Mr. Gregg wants to help his second-grade students improve their reading skills. He
tests the students with 20 reading comprehension questions at the beginning of the
year. Every week throughout the year he gives the students 30 minutes of reading
comprehension tips. He tests the students at the end of the year with 20 reading
comprehension questions that are similar in difficulty to those in the original test. He
finds that the students' reading comprehension has increased and concludes that his
tips worked. Which of the following describes the most significant problem with Mr.
Gregg's study?
A.)Mr. Gregg failed to account for changes in the students' maturity
B.)It was unethical of Mr. Gregg to test the children without their parent's consent
C.)Mr. Gregg should have used the same test to ensure reliability
D.)Mr. Gregg should have had someone else test the children in case he was showing
experimenter bias
E.)Mr. Gregg should have tested his students every month so he could more accurately track their
progress.

The most significant problem with Mr. Gregg's study was that he skipped that the students maturity means brain changes.

During the first years of life, the brain develops a large part of its capacities to 100%. One of them is understanding and understanding. Therefore, children tend to mature over time. One example of this is that they increasingly understand more complex situations and knowledge.

An example of this is the situation presented, in which Mr. Gregg wants to improve the reading comprehension of his second-grade students. However, this process is something that can be done "automatically" thanks to the development of the brain and its abilities.

According to the above, the brain of the second-grade students improved their ability to understand and read comprehension thanks to the process of brain development without having much influence on the advice given by Mr. Gregg.

So the correct answer is A. because it presents the correct information for this situation.
