You can edit the appearance of your references list in Word. In Word, click on the EndNote 21 tab and select the tiny arrow on the bottom right side of the bibliography section:

In the popup, click on the Layout tab and modify the options (font, font size, title of references section, numbering or indent). If you have followed the steps above, you most likely only need to adjust the font, size and bibliography title to your liking or professor's specifications.
