If a researcher studies the effectiveness of anti-drug commercials by comparing the self-reported frequency of drug use among teens six months before and six months after the commercial aired, she is using an Pretest/posttest design.
Answer: Option D
<u>Explanation:</u>
The pre-test is defined as a test carried out on a product or service before it is set to enter into the market for sale. It is usually done to check not only the effectiveness and efficiency of the product or service but also to check the safety of it too.
Sometimes a product or service is exposed to text after it enters the market. This is known as post-test as that is carried out after the product enters the market.
The correct answer is answer 4 ("It stopped all aggression on both sides").
The Treaty of Ghent ended the War of 1812 between Great Britain and the United States. After both sides signed it, the borders of the two nations were restored to the lines that standed before the conflict had started, and it marked the beginning of over two centuries of peace between them.
It was signed during the Battle of New Orleans, <u>not after</u>. The news took about a month to reach the places in combat, but <u>peace had already been signed before the US won that battle</u>.
<u>Native American hostilities continued for many years to come.</u>
After the war ended and the treaty was signed, <u>the United Kingdom still retained many north american territories that were under their domain before.</u>
Hope this helps!
Answer: Jean Piaget's theory of cognitive development suggests that children move through four different stages of mental development. His theory focuses not only on understanding how children acquire knowledge, but also on understanding the nature of intelligence
Piaget believed that children take an active role in the learning process, acting much like little scientists as they perform experiments, make observations, and learn about the world.
