Final answer:
Research supports the truth that engagement promotes higher performance in various settings, including education and employment, as it is linked to better learning outcomes and productivity.
Step-by-step explanation:
The claim that engagement is the key factor that promotes higher performance in educational settings is true. Studies support that impactful engagement, such as student effort and participation, contributes positively to learning outcomes. For instance, Heckert et al.'s (2006) research found that courses requiring higher levels of student effort were evaluated as more valuable and that students felt they learned more in these courses. These findings echo the sentiment that engagement, beyond simply participating, plays a crucial role in both perceived and actual academic success.
Moreover, when considering the role of engagement in a broader context, such as employee productivity, human interaction factors like supervisorial style again show a significant impact on performance. Therefore, it's not just in educational settings that engagement is essential; its influence is pervasive across different domains where performance is measured.
