Good work, David. I enjoyed reading this blog. Mostly, it is very clear and flows well. A couple of problems:

1) Misuse of semicolon creating sentence fragment: "In academia, writers encounter difficulties with grammar, comma splices, and punctuation. These and other writing errors can be corrected; accordingly, by taking effective measures, practicing regularly, and seeking help."

2) No comma in a list of two. Delete second comma. "As graduate students, we learn to be critical thinkers, and to be rational in our understanding of a subject matter."

3) Delete comma between subject and verb - "The article “Helping students meet the challenges of academic writing”, devotes a paragraph"

4) Awkward. Read aloud - restructure to smoothly incorporate the quotation - “By internalizing and taking up aspects of negative instructor discourses” quotes L.A. Fernsten and M. Reda “some students may come to see themselves as ineffectual writers.”

5) Avoid unmodified this. Always say this what for greater clarity and precision - "This is particularly true..."

Otherwise, good. Keep an eye on those type of errors as you proofread your critical review.
Thanks!

Angie
