If you have a 50-page Word doc that has to go into your journal, then usually you place the Word file and Shift-click it in the layout to autoflow it. The reason you always place instead of copy/paste is because you have so much more control via the Word Import Options dialog box. Saves a ton of time. If you just need to grab a paragraph or two, then sure just copy/paste.
I cover this, plus dealing with footnotes and endnotes and other fun Word stuff ;-D in my lynda.com title, Using Word and InDesign Together.

Some people create text frames on the master page and then in the document page, you’d shift-click it in that frame. Other people let InDesign make the frames on the fly based on the margin and column guides. (Just shift-click on the doc page).
If the Word article has captions, a headline, a sidebar, etc., then the typical workflow is to place the whole thing, then you cut and paste from the placed story into those separate/new text frames.
