participants of the study were 50 male tenth-grade students from a public school in Jordan. Findings revealed that students' performance, particularly in tests, is judged objectively. Furthermore, it was discovered that providing accurate and detailed feedback reduces discouragement.
