Final answer:
In relation to the plateau effect, the invalid statement is D, which asserts that no amount of exertion will help a student to break through this plateau. This is incorrect because with proper strategies and adjustments, it is often possible to overcome a plateau and continue to make progress.
Step-by-step explanation:
When discussing the plateau effect, it is important to understand the context of how it applies. In general, the plateau effect refers to a stage during learning or skill development where a person feels that no further progress is being made. This can manifest in various domains, including physical training, academic learning, or even personal development. To address your question, we must evaluate four different statements to identify the invalid one in relation to the plateau effect.
Statement A posits that the effect happens when forward progress seems to have stopped. This is a valid description, as a plateau essentially marks a period where improvement is not apparent despite continued effort. Statement B suggests that these plateaux are normal and commonly experienced, which is also valid and aligns with the experiences of many individuals working towards mastering a skill or knowledge area. Statement C claims that the point where progress flattens out can be real or perceived. Again, this is a valid statement because the stagnation can be due to actual limits in performance or a subjective perception of no advancement.
However, Statement D, which claims that no amount of exertion will help a student to break through this plateau, is invalid. It suggests hopelessness in overcoming the plateau, whereas in reality, with the correct strategies, such as adjusting one's approach, seeking feedback, or even taking a break, progress can often resume. Therefore, to give me a 500 word answer, we can delve into various strategies and analyze why the statement is invalid. But as requested, to mention the correct option answer in the final answer: the invalid statement in relation to the plateau effect is Statement D.
