After going through the manuscript, I made the following observations:

1. There are issues with the following citations:

• Capar, & Tarim, K (20150----Not properly cited
• Gottschall & Garcia-bayonas (2008)---Be consistent with the first letter in Bayonas.
• Johnson & Jonson (2000)----Check reference again. It is missing a comma.
• McCorkle, Reardon, & Alexander (1999)------  Not in reference or check the second author’s name.
• Ruiz-Gallardo, López-Cirugeda & Moreno-Rubio (2012)----- Not properly cited. Check the commas.

2. The following references are either not cited or properly cited:

• Johnson & Johnson (1992)
• McCorkle, Diriker, & Alexander (1992)
• National Council of Teachers of Mathematics (2014)----Not cited.
• National Council of Teachers of Mathematics (1988)----Not cited.
• National Council of Teachers of Mathematics (2014)----Not cited.
• Thanh, Gillies, & Renshaw (2008)----Please check when to use “et al.” in in-text citations.

Greetings Mahati and Dianne,

Like Abdel, I noted several APA miscues in citation and punctuation, but I would like to confine my comments to the paper itself; i.e., the information and presentation of that information in the paper. The following comments are offered as suggestions that I think would improve the content and presentation of the essay. 

1. The term "pre-service teachers' group" should be specifically defined early in the essay. (We may understand what you have in mind, but a definition would remove possible doubt and ambiguity.)

2. You seem to be making a distinction between "co-operative learning" and "group work," but that distinction is not specifically laid out in the essay. As the essay progresses, the terms are often used almost interchangeably; thus, the benefit of one over the other is obscured. 

3. You did a good job of pointing out the differing classroom arraignments between Dr. Daisy and Dr. Sunshine, and how those arraignments contributed to a feeling of comfort and community among the students. 

4. The sample size is far too small to yield pertinent data that can be applied to a much larger population and to other disciplines. The data would be more beneficial if a survey of some sort could have been given to those students who did not wish to participate in the interview process; data could then have been extrapolated that would yield results from a much larger sample group. 

I appreciate you hard work, and can see the benefit of using structured cooperative group assignments for classrooms.

Have a blessed day,

Ron Steadman
