I don't know if it is fair for the researchers to judge their study based on this article when it does not give us every detail in the actual study. However, I will try to mention some points that I believe are important and the researchers either did not cover it completely or missed it at all.

The first thing that I have noticed about this article that you need to go through a lot of background information before you get to the purpose of the study - maybe the researchers thought that since they stated their purpose as the title of the article it was enough- which I believe should be the first thing you should start with. In addition, even when I have found the purpose of the study I could not understand it completely due to the fact that it has many terminologies that needed to be defined, which the researchers missed or though it do not need to be defined. However, in the both possibilities obviously they were wrong. More over, the researchers did not state a clear hypothesis or research questions, I had to search for it and try to figure it out which I believe should not be my job to search for information that had to be stated clearly.

Finally, the title of the article adequately described the content of the study, and the research was kind of discussed clearly and was sort of easy to follow. References were cited appropriately in the text and accurately listed in the reference list.

At the beginning of the article it says that subjects were giving the opportunity to switch to the control group, thus, no one choose to do so, so I expected the article to show me how would the researchers handle the possibility of missing subjects. - What would happen if 80% of the experimental sections choose to switch? -. However, the article did not provided any information in this regard.

Sample is representative or not. Instead the article stated that " the sample was taken from student enrolled in intermediate algebra course at a large state university with approximately 28,000 students".

The article mentioned that the researchers did not find differences among the subject in the experimental group and the control group except for the part of the gender. There were more females than males. Which I believe could directly affect the result of
