Thitirat, be aware that if you copy phrases from another author, you must put quotation marks around that phrase to show that it is not your writing. For example, the phrase "the wealthy plantation owners sought to reduce the growing number of bitter ex-servants so as to avoid future uprisings. So, just at the point the plantations were beginning to expand, their access to indentured workers declined. The terrible solution was the importation of African slaves." I see that you tried to point out the source in parenthesis afterwards, but there were no quotation marks to show where your writing ends and the quote begins. There are also some phrases in the second paragraph that are direct from the course reading. This is considered plagiarism, so please make sure that you are writing the assignments entirely in your own words. This class will help you practice your writing skills. In general, try to keep the quotations to a minimum, even if you do properly punctuate and credit them.
